Latest Evolution of dinosaurs Stories
About 150 million years ago, an evolutionarily hybrid creature, a dinosaur on its way to becoming a bird, died in what is now Germany, and become fossilized in limestone.
A recent study by researchers at the University of Bath and Londonâ€™s Natural History Museum has found that scientistsâ€™ knowledge of the evolution of dinosaurs is remarkably complete.
The fossilized skeleton of a small crocodile relative excavated last year at Petrified Forest National Park in Arizona throws a wrench into theories of how and where the dinosaurs arose more than 210 million years ago at the end of the Triassic Period. This suggests that the herbivorous ornithischians and the meat-eating theropods, like Tyrannosaurus rex, did not evolve together in the Late Triassic as many paleontologists thought.

Psittacosaurus, meaning “parrot lizard,” is a genus of ceratopsian dinosaur from the Early Cretaceous Period of what is now Asia (130 to 100 million years ago). It is the most species-rich dinosaur genus with nine to eleven recognized species from fossils found in different regions of modern-day China, Mongolia and Russia. There is also a possible species from Thailand. Psittacosaurus was named by Henry Fairfield Osborn, paleontologist and president of the American Museum of Natural...
Scutellosaurus, meaning "little-shielded lizard," is a genus of herbivorous dinosaur from the Early Jurassic Period of what is now North America (200 to 196 million years ago). It is classified in the sub-order Thyreophora, which include armored dinosaurs. Its closest relative may have been Scelidosaurus, which, unlike the bipedal Scutellosaurus, was mainly quadrupedal. It was one of earliest representatives of Thyreophora. Fossil evidence includes two partial skeletons recovered from...
