Abstract

Morphology and astogeny of a Jurassic bryozoan species Terebellaria ramosissima Lamouroux, 1821 (Stenolaemata) which are abundant in the Middle Callovian of Moscow and the Moscow region, are studied using traditional microscopy combined with X-ray microtomography. The endozone of helical colonies is formed by kenozoids (intrazooids), which developed in an ascending spiral around a virtual axis; the exozone is formed by reversed autozooids developed in a downward spiral and formed encrusting multilayered belts. Their inner walls are penetrated with connecting pores of a transverse-row arrangement. No pseudopores are found in the outer walls. Complex astogeny is unique to this Jurassic bryozoan species.
