Lower-jaw teeth in frogs re-evolved after an absence of 200 million years, challenging evolutionary thinking, scientists say.

The ancestors of frogs and toads were armed with large fangs and thousands of hook-like denticles, making their modern counterparts look a bit gummy by comparison. Do frogs have teeth? Yes, but ...

This mysterious frog re-evolved a full set of teeth More than 200 million years ago, modern frogs’ ancestors lost the teeth in their lower jaws. How did Guenther’s marsupial frog regain them?

Frogs aren’t alone If it sounds strange to lose, re-grow, and then lose teeth again, I would agree ― but we have to remember, nature is nothing if not odd.

Nearly all frogs lack teeth on their lower jaw, but some, such as Budgett's frogs, have evolved lower fanglike structures that allow them to inflict puncture wounds on their prey.

Florida Museum of Natural History researchers analyzed CT scans of nearly every living amphibian genus to reveal that frogs have lost teeth over 20 times during their evolution, more than any ...

Researchers analyzed CT scans of nearly every living amphibian genus to reveal that frogs have lost teeth over 20 times during their evolution, more than any other vertebrate group.

Researchers from the Indian Institute of Science’s (IISc.) molecular biophysics unit in a study have identified that peptides (short protein) produced from Budgett’s frog can combat enzymes of ...

Researchers have confirmed that an elusive frog species actually has true teeth on its lower jaw, making it the only one out of 7,000 living frog species to have them today.
