Calomyscus Urartensis
The Urar mouse-like hamster or Azerbaijani mouse-like hamster (''Calomyscus urartensis'') is a medium-sized mouse-like hamster from Nakhichevan, Azerbaijan and northwestern Azarbaijan Province, Iran. It is among the better studied representatives of this poorly known genus. The initial species description was based on a unique chromosome number (2n=32; FNa=42) called a karyotype. The species status has been confirmed with other chromosomal studies and morphometric studies. The species description by Vorontsov ''et al.''Vorontsov, N. N., I. Kartavtseva, and E. G.

They are found in rocky outcrops and semi-mountainous areas in desert regions. The mouse-like hamsters are not true hamsters, but represent an early split from the rest of the Muroidea, mouse-like rodents. They were once thought to be hamsters based on the shape of their molars, but they lack the cheek pouches, flank glands and short tails of the true hamsters. The closest relatives of the mouse-like hamsters may be the extinct Cricetodontidae. Because of their seemingly early break from the rest of the mouse-like rodents, mouse-like hamsters have been placed in a family of their own, Calomyscidae, and have been referred to as living fossils. All members of the genus were once considered part of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
