Bassariscus lycopotamicus

Bassariscus lycopotamicus is an extinct small carnivoran that the Paleobiology Database places in the genus of the living ringtail and cacomistle, in the raccoon family Procyonidae. Edward Cope first described it in 1879 from a fragment of lower jaw, naming it as an otter-like form; the original specimen has since been lost and is known only from a published figure. The database dates the species from the Burdigalian to the Serravallian stage, about sixteen to twelve and a half million years ago, and records two occurrences in Grant County, Oregon. It treats the animal as terrestrial and actively mobile, with an arboreal habit and a diet of fruit and meat, but those habits are borrowed from the genus and the family and are not observed in this species.
