DINOSAURS

Potentially groundbreaking results are to be revealed in the BBC2 documentary The Day the Dinosaurs Died.

Enteroccoci emerged with the first animals that crawled on land some 450 million years ago.

The new discovery indicates that microbial life existed in hot springs far earlier than previously known.

The Baby Louie fossil was discovered more than two decades ago in China.

The dinosaur had extraordinarily tiny arms.

The discovery shows that advanced aerodynamic feathers evolved much earlier than thought.

The dinosaur relative Teleocrater had features in common with crocodilians, dinosaurs and birds.

Scientists have discovered evidence of fault displacement linked to the end-Cretaceous asteroid impact.

The fossil is the oldest known member of the semi-aquatic phytosaurs.

Comparisons of fossil skulls with modern birds and crocodilians showed that the tyrannosaur probably had a very sensitive face.

The tracks had been known for decades but no one had ever investigated them in depth.

Drone mapping of dinosaurs' tracks is expected to revolutionise the way researchers investigate dinosaurs.

Another look at the evolutionary history of dinosaurs resolves a long-standing puzzle about birds' earliest ancestors.

The discovery was made by scientists at the Swedish Museum of Natural History.

The species, Anchiornis, already had drumstick-shaped legs and bird-like footpads.

The find is the first in its group – which includes dinosaurs – to have given birth to live young.

Mass eruption at one of the world's biggest volcanic features contributed to extinction of the dinosaurs.

Haematite made from dinosaur blood acted as an antioxidant to preserve the protein collagen, palaeontologists say.

The pterosaur Hatzegopteryx had a thick stocky neck that allowed it to eat very large prey.

Many of the specimens found at the site are incredibly rare, with soft body parts preserved including bones.

The newly discovered species lived alongside dinosaurs at Egg Mountain in Montana, US.
