The inhibitory cascade (IC) represents a developmental model that explains the evolution of molar relative sizes, originally described in rodents but later validated in several mammalian groups. The IC comprises signalling molecules produced by the first molar buds that inhibit the development of…

The locality Mikhailovka-5 is situated in the northern part of the Mikhailovka quarry in the northwest of the Kursk Oblast in central Russia. A rich mollusk fauna was collected along with small mammal remains from this lacustrine deposit located between Likhvinian (= Holsteinian) fossil soils and…

The Middle Pleistocene site Bilzingsleben II is well-known for its wealth of vertebrate and archaeological remains. Of particular importance is the record of Homo erectus bilzingslebenensis. Most palaeontologists consider the find horizon as a primary vertebrate deposit formed during human…

Water voles are important key fossils of the Quaternary. Given their wide distribution, regional differences were expected to exist in different areas. Early hints on possible independent evolutionary trends of water voles in Italy came from palaeontology and specifically from the comparison of…

The original fossil record of Allosorex stenodus Fejfar, 1966 from Ivanovce (late Ruscinian, MN 15b) is redescribed and supplemented by the description of so far unpublished fossil remains, including upper dentition (P4 and M3) and a humerus fragment as well as the enamel microstructure…

The vertebrate locality of Dorkovo yielded a rich mammalian assemblage of which some large mammals have been studied, but not smaller mammals. The previous investigations correlated this fauna to the early Pliocene (early Ruscinian, MN 14). The present paper describes lagomorph remains which consist…

Over the last half a century, a massive amount of data has been gathered on Neogene rodents of Europe. Using the NOW database, we analysed changes in generic diversity during the Neogene and the beginning of the Quaternary. Studies as the present are useful for exploring major changes in diversity,…

The Staniantsi-Mazgoš Basin is one of several Neogene intramontane basins in NW Bulgaria. Recent fieldwork in the open pit coal mine yielded material of an exceptional diversity of vertebrates from the uppermost Miocene. In particular, skeletal remains of a large Castorinae are very numerous and…

Here we report about the presence of fossils belonging to different beaver lineages from the late Miocene (MN 9, Vallesian) of Grytsiv (western Ukraine). Among them, nine isolated molars were assigned to Chalicomys jaegeri and described in detail here for the first time. Morphologically…

The maxillary presented in this work has been excavated in the middle Miocene karst filling Petersbuch 136 (Germany, Bavaria) and shows the oldest evidence of dental anomaly in a sciurid. The aberrant morphology, probably hyperdontia or no replacement of roots of deciduous teeth, affects the area of…

In Asia, the first find of an eomyid rodent was reported almost one century after the first studies of the family Eomyidae in North America and Europe. Since then, eomyid rodents have been increasingly found in Asia particularly over the past two decades. Here, we review the Asian record of this…

An isolated mandible of Carnivora (Mammalia) from the phosphorites of Quercy (France) is described as a new genus. It is compared with the amphicyonid genus Cynodictis, some primitive North American amphicyonids, and with European and North American Eocene carnivoraforms. I conclude that it is…
