Bats place Kemmerer on world map

KEMMERER — Two of the oldest known bat fossils in the world were found in the Green River Formation near Kemmerer. The complete skeletons were found deep in what is called Fossil Lake in Fossil Basin. The formation’s site spans Wyoming, Utah and Colorado, in what was once an ancient lake and swamp during the era called the Eocene, around 50 million years ago.

John Collins, educational technician at Fossil Butte National Monument, said, “A third bat skeleton like the other two was found in 2022, which we purchased, and it will be on display at the Fossil Butte Museum before Memorial Day weekend.”
