Ceratiocaris is a genus of paleozoic phyllocarid crustaceans. They are typified by eight short thoracic segments, seven longer abdominal somites and an elongated pretelson somite. Their carapace is slightly oval shaped; they have many ridges parallel to the ventral margin and possess a horn at the anterior end.[1] They are well known from the Silurian Eramosa formation of Ontario, Canada.[2][3]
The following species are included:
- Ceratiocaris macroura Collette & Rudkin, 2010
- Ceratiocaris monroei Salter in Murchison, 1859
- Ceratiocaris murchisoni Jones & Woodward, 1888
- Ceratiocaris papilio Salter in Murchison, 1859
- Ceratiocaris pusilla Matthew, 1889
- Ceratiocaris stygia Salter in Murchison, 1859
- Ceratiocaris solenoides M'Coy, 1849
