The remains of the earliest dinosaurs may lie undiscovered in the Amazon and other equatorial regions of South America and Africa, suggests a new study.

The fossilized neck bone of a flying reptile unearthed in Canada shows tell-tale signs of being bitten by a crocodile-like creature 76 million years ago, according to a new study.

A newly described dinosaur whose fossils were recently uncovered is challenging the existing narrative, with evidence that the reptiles were present in the northern hemisphere millions of years earlier than previously known.

While volcanism caused a temporary cold period, the effects had already worn off thousands of years before the meteorite, the ultimate cause of the dinosaur extinction event, impacted.

Research has revealed that several groups of meat-eating dinosaur stalked the Bexhill-on-Sea region of coastal East Sussex 135 million years ago.

Researchers have been able to identify undigested food remains, plants and prey in the fossilized feces of dinosaurs. These analyses of hundreds of samples provide clues about the role dinosaurs played in the ecosystem around 200 million years ago.

Scientists have presented results on the acoustic characteristics of a physical model of the Parasaurolophus' crest. They created a physical setup made of tubes to represent a mathematical model that will allow researchers to discover what was happening acoustically inside the crest. The physical model, inspired by resonance chambers, was suspended by cotton threads and excited by a small speaker, and a microphone was used to collect frequency data.

Wings may be the obvious choice when studying the connection between dinosaurs and birds, but a pair of paleontologists prefer drumsticks. That part of the leg, they say, is where fibular reduction among some dinosaurs tens of millions of years ago helped make it possible for peacocks to strut, penguins to waddle, and turkeys to trot.

A 'one of a kind' fossil discovery could transform our understanding of how the unique brains and intelligence of modern birds evolved, one of the most enduring mysteries of vertebrate evolution.

Extraordinarily well preserved fossils of feathered dinosaurs and other creatures got that way after being frozen in time by by volcanic eruptions, researchers have long suggested. Not so fast, says a new study.

The new mammal lived in Colorado 70 to 75 million years ago -- a time when a vast inland sea covered large portions of the state, and animals like sharks, turtles and giant crocodiles abounded.

Chemists offer a new explanation for how collagen in dinosaur bones may have survived millions of years: An atomic-level interaction prevents its bonds from being broken down by water.

An international team of paleontologists has found matching sets of Early Cretaceous dinosaur footprints on what are now two different continents.

Scientists have discovered that the serrated edges of Komodo dragons' teeth are tipped with iron. The study gives new insight into how Komodo dragons keep their teeth razor-sharp and may provide clues to how dinosaurs like Tyrannosaurus rex killed and ate their prey.

A study looks at the maximum possible sizes of dinosaurs, using the carnivore, Tyrannosaurus rex, as an example. Using computer modelling, experts produced estimates that T. Rex might have been 70% heavier than what the fossil evidence suggests.

New research has examined the fossil record going back 66 million years and tracked changes to mammalian ecosystems and species diversity on the North American continent.

The surprising discovery of a new species of extinct crocodile relative from the Triassic Favret Formation of Nevada, USA, rewrites the story of life along the coasts during the first act of the Age of Dinosaurs. The new species Benggwigwishingasuchus eremicarminis reveals that while giant ichthyosaurs ruled the oceans, the ancient crocodile kin known as pseudosuchian archosaurs ruled the shores across the Middle Triassic globe between 247.2 and 237 million years ago.

The most complete dinosaur discovered in the UK in the last 100 years, with a pubic hip bone the size of a 'dinner plate', has been described in a new article.

A newly discovered ancestor of Thescelosaurus shows evidence that these animals spent at least part of their time in underground burrows. The new species contributes to a fuller understanding of life during the mid-Cretaceous -- both above and below ground.

Scientists discovered the oldest fossil grapes in the Western Hemisphere, which help show how after the death of the dinosaurs, grapes spread across the world.
