Your kids might be asking you questions like how many dinosaurs were there, what they were called, what happened to them, etc. Read this post as we bring fascinating information about the dinosaurs to keep your children entertained and engaged.
Origin Of The Word “Dinosaur” And What it means?
Sir Richard Owen, a biologist from England, coined the term “dinosaur.” He used this word to classify a large group of animals, “Dinosauria” (1).
The word ’Dinosaur’ was derived from the Greek “deinos,” which means “big and terrible” and “sauros” means “lizard.” Although researchers called them “Big terrible lizards,” dinosaurs are not lizards.
Evolution Of A Dinosaur
Around 350 million years ago, due to natural phenomena, reptiles survived without water. As their bodies evolved, the reptiles changed to the four-legged amphibians. The early reptiles were lizards, snakes, turtles, ancestor mammals, and plesiosaursiXA group of extinct long-necked marine reptiles belonging to the mesozoic era. .
It is believed that some of these reptiles later evolved into dinosaurs called “Archosaurs” and “AvemetatarsaliansiXArchosaurs that are closely related to birds. .”
How Many Types Of Dinosaurs Existed?
More than 700 dinosaur species have been discovered so far. Paleontologists hope to discover more species from the excavation sites.
Megalosaurus, a giant carnivore, roamed the Earth about 169 million years ago. Megalosaurus was nine meters long and three meters tall. One of the first dinosaur fossils ever discovered was of the Megalosaurus. Reverend William Buckland, a geologist, was the first to study the fossil of the dinosaur in 1824 and named it Megalosaurus
All dinosaurs descended from reptiles called ’Archosaurs.’ They came in different shapes and sizes. British paleontologist Harry Seeley classified dinosaurs into two categories – Ornithischia and Saurischia – based on their hip structure.
- Ornithischia: Also known as bird-hipped dinosaurs, Ornithischia were herbivorous. Ornithischia dinosaurs have no known carnivoresiXAnimals that feed on the meat or flesh of other animals. within their group. They walked on all four legs. Triceratops, Iguanodon, and Stegosaurus were well-known dinosaurs from the Ornithischia category. Ornithischia dinosaurs were not precursors to birds.
- Saurischia: Also known as lizard-hipped dinosaurs, Saurischia were carnivores. They were the most feared and violent species that walked on two legs. They had short arms, sharp jaws, and powerful tails. The pubis boneiXA bone situated in the pubic region that constitute the hip bone. in Saurischia dinosaurs, such as T-Rex, faced forward and down.
The top three Saurischian dinosaurs are T-Rex, Allosaurus, and Oviraptor. They were the precursor to the birds, which evolved from the avian dinosaur, who were the only ones to survive the extinction event.
Extinction Of Dinosaurs
For more than 140 million years, the dominance of dinosaurs was unchallenged except by other dinosaurs. But all that changed overnight when the dinosaurs were wiped out. The reason for their extinction is not known. But the most accepted theory is that an asteroid strike that occurred 66 million years ago led to their extinction.

Frequently Asked Questions
1. What can children learn from dinosaurs?
Introducing your children to the lives of dinosaurs can be a great way to teach them how creatures adapt, survive, and sometimes disappear from the environment. Teaching them that we do not know everything about the world yet and are still researching several aspects of nature and science may motivate them to do their own research.
2. Do dinosaurs sleep?
Yes, dinosaurs do sleep. The discovery of the fossil of a dinosaur resting with its head over the forearm and trunk and tail wrapped around its body proves that dinosaurs did sleep.
3. What were the different types of dinosaurs that existed?
Ornithischia and Saurischia are two main groups of dinosaurs based on their bone structures. Tyrannosaurus Rex, Seismosaurus, Mussaurus, Megalosaurus, Triceratops, Iguanodon, Stegosaurus, Allosaurus, Oviraptor, Brachiosaurus, and Spinosaurus were some of the dinosaurs falling under these categories.
4. What are the benefits of teaching kids about dinosaurs?
Teaching children about dinosaurs offers numerous benefits. For instance, learning about dinosaurs’ appearance, behavior, and fossils can spark a child’s inquisitiveness about the natural world and boost critical thinking.
