About 360 million years ago, a huge armored fish patrolled a shallow sea that once covered what is now Cleveland. This animal, known as Dunkleosteus terrelli, has long held a place among the most ...

Researchers have linked the development of the human jaw to a 423-million-year-old armoured fish that skulked the bottom of the oceans. Paleontologists from China and Sweden said Thursday that our ...

Neural crest cells are involved in the development of osteoderms (like those in crocodiles) and the plastrons of turtles, so it seems likely. Some sources say they're behind virtually all ...

(CNN) — The sensitive interior of human teeth might have originated from a seemingly unlikely place: sensory tissue in fish that were swimming in Earth’s oceans 465 million years ago. While our teeth ...
