Scientists have unveiled fossils of one of the earliest dinosaurs ever discovered -- a petite, nimble carnivore from the late Triassic period some 230 million years ago. Dubbed Eodromaeus, or "dawn runner", the never-before seen species was a small, two-legged creature that may have been among the first dinosaurs to roam the Earth, making them likely ancestors of the famous Tyrannosaurus rex. The scientists reconstructed the dinosaur from a nearly complete set of bones found in Ischigualasto,...

BoarCroc, RatCroc, DogCroc, DuckCroc and PancakeCroc A suite of five ancient crocs, including one with teeth like boar tusks and another with a snout like a duck's bill, have been discovered in the Sahara by National Geographic Explorer-in-Residence Paul Sereno. The five fossil crocs, three of them newly named species, are remains of a bizarre world of crocs that inhabited the southern land mass known as Gondwana some 100 million years ago. Sereno, a professor at the University of Chicago,...

The Tyrannosaurus Rex is characterized by its big head, packed with sharp teeth, and tiny arms. However, a new ancestor has been dug up in China that was only 10 feet tall and 150 pounds, aptly nicknamed "Raptorex." Though the mini Raptorex is almost 100 times smaller than the T. rex, it is practically identical in structure, even sporting the same little arms and all the fortunate traits that made it such a successful predator, said lead author Paul Sereno from the University of Chicago and...

University of Chicago paleontologist Paul Sereno says Psittacosaurus gobiensis is the first dinosaur species that ate mainly nuts. Sereno, who discovered fossils of the 3-foot-long dinosaur in Inner Mongolia in 2001, said the skull features of the dinosaur that lived 110 million years ago are reminiscent of a parrot, the Chicago Sun-Times said Thursday. The parallels in the skull to that in parrots, the descendants of dinosaurs most famous for their nut-cracking habits, is remarkable, said...

Plants or meat: That's about all that fossils ever tell paleontologists about a dinosaur's diet. But the skull characteristics of a new species of parrot-beaked dinosaur and its associated gizzard stones indicate that the animal fed on nuts and/or seeds. These characteristics present the first solid evidence of nut-eating in any dinosaur."The parallels in the skull to that in parrots, the descendants of dinosaurs most famous for their nut-cracking habits, is remarkable," said Paul Sereno, a...

U.S. paleontologists say 25 teenage dinosaurs who died trapped in mud are giving scientists new information on ancient history in Asia's Gobi Desert. The dinos died together 90 million years ago after running into a sinkhole of mud in western Inner Mongolia, said Paul Sereno, a University of Chicago paleontologist who led the expedition. The skeletons of the two-legged, plant-eating, Sinornithomimus dongi were so perfectly preserved they contained the remains of the dinos' last meal, Sereno...

A herd of young birdlike dinosaurs met their death on the muddy margins of a lake some 90 million years ago, according to a team of Chinese and American paleontologists that excavated the site in the Gobi Desert in western Inner Mongolia. The sudden death of the herd in a mud trap provides a rare snapshot of social behavior. Composed entirely of juveniles of a single species of ornithomimid dinosaur (Sinornithomimus dongi), the herd suggests that immature individuals were left to fend for...

Paleontologists have discovered the remains of a large meat-eating dinosaur with a breathing apparatus much like a modern bird, fortifying the link between birds and dinosaurs and helping to explain the evolution of birds' unique system of breathing. The scientists said the specimen, pulled from 85-million-year-old rock along the banks of Rio Colorado in Argentina's Mendoza Province, was a 33-foot-long (10 meter), two-legged predator that weighed as much as an elephant and likely had...

By John Noble Wilford New York Times News Service When Paul C. Sereno went hunting dinosaur bones in the Sahara, his career took a sharp turn from paleontology to archaeology. The expedition found what has proved to be the largest known graveyard of Stone Age people who lived there when the desert was green. The first traces of pottery, stone tools and human skeletons were discovered eight years ago at a site in the southern Sahara in Niger. After preliminary research, Sereno, a...
