Ultra-low oxygen could have triggered die-offs, spurred bird breathing system
...at high altitude. Now, a University of Washington paleontologist theorizes that low oxygen and repeated short but substantial temperature increases because of greenhouse warming sparked two major mass-extinction events, one of which eradicated 90 percent of all species on Earth. In addition, Peter Ward, a UW prof...Scientists believe ancient arachnids may have spun silk like modern spiders
... around for a long time, said Conrad Labandeira, a paleontologist at the Smithsonian Institution in Washington, D.C., and an adjunct professor of geological sciences at Ohio State. Trigonotarbids were predators, so its possible that they used silk to trap prey. Or they could have lined burrows with it, as a means o...Dinosaur symposium at the Smithsonian Institution
... until 4:45 p.m. On Dec. 14, world-famous dinosaur paleontologist Jack Horner will kick off the second day of the symposium with the keynote speech at noon. Horner is the curator of paleontology at the Museum of the Rockies in Bozeman, MT. He is also a senior scholar at the Smithsonian Institution. His talk, "D...Dinosaur fossil record compiled, analyzed
...cused on the evolution of dinosaurs. It is to the paleontologist what Beckett's Baseball Card Price guide is to the baseball card collector, and more - Heathcote's analysis provides information on the relationships between classes and groups, whereas the Beckett guide draws no lineages for players, for instance.

... discovered by a team led by University of Chicago paleontologist Paul Sereno. The find provides fresh information about how and when the ancient southern continents of Africa, South America and India separated. The new species, which is 95 million years old, and a second new meat-eating species Sereno found on a...Computer imaging of Archeopteryx skull suggests this dinosaur-bird link could fly
