The word “dinosaur” is a term coined in 1842 by English paleontologist Richard Owen, and it means “terrible lizard.” The name was chosen to emphasize the awe-inspiring size of these creatures. Dinosaurs were reptiles that lived on Earth from about 230 million years ago until around 65 million years ago. They were the dominant terrestrial animals of their time, and they ranged in size from tiny hummingbirds to behemoths over 100 feet long!
Dinosaurs are divided into two major groups: Saurischia (lizard hips) or Ornithischia (bird hips). In each group there are several subgroups based primarily on the hip structure and how many fingers did it have?

Saurischia vs Ornithischia
classification has been a source of much argument among paleontologists, and there’s not just one answer to the question “what is a dinosaur?” There are many different opinions on what makes something a dinosaur! Some people say that it must be bipedal with large hind limbs while others will include anything from toothless living reptiles to those who were once believed extinct but have since come back into existence like birds. The word “dinosaur” means terrible lizard so in this sense any animal fitting these requirements can at least be said to share some similarities with dinosaurs even if they’re not technically classified as such
Dinosaurs are large, typically terrestrial (land-living) vertebrate animals that inhabit the Earth’s landmasses. They can be classified into two groups: Saurischia and Ornithischia based on how their hips functioned. In modern science, ichthyology is a discipline incorporating various aspects of fish biology that includes biostratigraphy to reconstruct evolutionary history through fossil study as well as analysis of present day organisms for information about evolution within species or between different on
Dinosaurs have been a source of fascination and curiosity for centuries. With the recent release of Jurassic World, these creatures continue to fascinate us with their physical appearance, prehistoric history, and scientific classification.
The word “dinosaur” is derived from two Greek words: demos meaning terrible or awe-inspiring and sauros meaning lizard or reptile. The term was coined by Professor Sir Richard Owen in 1842 as a means to classify fossilized remains that he had uncovered while working at Dudley Castle in England during his time as superintendent there; this name would eventually be adopted into common use among scholars ́and scientists worldwide. This group of animals first appeared on Earth approximately 230 million years ago (an estimate based
what is the first dinosaur ever created called?
Tyrannosaurus Rex, Triceratops, Brontosaurus, Stegosaurus. They were all created by John Hammond’s company InGen in Costa Rica. But they didn’t have to create them because they had already been on Earth for some time before then. The T-Rex has killed at least 12 people and eats about 50 pounds a day! There are currently over 600 different species of living animals that fall under the classification “Dinosauria” with new ones being found every year as we explore more parts of the world where fossilized remains can be dug up from the ground.

how many types of dinosaurs are there?
there are over 600 different species of living animals that fall under the classification “Dinosauria” with new ones being found every year as we explore more parts of the world where fossilized remains can be dug up from the ground. The T-Rex has killed at least 12 people and eats about 50 pounds a day! There is only one living type of dinosaur on Earth at the present time, and it’s called a Tuatara which is a lizard-like animal that lives around New Zealand. It lays eggs rather than giving birth to baby lizards through its body or mouth because it evolved separately from other reptiles millions of years ago.
Dinosaurs are a diverse group of reptiles that lived from the Triassic period to about 65.45 million years ago, whose fossils have been discovered on every continent except Antarctica. They were all restricted in their fossil distribution by continental plates and oceans dividing up Earth’s landmasses before dinosaurs evolved into being, but after they appeared, it seems likely that most regions had at least one species of dinosaurs inhabiting it. The original meaning of “dinosaur” is uncertain because there was no such word when these creatures first started becoming well-known; however, we can assume that “dinosaur” comes from the Greek words deinos (meaning terrible or awe-inspiring) and sauros (referring to lizards).
