End-Permian Mass Extinction Paved Way For Modern Mammals
2013-08-28 16:19:55

Peter Suciu for redOrbit.com - Your Universe Online Mass extinction certainly sounds like it would be the end of the line, and perhaps even evokes images of the end of the world.

"Apparently one size doesn't fit all when it comes to dinosaur feeding styles," said Ohio University paleontologist Eric Snively. "Many people think of Allosaurus...

Othniel Charles Marsh (October 29, 1831 – March 18, 1899) was an American paleontologist, specializing primarily in vertebrates. He is highly renowned as one of the most prominent scientists of his time, having discovered and described dozens of new species. Marsh is also credited with developing what is currently the most widely accepted theory of the origin of birds. Marsh was born in Lockport, New York, to a family of moderate means.
