"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.
The swarm of male shrimp were killed in a "mass mortality" event during the time of the dinosaurs.
248 million-year-old fossils discovered in Russia almost 60 years ago re-examined by scientists.
While dinosaur fossils have been found across Alaska, there are very few records of these ancient animals in the Alaskan Peninsula.
The dinosaur could bite with about three times the force of large crocodiles or great white sharks.
Two new species of dinosaurs are introduced to the "Jurassic Park" series in the new Colin Trevorrow-directed short film "Battle at Big Rock."
For decades, scientists thought that the two holes in the roof of the dinosaur's skull aided jaw movement.
The newly identified dinosaur, named Aquilarhinus palimentus, represents an entirely new genus, or group of species.
