Dinosaurs

Researchers used iridium - the second most dense metal on Earth - to effectively target and attack cancer cells, boosting hopes for new treatments.

Researchers estimate that the fearsome predator had a wingspan of up to 36 feet and may have stood as tall as a giraffe.

The 5.5 metre-long Jurassic ichthyosaur is believed to be one of the most complete skeletons of its kind ever found in India.

The colour patterns of dinosaurs resemble those seen in many modern animals, helping them to avoid detection by both predators and prey.

The dinosaur footprints measured 57cm long, suggesting it was was around 30ft tall - around four times the size of a fully-grown lion. It roamed what is now southern Africa 200 million years ago.

Dinosaurs have acquired a bad rep for being solitary lone rangers with bad tempers, but a new discovery reveals that they may have been group sleepers.

A remarkably well-preserved fossilised skeleton of the tyrannosaur from the Late Cretaceous Period was found in southern Utah.

Over millions of years, large herbivores such as certain dinosaurs may have played a crucial role in dispersing vital nutrients across continents.

Fossils dismissed in the 1970s as a common species have now been identified as a new kind of ichthyosaur. Researchers made the discovery after exposing evidence of fakery.

A fossil belonging to the 'Melksham Monster' had been sitting in the archives of the Natural History Museum for nearly 150 years before being identified as a new species.

The meal could have been the ichthyosaur's first and last. Let's hope it was good.

Researchers think they have identified the evolutionary process behind this transformation.

The unusual behaviour may have been linked to sexual activity.

The fearsome crocodile lived among the dinosaurs during the Cretaceous Period.

Scientists found traces of complex animals which pre-date the oldest known fossils.

The skull shape was closely related to the size and shape of the brain within.

Soriatitan golmayensis is thought to have lived between 130 and 138 million years ago.

The marine reptile is the earliest of its kind to be discovered.

It went dark for at least two years after the asteroid hit 66 million years ago.

Chilesaurus has baffled scientists since its discovery in 2015.

They could glide between trees above the dinosaurs that roamed the ground.

The 110-million-year-old fossil is one of the best-preserved dinosaurs ever found.

The last record of the plant on the western side of the Atlantic was a 66 million years old fossil in Argentina.

Flowers evolved during the era of the dinosaurs.

The large crest was probably a mark to impress potential mates.

A massive volcanic eruption is thought to have triggered suffocation in the shallow oceans.

The pelvis bone is now thought to have been that of a pterosaur.

Was it the worst ever case of toothache, or marks from a deadly battle?

The reptile's teeth were 15 cm long from root to tip.

Scientists have come up with a new tree of life for frogs and a new timeline for their evolution.
