Enhydritherium terraenovae is an extinct marine otter endemic to North America that lived during the Miocene through Pliocene epochs from ~9.1–4.9 Ma. (AEO),Alroy, John, [https://paleobiodb.org/classic/displayCollResults?collection_no=19461 PaleoDB collection 19461: authorized by J. Alroy, entered by J. Alroy on August 5, 1996]. paleodb.org existing for approximately {{Mya|9.1-4.9|million years}}.
The ancestral lineage of Enhydritherium terraenova can be traced to Africa and Eurasia, but no clear route of migration can be determined according to Thompson et al.Feldhamer, George A., Thompson, Bruce C., Chapman.

Taxonomy
Enhydritherium terraenovae was named by Berta and Morgan in 1985{{cite journal|author=A. Berta and G. S. Morgan|year= 1985|title= A new sea otter (Carnivora: Mustelidae) from the late Miocene and early Pliocene (Hemphillian) of North America|journal= Journal of Paleontology |volume=59|issue=4|pages=809–819|jstor=1304931}} and is the genotype for this animal. Its type locality is the phosphate Palmetto Mine in Florida, which is in a Hemphillian marginal marine sandstone in the Upper Bone Valley Formation of Florida.
Fossil distribution

Fossil specimens were found in California (3 sites) and Florida (8 sites).
In 2017, part of a jawbone was found in the Juchipila Basin, Zacatecas.{{cite web |title=Rare Otter Fossil Found in the Mexican Desert |url=https://news.nationalgeographic.com/2017/06/otters-fossils-americas-mexico-paleontology-science/ |archive-url=https://web.archive.org/web/20170615043905/http://news.nationalgeographic.com/2017/06/otters-fossils-americas-mexico-paleontology-science/ |url-status=dead |archive-date=June 15, 2017 |accessdate=9 June 2018 |date=14 June 2017}} Located about 200 km from the modern Pacific coast and 600 from the Gulf of Mexico, the finding suggests the animal migrated across the continent using fresh water corridors in central Mexico.{{cite journal |last1=Tseng |first1=Z.
