THE CORACOIDS IN FUNCTIONAL AND MORPHOLOGICAL STUDIES OF PENGUINS (AVES, SPHENISCIDAE) OF THE EOCENE OF ANTARCTICA ...
The partial articulated skeleton MLP 77-V-10-1 comes from the upper levels of La Meseta Formation (Seymour Island, Antarctica) at the southwestern slope of the plateau. These remains were found in the Submeseta Allomember, within the Anthropornis nordenskjoeldi Biozone, dated at 34.2 Ma using stront...
