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.

New dinosaur detect on Alaska's North Slope by Scientists

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.

Adult Dinosaur Skull Secrets

Wilson an assistant professor in the Department of Geological Sciences and an assistant curator at the U-M Museum of Paleontology said that a dinosaur Diplodocus by name had an unusual skull.

The small Diplodocus skull, however, suggests that the most important changes taken place in the skull throughout the animal's life.

Examination of the youngest and most absolute dinosaur skull of any kind of tyrannosaur discovers significant differences between the young and old of the same species.

A 2-3 year old Tarbosaurus skull was discovered in Mongolia in the year 2006 which is 29 centimeter long skull which is a part of an almost entire skeleton that’s missing only the neck and a part of the tail. It tends to be a close relative of the North American Tyrannosaurus Rex a giant meat-eating predator that lived 70 million years ago.

Ohio demonstrated the structural distinction between the youthful predators and their fearsome elders with the assist of CT scans. It is examined that the skull is relatively delicate and wouldn’t have been able to hold up the kinds of thrashing about and powerful sorts of actions that the adults have. So what this creature must have done is have a very different kind of hunting approaches.

The adults use their supremacy and mass to kill large prey. Witmer says the adolescent were alert and skillful individuals.

There is a clue from a Tyrannosaur species is that some of these young animals actually palled around in groups of juveniles which is a sort of rambling gangs of young tyrannosaurs potentially avoiding the adults.

A sophisticated picture of ecosystems gives us a clear idea in terms of who was eating whom.

In the past it has been said that the Tarbosaurus as a class was the one predator.

But right now it has been thought that Tarbosaurus in fact presented in a sense, multiple kinds of predators.

Witmer expects more secrets will be revealed from the young Tarbosaurus skull.
