PALAEONTOLOGY

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 dinosaur fossil, which was found in the South of France, is believed to be a primitive cousin of Iguanodon and has been named Matheronodon provincialis.

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.

The salamander has an incredible level of detail preserved, including its spinal cord, gut, muscle and glands. Its last meal of a frog is also still visible in its stomach.

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.

A 12,000-year-old skeleton was found among sabre-toothed cats and giant ground sloths.
