Sphaerium beckmani

Sphaerium beckmani is an extinct species of fossil freshwater pea clams from the Late Cretaceous deposits of North America. This species was first described by the American paleontologist Loris Shano Russell in 1976.[1][2] The specimens were collected by the American paleontologist Karl M. Waage from 1961 to 1962 from the Hell Creek Formation of eastern Montana. The locality is dated to the late Maastrichtian Age (around 66.0 to 72.1 million years ago).[3]

Sphaerium

Sphaerium is a genus of very small freshwater clams, aquatic bivalve molluscs in the family Sphaeriidae, known as the fingernail clams. The small clams in this genus are unusual in that many of them, such as Sphaerium corneum, can climb around underwater on aquatic plants, using their long and strong foot.
