AI Insight
Paleontologists have discovered fossils of a heavily armored amphibian that lived in marine environments 237 million years ago in what is now China. The creature, approximately the size of a giant salamander, represents a remarkable exception to modern amphibians, which cannot tolerate full saltwater conditions. This finding may represent the first known case of an amphibian fully adapted to ocean life.
Why it matters
This discovery challenges our understanding of amphibian evolution and physiological limitations, demonstrating that ancient amphibians possessed capabilities their modern descendants have lost. It provides insight into how vertebrates transitioned between different aquatic environments and adapted to extreme conditions during the Triassic period.
Understand the Science
A bizarre, heavily armored amphibian roamed the oceans 237 million years ago, despite the fact that modern amphibians cannot survive entirely in saltwater. Discovered in China, the giant salamander-sized creature may be the first known amphibian to have adapted to a fully marine existence.
