Biology:Myocastor
Myocastor (from Ancient Greek μῦς (mûs) 'rat, mouse', and κάστωρ (kástōr) 'beaver')[1][2] is a genus of rodent that contains the living nutria (or coypu), as well as several fossil species.
Taxonomy
Due to similar cranial morphology, the nutria was once considered a close relative of the Caribbean hutias and placed together with them in the family Capromyidae.[3] Later, it was more accepted to place it in its own family, the Myocastoridae.[4] Recent molecular studies place them in the family Echimyidae, in the tribe Myocastorini.[5][6][7]
Fossil record
Kerber et al. (2013) recognize the following species as valid:[8]
- Myocastor columnaris (Middle Pleistocene)
- Myocastor obesus (Late Miocene)
- Myocastor paranensis (Late Miocene)
Other species described but no longer considered valid include Myocastor minor, Myocastor perditus, and Myocastor priscus.
