Study of a growth series of twenty-seven specimens from the Upper Devonian of Escuminac Bay, Québec documents a complex pattern of vertebral development in the osteolepiform fish Eusthenopteron foordi ...

The iconic, armored, 14-foot-long Dunkleosteus was something of an "evolutionary oddball,” a new study has revealed.

New findings on the brain and inner ear cavity of a 400-million-year-old platypus-like fish cast light on the evolution of modern jawed vertebrates, according to a study led by Dr. ZHU Youan and Dr.

The Devonian System of western and central Colorado consists of a lower clastic unit, consisting of the McCracken, Elbert, and Parting Formations and an upper carbonate unit, the Dyer and Ouray ...

One of the best-documented evolutionary transitions is the appearance of tetrapods, the four-limbed vertebrates that now dominate the land. A large series of "fishapod" fossils have been discovered ...

Thirty years after 4,000 pristine fish fossils dating back 360 million years were discovered in regional NSW, a retired doctor is reopening the dig in the hope of finding the first animals to walk on ...

Climate change and asteroids are linked with animal origin and extinction – and plate tectonics also seems to play a key evolutionary role, ‘groundbreaking’ new fossil research reveals. The discovery ...

Scientists who famously discovered the lobe-finned fish fossil Tiktaalik roseae, a species with some of the clearest evidence of the evolutionary transition from fish to limbed animals, have described ...

About 360 million years ago, the shallow sea above present-day Cleveland was home to a fearsome apex predator: Dunkleosteus terrelli. This 14-foot armored fish ruled the Late Devonian seas with ...

“We call it a ‘fish-eat-fish world,’ an ecosystem where you really needed to escape predation,” said Dr. Ted Daeschler, describing life in the Devonian period in what is now far-northern Canada.

Origins of life The sexual act where two creatures physically join together to create new life first began 385 million years ago, according to a new fossil study. The extinct Devonian-age armoured ...
