Procolophonidae was one of the most successful parareptile clades during the Triassic, becoming widespread across Pangea in the aftermath of the End-Permian Mass Extinction (EPME). The Lower Triass...

Dinosaur poop—possibly from a juvenile T. rex or Nanotyrannus—containing feathers, bone fragments, and fish scales provides a look at a Cretaceous-era food web.

A new study suggests that the presence of extraoral soft tissues — labial scales or "lips" for short — was not unique to extant lepidosaur reptiles (lizards, snakes, and tuataras), but rather represen...

The most complete record of the earliest dinosaur lineages is from the Carnian from the higher latitudes of Pangea (e.g. present-day Brazil, Argentina), but dinosaurian assemblages from the upper sta...

A new look at the "Dueling Dinosaurs" fossil reveals that Tyrannosaurus rex was not the only tyrannosaur roaming the land.

Seismometers picked up the ferocious winds and waves of Hurricane Melissa, showing how the tools can be used to better understand storms today and those from the past

The skull of the newly described dinosaur species was found “exposed on a cliff like a cabochon jewel” in the Eastern Gobi Desert.

A fossil of an extinct reptile known as a silesaur suggests that the size of early dinosaurs might have been underestimated.

Temporally constrained microvertebrate bone beds are powerful tools for understanding continent-scale biotic change. Such sites are rare globally i...

Long before T. rex, the Earth was dominated by super-carnivores stranger and more terrifying than anything dreamed up by Hollywood.

Late Triassic small and medium-sized vertebrates from the Fleming Fjord Group of the Jameson Land Basin, central East Greenland

A recent revision by Kischlat of the genus Prestosuchus (generally attributed to Huene) determined that it was an unavailable nomen nudum and proposed the new genus Huenesuchus to contain the species ...

The Upper Triassic outcrops from Brazil and Argentina have provided important information on the earliest stages of dinosaur radiation. Gracile dinosaurian taxa

Exquisite, fossilized skull sheds light on the evolutionary origins of waterfowl

Trialestes romeri (Upper Triassic, Ischigualasto Formation, NW Argentina) is the oldest Crocodylomorpha. Microstructural studies on its appendicular bones reveal that it possessed rapid growth dynami...

Abstract Sampling (or sample) bias is a widespread concern in scientific research, across...

The Upper Triassic lower Dharmaram Formation of India has yielded a highly diverse archosaur-dominated fauna that included a paratypothoracin aetosaur Venkatasuchus armatum, a plateosaurian sauropo...

Since the start of the twenty-first century, there has been a notable increase in annual publications focusing on dinosaur reproduction and ontogeny with researchers using these data to address a range of macroevolutionary questions about dinosaurs. ...

The paucity of small, skeletally immature individuals representing the earliest ontogenetic stages of extinct archosaurs complicates our understanding of the growth dynamics within and between specie....

Integrated analyses of bromalites provide robust pictures of past food webs, explaining early dinosaur evolution and the emergence of larger dinosaur faunas with new feeding patterns.

Crocodylomorphs constitute a clade of archosaurs that have thrived since the Mesozoic until today and have survived numerous major biological crises. Contrary to historic belief, their semiaquatic ex...
