Tsaganomyidae Explained

The Tsaganomyidae are an extinct family of rodents from Asia. It contains three genera.[1] Tsaganomyids are generally considered to be related to the Hystricognathi (porcupines and relatives).[2] Members of Tsaganomyidae were fossorial (digging) rodents that probably used their incisor teeth to dig like some living mole rats.[3]

Characteristics

Tsaganomyids had a protrogomorphous zygomasseteric system, a hystricognathous lower jaw, and multiserial enamel in their incisor teeth.[3]
