The phylogenetic affinities and morphological peculiarities of the bird-like dinosaur Borogovia gracilicrus from the Upper Cretaceous of Mongolia [PDF]
PeerJ, 2021 Borogovia gracilicrus is a small-bodied theropod dinosaur from the Maastrichtian (Upper Cretaceous) Nemegt Formation of southern Mongolia. The taxon is based on a single fragmentary specimen preserving only the distal part of the hindlimbs.

Body mass estimation in Triassic cynodonts from Argentina based on limb variables
Acta Palaeontologica Polonica, 2022 Body mass estimations for extinct taxa are fundamental in palaeobiological reconstructions, but little work has been done on this topic for non-mammaliaform cynodonts (NMC), the diverse and abundant Permo-Cretaceous forerunners of mammals.

Faunal Assemblages From Lower Bed I (Oldupai Gorge, Tanzania)
Frontiers in Ecology and Evolution, 2022 Palaeobiological and archeological excavations at the site of Ewass Oldupa, found in the western Plio-Pleistocene rift basin of Oldupai Gorge (also Olduvai Gorge), Tanzania, revealed rich fossiliferous levels and the earliest remains of human activity at

Bone microstructure of the sphenodont rhynchocephalian Priosphenodon avelasi and its paleobiological implications [PDF]
Acta Palaeontologica PolonicaSphenodontians are a group of vertebrates with a vast taxonomic diversity and worldwide distribution of their fossils. Although they have been the subject of many studies on their phylogeny and morphology, those focused on their paleobiology are still ...

Rivista Italiana di Paleontologia e Stratigrafia, 2017 Several taxa belonging to the so called megafauna became extinct during the late Quaternary in Eurasia. The extinction chronology of the narrow-nosed rhinoceros, Stephanorhinus hemitoechus, in Europe is still uncertain and only estimated around 45 ka.

Estimating the evolutionary rates in mosasauroids and plesiosaurs: discussion of niche occupation in Late Cretaceous seas [PDF]
PeerJ, 2020 Observations of temporal overlap of niche occupation among Late Cretaceous marine amniotes suggest that the rise and diversification of mosasauroid squamates might have been influenced by competition with or disappearance of some plesiosaur taxa.

Climate and cultural evolution drove Holocene cropland change in the Huai River Valley, China
iScienceSummary: As an important way of maximizing land productivity by growing more than one crop type in the same field, mixed cropping has been an effective option for sustaining population growth under different climatic conditions since prehistoric period ...

Geological Society of America Bulletin, 2012 Systems paleobiology seeks to interpret the history of life within the framework of Earth’s environmental history, using physiology as the conceptual bridge between paleontological and geochemical data sets. In some cases, physiological performance can be estimated directly and quantitatively from fossils—this is commonly the case for vascular plant ...
