Discover interesting Dinosaurs facts
In 1923, explorer Roy Chapman Andrews found the first dinosaur nest known to science in the Gobi Desert of Mongolia. Before he found the nest, scientists were unsure about how dinosaurs were born.
The heaviest dinosaur was Argentinosaurus at 77 tonnes. It was the equivalent to 17 African Elephants. Argentinosaurus is a double award winner being also the longest dinosaur. It is also the largest land animal to have ever lived.
Tyrannosaurus rex had huge back legs, but its tiny front legs were not much longer than human arms
In 2015, scientists discovered a new dinosaur species. They nicknamed it "Hellboy" because the stubby horns above its eyes looked like the comic book character of the same name.
The smallest dinosaurs that we know of were just 4-feet and weighed less than a chihuahua.
The first dinosaur to be formally named was the Megalosaurus, back in 1824.
The longest dinosaur was Argentinosaurus, which measured over 40 metres, as long as four fire engines. It was part of the Titanosaur group of dinosaurs. Its remains have been found in Argentina, South America.
Some dinosaurs tails were over 45 feet long. Most dinosaurs had long tails that helped them to keep their balance when running.
Rather than being carnivores (meat eaters), the largest dinosaurs such as the Brachiosaurus and Apatosaurus were actually herbivores (plant eaters).
A person who studies dinosaurs is known as a paleontologist.
Dinosaurs are divided into two groups, based on their hip structure – the first one “Saurischia” (lizard-hipped), and the second “Ornithischia” (bird-hipped).
The word dinosaur comes from the Greek language and means ‘terrible lizard’. The word was coined by English paleontologist Richard Owen in 1842 and was meant to refer to Dinosaurs impressive size rather than their scary appearance.
No one knows exactly how long a dinosaur’s lifespan was. Some scientists speculate some dinosaurs lived for as long as 200 years
The tallest plant eater was the Brachiosaurus (Giraffatitan brancai). Its head was up to 39 feet (12 m) off the ground.
The dinosaur with the longest name is Micropachycephalosaurus (“small thick-headed lizard”).
All dinosaurs laid eggs. About 40 kinds of dinosaur eggs have been discovered.
Birds descended from a type of dinosaurs known as theropods.
Some scientists believe that Tyrannosaurus rex may have been able to run as fast as 18 mph (28 km/h). Other scientists believe it could not run at all because it was so big.
Dinosaurs ruled the Earth for over 160 million years, from the Triassic period around 230 million years ago, through the Jurassic period and until the end of the Cretaceous period around 65 million years ago.
Dinosaurs lived on all the continents, including Antarctica.
At present over 700 different species of dinosaurs have been identified and named. However palaeontologists believe that there are many more new and different dinosaur species still to be discovered.
Scientists believe that the event leading to the extinction may have been a massive asteroid impact or huge volcanic activity. Events such as these could have blocked out sunlight and significantly changed the Earth’s ecology.
Back when dinosaurs existed, there used to be volcanoes that were erupting on the moon.
One of the most intelligent dinosaurs was Troodon. It was a hunting dinosaur, about 2 metres long, and had a brain size similar to that of a mammal or bird of today, stereoscopic vision, and grasping hands.
The largest dinosaur eggs were as large as basketballs. The bigger the egg, the thicker the shell. So if the eggs had been larger, dinosaur babies probably would not have been able to get out.
The fastest dinosaur was the Ornithomimus. It could run at a speed of about 43 miles per hour (70 km/h).
