Rootless teeth

Kretzoi (1956) analysed this fauna in detail, the first of the ""Allophaiomys faunas to be identified in Hungary. It is now known from the Osztramos series that this stage is an older stadium of that faunal wave which preceded the appearance of the modern voles which evolved towards the contemporary forms with rootless teeth Microtus, Pitymys). 

The animal assemblage is straightforwardly characterized by the last species of Mimomys (in 1965 Kretzoi showed that the valid name for this form is savini). Apart from this, the absolute predominance of ancestors of contemporary water voles (Arvicola), small voles with rootless teeth (Microtus and Pitymys) and locally steppe lemmings (Lagurus pannonicus), can be observed.
