Tseng Says Beardog Discovery Offers Clues to How Canines Evolved

Research co-authored by Jack Tseng, PhD, assistant professor of pathology and anatomical sciences, focuses on a fossilized carnivore jawbone that belonged to a beardog, an early, long-extinct relative of dogs, foxes and weasels that lived up to 40 million years ago.

“Our research pinpoints the southwestern U.S. as a key region in understanding the diversification and proliferation of this once successful group of predators prior to their extinction millions of years ago,” he said.
