Apatodemus degiulii n. gen. et sp. (Rodentia, Muridae), a hitherto undescribed endemite from the Terre Rosse of Gargano (Late Miocene, Southeastern I…
2016
The taxonomy of the murid that had been ascribed to the genus Apodemus from the late Miocene insular faunal assemblages of Gargano (Southeastern Italy) is revised. Morphological and odontometric analyses of important new dental characters were undertaken. Our investigations revealed substantial morphological differences from Apodemus. The rodent is therefore assigned to a new genus and species, Apatodemus degiulii. The new species is characterised by a combination of advanced and primitive characters: moderately brachyodont teeth, t7 present in all M1–2s, elongated and distally located t1 in M1, t1 often twinned in M1–2, and narrow labial cingulid in lower molars associated to a well-develo…
Mystemys giganteus n. gen. et sp.: an enigmatic and rare cricetid from the Terre Rosse M013 fissure filling (Gargano, Southeastern Italy).
2016
Mystemys giganteus is a new strongly endemic cricetid that occurs only in the recently discovered M013 Terre Rosse fissure filling of the Gargano area. This species was presented alongside the other taxa of the M013 fissure in a previous paper and it is here described in detail. Although the material includes only five molars, Mystemys is exceptional for its very large size (length of M1: 6.23 mm) and peculiar morphology. The molars are heavy built with bulged and robust cusps, tubercular crests, narrow valleys, very thick and crenulated enamel. The morphological features of Mystemys are very carefully described, with special focus on the evolutionary modifications induced by isolation. The…
