New dinosaur detect on Alaska's North Slope by Scientists

Dinosaur News
There’s brand new kind dinosaur out there, and it lived in Alaska.Its bones, long turned to stone, are part of a cliff in northern Alaska. That’s where dinosaur-hunter Tony Fiorillo brushed dirt far from a little of its large skull, one thing that most of us would mistake for a rock.

The year was 2006. The month of August and summer had fled the Colville River, if it had been there at all. Dinosaur hunter Fiorillo, where he works at the Museum of Nature & Science, he visits Alaska each summer from Dallas, remembers climbing from his tent with a heavy head every morning.

On one wet, miserable day, Fiorillo was sticking to a hillside higher than the river; speak actually the soil gently with a trowel. Noticing an uncommon lump, he picked up a brush to softly whisk the dirt away. Suddenly, a complete skull came into focus, and he felt a warm flush of discovery. “When I had that moment of recognition, only (a large nasal bone) was exposed,” Fiorillo said. “But in my mind I could see the rest of the skull.”

Fiorillo was excited because he could tell the specimen was one of the rare ones intact enough to be displayed in a museum, and the Museum of Nature & Science in Dallas was then planning a new building. As he and his digging partners, including Paul McCarthy of the Geophysical Institute and the University of Alaska Fairbanks Geology and Geophysics Department, unearthed the skull and coated it in plaster for a helicopter ride out, Fiorillo didn’t know they had found a species unknown to science.

The dinosaur, that lived in northern Alaska about seventy million years ago, is a plant eater with an enormous shielded head that looked something like a Triceratops, only without a horn extending from its nose. Its mouth resembled a giant parrot’s beak.

Dinosaur Might Buried Alive

Dinosaur

Sauropodomorph an herbivorous, long necked dinosaur has been discovered at Utah's red rocks.

The dinosaur was seemed to be buried, perhaps while it was still living, via collapsing sand dune.

The buried residue symbolizes the Utah’s oldest most complete dinosaur.

A sand dune was collapsed during the Early Jurassic Period, at Utah's red rocks with such power that it might have buried alive a plant-eating dinosaur, by placing the dead body in the tomb and preserving the dinosaur upside-down for 185 million years, according to a novel published in the journal PLoS ONE.

The dinosaur has been named as Seitaad ruessi in which the first word represents a Navajo creation legend sand-desert monstrous that consumed individuals in the dunes. The next word honors the artist and explorer Everett Ruess, who died strangely at the age of 20 in the similar area during the 1930s.

Ruess' body has not at all been found, but the fossils of the original dinosaur froze the animal's ultimate moments. A CT scan makes known that the dinosaur was missing a particular toe and a lower leg bone, suggesting that it either died and was shortly thereafter swallow up by a collapsing sand dune, or was buried alive.

Plesiosaur – Gives Single Birth in Water

Plesiosaur Dinosaur
Plesiosaur a kind of dinosaur is defined as one which has a giant, long-necked swimming reptile and has been lived for a period of about 78 million years ago. It is a kind of carnivorous marine reptile.
After the detection of plesiosaurs, it is said that it resembles a snake threaded through the shell of a turtle, even though they had no shell. Their skeletons were first found in England by Mary Anning before the period of early 19th century. And it is the first fossil vertebrates to be illustrated by science.
This unique dinosaur has determined a long-held secrecy about the animals and how they reproduced.
As per the scientists those marine livings of ancient seas such as modern whales and dolphins are actually gave birth to their newborns beneath the water one at a time, and could have cared for them much as modern whales do.
Many creatures in the marine reptile world of that period shows that they gave birth to a dozen or more at a time but plesiosaur is the first to show proof of a single birth and only in the water, according to the paleontologists.

New species of Dinosaur found in India

U.S. and Indian scientists said Wednesday they have exposed a new carnivorous dinosaur species in India after finding bones in the western part of the country. The new species of dinosaur was named Rajasaurus narmadensis, or "Regal reptile from the Narmada," after the Narmada River region where the bones were found. The dinosaurs were between 25-30 feet long, had a horn above their skulls, were comparatively heavy and walked on two legs, scientists said. They preyed on long-necked herbivorous dinosaurs on the Indian subcontinent for the Cretaceous period at the end of the dinosaur age, 65 million years ago.

"It's tremendous to be able to see this dinosaur which lived as the age of dinosaurs came to a close," said Paul Sereno, a paleontologist at the University of Chicago. "It was an important predator that was related to species on continental Africa, Madagascar and South America."A model of the assembled skull was presented Wednesday by the American scientists to their counterparts from Punjab University in northern India and the Geological Survey of India in a Bombay news conference.


Scientists said they expect the discovery will help explain the extinction of the dinosaurs and the shifting of the continents - how India separated from Africa, Madagascar, Australia and Antarctica and collided with Asia. The dinosaur bones were discovered throughout the past 18 years by Indian scientists Suresh Srivastava of the Geological Survey of India and Ashok Sahni, a paleontologist at Punjab University.

When the bones were scrutinized, "we realized we had a partial skeleton of an undiscovered species," Sereno said. The scientists said they consider the Rajasaurus roamed the Southern Hemisphere land masses of present-day Madagascar, Africa and South America. "People don't understand dinosaurs are the only large-bodied animal that lived, evolved and died at a time when all continents were united," Sereno said.

The cause of the dinosaurs' death is still debated by scientists. The Rajasaurus discovery may give crucial clues, Sereno said. India has seen quite a few paleontological discoveries newly. In 1997, villagers exposed about 300 fossilized dinosaur eggs in Pisdura, 440 miles northeast of Bombay that Indian scientists said were laid by four-legged, long-necked vegetarian creatures. Indian scientists said the dinosaur embryos in the eggs may have suffocated at the period of volcanic eruptions.

Era of Thalattosaur Skeleton

Thalattosaur Skeleton

Thalattosaurs an ocean lizard which lived during the mid-late of Triassic period Belongs to a group of marine reptiles. Its fossil skeleton which was 20 million year old was found in Alaska along the sea shore of a low tide near Tongass National Forest. It is very unique that one could not expect to see on a day at the beach.
According to International Business Times, Alaskan scientists determined that the skeleton was of a rare marine creature and being sunken in water and rocks, called Thalattosaurs. The last survive of this creature was from about 200 million years ago.
The next is about scientists who are continuing to dig out the remaining of the fossils along with finding the skull which may be hidden deep into the beach rocks. They were able to excavate two huge slabs of rocks with fossils embedded. The digged slabs were sent to a museum lab in order to chip out the fragile bones in trust of enlightening one of the most complete Thalattosaur skeletons yet discovered.
Dr Jim Baichtal, a geologist and part of the discovery team, said The Daily Mail that finding the skeleton was a total surprise.

Two-legged Dinosaurs were peace-loving veggies

Most violent two-legged Dinosaurs became peaceable vegan, according to new research, writes Geoffrey Lean.

Scientists at Chicago's Field Museum studied the diet of 90 species of theropods – colloquially called "predatory dinosaurs", which in a lot of cases became the ancestors of modern birds – examining the teeth, fossilised dung (the mind boggles) and stones in the stomach that had been used to grind vegetation.


They establish that even though the therapods' bodies still made them ideal hunter-killers – which is how leading scientists had believed they remained until they became extinct – most species, in fact, turned vegetarian.

"Somewhere on the line to birds," says the familiar researcher, Dr Lindsay Zanno, "predatory dinosaurs went soft." Ultimately, they developed toothless beaks.

Another study, by the University of Texas, augments the image of the peace-loving dinosaur by challenging another conventional view – which they took over the world by driving out other animals. Instead, it seems, they were "humbler, more opportunistic creatures" that took benefit of a mass extinction 200 million years ago. "They didn't invade the neighborhood," says Prof Tim Rowe. "They waited for the inhabitants to leave and then moved in when no one was watching."
