Newly discovered dinosaur likely father of Triceratops
Date:1/31/2011

longer nose and slightly bigger horns, Longrich said.

Instead, Longrich believes that Titanoceratops is the ancestor of both Triceratops and Torosaurus, and that the latter two split several millions years after Titanoceratops evolved. "This skeleton is exactly what you would expect their ancestor to look like," he said.

Titanoceratops was probably only around for about a million years, according to Longrich, while the triceratopsian family existed for a total of about 10 million years and roamed beyond the American southwest into other parts of the country and as far north as Canada.

In order to confirm the discovery beyond any trace of a doubt, Longrich hopes paleontologists will find other fossil skeletons that include intact frills, which would help confirm the differences between Titanoceratops and Pentaceratops.

"There have got to be more of them out there," Longrich said.
