- n. A rodent species of the Khammouan region of Laos, scientific name Laonastes aenigmamus, first described in 2005
Last year, a new and unusual species of rodent was discovered in Laos, called Laonastes aenigmamus, or kha-nyou.
Photos of the skull and an 11 million year old fossil can be found in “Laonastes/Diatomys/kha-nyou/rat-squirrel”, on Pharyngula.
The second ‘late survivor’ brings us back to rodents: it’s the Laotian kha-nyou Laonastes aenigmamus, described last year as representing an entirely new hystricognath lineage, the Laonastidae (Jenkins et al. 2005).
