The discovery of Entelognathus from the Late Silurian (Ludlow) Xiaoxiang ve... A weird combination of Deinotherium and Platybelodon- Elephantiformes without ivories, which were discovered by IVPP 　　In the main Proboscidean taxon of Elephantiformes, a huge pair of developed top incisors (ivories) has become a distinctive feature of this taxon. The structure is usually made as a tool for individual foraging and a weapon for males to compete for mating. The Proboscidean taxon without ivories usually and only... New Old World Vulture Found from the Late Miocene of China 　　Neogene fossils of Old World vultures (Aegypiinae and Gypaetinae) are known from Africa, Eurasia, and North America. The evolution of Old World Vultures is closely tied to the expansion of grasslands and open woodlands and appearance of large, grazing mammals. While there are no extant Old World vultures in th... New Finding from Southern China Helps Understanding the Feeding Ecology of Pleistocene Proboscideans 　　The proboscidean fossil record in China is characterized by a high evolutionary rate, wide spatio-temporal distribution and richness of environmental indicators. Therefore, proboscideans make important indicator fossils for reconstructing terrestrial palaeoenvironments in the Chinese late Cenozoic. 　　In recen... New Symmetrodont Mammal Found from the Early Cretaceous of China 　　Mesozoic mammals with molariform teeth bearing a simple, triangular arrangement of principal cusps were traditionally assigned to the Order Symmetrodonta. Phylogenetic analyses imply that this grouping is artificial, with the symmetrodont molar pattern representing a structural grade that evolved multiple times... Devonian Fish Provides Unique Insights into the Early Evolution of Modern Lobe-finned Fishes 　　Crown or modern sarcopterygians contain three major groups: coelacanths, lungfishes and tetrapods. With the exception of the tetrapods, sarcopterygians have a long evolutionary history of diversity decline and are nowhere near as diverse today as they were at the beginning of their history. They differ substant... Oldest Actinopterygian from China Provides New Evidence for the Origin of Ray-Finned Fishes 　　Osteichthyans or bony fishes comprise two divisions, each containing over 32,000 living species: Sarcopterygii (lobe-finned fishes and tetrapods) and Actinopterygii (ray-finned fishes). Nevertheless, actinopterygians have an obscure early evolutionary history. The earliest definitive actinopterygian is the Midd... New Species from the Pliocene of Tibet Reveals Origin of Ice Age Mountain Sheep 　　Modern wild sheep, Ovis, is widespread in the mountain ranges of the Caucasus through Himalaya, Tibetan Plateau, Tianshan-Altai, eastern Siberia, and the Rocky Mountains in North America. In Eurasia, fossil sheep are known by a few isolated records at a few Pleistocene sites in North China, eastern Siberia, and... New Oligocene Primates from China Highlight Key Evolutionary Period 　　Profound environmental and faunal changes are associated with climatic deterioration during the Eocene-Oligocene transition (EOT) roughly 34 million years ago. Primates are among the most environmentally sensitive of all mammals. Reconstructing how Asian primates responded to the EOT has been hindered by a spar... Scientists Report World’s First Herbivorous Filter-feeding Marine Reptile 　　Some strange creatures cropped up in the wake of one of Earth’s biggest mass extinctions 252 million years ago. In 2014, scientists discovered a bizarre fossil--a crocodile-sized sea-dwelling reptile, Atopodentatus unicus, that lived 242 million years ago in what today is southwestern China. Its head was poorl...   28 Page(s)   FirstPrev12345NextFinal
