A newly discovered Chinese fossil, Meemannia, is the oldest known actinopterygian, providing new evidence for the origin of ray-finned fishes. The study reveals that early bony fish had 'cosmine'-like tissues, previously thought to unite lobe-fins and ray-fins, and confirms Meemannia as an early-diverging ray-finned fish.
The discovery of Protovis himalayensis sheds light on the origin of Ice Age mountain sheep, suggesting that the Tibetan Plateau was their ancestral home range. The fossil finds indicate a C3 diet and adaptation to high-elevation cold environments during the Pliocene.
The discovery of diverse Oligocene primates from southern China sheds light on the evolution of primates during the Eocene-Oligocene transition. The Asian fauna is dominated by strepsirhines, contrasting with Afro-Arabian primate faunas that diversified anthropoids after the climate crisis.
Researchers have discovered a remarkable new species of marine reptile that lived during the Triassic Period. Atopodentatus unicus was an herbivore with a hammerhead-shaped jaw apparatus and used its teeth to filter-feed on plants from the ocean floor.
A newly discovered enantiornithine bird from the Early Cretaceous period in China provides the oldest unambiguous record of an avian gastric pellet. The fossilized remains include a fish-rich pellet, suggesting that some Early Cretaceous birds had evolved modern avian digestive features.
