Abstract
Seven avian remains from Mid-Holocene strata of the southeastern coast of Potter Peninsula (King George Island: Isla 25 de Mayo, South Shetland Islands, Antarctica) are reported. They were described and assigned to the brown skua Stercorarius antarcticus lonnbergi (Aves, Laridae), a living species currently breeding in the area. The presence of penguins in the same sequence is in agreement with the current dynamics of the coastal ecosystems of Antarctica. Nowadays, penguins and skuas frequent these same environments.
Kurzfassung
Aus dem mittleren Holozän der südöstlichen Küste der Potter-Halbinsel (King George Island: Isla 25 de Mayo, South Shetland Islands, Antarktis) werden sieben Rippen beschrieben, die dem Braunen Skua Stercorarius antarcticus lonnbergi (Aves, Laridae) zugeordnet werden. Diese Art kommt auch heute noch in der Region vor. Das gemeinsame Vorkommen von Pinguinen in der selben Fundschicht steht im Einklang mit der derzeitigen Dynamik der Ökosysteme der antarktischen Küsten. Heute leben auch noch Pinguine und Raubmöwen in derselben Umgebungen.
