How do you Paleontologists name and classify dinosaurs?
Some were very much like each other. Others were quite different. Paleontologists name, and classify or group dinosaurs according to the shape of their hip bones, teeth, feet, and other body parts. Most of the Douglass Quarry fossils are part of the long-neck, long-tail, plant-eating group called Sauropods.

“Don” means “tooth” – many species first show up as fossil teeth, and there are many we know only from their teeth. “Raptor” means “thief” – the first species named in this way was Oviraptor, because it was found near a pile of eggs and the paleontologist surmised that perhaps it lived by stealing other dinosaurs’ eggs.
What was before dinosaurs?
The age immediately prior to the dinosaurs was called the Permian. Although there were amphibious reptiles, early versions of the dinosaurs, the dominant life form was the trilobite, visually somewhere between a wood louse and an armadillo. In their heyday there were 15,000 kinds of trilobite.
Are dinosaurs real today?
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
Can dinosaurs come back?
Without access to dinosaur DNA, researchers can’t clone true dinosaurs. New fossils are being uncovered from the ground every day. … In 2020, researchers from the U.S. and China discovered cartilage that they believe contains dinosaur DNA, according to a study published in the journal National Service Review.
