Ząb morskiego krokodylomorfa z jury Wyżyny Krakowsko-Częstochowskiej

An incomplete tooth-crown showing the features characteristic of marine crocodylomorphs of the family Metriorhynchidae has been found in glauconitic marls from the uppermost Callovian/lowermost Oxfordian of Ogrodzieniec, situated in the southern part of the Cracow-Czestochowa Upland. The precise taxonomic identification is not possible, but to date only the genus Metriorhynchus has been known from the Callovian. This is the first evidence of Metriorhynchidae in the Cracow-Czestochowa Upland (Polish Jura Chain).
