Horses lived in the Americas for millions of years – new research helps paleontologists understand the fossils we’ve found and those that are missing from the record

Horse fossils are abundant and widespread across North America. Scientists often use their long history to illustrate how species evolve in response to a changing environment.

Fossil teeth reveal how brains developed in utero over millions of years of human evolution – new research

Using a new equation based on today’s primates, scientists can take a few molar teeth from an extinct fossil species and reconstruct exactly how fast their offspring grew during gestation.

Megalodon sharks ruled the oceans millions of years ago – new analyses of giant fossilized teeth are helping scientists unravel the mystery of their extinction

Megalodon, the world’s largest known shark species, swam the oceans long before humans existed. Its teeth are all that’s left, and they tell a story of an apex predator that vanished.
The Grotte Mandrin rock shelter saw repeated use by Neanderthals and modern humans over millennia. Ludovic Slimak

New research suggests modern humans lived in Europe 10,000 years earlier than previously thought, in Neanderthal territories

Stone artifacts and a fossil tooth point to Homo sapiens living at Grotte Mandrin 54,000 years ago, at a time when Neanderthals were still living in Europe.

Teeth can reveal a lot about diversity when they are reasonably well-preserved.
