Fires and floods key to dinosaur island secrets

1000pa (Aug. 24, 2010) — Fires and floods which raged across the Isle of Wight some 130 million years ago made the island the richest source of pick 'n' mix dinosaur remains of this age anywhere in the world.

A new study has revealed the Island's once violent weather explains why thousands of tiny dinosaur teeth and bones lie buried alongside the huge bones of their gigantic relatives.

The research was carried out by University of Portsmouth...

Mosasaur fossil: Life of 85-million-year-old 'sea monster' illuminated

1000pa (Aug. 10, 2010) — One of the ocean's most formidable marine predators, the marine mosasaur Platecarpus, lived in the Cretaceous Period some 85 million years ago and was thought to have swum like an eel. That theory is debunked in a new paper published August 10 in the journal PLoS ONE. An international team of scientists have reconceived the animal's morphology, or body plan, based on a spectacular specimen housed at the Natural...

Triceratops and Torsaurus were same dinosaur at different stages

1000pa (July 14, 2010) — Research by a Montana State University doctoral student and one of the nation's top paleontologists is upending more than 100 years of thought regarding the dinosaurs known as Triceratops and Torosaurus.

Since the late 1800s, scientists have believed that Triceratops and Torosaurus were two different types of dinosaurs. Triceratops had a three-horned skull with a rather short frill, whereas Torosaurus had a much...

Mojoceratops: New dinosaur species named for flamboyant frill

1000pa (July 8, 2010) — When Nicholas Longrich discovered a new dinosaur species with a heart-shaped frill on its head, he wanted to come up with a name just as flamboyant as the dinosaur's appearance. Over a few beers with fellow paleontologists one night, he blurted out the first thing that came to mind: Mojoceratops.

"It was just a joke, but then everyone stopped and looked at each other and said, 'Wait -- that actually sounds cool,' "...

Dinosaur-chewing mammals leave behind oldest known tooth marks

1000pa (June 17, 2010) — Paleontologists have discovered the oldest mammalian tooth marks yet on the bones of ancient animals, including several large dinosaurs.

They report their findings in a paper published online June 16 in the journal Paleontology.

Nicholas Longrich of Yale University and Michael J. Ryan of the Cleveland Museum of Natural History came across several of the bones while studying the collections of the University of...

New skeletons from the age of dinosaurs answer century-old questions about prehistoric reptile Typothorax

1000pa (May 31, 2010) — More than 100 years ago paleontologist E. D. Cope of "Dinosaur Wars" fame found a few fragmentary bones of a reptile in the deserts of New Mexico. He named the reptile Typothorax. A century later Typothorax, which belongs to a group of reptiles called aetosaurs, remained something of a mystery, known mainly from pieces of armor, a few limb bones, and some sections of tail.

Now, thanks to two remarkably complete...

New species of plant-eating dinosaur named for 'grinding mouth and wrinkle eye'

1000pa (June 1, 2010) — A team of paleontologists, including a University of Pennsylvania doctoral candidate, has described a new species of dinosaur based upon an incomplete skeleton found in western New Mexico. The new species, Jeyawati rugoculus, comes from rocks that preserve a swampy forest ecosystem that thrived near the shore of a vast inland sea 91 million years ago.

The dinosaur, whose name translates to mean "grinding-mouth,...

Prehistoric birds were poor flyers, research shows

1000pa (May 26, 2010) — The evolution of flight took longer than previously thought with the ancestors of modern birds "rubbish" at flying, if they flew at all, according to scientists.

Archaeopteryx, the theropod dinosaur believed to be the earliest bird, was discovered 150 years ago but debates about how flight evolved still persist. The two theories are that flight evolved in running bipeds through a series of short jumps or that Archaeop...

Demoting a dinosaur: New fossil material redefines Azendohsaurus as a peculiar early reptile

1000pa (May 18, 2010) — Azendohsaurus just shed its dinosaur affiliation. A careful new analysis of A. madagaskarensis -- this time based on the entire skull rather than on just teeth and jaws -- aligns this 230-million-year-old animal with a different and very early branch on the reptile evolutionary tree. Many aspects of Azendohsaurus are far more primitive than previously assumed, which in turn means that its plant-eating adaptations,...

Jurassic fast food was a key to giant dinosaurs

1000pa (May 11, 2010) — Why were the sauropod dinosaurs able to get so much larger than today's terrestrial animals? A research group led by the University of Bonn seems to have solved this puzzle. According to this research Jurassic fast food culture was a key to gigantism. The giant dinosaurs did not chew their food -- they just gulped it down. The results of the researchers' years of work are now being published in the journal Biological...

A shrunken giant: Island dino Magyarosaurus was a dwarf, after all

1000pa (May 3, 2010) — In 1895, the sister of an eccentric palaeontologist called Franz Baron Nopcsa discovered small dinosaur bones on their family estate in Transylvania. Nopcsa interpreted these as the remains of dwarfed animals that had once lived on an island. Among these finds were a number of bones belonging to a sauropod dinosaur which Nopcsa named Magyarosaurus dacus, after his native country.

A team of scientists led by Koen Stein...

Retracing the tracks of dinosaurs reveals ecosystem the size of a continent

1000pa (Apr. 22, 2010) — Researchers at McGill University are unlocking the mysteries of the little-known habits of dinosaurs in discovering that the entire western interior of North America was likely once populated by a single community of dinosaurs. According to a statistical analysis of the fossil record, dinosaurs were adept at coping with all sorts of environments, and not as restricted in their geographic ranges as previously...
