Molecular data have transformed systematics, but should their absence automatically weaken a taxonomic study? Drawing on field experience and our recently published work on Euterpnosia cicadas, I argu...

Turiasaurian teeth from Angeac-Charente exhibit five dental morphotypes and reveal clear heterodonty and anteroposterior size gradient. Qualitative comparative anatomy quickly and efficiently identif....

Abstract. Evolutionary innovations bring species into new ecological zones by opening ecological opportunity. However, innovations can have varied effects

Destiné à reprendre l’industrie textile familiale, cet esprit libre a préféré la vie de chercheur d’os, découvrant plusieurs espèces d’animaux disparus, tout en menant une carrière institutionnelle de premier plan. Il s’est éteint le 16 novembre, à 85 ans.

Squamates (lizards, including snakes) are the most diverse group of terrestrial vertebrates on Earth today and have an evolutionary history dating back to at least the Middle Triassic (ca. 242 Mya). D...

A strange Jurassic lizard discovered on Scotland’s Isle of Skye is shaking up what we know about snake evolution. Named Breugnathair elgolensis, the “false snake of Elgol” combined hook-like, python-s...

Experts say the lizard-like creature, which has been given the Gaelic name Breugnathair elgolensis, had lived about 167 million years ago.

A new study of ancient, extinct fish known as placoderms provides another piece of the evolutionary puzzle about our deep time, aquatic ancestors.

The arthrodiran placoderm Bullerichthys fascidens, from the Late Devonian Gogo Formation, Western Australia, was originally described from an incomplete headshield with only the spinal and interolater...

Abstract. Understanding the rate of phenotypic evolution can reveal fundamental aspects of organismal evolutionary trajectories. Hence, several studies hav

Chimaeras (Holocephali) are an understudied group of mostly deep-ocean cartilaginous fishes (Chondrichthyes) with unique characteristics that disti...

New findings call into question one of the core assumptions about teeth. Adult male spotted ratfish, a shark-like species native to the eastern Pacific Ocean, have rows of teeth on top of their heads,...
