A unique characteristic of mammals is a vertebral column with anatomically distinct regions,
but when and how this trait evolved remains unknown. We reconstructed vertebral regions …

Mammals are arguably the most conspicuous tetrapods in the modern biota. Although there
are fewer extant mammal species (~ 5,500) than birds (~ 10,000) or squamates (~ 10,000) …

Anomodontia was the most successful herbivorous clade of the mammalian stem lineage
(non‐mammalian synapsids) during the late Permian and Early Triassic. Among …

We describe tetrapod burrows from the uppermost Middle–lower Upper Triassic (latest

New technologies can upset scientific workplaces' established practices and social order.
Scientists may therefore prefer preserving skilled manual work and the social status quo to …

Abstract The lower Washington Formation of the Lower Permian (Asselian) Dunkard Group

Large-diameter burrows in pedogenically modified floodplain deposits in the Salt Wash
Member, Upper Jurassic Morrison Formation, southeast Utah, USA, are interpreted to have …

Tetrapod burrow records are rare in the pre-Cenozoic strata of China. Here we report three
casts of vertebrate burrows from the Ermaying Formation at Xizhen, Jiaxian, Shaanxi, China …

Although phylogenetic methods tend to atomize living things into discrete parts with the
presumption that they evolve independently, the characteristics of organisms evolve …
