Dinosaurs

Eighty million years ago, tyrannosaurs were the top predators in Asia and North America.

And scientists say a newly discovered dinosaur from Uzbekistan helps to explain their rise.

In a paper published Monday in the Proceedings of the National Academy of Sciences, researchers said they have found a specimen from a 20 million-year gap in fossil records — between the small-bodied "marginal hunters" and the "apex predators" the tyrannosaurid group would become. This group includes Tyrannosaurus rex, Albertosaurus and Tarbosaurus.

  Washington State has its first dinosaur.

Researchers at the Burke Museum say they excavated a weathered, 80 million year old thighbone from a beach on Sucia Island in the San Juans. It is the first verified dinosaur fossil ever found in Washington.

A researcher at the University of Washington says he’s identified the oldest dinosaur ever – pushing back the emergence of dinosaurs by millions of years.

The fossilized bones were discovered back in the 1930s, in Tanzania, in a major find that included a vast collection of specimens. They were gathering dust at the Natural History Museum, London, until the scientist who had custody passed away. 

Longest unpublished dissertation ever?

MISSOULA, Mont. — The folks at Hi-Noon Petroleum in Montana have a new way to turn a dinosaur into gasoline.

They're offering a $250 gas card for information leading to the safe return of Dino, a 12-foot-long fiberglass Sinclair dinosaur that disappeared June 21 from the Crossroads Travel Center west of Missoula.
