Cranium of a Weddell Seal (Leptonychotes weddellii).
One of two seal skulls collected by H. R. 'Bob' Young in the vicinity of Little America on the Ross Ice Shelf during Richard E. Byrd's second Antarctic Expedition, stationed at Little America from January 1934 to February 1935. The expedition's biologist Alton Lindsey noted on 25 July 1934 that he started photographing seal skulls which had been cleaned by Young.
