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.

Huge species was as big as a wolf and is thought to be the largest otter to have ever lived.

The big chill that followed the impact appears to have played a bigger role in dinosaur extinction than we thought.

Bite marks indicate Carcharocles megalodon was feeding on relatively small prey before they disappeared.

Mysterious ghost sharks share features with prehistoric symmoriiform sharks

Dinosaurs were lumbered with an evolutionary 'dead man's hand' that birds escaped.

These ferocious baby dinosaurs' teeth all fell out as they turned into adults.

Dinosaurs became extremely diverse for three main reasons: specialisation, localisation, and speciation.

Size variations within a species or genus was very large, which may have made them more resilient to natural disasters.

The fossil suggests that a group of feathered dinosaurs was thriving right before the mass extinction.

The proteins show strong similarities to those found in the claw sheaths of birds living today.

The earliest dinosaurs may have walked the Earth 20 million years earlier than we thought.

Discovery could mean dinosaurs had much bigger brains than they are given credit for.

Palaeontologists have been using a method that turns their results into nonsense.

A fossil shows that parrots like those alive today were in northern Asia millions of years ago.

Scientists say microbial life soon returned to the site of an asteroid impact that wiped out 75% of all life.

T-Rex and other large theropods that grew quickly in size often displayed crests or horns.

The Chinese Psittacosaurus could disguise itself from predators.
