“…With the beginning of the Oligocene, the Desmatolagus lineage became diverse, abundant, and widespread throughout Central Asia (Sych, 1975;Huang, 1987;Wang, 2007), surviving until the Miocene, and possibly entering Europe (Early Oligocene, Vianey-Liaud and Lebrun, 2013) and North America (Late Oligocene; Dawson, 2008). Along with Desmatolagus, in the late Early/Middle Oligocene, the first plausible representatives of crown lagomorphs appear in Asia: Sinolagomys (an early ochotonid from China and Mongolia; see Erbajeva et al, 2017) and Ordolagus (probably an early leporid from China; Bohlin, 1942).…”

Due to their global distribution, invasive history, and unique characteristics, European rabbits are recognizable almost anywhere on our planet. Although they are members of a much larger group of living and extinct mammals [Mammalia, Lagomorpha (rabbits, hares, and pikas)], the group is often characterized by several well-known genera (e.g., Oryctolagus, Sylvilagus, Lepus, and Ochotona). This representation does not capture the extraordinary diversity of behavior and form found throughout the order. Model organisms are commonly used as exemplars for biological research, but there are a limited number of model clades or lineages that have been used to study evolutionary morphology in a more explicitly comparative way. We present this review paper to show that lagomorphs are a strong system in which to study macro- and micro-scale patterns of morphological change within a clade that offers underappreciated levels of diversity. To this end, we offer a summary of the status of relevant aspects of lagomorph biology.

“…M. Dawson was certainly correct when she suggested that the genus Sinolagomys with its derived characters in tooth morphology may lie at the base of the Bellatona lineage. Among the known species of the genus Sinolagomys, S. badamae Erbajeva (Erbajeva et al, 2017) shows greatest similarity with Bellatona. It is characterized by an elongated trigonid on the p3, which has rounded edges similar to what is observed in Bellatona kazakhstanica.…”

New data on the early and middle Miocene ochotonids of the genus Bellatona from the Valley of Lakes, Central Mongolia is based on the rich material collected by the team of the joint Austrian-Mongolian expeditions from the deposits of the Loo Formation. Three taxa: B. forsythmajori Dawson, 1961, B. yanghuensis Zhou, 1988, B. kazakhstanica Erbajeva, 1988 were discovered in the Mongolian fauna. This article presents morphological analysis and descriptions of taxa, comparison with known nominative species and their stratigraphic and geographical distributions.

Cenozoic sediments of the Taatsiin Gol and TaatsiinTsagaan Nuur area are rich in fossils that provide unique evidence of mammal evolution in Mongolia. The strata are intercalated with basalt flows. 40Ar/39Ar data of the basalts frame the time of sediment deposition and mammal evolution and enable a composite age chronology for the studied area. We investigated 20 geological sections and 6 fossil localities of Oligocene and early Miocene deposits from this region. Seventy fossil beds yielded more than 19,000 mammal fossils. This huge collection encompasses 175 mammal species: 50% Rodentia, 13% Eulipotyphla and Didelphomorphia, and 12% Lagomorpha. The remaining 25% of species are distributed among herbivorous and carnivorous large mammals. The representation of lower vertebrates and gastropods is comparatively poor. Several hundred SEM images illustrate the diversity of Marsupialia, Eulipotyphla, and Rodentia dentition and give insight into small mammal evolution in Mongolia during the Oligocene and early Miocene. This dataset, the radiometric ages of basalt I (∼31.5 Ma) and basalt II (∼27 Ma), and the magnetostratigraphic data provide ages of mammal assemblages and time ranges of the Mongolian biozones: letter zone A ranges from ∼33 to ∼31.5 Ma, letter zone B from ∼31.5 to ∼28 Ma, letter zone C from ∼28 to 25.6 Ma, letter zone C1 from 25.6 to 24 Ma, letter zone C1-D from 24 to ∼23 Ma, and letter zone D from ∼23 to ∼21 Ma.Electronic supplementary materialThe online version of this article (doi:10.1007/s12549-016-0257-9) contains supplementary material, which is available to authorized users.
