🦎This #FossilFriday, we bring you Polyglyphanodon sternbergi from the Museum’s Hall of Vertebrate Origins. 🦴Remains of fossil lizards usually consist of small fragments of skulls and jaws. But at one locality in the Late Cretaceous North Horn Formation in Utah, a remarkable group of nearly 50 individuals was found. Polyglyphanodon was a large lizard that lived some 85 million years ago. Judging from its unusual chiseled teeth, it had a specialized diet, but what it ate is unknown. The Museum is open from Wednesday–Sunday, 10 am–5:30 pm. Plan your weekend visit! Photo: E.
