Stensiopelta is an extinct genus of armored jawless fish (Class Osteostraci) that lived during the Devonian Period. It has been assigned to the unranked group, Cephalaspidomorphi. It’s called a cephalaspid for short.

Usually the only part of a cephalaspid that is found is the head shield (or just parts of it) but here we have the whole fish! It’s a must-have for the serious fish collector.
