Yantanglestes is a genus of small, Chinese mesonychid with slender jaws that first appeared during the Early Paleocene in the Thanetian stage. It was found throughout Asia. It is the oldest known mesonychid. Yantanglestes became extinct during the Nongshanian division of the Late Paleocene, [2] and lived sympatrically with its descendant genera, including Dissacus , Sinonyx and Jiangxia . [2]
is one of ten urban districts of the prefecture-level city of Hangzhou, the capital of Zhejiang Province, East China. Fuyang is located in the northwest of Zhejiang on the Fuchun River, a tributary of the Qiantang River. The city is the birthplace of numerous notable individuals, including modern Chinese short story writer and poet Yu Dafu.
Mesonychia is an extinct taxon of small- to large-sized carnivorous ungulates related to artiodactyls. Mesonychids first appeared in the early Paleocene, went into a sharp decline at the end of the Eocene, and died out entirely when the last genus, Mongolestes, became extinct in the early Oligocene. In Asia, the record of their history suggests they grew gradually larger and more predatory over time, then shifted to scavenging and bone-crushing lifestyles before the group became extinct.
The Institute of Vertebrate Paleontology and Paleoanthropology of China is a research institution and collections repository for fossils, including many dinosaur and pterosaur specimens. As its name suggests, research is focused on both paleontological topics and those relating to human prehistory.
Mesonychidae is an extinct family of small to large-sized omnivorous-carnivorous mammals. They were endemic to North America and Eurasia during the Early Paleocene to the Early Oligocene, and were the earliest group of large carnivorous mammals in Asia. They are not closely related to any living mammals. Mesonychid taxonomy has long been disputed and they have captured popular imagination as "wolves on hooves," animals that combine features of both ungulates and carnivores. Skulls and teeth have similar features to early whales, and the family was long thought to be the ancestors of cetaceans. Recent fossil discoveries have overturned this idea; the consensus is that whales are highly derived artiodactyls. Some researchers now consider the family a sister group either to whales or to artiodactyls, close relatives rather than direct ancestors. Other studies define Mesonychia as basal to all ungulates, occupying a position between Perissodactyla and Ferae. In this case, the resemblances to early whales would be due to convergent evolution among ungulate-like herbivores that developed adaptations related to hunting or eating meat.
Sinobrachyops placenticephalus is an extinct temnospondyl amphibian from Middle Jurassic-aged Shaximiao Formation in the Sichuan basin, China. S. placenticephalus is one of the youngest known labyrinthodont amphibians.
Shaanbeikannemeyeria is an extinct genus of dicynodont known from the Early Triassic of China. It contains a single species, S. xilougoensis, which was described in 1980 by Zheng-Wu Cheng from a skull catalogued as IGCAGS V315. The specimen was lost, and a neotype skull IVPP V 11674 was later designated. A second species, S. buergondia, was named by Jin-Lin Li in 1980 from a partial skeleton, but it has since been regarded as a synonym of S. xilougoensis.
