Long-delayed analysis of dinosaur bones found in Big Bend NP reveal new, more primitive species

A new, more primitive species of dinosaur was discovered at Big Bend National Park this week.

The fossil of the new specials, Aquilarhinus palimentus, was unearthed in the 1980s by Texas Tech University Professor Tom Lehman. But because the bones were so "badly weathered and stuck together," it was not until recently that researchers could analyze it, according to a release from the park.
