A George Washington University expedition to the Gobi Desert of China has enabled researchers to solve the puzzle of how one group of dinosaurs came to look like birds independent of birds.
The research found that the theropod dinosaur Sinosauropteryx had simple bristles - precursors of feathers - in alternate orange and white rings down its tail, and that the early bird Confuciusornis had patches of white, black and orange-brown colouring.
Museum Victoria palaeobiologist Dr. Erich Fitzgerald has made groundbreaking discoveries into the origin of baleen whales, based on a 25-million-year-old fossil found near Torquay in Victoria, Australia.
A birdlike dinosaur related to Velociraptor took down prey with its fanglike teeth. Sinornithosaurus, a carnivorous Chinese dinosaur that likely feasted on other dinosaurs, was venomous, according to new analysis of its teeth and skull.
The recently unearthed theropod, Tawa hallae, solidifies the link between primitive carnivores and those that evolved into modern birds. The earliest stages of dinosaur evolution remain buried under eons of rock, but the discovery of this carnivore fossil in the U.S. Southwest promises to dispel some of the debate about how these beasts spread across the globe-and about the origins of the group that led to modern birds...
This past fall paleontologists unveiled two tyrannosaurs new to science that are shaking up long-standing ideas about everyone's favorite mega-predator. The finds are forcing researchers to reevaluate the origin of the tyrannosaur body plan and reconsider what they thought they knew about this well-studied group. "Our view of tyrannosaur evolution has changed dramatically," says doctoral student Stephen L. Brusatte of the American Museum of Natural History in New York City...
