Abstract

Dolhești-1 is located 50 km south of Iași town (Iași County), in the northeast part of Romania. The sedimentary deposits exposed at Dolhești-1 belong to the last megacycle of the Moldavian Platform. Approximately one ton of sediment was screen-washed to collect the fossils using stable sieves. The most essential fossil elements identified in the locality were teeth of small mammals. More than 30 teeth were identified belonging to nine taxa: Hansdebruijnia erksinae, Neocricetodon progressus, Vasseuromys pannonicus, Myomimus dehmi, Hylopetes aff. hoeckarum, Sciuridae indet., Ochotona eximia, Schizogalerix cf. sarmaticum, and Crusafontina cf. kormosi, the rodents being the most diverse group. Based on the presence of Vasseuromys pannonicus, the age of the small mammal assemblage is interpreted as early Turolian (MN 11, Late Miocene). The genera Vasseuromys, Hylopetes, and Hansdebruijnia are reported for the first time in the Late Miocene of eastern Romania. This small mammal assemblage identified from Dolhești-1 represents the first early Turolian microvertebrate findings from the Late Miocene of Romania. The diversity of this faunal association represents an advantage for the interpretation of the paleoenvironment. Furthermore, the discovery of these taxa constitutes an important contribution to the study of small mammals from the Late Miocene of the Eastern Carpathians Foreland, adding new data about Turolian localities in Eastern Europe.

期刊介绍： Geobios publishes bimonthly in English original peer-reviewed articles of international interest in any area of paleontology, paleobiology, paleoecology, paleobiogeography, (bio)stratigraphy and biogeochemistry. All taxonomic groups are treated, including microfossils, invertebrates, plants, vertebrates and ichnofossils. Geobios welcomes descriptive papers based on original material (e.g. large Systematic Paleontology works), as well as more analytically and/or methodologically oriented papers, provided they offer strong and significant biochronological/biostratigraphical, paleobiogeographical, paleobiological and/or phylogenetic new insights and perspectices. A high priority level is given to synchronic and/or diachronic studies based on multi- or inter-disciplinary approaches mixing various fields of Earth and Life Sciences. Works based on extant data are also considered, provided they offer significant insights into geological-time studies.
