Semantoridae

Semantoridae is an extinct family of stem-pinnipeds with fossils found in France, Kazakhstan, and Canada, dating back to various points in time in the Miocene epoch.[1][2] Based on their overall anatomy semantorids were not marine specialists, as their elongated bodies, a long tail and robust limbs suggest they were freshwater animals not unlike otters.[1] Indeed, at least some taxa such as Semantor and Potamotherium were initially classified as mustelids closely related to otters.[1]
