Vertebrate remains, mostly nothosaurid vertebrae and long bones, archosaur partially preserved long bones and teeth (probably rauisuchid remains), fish teeth and scales, are described from the Lower Keuper Miedary Beds (Ladinian, Middle Triassic) of Miedary, Silesia, SW Poland. The analyzed vertebrate fossils were collected from three lithologically different types of deposits. The first assemblage, which contains nothosaurid and fish remains, occurs in yellowish dolomites, where poorly preseved invertebrate macrofossils were also found (marine bivalves and brachiopods). In grey-yellowish, sometimes greenish or red clays, rare isolated bones and teeth of large archosaur were found. In sandstone intercalations partially preserved and highly disarticulated fish fossils were identified. In all assemblages osteological remains are generally very well preserved. This new interesting vertebrate bones association from the upper part of the Middle Triassic marginal-marine strata of Poland has been correlated with age-equivalents from other regions of Europe.
