Researchers reporting in Current Biology on April 2 have evidence that an extinct species of monitor lizard had four eyes, a first among known jawed vertebrates. Today, only the jawless lampreys have four eyes.
Just a week after scientists reported evidence that our species left Africa earlier than we thought, another discovery is suggesting the date might be pushed back further.
An unusual spider lurks in Madagascar's rainforests.
Scientists in the USC Stem Cell laboratory of Gage Crump have revealed how key genes guide the development of the jaw in zebrafish. These findings may offer clues for understanding craniofacial anomalies in human patients, ...
In biology, one long-running debate has teeth: whether ancient fish scales moved into the mouth with the origin of jaws, or if the tooth had its own evolutionary inception.
The decomposing body of a dead humpback whale surprised swimmers when it washed up on Rio de Janeiro's iconic Ipanema beach Wednesday.
A massive, wolf-sized otter that lived about 6 million years ago may have been a dominant predator in its time, according to a new study analyzing the animal's jaws.
A team of researchers with members affiliated with several institutions in Belgium and France has identified the fossilized remains of a dinosaur from approximately 84 to 72 million years ago. In their paper published in ...
New Macquarie University research, published in the journal Proceedings of the Royal Society B, has shown that birds and pterosaurs did, in fact, co-exist for millions of years peacefully, as opposed to the long-held and ...
Once you know that many dinosaurs had feathers, it seems much more obvious that they probably evolved into birds. But there's still a big question. How did a set of dinosaurian jaws with abundant teeth (think T. rex) turn ...
