Cephalotropis is a genus of baleen whale belonging to the extinct family Cetotheriidae. Its type species is Cephalotropis coronatus.
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]
