Study first author Aaron Kufner, a geologist at the University of Wisconsin-Madison, and colleagues uncovered fossils of Buettnererpeton bakeri in a Wyoming fossil bed called Nobby Knob.
“This assemblage is a snapshot of a single population rather than an accumulation over time,” Kufner said in a statement. The discovery “more than doubles the number of known Buettnererpeton bakeri individuals.” Alongside the B. bakeri fossils, the team also found fossilized plants, bivalves and fossilized poop, called coprolites.
