Additional Pelagornithidae remains from Seymour Island, Antarctica
Two incomplete mandibles are assigned to Pelagornithidae given the presence of a well marked neurovascular furrow and the unique bony projections, or “pseudo-teeth”, along the crista tomialis. Specimens IAA-Pv 175 from Ypresian levels of La Meseta Alloformation (Cucullaea I Allomember), and IAA-Pv 8...
