Dinosaurs

As if Komodo dragons didn't seem ferocious enough already, scientists have now discovered that the reptiles tear through flesh using a coating of iron on their teeth. It is now believed that dinosaurs such as T. rex may have been similarly endowed.

How do we separate the movie myths of Tyrannosaurus rex from the actual animal? The Victoria the T-rex exhibition sets the record straight with recent discoveries about what T-rex looked and sounded like, how it sensed the world, and how it hunted.

A never-before-seen species of horned, herbivorous dinosaur, a predecessor of the Triceratops, has been unveiled at the Natural History Museum of Utah. And its showy, distinctive headgear has earned it a name reminiscent of a god.

A single vertebra dug out of a rock in a stream below a New Zealand mountain in 1978 has been found to have belonged to the oldest sea reptile in southern waters, where no record of these huge beasts had existed. It dates back 246 million years.

While we don't like to talk ill of the dead, new analysis has called into question the intelligence of the king of the dinosaurs. It upends last year's findings that likened the cognitive skills of the Tyrannosaurus rex to that of a primate.

The six-foot-tall raptors in the Jurassic Park movies were terrifying enough, but now scientists have described a giant new raptor species whose legs alone were that tall.

A newly described species of marine reptile could be the largest to ever swim the world’s oceans. The “giant fish lizard” lived more than 200 million years ago, and may give the blue whale a run for its money, size-wise.

Scientists have long puzzled over why some dinosaurs had feathers and wings long before they evolved the ability of flight. Experiments with a robot dinosaur may now have revealed the answer – they used them for hunting.

If T. rex is too mainstream, discerning 10-year-olds may now have a new answer when asked their favorite dinosaur – Tyrannosaurus mcraeensis. The newly identified species appears to be more primitive than its famous cousin, but just as big and scary.

With rapidly advancing techniques to assess fossils, we've never been in a better position to piece together Earth's early days. While there are still plenty of mysteries dating back millions of years, in 2023 we solved a few – and discovered even more.

The debate rages on about the identity of fossils of small tyrannosaurs. A new study claims to have found evidence that a mini tyrannosaur species stomped around alongside its famous, giant cousin – but other scientists aren’t convinced.

Still prized at the dinner table today, it appears the drumstick was just as popular with tyrannosaur kids 75 million years ago. A fascinating find in a dinosaur's stomach offers clues as to why these giant predators became the most successful on Earth.
