The world’s largest living amphibian, the Chinese giant salamander (Andrias davidianus), is capable of feeding not only on prey located directly in from of it, but also on creatures which approach from the side, thanks to a newly-discovered quick-strike technique.
This ugly fish uses water to form a tongue-like apparatus to help it eat on land.
A two-faced fish more than 400 million years old is likely the last common ancestor of all jawed vertebrates--including us--and provides additional evidence that sharks are not primitive creatures, as had long been assumed.
While the fossil record has found that wrists and fingers have an aquatic origin, previous attempts to link fingers and fins have proven unsuccessful. Now, though, a team led by University of Chicago researchers has discovered the reason why: scientists were studying the wrong fish.
Paleontologists from the University of Zurich now reveal that climate catastrophes in the past played a crucial role in the dominance of ray-finned fish today.
About 400 million years ago a group of fish began exploring land and evolved into tetrapods – today's amphibians, reptiles, birds, and mammals. But just how these ancient fish used their fishy bodies and fins in a terrestrial environment and what evolutionary processes were at play remain scientific mysteries.
Despite having retained their basic "sharkiness" for millions of years, modern sharks have less to tell us about the early evolution of jawed vertebrates—including humans—than was previously thought.
Researchers from the University of Valencia and the Natural History Museum of Berlin have studied the fossilized remains of scales and bones found in Teruel and the south of Zaragoza, ascertaining that they belong to a new fish species called Machaeracanthus goujeti that lived in that area of the peninsula during the Devonian period.
The evolutionary path from the bone structure of the fish to the complex, weight-bearing hips of walking animals was a much simpler process than previously thought, according to a new study.
Using high-energy X-rays and a new data extraction protocol, an international consortium of scientists have for the first time rendered a 3D model of a prehistoric tetrapod backbone.
