Of the six or more different species of early humans, all belonging to the genus Homo, only we Homo sapiens have managed to survive. Now, a study reported in the journal One Earth today (October 15, 2020) combining climate modeling and the fossil record in search of clues to what led to […]

Artist’s rendering of Gavialimimus almaghribensis, a newly discovered species of mosasaur that ruled the seas of what is now Morocco some 72 to 66 million years ago. Credit: Tatsuya Shinmura Ancient lizard’s long, crocodile-like snout suggests it carved out a niche in a competitive marine ecosystem. A new species of […]

A new study shows that the body size of the iconic gigantic Megalodon or megatooth shark, about 50 feet (15 meters) in length, is indeed anomalously large compared to body sizes of its relatives. Formally called Otodus megalodon, the fossil shark that lived nearly worldwide roughly 15-3.6 million years ago is […]

A life-scene from 232 million years ago, during the Carnian Pluvial Episode after which dinosaurs took over. A large rauisuchian lurks in the background, while two species of dinosaurs stand in the foreground.

Ultimately, this study provides overwhelming evidence that this Jurassic feather came from the ancient wing of flying dinosaur Archaeopteryx, reconstructed here in 3D. Credit: Ryan Carney A new study provides substantial evidence that the first fossil feather ever to be discovered does belong to the iconic Archaeopteryx, a bird-like dinosaur […]

Summary of major extinction events through time, highlighting the new, Carnian Pluvial Episode at 233 million years ago. Credit: D. Bonadonna/ MUSE, Trento It’s not often a new mass extinction is identified; after all, such events were so devastating they really stand out in the fossil record. In a new […]

ANIMATION Sharks’ non-bony skeletons were thought to be the template before bony internal skeletons evolved, but a new fossil discovery suggests otherwise. The discovery of a 410-million-year-old fish fossil with a bony skull suggests the lighter skeletons of sharks may have evolved from bony ancestors, rather than the other way […]

Field site in Ramnagar, India. Credit: Christopher Gilbert The 13-million-year-old gibbon ancestor fills major gaps in the primate fossil record. A 13-million-year-old fossil unearthed in northern India comes from a newly discovered ape, the earliest known ancestor of the modern-day gibbon. The discovery by Christopher C. Gilbert, Hunter College, fills […]
