文摘

The internal structure of bryozoans of the genera Pachydermopora Gordon, 2002 and Beisselina Canu, 1913 (Cheilostomida: Ascophora) from a Campanian erratic block near the town of Grodno (Belarus) is for the first time investigated in detail using X-ray micro-CT. The data obtained from these investigations allow erection of two new species, i.e., Pachydermopora grodnoensis sp. nov. and Beisselina skyscanica sp. nov. The examination of the micro-CT slices reveals the most significant characters allowing more accurate identification of the species of these genera.
