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]
