Feroxichthys panzhouensis sp. nov., a hump-backed colobodontid (Neopterygii, Actinopterygii) from the early Middle Triassic of Panzhou, Guizhou, China [PDF]
PeerJ, 2021 Neopterygii is a taxonomically diverse clade of ray-finned fishes, including Teleostei, Holostei and closely related fossil taxa. The Colobodontidae is a stem group of large-sized neopterygians with a durophagous feeding adaption from the Middle to Late ...

The first pterosaur basihyal, shedding light on the evolution and function of pterosaur hyoid apparatuses [PDF]
PeerJ, 2020 The pterosaur is the first known vertebrate clade to achieve powered flight. Its hyoid apparatus shows a simplification similar to that of birds, although samples of the apparatus are rare, limiting the ability to make an accurate determination.

An Early Cretaceous enantiornithine (Aves) preserving an unlaid egg and probable medullary bone
Nature Communications, 2019 The fossil record of the reproductive traits of early birds is limited. Here, Bailleul and colleagues describe the Cretaceous enantiornithine bird Avimaia schweitzerae, which preserves an unlaid egg in the abdominal cavity and putative medullary bone.

Human and Ape Molecular Clocks and Constraints on Paleontological Hypotheses [PDF]
Journal of Heredity, 2001 Although the relationships of the living hominoid primates (humans and apes) are well known, the relationships of the fossil species, times of divergence of both living and fossil species, and the biogeographic history of hominoids are not well established.

An Oligocene giant rhino provides insights into Paraceratherium evolution
Communications Biology, 2021 Deng et al. report a new species of giant rhino, Paraceratherium linxiaense, from specimens of the upper Oligocene Jiaozigou Formation in China with an age of 26.5 Ma. Morphological analysis of the completely preserved skull with articulated mandible and
