Macropoma

Macropoma is an extinct genus of coelacanth in the class Sarcopterygii. Fossils of Macropoma have been found in both England and Czech Republic, dating to the mid-Cretaceous. Recorded fossils have bodies under two feet in length. A modern coelacanth measures five or more, but in other respects the two genera are remarkably similar, and share the same body plan with a three-lobed tail and stalked fins.
Macropoma grew to a length of 19-23 inches and would have preyed upon smaller aquatic species.
