A great 385 million year old addition to your fossil collection!
Bryozoans are sea animals that live in colonial structures. Because these structures are usually composed of secreted calcite, the Bryozoans commonly form fossils. Bryozoans show up in the fossil record in the early part of the Ordovician Period, about 485 million years ago. They are sometimes confused with corals, but are more complex organisms than corals.
If you look closely, you may notice small pits in the surface. Each pit was once home to a single zooid. They were attached to the structure and survived by feeding on microscopic organisms floating by.
