}}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] References1. ^1 2 {{cite journal | author = Berta, A., Churchill, M., & Boessenecker, R.W. | year = 2018 | title = The Origin and Evolutionary Biology of Pinnipeds: Seals, Sea Lions, and Walruses | journal = Annual Review of Earth and Planetary Sciences | volume = 0| doi = 10.1146/annurev-earth-082517-010009}} 2. ^{{cite journal | author = Rybczynski, N., Dawson, M.R., & Tedford, R.H. | year = 2009 | title = A semi-aquatic Arctic mammalian carnivore from the Miocene epoch and origin of Pinnipedia | journal = Nature | volume = 458 | issue = 7241 | pages = 1021–24 | doi = 10.1038/nature07985 | pmid = 19396145}} 2 : Miocene pinnipeds|Transitional fossils |
