The Aral Formation  is a geologic formation  in Kazakhstan . It preserves fossils  dating back to the Neogene  period .[ 1] Glires  and fish, though cetaceans  and cryptobranchid  salamanders are also known.
Paleobiota 
The Aral Formation has yielded a rich variety of extinct mammals. Many of its mammal fauna consists of the clade Glires  with rodents being particularly numerous.[ 1]
