Paul Callistus Sereno (born October 11, 1957) is a professor of paleontology at the University of Chicago who has discovered several new dinosaur species on several continents, including at sites in Inner Mongolia, Argentina, Morocco and Niger. [1]
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]
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 ...
Researchers found undigested remains of food, plants and prey, in the samples of fossilised faeces, providing clues about the role played by dinosaurs in the ecosystem around 200 million years ago.
In 2015, an independent group of scientists reported that they had found a way to turn the beaks of chicken embryos back into dinosaur-like snouts, by reverse genetic engineering, [36] and University of Chile geneticists have produced embryos with dinosaur-like leg and foot anatomy including the fibula full-length and reaching the ankle.

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.
