New Yuomys rodents from southeastern Qinghai-Tibet Plateau indicate low elevation during the Middle Eocene

Frontiers in Earth Science, 2023
Yuomys are medium-sized Hystricomorpha rodents. They are known for coming from areas of low elevation in China during the middle and late Eocene. Two new Yuomys were discovered from a locality near Xueshuo village in Litang County, Sichuan Province.

Preliminary Discussion on the Highly Radiogenic Lead in Unalloyed Copper Artifacts of the Eastern Zhou Dynasty: Starting from the Huili Copper Spearheads

Metals, 2020
The debate about the highly radiogenic lead in Chinese archaeology has never ceased. However, previous studies have mainly focused on high leaded bronzes and lead materials, and with little specific discussion on the unalloyed copper artifacts and the ...

Middle ear innovation in Early Cretaceous eutherian mammals

Nature Communications, 2023
The middle ear ossicles in modern mammals are repurposed from postdentary bones in non-mammalian cynodonts. Recent discoveries by palaeontological and embryonic studies have developed different models for the middle ear evolution in mammaliaforms ...

Medullary bone in an Early Cretaceous enantiornithine bird and discussion regarding its identification in fossils

Nature Communications, 2018
Medullary bone is used by modern female birds as a calcium reservoir for eggshell production. Here, O’Connor and colleagues propose criteria for identifying medullary bone in fossils and report medullary bone from a Cretaceous enantiornithine bird fossil.

Holocene Vegetation Succession and Response to Climate Change on the South Bank of the Heilongjiang-Amur River, Mohe County, Northeast China

Advances in Meteorology, 2016
Pollen samples from peat sediments on the south bank of the Heilongjiang River in northern Northeast China (NE China) were analyzed to reconstruct the historical response of vegetation to climate change since 7800 cal yr BP.

Perissodactyl diversities and responses to climate changes as reflected by dental homogeneity during the Cenozoic in Asia

Ecology and Evolution, 2020
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 ...

Savanna ecosystems and mammalian adaptations in Mid-Miocene Northern China

Scientific Reports
The paleoenvironments and ecosystems of northern China during the Miocene (ca. 23–5.3 Ma) are complex topics, especially concerning the uplift of the Tibetan Plateau on the surrounding areas and the ecological adaptations of mammals as a consequence. Our

Paleontological Tests: Human-Like Intelligence Is Not a Convergent Feature of Evolution [PDF]

, 2008
We critically examine the evidence for the idea that encephalization quotients increase with time. We find that human-like intelligence is not a convergent feature of evolution. Implications for the search for extraterrestrial intelligence are discussed.

The role of teeth in mammal History

Brazilian Journal of Oral Sciences, 2015
Teeth are more than hard structures for cutting, grinding and/or crushing food. Teeth, living or dead, have much to contribute to the study of ecology, paleontology, functional morphology and systematic.
