Reptilia

Taxonomy

Palaeospheniscus bergi was named by Moreno and Mercerat (1891). Its type specimen is Museo de La Plata, a set of limb elements (humerus, radius, tarsometatarsus), and it is a 3D body fossil. Its type locality is Cerro del Castillo, Trelew, which is in an Aquitanian/Burdigalian shallow subtidal sandstone in the Gaiman Formation of Argentina.

It was recombined as Paraspheniscus bergi by Ameghino (1905), Lambrecht (1933), Simpson (1946), Brodkorb (1963).
