Ja. Todd et al., A BIOIMMURED CTENOSTOME BRYOZOAN FROM THE EARLY CRETACEOUS OF THE CRIMEA AND THE NEW GENUS SIMPLICIDIUM, Geobios, 30(2), 1997, pp. 205-213
A well-preserved soft-bodied arachnidiid ctenostome from the Berriasia
n of the Crimea (Ukraine) is the first example of a bioimmured bryozoa
n from eastern Europe. The specimen has additional importance as one o
f very few bryozoans recorded from the Berriasian worldwide. It is ide
ntified as Arachnidium brandesi, previously known from the German Barr
emian, and referred to the new genus Simplicidium [type species Cellar
ia smithii (PHILLIPS)].
