Caprovesposus

Caprovesposus is an extinct, prehistoric surgeonfish that inhabited the Paratethys Sea during the Oligocene. It is known from a single species, C. parvus, from what is now the North Caucasus, Russia. Potential specimens are known from the Miocene of Egypt, but these are poorly preserved and this attribution is uncertain.

Known from very small fossils (up to 3 centimeters in length), it was initially described as a boarfish, but later studies found it to represent a pelagic larval (acronurus) or juvenile stage of a surgeonfish. The adult form is, as yet, unknown.
