A recently identified feathered dinosaur found deep in West Texas reinforces an emerging view that creatures like it were more diverse and widespread in North America than previously thought, according to a new study.

The species — a turkey-sized herbivore called Leptorhynchos gaddisi — belongs to a broader group of bird-like dinosaurs characterized by toothless beaks and long, slender claws, said researchers, who analyzed fossils found near Big Bend National Park at a site dating to about 75 million years ago.

Asteroid that Killed the Dinosaurs also Wiped out the ‘Obamadon’

The asteroid collision widely thought to have killed the dinosaurs also led to extreme devastation among snake and lizard species, according to new research — including the extinction of a newly identified lizard Yale and Harvard scientists have named Obamadon gracilis.

“The asteroid event is typically thought of as affecting the dinosaurs primarily,” said Nicholas R. Longrich, a postdoctoral associate with Yale’s Department of Geology and Geophysics and lead author of the study. “But it basically cut this broad swath across the entire ecosystem, taking out everything. Snakes and lizards were hit extremely hard.” (more…)

Torosaurus is Not Triceratops, Yale Researchers Say

A year-long study by Yale University paleontologists concludes that two related horned dinosaurs are different animals and not adult and juvenile versions of the same.

“We’re saying, ‘No, they’re different,’” said Nicholas R. Longrich, a postdoctoral fellow in Yale’s Department of Geology and Geophysics and the lead author of the study. “They’re separate animals.” (more…)
