This fish, measuring up to 9 feet (2.7 meters) long, is the largest bony fish on record from the Late Devonian (383 million to 359 million years ago) and was predatory, prompting researchers to ...

Dunkleosteus was a massive armored fish that ruled the Devonian seas over 358 million years ago. With powerful, self-sharpening jaws and an immense bite force, it was one of the most fearsome ...

The Devonian ancestors of fishes living today belonged to two main nonarmored groups. The cartilaginous fish, so-called because cartilage formed their skeletons, later gave rise to sharks and rays.

Dunkleosteus is a prehistoric fish, one of the largest arthrodire placoderms ever to have lived, existing during the Late Devonian period, about 380-360 million years ago. This hunter, measured up ...

A Late Devonian coelacanth reconfigures actinistian phylogeny, disparity, and evolutionary dynamics. Nature Communications , 2024; 15 (1) DOI: 10.1038/s41467-024-51238-4 Cite This Page : ...

A pregnant fossil fish at the Natural History Museum in London has shed light on the possible origin of sex, according to a new study. Dating from the Upper Devonian period 365 million years ago ...

The extinction began roughly 380 million years ago, midway through the segment of geologic time known as the Devonian period, or the age of fish. (Vertebrates hadn’t yet made the leap onto land.) The ...

The now-extinct Tiktaalik lived during the Devonian period (aka the Age of Fishes) of the Paleozoic geological era. It may not be as sexy as the age of dinosaurs’ Mesozoic era, which came much later, ...

Polypterid fish were considered to be archaic outliers of the bony-fish grouping. Fossil analysis now places them at the heart of early ray-finned fishes, a radical change that transforms the ...

The coelacanth - a wondrous fish that was thought to have gone extinct along with the dinosaurs 66 million years ago before unexpectedly being found alive and well in 1938 off South Africa's east ...

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 ...
