Their ancient ancestors (known as acanthodians) were even more prickly, with bristly spines along their fins. Now, a new fossilized fish skeleton found in China is older than the next-oldest ...

Life on Earth began in the water. When animals moved onto the ground, they switched fins for limbs. But how exactly did that happen? US scientists say they may have stumbled on a possible answer.

Bone structure matters, too. Most fish that will end up on your cutting board will have similar skeletal features, allowing you to fillet them with the steps outlined below. As an example, although a ...

The skeletal structure of a fish's gill arches and paired fins are quite similar – enough so that it was once believed the fins evolved from the arches. Although that theory has since been ...

The Research Brief is a short take about interesting academic work.. The big idea. Segmented hinges in the long, thin bones of fish fins are critical to the incredible mechanical properties of ...

Research on fossilized fish details the evolution of fins as they began to transition into limbs fit for walking on land. Research on fossilized fish from the late Devonian period, roughly 375 ...

There was thought to be little in common between fish fin bones and the finger bones of land-dwellers. But zebrafish studies reveal that hox genes have a surprisingly similar role in patterning ...

ELPISTOSTEGE WATSONI, a 375-million-year-old fish closely related to four-limbed animals, had digit bones in its pectoral fins that could have helped support the animal's weight on land.

This week in the journal Proceedings of the Royal Society B, a team of French and Swedish researchers present the earliest fossil evidence for the presence of bone marrow in the fin of a 370 ...
