Spinosaurus: the biggest dinosaur Carnivorous

Spinosaurus was the largest of all the carnivorous dinosaurs, bigger than Tyrannosaurus and Giganotosaurus. It lived during the center of the Cretaceous Period about 112 million to 97 million years ago, roaming the swamps of North Africa.

Two Spinosaurus species have been named based on the region where they were discovered: Spinosaurus aegyptiacus and Spinosaurus maroccanus.

Spinosaurus means "spine lizard," and suitable descriptor, as the dinosaur had very long spines rising on its back to form what is referred to as a "sail." The spines were more than 10 times the length of the vertebrae structures from which they comprehensive and were slightly longer front to back at the base than higher up.

The distinctive spines were about 5.4 feet long and were likely to have been linked by skin. Because the spines were connected by tissue, the structure may also have been more of a huge bulge than a sail, according to German paleontologist Ernst Stromer.

There has been much technical dispute concerning the evolution and purpose of the Spinosaurus' sail. It is probable that the sail served several purposes, including regulating body temperature by fascinating heat, and attracting mates.

Because of its size, the Spinosaurus did not have many predators, but the sail could have been used to ward off enemies, as the dinosaur appeared to be twice its bulk when the sail was entirely extended. Paleontologists theorize that the sails were brightly colored, much like the fins of some latter-day reptiles.

The only straight substantiation that Spinosaurus ate fish was a juvenile exposed with fish scales and bones in its stomach. There is also proof that it preyed on other small herbivore dinosaurs and scavenged.

Discover some amazing dinosaur remains

From tiny trilobites to immense dinosaurs, a wonderful array of creatures has lived on Earth over the past 4 billion years. Deep in the earth around you are the sealed remains of past life. Paleontologists work to show these fossils, which can be many different shapes, sizes, and colors. Usually, fossils are the teeth, bones, or shells of olden animals, but sometimes we find out something even rarer, like fossilized poop.

Fossilized feces are called coprolites, meaning “dung stones.” Coprolites frequently seize clues to an animal’s meal, the atmosphere in which the animal lived, and more. Dino poop — along with coprolites from other dead animals — can tell notable stories about creatures that lived millions of years ago.

 By investigative fossil feces, along with teeth, bones, and sealed stomach contents, scientists can part together how dinosaur carnivores, omnivores, and herbivores ate and digested their meals.

Did Dinosaurs Poop? Is a brand new hands-on exhibition for children opening Sept. 14 at the Museum of the Earth? Considered mainly for families with children ages 4 to 10 but fun for all ages, the exhibition presents a fun and multicolored approach to knowledge about fossils and dinosaur diets.

The museum will celebrate Family Day from 10 a.m. to 1 p.m. Sept. 15 with fun practical activities and two showings at 10:30 a.m. and 1 p.m. of WSKG’s “Dinosaur coach: Every fossil Poops” event.

110 Success Stories for Endangered Species Day 2012

Critics of the Endangered Species Act contend it is a failure because only 1 percent of the species under its protection have recovered and been delisted. The critique, however, is undermined by its failure to explain how many species should have recovered by now. It is a ship without an anchor.

To objectively test whether the Endangered Species Act is recovering species at a sufficient rate, we compared the actual recovery rate of 110 species with the projected recovery rate in their federal recovery plans. The species range over all 50 states, include all major taxonomic groups, and have a diversity of listing lengths.

We found that the Endangered Species Act has a remarkably successful recovery rate: 90 percent of species are recovering at the rate specified by their federal recovery plan.

You can read a copy of the report, “On Time, On Target: How the Endangered Species Act Is Saving America’s Wildlife” here. Click here to see a regional map of species recovering around the country.

On average, species recovered in 25 years, while their recovery plan predicted 23 years — a 91 percent timeliness accomplishment.

We confirmed the conclusion of scientists and auditors who assert that the great majority of species have not been listed long enough to warrant an expectation of recovery: 80 percent of species have not yet reached their expected recovery year. On average, these species have been listed for just 32 years, while their recovery plans required 46 years of listing.

The study’s findings are similar to a 2006 analysis of all federally protected species in the Northeast, which found 93 percent were stabilized or improving since being put on the endangered species list and 82 percent were on pace to meet recovery goals.

When judged in the light of meeting recovery plan timelines for recovery, the Endangered Species Act is remarkably successful. Few laws of any kind can boast a 90 percent success rate.

Loss of rare species can harm ecosystems

Bracken and Brown University student Natalie Low conducted several experiments that analyzed the impact of removing seaweed and sessile animals, such as mussels and barnacles, from the rocky shores of Northeastern’s Marine Science Center in Nahant, Mass. The experiments were designed to mimic naturally occurring changes in biodiversity on rocky shores.

The findings were startling. “We have shown that the loss of these extremely rare species — which collectively represent less than 10 percent of the seaweed and animal biomass at the base of the food web — causes major declines in the abundance and diversity of animals, such as snails, crabs and other mobile animals,” Bracken said. Prior research on the extirpation of rare species from a particular ecosystem focused on how the loss of top predators — often referred to as “keystone” species — affects plants and animals at the bottom of the food chain. Bracken and Low, on the other hand, have shown that the loss of rare species from the base of the food chain, which they call “cornerstone” species, can also reshape marine systems. A pattern of decline emerged after only three weeks of experiments and persisted for the remainder of the five–week study. “Previous work on the effects of rare predator removals took months to years to show strong effects,” Bracken said. “We found strong effects of rare seaweed removals after only a few weeks.”

Modern Birds are actually Baby Dinosaurs

Modern birds hold the physical individuality of baby dinosaurs, according to a new Nature study that found birds are even more closely linked to dinosaur than before thought.

Depending on the non-avian dinosaur and bird compared, that might be tough to consider. When researchers go beyond the surface to the tissue and skull levels, however, the similarities become extra obvious.

"The evaluation of the many characteristics of birds –- things like feathers, flight, and wishbones -– has usually been a hard problem for biologists," Mark Norell, chair of the division of paleontology at the American Museum of Natural History and one of the paper's co-authors, added.

"By analyzing fossil proof from skeletons, eggs, and soft tissue of bird-like dinosaurs and primitive birds, we've learned that birds are living theropod dinosaurs, a group of carnivorous birds that include Velociraptor," Norell sustained.

"This new work advances our knowledge by providing an authoritative example of how developmental changes played a main role in the source and development of birds."

Science casts a fresh eye on dinosaur history

Much of what we thought we knew about dinosaurs is altering as fresh science creates new pictures of these antique creatures and how they lived.

New discoveries of smaller dinosaurs from China have exposed many were enclosed in feathers. Paleontologists now consider many dinosaurs were warm-blooded and some even lived in areas that saw snow.

"What you used to think about dinosaurs, maybe you should imagine about them in a different way," says Richard Hebda, paleontologist with the Royal B.C. Museum, where the travelling show Dinosaurs, antique Fossils, New Discoveries opens Thursday.

 "It tries to offer a look at how these organisms lived and behaved and there is  a bit on what type of world they lived in."

The show, assembled by the famous American Museum of Natural History in New York City, runs until Sept. 16 in Victoria.

Scientists now consider dinosaurs were much more active than the ponderous, giant lizards once imagined. Instead of spending most of their time in water to support their giant size, they likely ran, jumped and even migrated over dry land.

Long-necked dinosaurs were before pictured living and feeding from treetops with their necks extensive straight upwards, like giraffes.

Robotic Dinosaurs on the technique for Next-Gen Paleontology

Researchers at Drexel University are bringing the newest technical advancements in 3-D printing to the study of antique life. Using scale models of real fossils, for the first time, they will be able to check hypotheses about how dinosaurs and extra primitive animals moved and lived in their environments.

"Technology in paleontology hasn't tainted in about 150 years," said Drexel paleontologist Dr. Kenneth Lacovara, and relate professor in the College of Arts and Sciences. "We use shovels and pickaxes and burlap and plaster. It hasn't distorted until now."

Lacovara has begun creating 3-D scans of massive dinosaur bones and other fossils in his lab. The 3-D scan puts a virtual picture in a digital workplace that researchers can control and analyze.

To transport these scans to life, Lacovara is also teaming up with mechanical engineer Dr. James Tangorra, an assistant professor in Drexel's College of Engineering, to use 3-D printing technology to make and check scale models of fossil bones.

A 3-D printer is a technology for fast prototyping and developed objects based on a digital design. Common models work by regularly extruding very thin layers of a resin or added material, building up strata to make a physical object.

Twinky the baby dinosaur arrives in Singapore

It exhausted one month at sea, journeying from the jagged, liberal and frosty American state of Utah to the flat, little and tropical island of Singapore.

And last Wednesday nighttime, Twinky, the baby dinosaur, arrived in its adopted land - packed in 12 crates on a 20-foot container.

But it will be a while before Singapore will reveal the unusual 12m long discover at its new home, as the yet-to-be-built Lee Kong Chian Natural History Museum will be prepared only in two years' time.

The 7,500 sq m purpose-built museum at the National University of Singapore (NUS) will house not just Twinky and two bigger dinosaurs, but also one of the major collections of South-east Asian animals in the county.

For now, Twinky will stay patiently in an unnamed temperature-controlled and protected warehouse for its star turn - and the arrival of its 'parents'.

Twinky, Apollo and Prince were set up buried mutually in a quarry in Wyoming between 2007 and 2010.

Duck-Billed Dinosaurs Endured extensive, dim Polar Winters

Duck-billed dinosaurs that lived within Arctic latitudes about 70 million years ago probable endured extensive, dark polar winters instead of migrating to more southern latitudes, a new study by researchers from the University of Cape Town, Museum of natural world and Science in Dallas and Temple University has found.

The Museum of Nature and Science, a paleontologist Anthony Fiorillo excavated Cretaceous Period fossils along Alaska's North Slope. Most of the skeleton belonged to Edmontosaurus, a duck-billed herbivore, but some others such as the horned dinosaur Pachyrhinosaurus were also found.

Fiorillo hypothesized that the microscopic structures of the dinosaurs' skeleton could prove how they lived in Polar Regions. He enlisted the aid of Allison Tumarkin-Deratzian, an assistant professor of earth and environmental science, who had both skill and the services to make and check thin layers of the dinosaurs' bone microstructure.

"The bone microstructure of these dinosaurs is really a record of how these animals were rising throughout their lives," said Tumarkin-Deratzian. "It is about alike to looking at tree rings."

Enigmatic Dinosaurs egg discovered in Patagonia

An Argentine-Swedish explore team has reported a 70-million-year-old pocket of fossilized bones and unique eggs of an enigmatic birdlike dinosaur in Patagonia.

"What makes the discovery unique are the two eggs sealed near articulated bones of its hind limb? This is the first time the eggs are originated in a seal proximity to skeletal remains of an alvarezsaurid dinosaur," says Dr. Martin Kundrat dinosaur specialist from the group of Professor per Erik Ahlberg at Uppsala University.

The dinosaur represents the newest survivor of its kind from Gondwana, the southern island in the Mesozoic Era.

The creature belongs to one of the strangest groups of dinosaurs, the Alvarezsauridae, and it is one of the major members, 2.6 m, of the family.

The two eggs establish mutually with the bones during the journey might have been inside the oviducts of the Bonapartenykus feminine when the creature perished.

"During examination of the shell samples using the electron scanning microscopy observed strange fossilized substance inside of the pneumatic canal of the eggshells. It twisted out to be the first proof of fungal contamination of dinosaur eggs.

Shaggy T. Rex Cousin Was Heftiest Feathered Dinosaur

The recently unearthed tyrannosaur, named Yutyrannus huali or "stunning feathered tyrant," lived about 125 million years ago in northeastern China. The over 29-foot-long non-avian dinosaur, represented by three specimens, is significantly smaller than its notorious relative T. rex.

"The largest specimen conserve feathers on the tail, and two lesser specimens protect feathers over the neck, on the forelimbs, near the pelvis, and even feet," lead author Xing Xu, a lecturer at Beijing's Institute of Vertebrate Paleontology and Paleoanthropology, said.

Xu and his colleagues analyzed the remains of the three dinosaurs and exposed that patches of filamentous structures were near the frame on the slabs containing the specimens.

The researchers consider that when the dinosaurs were alive, these easy structures would have been additional like the hairy down of a contemporary infant chick than the stiff plumes of a mature bird.

"The dimension, structure and extent of the feathers suggests that they would have shaped a shaggy body covering that would have had at least some insulating purpose,"

Fossils of dicynodont exposed on each continent

Fossils discovered on a Tasmanian beach have established the survival in Australia of the dicynodont – an odd-looking species that lived 30 million years previous to the dinosaur – proving it existed on all continents.

The fossils were established by a pair strolling on a seaside on the Tasman Peninsula. The plant-eating animals, about the size of a cow, lived about 250 million years ago and became destroyed about 20 million years ago.

Complete specimens of the dicynodont have been establishing in India and South Africa. The detection of the two skull pieces found in Tasmania has enabled scientists to verify that the creature lived in Australia. The only other proof was a fossil found in Queensland in 1983.

A paleontologist of Queensland Museum, Dr Andrew Rozefelds said the "strange-looking beast” may have survived longer in Australia than on other continents.

Australia is an island continent and perhaps some things like the monotremes, like the platypus and the echidna, survived here as elsewhere in the earth they became extinct.

Small Four-Winged Dinosaur Sported Shimmery Black Feathers

A new fossil of a four-winged dinosaur concerning the dimensions of a pigeon shows he apparently sported quite the costume, complete with shiny black feathers and a tail tipped with a combine of ornamental streamer feathers.

The newly exposed fossil of Microraptor lived about 130 million years ago, through the early Cretaceous period, in what is nowadays northeastern China.

The researchers compared the agreement of these melanosomes with those of modern birds. When melanosomes are stacked tidily, the feather looks darker; when they are further muddled, the feather appears lighter.

From their analysis of modern birds, the researchers figured that this Microraptor fossil had black feathers. In addition, the narrow stacking of the melanosomes would have known the feathers iridescence.

The researchers couldn't be sure of the dye of the sheen, or the result of the iridescence on the quill color, because those factors depend on the width of the feather's keratin coat.

Collection of huge dinosaur bone found

The enormous scrape bone of a big meat-eating dinosaur has been exposed at Lightning Ridge, in the collection of the Australian Opal Centre.

One hundred million years ago at Lightning Ridge, a big dinosaur with hideous hand claws roamed the forests. This was a frightening huntsman that caught and slashed its quarry with claws like grappling hooks.

The bone is decomposed along one surface, but when absolute it would have been about 15 centimeters extended.

“We can recognize it by comparing it to extra scrape bones in the AOC set, and by referring to dinosaurs from elsewhere in Australia and overseas,” Elizabeth said.

The Carters Rush dinosaur was maybe four metres lengthy and up to three metres high at the trendy, same in size to Allosaurus from North America. This is the main theropod dinosaur ever exposed in NSW, and one of Australia’s biggest therapies.

Awesome Dino had comical Arms

With its blade-like teeth and frightening claws, Majungasaurus crenatissimus was one of the world’s most formidable predators, but new study reveals that it also obsessed some of the animal kingdom's negligible and most peculiar arms.

Tyrannosaurus rex and other well known greedy dinosaurs also had condensed forelimbs. While Majungasaurus, which lived 66 million years ago in Madagascar, was not a close T. rex family member, some lifestyle factors might have caused them to develop convinced similarities.

"The development of small arms in greedy dinosaur’s remains secrecy, but fossils like this is a significant sign in understanding the process,"

"Only by discovering the stops foremost from 'normal' longer arms in the family forms, to the short and strange ones in Majungasaurus and its close relatives, can we trust to clarify the evolutionary series and its causes."

The forearm skeletons are only a quarter of the length of the higher arm bones, but would have been broad and brawny. The wrist bones, however, aren't even ossified, and the short fingers probably lacked claws.

Older fossils resolve secrecy of earliest bird extinction

The meteorite crash that coincided with the vanishing of the dinosaurs 65 million years ago also saw a fast refuse in prehistoric bird species.


Only a little bird groups survived through the accumulation death, from which all contemporary birds are descended.

There has been a long standing argue over the destiny of the earliest "archaic" birds, which first evolved about 200 million years ago.

Whether their populations declined gradually towards the end of the Cretaceous time, or whether they suffered unexpected accumulation extinction at the Cretaceous-Tertiary (K-T) boundary is unsettled, owing to contradictory evidence.

DNA studies have attempted to date the source of contemporary birds; some propose that they appeared before the extermination of dinosaurs, with big facts of them existing through the extermination affair.

Bird bones are very hard to protect as fossils as they are little and glow, and easily injured or swept away in rivers.

But the new investigate, headed by Dr Longrich, have made use of fragmentary bird fossils composed up to 100 years ago, from locations across North America.

Love Song of an old Jurassic

The love song of an extinct out katydid that lived 165 million years ago has been brought rear to existence, according to a revise in the newest topic of PNAS. The song is consideration to be the majority antique known melody recognized to date.

The song was reconstructed from microscopic division skin tone on a fossil exposed in North East China. It allows us to pay attention to one of the sounds that would have been heard by dinosaurs and other creature’s nomadic Jurassic forests at night.

An absolute work of usual sounds must have filled the world 165 million years ago, with prehistoric crickets and croaking amphibians most important the way. These were amongst the primary animals to create noisy sounds by stridulation, or resistance certain body parts jointly.

Katydids create mating calls by rubbing a line of teeth on single division against an addition on the additional wing, but how their prehistoric intimates shaped sound and what their songs really sounded like was unidentified until now.

Biggest creature Once Roamed Antarctica

The sauropod family includes some of the main earthly vertebrates that still existed -- huge, awkward beasts weighing tens or still hundreds of plenty. And they lived all over but Antarctica, paleontologist’s thought -- until now.

Argentinean researchers have just exposed the Antarctic leftovers of a titanosaur, a plant-eating, sauropod dinosaur that leftovers one of the main creatures to still trudge the outside of the earth.

In spite of the huge size of the creatures, the proof was extraordinarily little: Just a section of spine hardly 7.5 inches long supposed to have approach from the center third of the dinosaur's tail.

These sauropod dinosaur leftovers from Antarctica improve our present information of the dinosaurian faunas throughout the Late Cretaceous on this continent," said Ignacio Alejandro Cerda from Argentinan science foundation CONICET, who was part of the squad that exposed the remains of the "lithostrotian titanosaur." The huge creature lumbered around approximately 70 million years ago.

Other significant dinosaur discoveries have been made in Antarctica in the previous two decades -- mainly in the James Ross Basin where this small piece of bone was originate, the scientists noted.

A formidable dinosaur — with strange small ineffective arms

The huge, cannibalistic dinosaur had such uneven arms that it could not have grasped anything or even injured its own face, according to a new study published in the Journal of Vertebrate Paleontology.


Tyrannosaurus rex and other well known greedy dinosaurs also had reduced forelimbs. While Majungasaurus, which lived 66 million years ago in Madagascar, was not a close T. Rex Relation, some lifestyle factors might have caused them to develop certain similarities.

"The development of small arms in greedy dinosaur’s relics a secrecy, but fossils like this are a significant clue in sympathetic the procedure," co-author Matthew Carrano, a paleobiologist at the Smithsonian Institution.

The forearm bones are only a district of the length of the higher arm bones, but would have been broad and brawny. The wrist bones, however, aren't even ossified, and the short fingers probably lacked claws.

"Only by discovering the stops foremost from 'normal' longer arms in the ancestral forms, to the small and strange ones in Majungasaurus and its close relatives, can we hope to explain the evolutionary series and its causes."

New dinosaur, Yueosaurus Tiantaiensis, found in China

Scientists have recognized an innovative species of dinosaur, Yueosaurus Tiantaiensis or "Tiantai Yue Dinosaur," from a fossilized skeleton originate in eastern China.


It took five Chinese and Japanese researchers more than three years of concentrated study to recognize that the frame belonged to a divide species, according to geoscientist Zheng Wenjie of the Zhejiang Museum of Natural History.

They consider it is a before unknown species of ornithischian, or "bird-hipped" dinosaur, that lived throughout the Cretaceous period a number of 100 million years ago. It had a bill, ate plants and was intelligent to run fast on two legs to flee predators, Zheng said.

At concerning 1.5 meters long and less than 1 meter high, Yueosaurus is the minimum dinosaur yet exposed in the region.

Dinosaurs of its type – bipedal, herbivorous runners known as ornithopods – were exceptional in Asia; previously, only four such species had ever been establish on the continent.

Yueosaurus is the fifth new dinosaur species to have been found in Zhejiang.

Dinosaur footpath originate in Beijing’s community

Hundreds of dinosaur footpath from the Late Jurassic (about 140 million to 150 million years ago) has been originate along the core zone of Yanqing Silicified Wood National Geopark by Zhang Jianping, a geologist from China University of Geosciences through his field work late 2011.

The tracks range in length from 15 to 60 centimeters and were laid about 150 million years ago in what is now the Yanqing Silicified Wood National Geopark, near 15 kilometers from the town of Beijing’s north suburban Yanqing county.



"As they are exceptional, high-speed theropod tracks disclose aspects of their paleoethology,” said Zhang Jianping. “The dinosaur tracks from Yanqing comprise the initial proof of dinosaurs in Beijing and as the mine continues, there could be more track findings.”

A dinosaur geopark will be built in the area where the dinosaur footpath is found, according to Yuan Guixu, director of Yanqing Tourism management. “Once the dinosaur park is finished, it will unlock to the tourists,” said Yuan.

New species of dinosaur discovered in museum

Bone-bothering boffins have exposed a totally brand new species of horned dinosaur , in spite of having parts of its skull for the last hundred years.

The fossilized remains of parts of the skull of the Spinops sternbergorum were exposed in 1916 by father-and-son fossil-collectors Charles and Levi Sternberg. They thought they had establish a brand new species and sent the fossils to the Natural History Museum in London.

But the museum determined that the fossils were too little to be exhibited, so they were filed away for decades. Andrew Farke, guide author on the study that named the Spinops, said in a statement.

"My colleagues and I were enjoyably amazed to discover these fossils on the museum sill, and even more surprised when we resolute that they were a previously unidentified species of dinosaur."

The Spinops lived approximately 76 million years ago in Canada. The dinosaur was a plant-eating slighter cousin of the Triceratops that weighed approximately two tons.The primitive lizard had a solitary horn on its nose and a skinny neckline decoration that had at least two long, backward-projecting spikes as well as two forward-curving hooks, which are the sole skin that differentiate it from other horned dinosaurs.

Although Spinops' face looks very like to that of its close relatives Centrosaurus and Styracosaurus, the bony neck frill gives boffins a improved sympathetic of how this structure evolved.

"In particular, the fossils of Spinops explain the recognition of the extended frill spikes ordinary in some horned dinosaurs,"

Dinosaurs approaching to junior Museum of Memphis

The museum announced Monday that the roving show, "Dinosaurs : Land of flames and frost," will open Feb. 11. The show is sponsored by Cordova-based Kronos power Solutions.The museum is being retrofitted -- with ramparts taken down and festivity accommodation prolonged to create liberty for what officials anticipate will be a rush in company.

"In the show world, this is measured a hit," said museum CEO Dick Hackett. "It'll have provincial magnetism."A $2 supplement will be additional to the usual $10 admittance cost throughout the exhibit's sprint through May 13.

School groups that create reservations by Jan. 31 will get an inexpensive tempo of $4.50 for each child.Along with the dinosaurs, the interactive show features a meadow investigate station, where visitors can expose fossils with brushes and make drawings of the antique reptiles, and the primitive dinosaur home, where children can wear bug costumes and discover a volcano.

The show was shaped by the Minnesota Children's Museum.Hackett said the museum has for years required to transport in a excellence dinosaur show one that doesn't now engage motionless dinosaurs that snarl and accredited Kronos with manufacture it probable.

"It's very good-looking not only to the young people, but also to the teachers and parents and adults that bring the children," Hackett said.

Supersede power ended Twin-Horned Dinosaur a very fast runner

A meat-eating dinosaur that terrorized its plant-eating neighbors in South America was lots deadlier than first thought, a University of Alberta canvasser has found. Carnotaurus was a seven-meter-long marauder with a massive tail power that U of A paleontology mark off student Scott Persons says created it one in all the fastest running hunters of its time.

A secure assessment of the tail frame of Carnotaurus showed its caudofemoralis power had a sinew that emotionally involved to its higher leg bones. Flexing this power pulled the legs backwards and gave Carnotaurus more authority and speed in each footstep.

People assessment of the tail of Carnotaurus showed that along its span were pairs of high rib-like frame that interlocked with the after that couple in row. Using 3-D computer models, Persons recreated the tail muscles of Carnotaurus. He establishes that the strange tale ribs supported an enormous caudofemoralis power.

The interlocked bone arrangement the length of the dinosaur's tail did there one problem: the tail was unbending, creation it hard for the seeker to make rapid, liquid turns.

Persons say that what Carnotaurus gave up in maneuverability, it made up for in directly in face rate. For its size, Carnotaurus had the main caudofemoralis power of any known animal, living or dead.
