Article
Full-text available
The aridification of Central Asia since the Eocene has widespread evidence, but climate-controlled environmental reorganizations during the Oligocene remain ambiguous. We employed environmental magnetic, mineralogical and geochemical methods on a latest Eocene to late Oligocene terrestrial sequence in Inner Mongolia, China, to examine how global cl...
Article
Full-text available
Robust regional chronostratigraphic framework is the basis of understanding climatic and faunal events in the geologic history. One of the most dramatic faunal turnovers of the past 50 million years in Asia is linked to the Eocene-Oligocene Transition (EOT) at about 34 Ma. However, the chronostratigraphic relationships between faunal modulation and...

Constraining the provenance of aeolian mineral dust is critical in understanding past climate changes, atmospheric dust activity, circulation, and sediment generation. On the Chinese Loess Plateau (CLP), use of detrital zircon U-Pb age data as source tracers for the dust has seen a huge growth and lead to breakthroughs in understanding dust provena...

Full-text available
The Early Oligocene is a critical time for global climate changes in the Cenozoic. This epoch witnessed severe mammalian faunal turnovers known as "Grande Coupure" in Europe and "Mongolian Remodelling" in Asia. However, insights about morphological changes in Oligocene mammal lineages have not been explored in detail. One of the least diversified g...

Here we report a Hipparion fauna locality discovered in between two basalt layers near Hanjiaying Village, Jining District, Wulanchabu City, Nei Mongol. K-Ar isotopic dating of the lower and upper level of the basalt constrains the age of the fauna from 7.2 to 6.8 Ma. Compared with classical Hipparion fauna from northern China, the Hanjiaying fauna...
Article
The occurrence of Nyctereutes during the Plio-Pleistocene has long been reported in northern China, with the highest abundance in the Nihewan Basin. However, due to site dispersal, the coexistence of different taxa, and lack of a precise stratigraphic constraint, the evolutionary process of this genus remains enigmatic. In this study, we re-examine...
Article
Full-text available
Cenozoic mammal evolution and faunal turnover are considered to have been influenced and triggered by global climate change. Teeth of large terrestrial ungulates are reliable proxies to trace long‐term climatic changes due to their morphological and physicochemical properties; however, the role of premolar molarization in ungulate evolution and rel...
Article
Full-text available
The transition from Eocene to Oligocene and its implications in the terrestrial realm has been a focal target for Cenozoic climate and environment research as it is widely considered the most dramatic climatic shift of the past 50 million years. Tibetan Plateau and proximal areas have been of utmost interest since the biogeographic relationships an...
Article
Full-text available
Deperetellidae is a clade of peculiar, Asian endemic tapiroids from the early and middle Eocene. The previously published material mainly comprises maxillae, mandibles, and some postcranial elements. However, the absence of cranial materials and primitive representatives of the deperetellids obscures their phylogenetic relationships within Tapiroid...
Article
Full-text available
The evolution of molar teeth from low-crowned (brachyodont) to high-crowned (hypsodont) has traditionally been recognized as a response to increasing tooth wear due to endogenous (e.g., fiber, silica) and/ or exogenous (e.g., dust, grit) properties of ingested food. Recent work indicates that the mean hypsodonty level of large herbivorous land mamm...

Predation is the most common cause of death in small mammals. It also causes the greatest modification on their remains. Other postmortem processes, such as weathering, trampling, and transportation all modify bones and contribute to the forming assemblage. Here we examined three Miocene localities from Damiao, Nei Mongol, China with different fluv...
Article
Full-text available
After a long period of inactivity, recent excavations at the late Miocene Maragheh Formation unexpectedly resulted in the discovery of the first fossil hominoid and second Mesopithecus remains from this area. The discovery motivated a new international initiative to conduct research in these rich fossil sites. These studies focused on the fossil ho...

Full-text available
The Ulantatal area is well-known for its extraordinarily rich Oligocene mammalian fossils. The Ulantatal fauna was originally considered to be the representative fauna for the Chinese Land mammalian Age, Ulantatalian. However, the abundant fossils collected in the 1980s lack coordinates and/or detailed stratigraphic levels, and have been lumped tog...

1. Although Lagomorpha (rabbits, hares and pikas) have a long evolutionary history in Eurasia and Africa, including primitive genera of Eurasia historically considered assignable at the family level to Leporidae, the predecessors of modern rabbits were absent throughout this vast region for most of the Miocene until late in that epoch. During the e...

Although highly diversified in their early history, only one genus in Ochotonidae, Ochotona, survives to the present. Ochotona is generally accepted to have originated from the Middle Miocene Bellatona. During the 2006–2010 field seasons, we found Miocene localities at Damiao, Siziwang Qi, Nei Mongol, which produced rich materials of ochotonids. Of...
Article
The expansion of C4 plants is thought to have profound effects on the faunal turnover of large mammals during the latest Miocene. However, it is unclear whether this event also induced extinction and range contraction of small mammals. Pikas (Ochotonidae) are highly adapted to arctic or alpine environments, and are considered ideal indicators in bi...
