Seorsumuscardinus
Seorsumuscardinus is a genus of fossil dormice from the early Miocene of Europe. It is known from zone MN 4 in Oberdorf, Austria; Karydia, Greece; and Tägernaustrasse-Jona, Switzerland. It may be related to Muscardinus, the genus of the living hazel dormouse, which appears at about the same time.
About Seorsumuscardinus in brief
Seorsumuscardinus is a genus of fossil dormice from the early Miocene of Europe. It is known from zone MN 4 in Oberdorf, Austria; Karydia, Greece; and Tägernaustrasse-Jona, Switzerland. Only the cheek teeth are known; these include the fourth premolar and three molars. The teeth are all characterized by long transverse crests coupled with shorter ones. It may be related to Muscardinus, the genus of the living hazel dormouse, which appears at about the same time, and the older Glirudinus. All three are part of the dormouse family, which includes many extinct forms dating back to the early Eocene. The generic name SeorsumUScardinus combines the Latin seorsum, which means “different”, with the specific name alpinus, which refers to the occurrence of S.
alpinus close to the Alps. The species S. bolligeri was placed in a separate genus, Heissigia, when it was first described in 2007, but it was reclassified as a second species in 2009. The two species are known from isolated teeth, which show that they were medium-sized dormice with flat teeth. The fourth upper premolar has four main, transversely placed, posterlopholophus, and a small posterolophi, centrally placed in the upper molar. The upper jaws are flat and have a flat occusal surface, with a small, protolophlophus-like surface.
