Huellas de mordeduras en un caparazón de quelonio del Kimmeridgiense (Jurásico Superior) del norte de Alemania

Abstract

From the original sample Upper Jurassic turtles described by oertel (1914), one delivered specimen from the Langenberg near Oker (Goslar), Lower Saxony, Northwestern Germany is described, which are still today in the collection of the Geomuseum Göttingen. That is reproduced photographically for the first time. That shell fragment of Plesiochelys etalloni shows clear bite marks by two predatory vertebrates. In contrast to the round bite marks of the crocodile (A-B) in the center of present scars, and the irregular sharp scratches of sharks, the present irregular and narrower. These correspond to machimosaurid and a velociraptorine dromaeosaurid (C-H) rather than the polluters.
