John Harold Ostrom (February 18, 1928 – July 16, 2005) was an American paleontologist who revolutionized the modern understanding of dinosaurs. [1] Ostrom's work inspired what his pupil Robert T. Bakker has termed a "dinosaur renaissance".
He is the discoverer of the dinosaur fossil Dakota, a fossilized mummified hadrosaur. He has done significant research on the evolution of turtles and on the rise of mammals after the extinction of the dinosaurs. Lyson was born and raised in Marmarth, North Dakota, a tiny town near the Badlands, an area known for its dinosaur fossils. As a ...
A new analysis of fossil faeces has revealed what the environmental conditions were like at the time dinosaurs started to take over the Earth.. Researchers found undigested remains of food, plants ...
Robert Thomas Bakker (born March 24, 1945) is an American paleontologist who helped reshape modern theories about dinosaurs, particularly by adding support to the theory that some dinosaurs were endothermic (warm-blooded). [2]
Dinosaurs were initially cold-blooded, but global warming 180 million years ago may have triggered the evolution of warm-blooded species, a new study found. Study reveals when the first warm ...
A mass extinction event that brought about the rise of the dinosaurs more than 200 million years ago was believed to be caused by the planet’s warming. Now, scientists at Columbia University say ...
Currie's contributions to the study of dinosaur dentition include helping discover the first known instance of alveolar remodelling in dinosaurs [26] and revealing in a 2020 study that the dentition of Sinraptor bore extreme similarities to that of Allosaurus, further concluding that Sinraptor would likely have actively hunted medium-sized ...
