Homotrypa is an extinct genus of bryozoans from the Ordovician and Silurian periods, known from fossils found in the United States. Its colonies are branch-like and have small monticules made of groups of three or four larger zooecia slightly protruding out from the main surface of the colony. [2] [3] In cross section, the zooecia (tubes housing individual zooids) are erect in axis and gently curve toward the surface of the colony. [4]
