Fossils of a new species of carnivorous fish that lurked ancient rivers have been discovered in the Canadian Arctic as per a new study. It was the research scientists at Academy of Natural Sciences in ...

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 ...

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.

“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.

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 ...

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 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 ...

First teeth The world's first teeth grew outside of the mouth before later moving into the oral cavity, new research on Early Devonian fish suggests. The study, published in the Journal of Vertebrate ...

The story of how vertebrates got their teeth is much older than researchers realized, new findings show. In a paper published Thursday in the journal Science, scientists examined the teeth of three ...

We think of mass extinctions as brief moments of havoc — profoundly devastating but over within a geologic instant. The Devonian, the second of the so-called "Big Five,” defies this notion. If the ...
