BRYOZOA 1: SCREEN-LIKE OR FENESTRATE FORMS
Phylum Bryozoa Fenestrellina
Fenestrellina is one of the screen-like forms called the fenestrate bryozoans. The easily visible holes are not the chambers that the animals lived in. The animals lived in tiny chambers called zooecia in the walls of the screen (tiny circles in picture). Don’t be fooled by the similar brachiopod molds with little holes where the spines emerged.
