Megalodon sharks may have become megapredators by running hot

O. megalodon sharks were warm-blooded megapredators. But colder-blooded great white sharks may have had an evolutionary edge when food sources dwindled.

Paleontology has a ‘parachute science’ problem. Here’s how it plays out in 3 nations

When researchers study fossils from lower-income countries, they often engage in dubious or illegal practices that can stifle science.

New fossils from Patagonia may rewrite the history of duck-billed dinosaurs

New findings are adding a wrinkle to researchers’ understanding of how duck-billed dinosaurs conquered the Cretaceous world.

Paleontology

‘Thunder beast’ fossils show how some mammals might have gotten big

Rhinolike mammals called brontotheres repeatedly evolved into bigger and smaller species, a fossil analysis shows. The bigger ones won out over time.

Paleontology

Newfound bat skeletons are the oldest on record

The newly identified species Icaronycteris gunnelli lived about 52.5 million years ago in what is now Wyoming and looked a lot like modern bats.

Life

T. rex may have had lips like a modern lizard’s

Dinosaurs like Tyrannosaurus have long been portrayed as lipless, but new research suggests this wasn’t so.

Paleontology

310-million-year-old fossil blobs might not be jellyfish after all

An ancient animal called Essexella may have been a type of burrowing sea anemone, a new study proposes.

Paleontology

520-million-year-old animal fossils might not be animals after all

Newly described fossils of Protomelission gatehousei suggest that the species, once thought to be the oldest example of bryozoans, is actually a type of colony-forming algae.

Paleontology

The oldest known pollen-carrying insects lived about 280 million years ago

Pollen stuck to fossils of earwig-like Tillyardembia pushes back the earliest record of potential insect pollinators by about 120 million years.

Paleontology

Insect bites in plant fossils reveal leaves could fold shut millions of years ago

The 252-million-year-old fossil leaves have symmetrical holes, which suggest an insect bit through the leaves when they were folded.

Paleontology

This dinosaur might have used its feet to snag prey in midair like modern hawks

Fossilized toe pads suggest a hawklike hunting style in Microraptor, a dinosaur that some scientists think could hunt while flying.

In the wake of history’s deadliest mass extinction, ocean life may have flourished

Ocean life may have recovered in just a million years after the Permian-Triassic mass extinction, fossils from South China suggest.
