摘要
We report the first record of bite marks on an Upper Triassic dicynodontid bone from Poland. The bone comes from the Upper Triassic (Norian) Wozniki Limestone of Zawiercie, Krakow-Czestochowa Upland, southern Poland. The bone has several longitudinal bite marks on the anterior side of its shaft, as well as a row of small oval pits. The specimen bears, on its posterior side, evidence of additional damage parts of bone are missing in the proximal- and distal-end areas. The analysis of the longitudinal bite marks and pits indicates that more than one carnivore fed on the dicynodontid carcass. The different types of marks suggest that the specimen was scavenged.
