redOrbit Staff & Wire Reports - Your Universe Online A number of Psittacosaurus fossils, once believed to represent three different species, actually all belong to a single dinosaur species, researchers from the University of Pennsylvania claim in a new study. Differences in the specimens had led scientists to label them as separate species, senior author Peter Dodson, a professor of anatomy in Penn's School of Veterinary Medicine and professor of paleontology in the School of Arts...

An international team including University of Pennsylvania paleontologists is unearthing the appearance of ancient animals by using the world's most powerful X-rays. New research shows how trace metals in fossils can be used to determine the pigmentation patterns of creatures dead for more than a hundred million years. The research was conducted by an international team working with Phillip Manning, an adjunct professor in the School of Arts and Sciences' Department of Earth and Environmental...

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, wrinkle-eye," was most likely an herbivore that ate the ferns and conifer trees...

WASHINGTON (AP) -- Good news for dinosaur fans: There are probably a lot more of them waiting to be discovered. At least, their fossils are. Peter Dodson of the University of Pennsylvania and Steve Wang of Swarthmore College estimate that 71 percent of all dinosaur genera -- groups of dinosaur species -- have yet to be discovered. "It's a safe bet that a child born today could expect a very fruitful career in dinosaur paleontology," Dodson said in a statement. The estimate appears in...

Originally, this dinosaur had seven known subspecies. All of them were studied extensively in 1975 by Peter Dodson, who studied the differences between the skulls and the crests of different types of dinosaurs. He found that differences in size and shape of the seven named subspecies were actually different age groups of the same species. Today, only one species is known (C. casuarius). Corythosaurus was about 35 feet in length from nose to tail and weighed about 4 tons. Like all...

Avaceratops, or the "Ava horned face", lived during the Late Cretaceous Period, and is a genus of small ceratopsian dinosaur. They were found in what is now the Northwestern United States. It was first discovered in the Judith River Formation of Montana in 1981. The fossils were found scattered along the remains of a prehistoric stream bed. It is believed that the specimen was buried in the sandbar after its body was washed downstream by a current. Eddie Cole made the original find and the...
