TL;DR: The occurrence of dipodids implies that the Ertemte fauna and Harr Obo fauna represent an arid open steppe environment and that the dipodines are endemic to central Asia and part of northeastern Asia.
Abstract: This paper describes three dipodids —Paralactaga suniTeilhard & Young 1931,Brachyscirtetes wimani (Schlosser 1924) andSminthoides fraudator Schlosser 1924, collected by the Sino-German cooperative project in vertebrate palaeontology from Ertemte and Harr Obo, Inner Mongolia, in 1980. The Ertemte fauna contains the most abundant dipodids known in the Chinese Neogene mammalian faunas. It is shown that the three dipodines are endemic to central Asia and part of northeastern Asia. Comparisons with dipodines from the Pavlodar Formation, Kazakhstan, suggest thatProalactagaSavinov 1970 andScirtodipusSavinov 1970 are synonymous withParalactagaYoung 1927 andSminthoidesSchlosser 1924, respectively. The occurrence of dipodids implies that the Ertemte fauna and Harr Obo fauna represent an arid open steppe environment.

TL;DR: Early Ordovician ostracods appeared first in shallow marine, oxygenated environments on shelf margins, in a similar setting to other elements of the ‘Paleozoic fauna' as discussed by the authors.
Abstract: The oldest assumed ostracods appear in the fossil record from the TremadocianPaltodus deltifer conodont Biozone. Although geographically widespread these early ostracods have no obvious Cambrian antecedents. Their first appearance at ca. 485 Ma contrasts with molecular evidence that suggests a much earlier (latest Proterozoic or Cambrian) origin for ostracods. Some Cambrian bivalved arthropods such asAltajanella andVojbokalina, conventionally referred to the Bradoriida, have carapace morphologies that resemble Ordovician palaeocopid ostracods, though such a relationship is unproven without soft part anatomy. Evidence from preserved soft anatomy demonstrates that Bradoriida, such asKunmingella, and Phosphatocopida, essentially the Cambrian ‘ostracod’ record of traditional usage, belong outside the Eucrustacea. Early Ordovician ostracods appeared first in shallow marine, oxygenated environments on shelf margins, in a similar setting to other elements of the ‘Paleozoic fauna’. Their biodiversity was low (3 named genera and ca. 12 species), though some taxa such asNanopsis andEopilla achieved widespread dispersal between major Ordovician palaeocontinents. As bradoriids were largely extinct by the Late Cambrian, ostracods do not appear to have directly competed with them for shallow marine environments. The rapid colonisation of these settings by ostracods may have been facilitated by the available ecospace vacated by Bradoriida.

TL;DR: This population is therefore one of the oldest of the genus Arvicola, confirmed by SDQ and tooth length values indicating a primitive evolutionary stage, and the age of the population correlates with either Cromer Interglacial III or IV.
Abstract: Arvicola materials from Mosbach 2, including the types ofA. mosbachensis housed at the Forschungsinstitut Senckenberg Frankfurt am Main, are described. Six specimens display incipient root development. This population is therefore one of the oldest of the genusArvicola. This is confirmed by SDQ and tooth length values indicating a primitive evolutionary stage. The age of the population correlates with either Cromer Interglacial III or IV.

TL;DR: The Bilike micromammals mirror a temperate environment of steppe or grassland, interspersed with local forests, dense thickets, and freshwater bodies, and indicate an environmental change to drier, more steppic conditions.
Abstract: Excavations at the fossil site Bilike, Huade County, Inner Mongolia Autonomous Region, in 1986 and 1991 produced the most diverse and abundant micromammalian fauna known from the Pliocene of China. A total of 6.500 specimens is described and referred to 50 species from 41 genera and 13 families of insectivores, bats, rodents, hares, and pikas. Described as new areParasoriculus tongi n. g., n. sp.,Prospermophilus n. g.,Sinozapus volkeri n. g., n. sp.,Allorattus engesseri n. g., n. sp.,Petenyia katrinae n. sp.,Sulimskia ziegleri n. sp.,Sicista wangi n. sp.,Sinocricetus progressus n. sp.,Kowalskia zhengi n. sp.,Aratomys bilikeensis n. sp.,Apodemus lii n. sp.,Orientalomys sinensis n. sp.,Chardinomys bilikeensis n. sp.,Trischizolagus mirificus n. sp. New for the Chinese fossil record are the generaPetenyia, Sulimskia, andAratomys.
