2.5" Fossil Mosasaur (Platecarpus) Limb Bone - South Dakota
This is a 2.5" long Platecarpus limb bone collected from the Late Cretaceous (Campanian Stage) aged Pierre Shale of South Dakota, making it approximately 81 million years old.
There are a couple repaired cracks through the middle of the bone.

Platecarpus is an extinct aquatic lizard belonging to the mosasaur family. Fossils have been found in the United States as well as possible specimens in Belgium and Africa. It reached lengths of up to 14 feet long: half of that length was its tail alone. Platecarpus probably fed on fish, squid, and ammonites. Like other mosasaurs, it was initially thought to have swum in an eel-like fashion, though a recent study suggests that it swam more like modern sharks.
The genus attracted media attention in 2000, when a specimen unearthed in 1993 in South Dakota, United States, was interpreted as including a fossilized heart. There was much discussion over whether the remains were of a heart. Many scientists now doubt the identification of the object and the implications of such an identification.
