Taxonomy
Lutra castiglionis was described in 2000, originally under a new genus, Cyrnolutra.[1] In 2006, it was transferred into the genus Lutra.[2] A possible ancestor of this species is Lutra simplicidens, known from mainland Europe.
Description
The Castiglione otter was probably very well adapted to a riverine aquatic way of life. Remains show a flattening of the sacrum, indicating it had a much stronger tail than most other otters, which would allow it to propel itself more efficiently in aquatic environments.[2]
Remains of the Castiglione otter are known from Castiglione Cave in Corsica. These fossils have been dated to the Mid Pleistocene, approximately 157,500 BP (+22,200/-17,300).
