World's first caecilian fossil from Triassic Era found in Petrified Forest NP

A team of paleontologists from Virginia Tech and the U.S. Petrified Forest National Park, among others, have discovered the first “unmistakable” Triassic-era caecilian fossil — the oldest-known caecilian fossils — thus extending the record of this small, burrowing mammal by roughly 35 million years. The find also fills a gap of at least 87 million years in the known historical fossil record of the amphibian-like creature.
