The first specimen of Archelon (YPM 3000) was collected from the Pierre Shale of South Dakota in 1895.
The largest Archelon fossil, found in the Pierre Shale of South Dakota in the 1970s, measures more than 4 m (13 ft) long, and about 4.9 m (16 ft) wide from flipper to flipper. It was a marine turtle, whose closest living relative in the present day is the leatherback sea turtle.
Archelon’s fossils date to around 75-65 million years ago in the Late Cretaceous period, when a shallow sea covered most of central North America.
