Palaeovertebrata

The Oligocene deposits of the Ulantatal area in Inner Mongolia (China) contain among the richest mammalian faunas from Asia.To date, only some parts of the rodent faunas have been described.Here, we propose to review the rodent faunal lists for each site, including the description of a few new rodent specimens.We describe three additional rodent species: the Cylindrodontidae Anomoemys lohiculus, the Eomyidae Asianeomys sp., and the Dipodidae Litodonomys huangheensis.This study allows us to constrain the stratigraphic range of Anomoemys lohiculus, which ranged from the late Early Oligocene to the early Late Oligocene in this area.Asianeomys sp. and Litodonomys huangheensis are dated from the latest Oligocene.These Oligocene deposits consist now of more than 70 species of mammals if we include the fauna from Kekeamu.This latter corresponds to the basal part of the Ulantatal Formation and could be dated biochronologically from the earliest Oligocene.When compared to the faunas from the Valley of Lakes in Central Mongolia, the Ulantatal faunas present a great majority of rodents, and this difference can be partly explained by sampling and description biases regarding macro-mammals.This study also shows that variations existed between Inner and Central Mongolia, especially regarding the composition of the rodent paleocommunities.However, the assessment of their evolutionary history in this part of Asia with respect to the important climate and environment changes, require further precisions and more material than current data allow.

A cheek tooth recently unearthed in the Lopar Sandstone unit, of late Eocene age, in the northern part of Rab Island, Croatia, is one of the very few Eocene mammalian remains found in the Adriatic area.Thorough comparison of this tooth with those of Old-World Palaeogene mammalian orders suggests that it is a M3 belonging to an embrithopod afrothere.The specimen is referred to as Palaeoamasia sp.This genus was formerly known only in Eocene deposits of Anatolia but with close relatives in Romania among Palaeoamasiinae.The geographical distribution of this subfamily perfectly matches the recently-named Balkanatolian landmass, which experienced in-situ evolution of endemic mammals prior to the Grande Coupure event that occurred around the Eocene-Oligocene transition.This last event is characterised by massive Asian immigration in Western Europe and the supposed extinction of many endemic Central and Western European mammals, including Palaeoamasiinae.
