Dinosaurs: News & Pictures of Dinosaur Types

Dinosaurs types are many and varied, from small bird-like creatures to the largest animals ever to walk on Earth. The subject of blockbuster films, history museum exhibits and much more, dinosaurs continue to interest people today after first appearing approximately 230 million years ago. These vertebrate animals dominated the land for more than 160 million years before experiencing a catastrophic extinction at the end of the Cretaceous period 65 million years ago. The first dinosaur was recognized in the 19th century and ever since, dinosaurs have been the source of many questions. What contributed to the rapid extinction of the dinosaur? What do the latest fossil findings reveal about the dinosaur and its way of life? How is the modern bird connected to these prehistoric creatures? Could dinosaurs like Tyrannosaurus Rex and Brontosaurus really be brought back to life with mosquito DNA? Inside you'll find dinosaur news & features, along with plenty of pictures.

Special adaptations to diving and flying show how dinosaurs and birds used their feathers in the Late Cretaceous.
A trove of dinosaur protofeathers and modern bird feathers that have been preserved in amber since the Late Cretaceous offers researchers a unique chance to examine the structure, function and even color of the feathers adorning dinosaurs and early birds.

dinosaur, polar dinosaurs, south pole, southern hemisphere, dino tracks, theropods, bird-like dinosaurs,
The more than 20 polar dinosaur tracks found on the coast of Victoria, Australia, offer researchers a rare glimpse into animal behavior during the last period of pronounced global warming, about 105 million years ago.
ceratopsian dinosaur bones
By analyzing tiny holes in the thigh bones of dinosaurs, researchers were able to gauge their metabolic rate.
dinosaur, meteor, extinction, kt boundary, K-T boundary, turtle, tough turtles, baenid turtles, mammals.
The turtles and their water-loving cousins seem to have survived because of their slow metabolisms, but why did the mammals win out in the end?
This is a Jurassic sauropod.
Body temperatures of sauropods are cooler than would be expected from their size, but not as cool as would be expected from a cold-blooded animal.
