1) The longest dinosaur: The longest dinosaur ever found is Argentinosaurus. Its length is more than 40 meters, which is equal to 4 fire engines. They belong to the Titanosaur group. They were found in Argentina, North America.
2) The heaviest dinosaur: The heaviest dinosaur discovered so far is Argentinosaurus, with an average weight of about 77 tons. It is the equivalent of the current 17 African elephants. This is the longest dino title ever. It is the largest terrestrial animal ever found.
3) The smallest dinosaur eggs: Dinosaur eggs come in all shapes and sizes. These are usually oval or round and about 30 cm long, about the size of a rugby ball. The smallest dino egg found is only 3 cm long. Once these eggs turn into fossils, they harden like rocks and take on a shape of their own.
4) The smallest dinosaur: The smallest, most complete dinosaur fossil ever found is a tiny bird-like herbivorous animal, such as Lesothosaurus. Its size is just like a baby chicken. Examples of smaller fossils have been found, but they are all baby dinosaurs.
However, the smallest dinosaur fossil, Oculudentavis khaungraae, has recently been found in a Cretaceous rain forest in northern Myanmar. It is only 1.5 cm long. Oculudentavis means "eye tooth bird".
5) The most intelligent dinosaurs: Troodon is one of the most intelligent dinosaurs. It is a predatory dinosaur, which is 2 meters long. Their brain size is almost similar to the brain of a current mammal or bird. They had stereoscopic vision and strong hands.
6) The most useless dinosaur: Stegosaurus had a brain the size of a walnut, only 3 cm long, and weighed 75 grams. However, comparing the size of the brain with the size of the body, it can be said that sauropodomorphs, such as Plateosaurus, were the most stupid, useless dinosaurs.
7) The longest dinosaur: The longest dinosaur was the Brachiosaurid of the group of sauropods. Their forelegs were longer than their hind legs, giving them a giraffe-like structure. The most well-known dinosaurs in this group, the Brachiosaurus, were about 13 m long.
8) Fastest dinosaurs: The fastest dinosaurs are ostrich mimic ornithomimids, such as Dromiceiomimus, who probably ran at 60 km / h.
9) The oldest dinosaurs: The oldest dinosaurs are thought to be the Saltopus. These were tiny carnivores who lived on Earth 245 million years ago. Remains of these dinosaurs were found only in Scotland, so the UK holds the key to the mystery of the origin of these dinosaurs.
9) Longest-named dinosaur: The largest dinosaur is Micropachycephalosaurus, meaning "tiny thick-headed reptile". Their fossils were found in China, and in 1978 the Chinese paleontologist named Dong
10) The most ferocious dinosaur: Tyrannosaurus Rex may seem to be the most ferocious dinosaur, but overall cunning, observation, and tool layout make it clear that Utahraptor was the ferocious dinosaur.
11) Longest Pterosaur: The 13 meter wingspan Quetzalocoatlus was probably the longest Pterosaur and the longest flying creature of all time. Despite its size, it did not weigh more than 100 kilograms. Pterosaurs were not dinosaurs.
12) The first dinosaur to be named: The first dinosaur to be named was Megalosaurus.Reverend William Buckland named it in 1824. Meagalosaurus means "large reptile". They were 9 meters long and 3 meters long.
