Bryozoan (Stenolaemata) records from the upper Callovian (Middle Jurassic) of the Moscow region

详细

Encrusting bryozoans (Stenolaemata, Tubuliporida) discovered from upper Callovian deposits (Middle Jurassic) near the town of Kolomna in the Moscow region are described. They belong to two new species: Microeciella kolomnensis sp. nov. and Diplosolen akatjevense sp. nov. These bryozoans encrust a fragment of the large shell of cephalopod mollusk (ammonite), which is an unusual substrate not only for bryozoans but also for the other encrusting organisms.
