Phylum Bryozoa Fenestrellina

Fenestrate Bryozoan

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).

At the fossil site, don’t be fooled by the molds of brachiopods, which have little holes where spines once emerged, making them look like bryozoans.
