Stenopterygius
Genus of reptiles (fossil)
Stenopterygius is an extinct genus of thunnosaur ichthyosaur known from Europe (England, France, Germany, Luxembourg and Switzerland). It was a medium-sized ichthyosaur, with multiple well-preserved specimens, including one which preserved evidence of countershading (similar to most sharks), blubber and a raised, homeothermic metabolism. as well as a female specimen that died in childbirth that showed that the genus preferred tail-first births similar to modern cetaceans.
