Fossil records of\n            <jats:italic>Enhydritherium<\/jats:italic>\n            are found in mostly marginal marine deposits in California and Florida; despite presence of very rich records of fossil terrestrial mammals in contemporaneous localities inland, no\n            <jats:italic>Enhydritherium<\/jats:italic>\n            fossils are hitherto known in interior North America. Here we report the first occurrence of\n            <jats:italic>Enhydritherium<\/jats:italic>\n            outside of Florida and California, in a land-locked terrestrial mammal fauna of the upper Miocene deposits of Juchipila Basin, Zacatecas State, Mexico. This new occurrence of\n            <jats:italic>Enhydritherium<\/jats:italic>\n            is at least 200 km from the modern Pacific coastline, and nearly 600 km from the Gulf of Mexico. Besides providing further evidence that\n            <jats:italic>Enhydritherium<\/jats:italic>\n            was not dependent on coastal marine environments as originally interpreted, this discovery leads us to propose a new east-to-west dispersal route between the Florida and California\n            <jats:italic>Enhydritherium<\/jats:italic>\n            populations through central Mexico. The proximity of the fossil locality to nearby populations of modern neotropical otters\n            <jats:italic>Lontra longicaudis<\/jats:italic>\n            suggests that trans-Mexican freshwater corridors for vertebrate species in riparian habitats may have persisted for a prolonged period of time, pre-dating the Great American Biotic Interchange.\n          <\/jats:p>","DOI":"10.1098\/rsbl.2017.0259","type":"journal-article","created":{"date-parts":[[2017,6,14]],"date-time":"2017-06-14T09:10:17Z","timestamp":1497431417000},"page":"20170259","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Discovery of the fossil otter\n            <i>Enhydritherium terraenovae<\/i>\n            (Carnivora, Mammalia) in Mexico reconciles a palaeozoogeographic mystery"],"prefix":"10.1098","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5335-4230","authenticated-orcid":false,"given":"Z.
