| Abstract: | Two new species of encrusting bryozoans (Stenolaemata, Tubuliporida) from the Middle Callovian (Middle Jurassic) deposits of the Bryansk Region, Oncousoecia guzhovi sp. nov. and Microeciella fokinensis sp. nov., are described. Their intracolonial variability, which is due to differences in astogenetic stages and to external factors, is discussed. |
