A newly reconstructed fossil face from Ethiopia reveals surprising complexity in early human evolution. By digitally fitting together teeth and fossilized bone fragments, researchers reconstructed a ...

Over 500 million years ago, the Cambrian Period sparked an explosion of skeletal creativity. Salterella, a peculiar fossil, defied conventions by combining two different mineral-building methods.

For over half a billion years, evolution has sculpted the nervous systems of bilaterian animals, equipping them with ...

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 ...

It was a gray morning on the steppes of central Mongolia when paleontologist Tsogtbaatar Chinzorig spotted something glinting on a distant slope. It was not a rock. As he drew closer, he realized he ...

Creepy collector she is not; Cooke's quest for canines, incisors, and molars is driven by a desire to better understand Earth's past. Give this intrepid paleontologist a fossilized tooth, and there's ...

Some of the oldest dinosaurs didn't have hollow bones, suggesting that skeletal air sacs evolved independently in three lineages: long-necked sauropodomorphs, meat-eating theropods and pterosaurs.
