Early dinosaurs may have laid soft-shelled eggs

Scientists for the first time have turned up evidence of fossils from soft-shelled dinosaur eggs. This has scientists rethinking how dinosaur eggs evolved.

Fossils

These crocodile ancestors lived a two-legged life

A set of 106-million year old footprints show a crocodile relative appears to have walked on two legs.

Fossils

Tube-dwelling sea creatures may be oldest known parasites

Fossils

The challenge of dinosaur hunting in deep caves

Spelunkers aren’t the only people to find caves interesting. So do paleontologists. Though getting to work may be harrowing, they find it’s worth it.

During this time from about 200 million to 145 million years ago, dinosaurs reigned and many animals evolved, including birds and some early mammals.
