Dinosaurs

Newly found 66-million-year-old fossilized ripples support a post-impact tidal-wave scenario.

"It was surprising, and I didn't really understand the impact of it in the beginning," said the woman who found the fossil while visiting her son on the dig.

However, the original film lacked attempts to convert the dinosaurs to Christianity.

Researchers estimate that the species could have reached 25-40 meters (82-131 feet) in length.

The paleontologists who made the find believe that it could take years to exhume the remains completely.

The fossil of an armored shark found on the World Heritage Site of the Jurassic Coast of Dorset, England is of a "news species," scientists named it Durnonovariaodus maiseyi. The extremely rare fossil is about 150 million years old.

The creature has been identified as a type of hadrosaur, but it is unlike any others in that category.

Because we also had sediment that the fossil was found in, we were able to use chemicals to date the sediment and determine that this dinosaur is from the later Crustacean Period and is roughly 70 million years old.

This was a bumper year for breakthroughs in every scientific field, including astronomy and physics.

"Diagnosis of aggressive cancer like this in dinosaurs has been elusive," said researcher Mark Crowther.

The reptile is an early member of the animal group Ornithodira to which both dinosaurs and pterosaurs belong.

Latest study supports the idea that the asteroid impact 66 million years ago was the main driver of dinosaur extinction, not intense volcanic activity as some have suggested.

Many giant dinosaur specimens are very incomplete, which makes it difficult to produce reliable body mass estimates.

The latest findings also help to shed new light on other sites in South Korea where scientists have previously found footprints that were originally thought to belong to giant flying reptiles.

Owen and Ethan wore velociraptor costumes to meet their grandmother at the airport, who suited up as a T-Rex.

"The finding of the actual preserved stomach contents from a dinosaur is extraordinarily rare," said researcher Jim Basinger.

The largest of these prehistoric species was 10 times the length of anchovies living today.

A new Spinosaurus skeleton proves one of the largest dinosaur predators ever discovered lived a largely aquatic lifestyle, opening up a new understanding of dinosaur's place in the ancient world and overturning old dogmas.

Researchers reviewed a group of fossils from an area of the Moroccan Sahara, which includes a host of large dinosaurs, pterosaurs, crocodilians, and other animals.

Scientists say the environmental changes that took place in the end-Triassic extinction event could be similar to what is predicted for the near future.

Preserved roots, pollen, and spores from the forest were found in an ice core taken from near the Pine Island and Thwaites glaciers in West Antarctica

The extinct animal may reveal how modern birds survived the asteroid that wiped out large dinosaurs.

Researchers have found around 50 footprints at two sites on the island.

The animal is one of the oldest tyrannosaur species ever discovered in North America.

"Thalattosaurs were among the first groups of land-dwelling reptiles to readapt to life in the ocean," Neil Kelley, an author of the study from Vanderbilt University, said in a statement.

The discovery provides new insights into hunting behavior of these 150 million-year-old flying reptiles

'Jurassic World 3' director Colin Trevorrow confirmed that a social media thread successfully guessed the full title of the upcoming sequel to 'Jurassic World: Fallen Kingdom.'

The footprints are dated to a time when a major mass extinction event devastated life on Earth.

Researchers say the newly identified specimen indicates that pterosaurs were a more diverse group than previously thought.

Cretodus houghtonorum lived during the Late Cretaceous period, a time when a huge waterway divided North America.
