Experts have uncovered the earliest known example of a fish with extra teeth deep inside its mouth—a 310-million-year-old fossilized ray-finned fish that evolved a unique way of devouring prey.

A trade-off between tooth size and jaw mobility has restricted fish evolution, Nick Peoples at the University of California Davis, US, and colleagues report in the open-access journal PLOS Biology.

A research team led by Profs. ZHU Min, LU Jing, and ZHU You'an from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences published two back-to-back ...

Researchers in Alberta uncovered a fossil fish that rewrites the evolutionary history of otophysans, which today dominate freshwater ecosystems. The new species, Acronichthys maccognoi, shows early ...

Scientists studied how the sea creatures, also known as chimaeras or ghost sharks, ended up with one of evolution’s most bizarre appendages. By Jack Tamisiea Life in the ocean’s dark depths can be ...

It’s not just humans who suffer from leading one another astray. So do fish, flies and even bacteria. By Carl Zimmer Earlier this year, the National Academies of Sciences, Engineering and Medicine ...
