Two bonebeds with numerous remains of Dactylosaurus (Reptilia, Sauropterygia) and ganoid fishes were discovered in the uppermost Rot (Lower Triassic, Olenekian), exposed in the vicinity of Gogolin (Opole Silesia, SPoland). The lower bonebed, which is up to 5 cm thick, is built of several laminae. On the top of the individual laminae, vertebrae, teeth, long and flat bones of reptiles, as well as fish scales, teeth and a skull fragment have been found. The upper bonebed, which is up to 2 cm thick, contains smaller bones of reptiles (mainly vertebrae and long bones), and also fish scales. The bonebeds are particularly abundant in vertebrate remains: 1 m2 usually contains several dozens of them. All remains are disarticulated. Gogolin is probably the third or second site with Rot deposits where remains ofDactylosaurus have been found, and the richest one.
