[D385]Dinosaur Facts For Children
by Shagufta Khan, Sha

The dinosaurs have always thrilled humans and held them spell bound for their variety of species from small to huge and gigantic dinosaurs. They are no more in existence but their presence is still felt in the museums, books and films. The dinosaurs first appeared on this earth around 230 million years ago and showed their existence for complete 160 million years. Some dinosaurs were herbivorous whereas some were carnivorous.
The dinosaurs existed in Triassic, Jurassic and Cretaceous period. The late Triassic period witnessed some genera of dinosaurs like Coeophysis with double hinged lower jaw and small sharp teeth showing its carnivorous nature. The one who came in the herbivorous category was the Plateosaurus with nine meter long and four meter tall body weighing about 4 tones and there were others like melanorosaurs, Anchisaur, prosauropod and early sauropod
But the end of this period witnessed mass extinction; about 95% species disappeared from this earth and with this went the early dinosaurs. The late Triassic period marked the beginning of the “age of dinosaurs" which further developed in the Jurassic Period. The Jurassic period lasted for 30 million years where reptiles were the dominant figures and so this age is known as “The age Of Dinosaurs." The dinosaurs existed during this period were different from those of other periods.

Dinosaurs evolved during this period. The largest herbivorous and carnivorous dinosaurs came into being during Jurassic period. The biggest meat eater of the Jurassic was the Allosaurus better known as the different lizard. It was about 40 feet long and many dinosaurs of this period were scared of him. Another colossal size dinosaur was a herbivore known as Apatosaurus but which was formerly known as Brontosaurus. It measured between 70 to 90 feet but its head was too small as compared to the enormous body. It is really shocking to know that on one side we had huge dinosaurs but on the other side their existed the smallest dinosaur of the size of a chicken called Compsognathus. Dinosaurs of different features and characteristics were found in this period.
Even the early known bird Archeoptyx had similar characteristics of a dinosaur. The Diplodocus dinosaur was 90 feet long and was one of the longest land animals. The long neck of Mamenchisaurus dinosaur about 46 feet was its distinctive feature which made it different from other dinosaurs. Stegosaurus existed in the late Jurassic period had a gargantuan body of three ton but the brain of the size of walnut.

The third period was the Cretaceous period when the growth of the dinosaurs was full blown. This was the time when some unique dinosaurs were there on the earth. Triceratops, Tyrannosaurus rex, Parasaurolophus, Carnotaurus Anatosaurus, Monoclonius, Tarbosaurus Gallimimus Corythosaurus, Albertosaurus, were some the dinosaurs of cretaceous Period. They were the one who came out with more distinct features and some of the exceptional characteristics which made them different from those of other period. But with the end of this period ended the existence of dinosaurs from this earth altogether.


Many of us, especially kids, are very curious about dinosaurs. We are always eager to know more about this life form that roamed the earth thousands of years ago. Here are some interesting facts about dinosaurs:

The Largest Dinosaur

According to studies from complete skeletons, the Brachiosaurus is the largest or heaviest and tallest dinosaur. They are about 40 feet tall and approximately 70 to 80 tons in weight. Further studies about other dinosaurs like the Seismosaurus, Supersaurus, Ultrasaurus and Argentinosaurus are suggesting that the Brachiosaurus is not really the largest dinosaur. However, merely partial skeletons of these dinosaurs were discovered, making scientists uncertain if these are new species or they are also larger Brachiosaurus.

The Estimated Age of Dinosaurs

If scientists will just base their calculations on fossil records, the age of dinosaurs cannot be guaranteed. Although there were studies on their teeth's growth rings, these were constantly replaced throughout the dinosaur's lifespan. Thus, when compared to modern large mammals and reptiles, scientists estimated that dinosaurs could have lived for about 50 up to 150 years.

The Smallest Dinosaur

Paleontologists noted that the smallest dinosaur was the Compsognathus. It is even about the same size as a chicken. An adult Compsognathus can reach 2 feet in length, more attributed to its thin, long tail.

The Smartest Dinosaur

The Troodon had the largest brain out of all the species. This is in relation to its actual body size. This is why they are thought as the most intelligent amongst other dinosaurs. In fact, most paleontologists regard them as smarter than an ostrich, making it smarter than any living reptile on Earth now.

The Toughest Dinosaur

Contrary to belief that the toughest dinosaur was the Tyrannosaurus Rex, it is the Deinonychus. This is because the T-Rex is more like a scavenger than a ferocious hunter. This made the Deinonychus the meanest ad toughest dinosaur. It is merely 2.7 meter long, 1.5 meters tall and it weighs just like an average man. Despite their small size, they are noted as “the most extraordinary predators of all time”. Due to its large serrated teeth, keen eyesight, great agility, grasping hands and sickle-shaped 5-inch long claws on every hind's foot, this dinosaur variety is a very ferocious enemy.

The Size of Dinosaur Eggs

Despite the size of dinosaurs, their eggs are quite small. In fact, the gigantic Sauropod's eggs are no bigger than volleyballs. One reason is the fact that a bigger egg entails thicker shells so that it will not collapse. A very thick shell can actually pose 2 big problems. The 1st problem is that it is too thick for the oxygen to permeate. This means, the embryos will not be able to breathe. The 2nd problem would be the fact that the shell will be too thick to be pushed by the hatchlings.

The Fastest Dinosaur

The Galliminus which can travel about 35 mi per hour is considered as the fastest dinosaur. The Coelophysis ranks second at an estimated 25 mi per hour. The third in ranking is the T-Rex at 15 mi per hour.

The Strangest Dinosaur

The Ancient Wing or the Archaeopteryx is a small creature with feathers. It is similar to a chicken but it can fly. It is actually the 1st known bird, showcasing how birds are descendants of dinosaurs.

The Number of Dinosaur Types

At current, paleontologists and scientists note that there are about 440 types of dinosaurs that existed.

The Voices of Dinosaurs

Even if no one actually heard the voice of a dinosaur, many scientists guess that the T-Rex had a raspy and deep voice, the Hadrisaur had a voice like a honking 5-ton goose and the Apatosaurus had a voice similar to a herd of snorting horses.

Dinosaur Names

The names of dinosaurs are mostly a combination of Greek or Latin root words. Their names actually describe them. A good example would be the Triceratops which means “three-horned face.” These names also describe the place of their discovery or to recognize learning institutions. A good example is the Arctosaurus whose remains were found along the Arctic Circle. The Yaleosaurus was actually named after the Yale University.
