Description edit
Cephalotropis is diagnosed by the following features: a long sagittal crest, a more anteriorly produced angle of the supraoccipital angle, among other features.[1] There is insufficient information to determine how big Cephalotropis was, but it probably grew to about 16–20 feet long.
Taxonomy edit
Cephalotropis coronatus was originally described from the Late Miocene (Tortonian) St. Mary's Formation of St. Mary's Formation, Maryland, based on the holotype USNM 9352.[2] A second species of the genus, C. nectus, was named for a specimen from a Tortonian-aged formation in Portugal,[3] but is now considered a junior synonym of C. coronatus.[4]
