The first skull of Anthropornis grandis (Aves, Sphenisciformes) associated with postcranial elements
Associated penguin remains found in Bartonian levels of the Submeseta Formation (Seymour Island, Antarctica), including cranium and mandible, both partial tarsometatarsi, and some other fragmentary bones, are analyzed here. This specimen preserves the first cranium reliably assigned to the giant for...

description |
Associated penguin remains found in Bartonian levels of the Submeseta Formation (Seymour Island, Antarctica), including cranium and mandible, both partial tarsometatarsi, and some other fragmentary bones, are analyzed here. This specimen preserves the first cranium reliably assigned to the giant form Anthropornis grandis, and constitutes the first opportunity to taxonomically assign a cranial material to any of the Antarctic penguin species. A discussion of the diet preferences and feeding mechanisms of A. grandis is supported here by three-dimensional paleoneurological and cranial-jaw muscular reconstructions. We propose that A. grandis was a penguin with a voluminous musculature strongly attached to the neck and skull, adapted to chase and hunt fish during diving. Les restes associés aux manchots trouvés dans les niveaux de Bartonien dans la formation de Submeseta (île Seymour, Antarctique), y compris le crâne et la mandibule, des tarsométatarses partiels et quelques autres os fragmentaires, sont analysés ici. Ce spécimen conserve le premier crâne attribué de manière fiable à la forme géante Anthropornis grandis et constitue la première occasion d’affecter de manière taxonomique un matériau crânien à l’une des espèces de manchots antarctiques. Une discussion sur les préférences alimentaires et les mécanismes d’alimentation d'A. grandis est étayée ici par des reconstructions paléoneurologiques en trois dimensions et une reconstruction musculaire crâne–mâchoire. Nous proposons qu’A. grandis était un manchot à la musculature volumineuse, fortement attachée au cou et au crâne, adapté à la poursuite et à la chasse des poissons en plongée.
