Buffalopterus is a prehistoric eurypterid from the Silurian-aged Bertie Formation of New York and Ontario. The genus contains one species, B. pustulosus. It is closely related to Strobilopterus , but differs primarily by having a bizarre, globular telson (which is otherwise sword-like or spine-like in other eurypterids), and in size, being estimated to be around 1 metre (3.3 ft), [1] although later study show size estimation of 30 centimetres (12 in).
