Abstract

Simplomys, a dormouse with a simple dental morphology compared to other glirids, shows a continuous evolution in Spain during the end of the Ramblian and up to the middle Aragonian, the stratigraphic frame considered in this work. In contrast, the record of the genus in Central Europe is reduced to a few localities spanning from the early to the middle Miocene. We review the record from the Burdigalian to Langhian equivalent to the deposition of the uppermost Upper Marine Molasse (OMM) to the lower part of the Upper Freshwater Molasse (OSM) and conclude the occurrence of three distinct species. The youngest species, Simplomys simplicidens, is recognised in Schonenberg (Germany, MN5) and Courrendlin-Sole (Switzerland;MN4). Material from a fissure filling near Glovelier (Switzerland, MN4) supplied the new species, Simplomys hugi, whereas the localities Petersbuch 2 and Erkersthofen 2 (both fissure fillings from Germany, MN4) contain species closely related to it. Finally, and pending further advances in the taxonomy of the Iberian Simplomys, the oldest population from the fissure filling of Schnaitheim (Germany;MN3) remains in open nomenclature (Simplomys sp.). The genus Simplomys has not been recorded eastwards from the Swabian and Franconian Jura Plateaus from Germany and its youngest occurrence in Schonenberg is correlated to the South German local scale OSM C+D, at around 15.5 Ma.
