Information stored by a geologist's daughter contained data that helped determine the makers of a series of dinosaur tracks found on a cave ceiling in Australia.
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
The shark was likely similar in size to great whites, which grow to an average of around 15 feet.
Computer simulations suggest Neanderthals were already on the brink of extinction and had been for hundreds of thousands of years when demographic fluctuations and inbreeding pushed them over the edge.
In theory, the ancient shark could have grown up to a staggering 22 feet in length, according to researchers.
New discoveries in Bavaria of an ape with "orangutan arms" but human-like legs has the science community excited about connecting the dots of evolution between great apes and humans.
A recently published study describes the fossilized remains of a surprising assemblage of creatures from the Late Jurassic period, including the skull and teeth fragments from a large pliosaurus.
The latest find is surprising because shark skeletons are made of cartilage—a rubbery tissue that doesn't preserve as well as bone.
The dinosaur could bite with about three times the force of large crocodiles or great white sharks.
Up until now, palaeontologists have faced a major problem when it comes to working out what these ancient hominids would have looked like. Now, using DNA methylation, scientists have been able to bring them back to life.
"The new species is one of the largest fossil penguins described so far and one of the very few giant penguins," said researcher Gerald Mayr.
The parrot may have grown to just over 1 meter (3.3 feet) in height and weighed around 15 pounds, according to researchers.
The origin of avian flight has long-puzzled scientists.
The fossils are 15 million years older than any others belonging to the tyrannosauroid family that have been found in North America.
"You can clearly see the texture of the skin and scales, as well as four-toed claw marks, which are extremely rare," one scientist said.
The clutch of babies were likely still inside their eggs.
Does the foot-long fragment come from a mammoth or a mastodon?
"I was immediately excited, it was just perfect, and I knew it was an important find that needed to be shared with people."
It's been 25 years since the release of "Jurassic Park," and our understanding of dinosaurs has evolved considerably. Paleontologists describe new discoveries and technology enabling a better understanding of dinosaurs since "Jurassic Park" came out in 1993.
