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.{{Cite journal|last=Loeblich|first=Alfred R.|date=July 1942|title=Bryozoa from the Ordovician Bromide Formation, Oklahoma|journal=Journal of Paleontology|volume=16|issue=4|pages=420–422}}{{Cite book|last1=Nickles |first1=John M|last2=Bassler |first2=Ray Smith|title=A synopsis of American fossil Bryozoa, including bibliography and synonymy|date=1900|publisher=Department of the Interior, United States Geological Survey|url=https://permanent.fdlp.gov/gpo58750/report.pdf|page=29}} In cross section, the zooecia (tubes housing individual zooids) are erect in axis and gently curve toward the surface of the colony.{{cite journal |last1=Bork |first1=Kennard B. |last2=Perry |first2=T.G. |title=Bryozoa (Ectoprocta) of Champlainian Age (Middle Ordovician) from Northwestern Illinois and Adjacent Parts of Iowa and Wisconsin.
