Phylum Bryozoa

Abstract/Description: Ordovician. Brookville Formation. The Bryozoa (moss animals) are a geologically important group of small animals; some that suberficially resemble corals. All bryozoans are colonial and most are marine. Bryozoans are most abundant in temperate-tropical waters that are not too turbid. They require a hard or firm substrate to attach to, and clear agitated water from which they obtain their suspended food.
