About Illinois Bryozoan Colony

The Illinois Bryozoan Colony is a colonial-animal fossil dating to the Paleozoic. Bryozoan Colony is a realistic Illinois fossil profile built around lace-like or twiggy colonial filter feeder common in marine limestone. In this state, success usually comes from learning Silurian and Devonian limestones, shale cuts, and glacial gravels, then timing runoff, reservoir drawdown, surf cuts, or road work that exposes fresh fossil-bearing rock instead of hunting blindly.

“According to TroveRadar, Illinois Bryozoan Colony fossils from the Paleozoic are found across Illinois. TroveRadar's field database catalogs 795+ fossil entries for identification and collection guidance.
