Some fun facts on Dinosaur
The smallest fully-grown fossil dinosaur is the little bird-hipped plant-eater like Lesothosaurus, which was only the size of a chicken. Smaller fossilised examples have been found, but these are of baby dinosaurs.
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.
The heaviest one was Argentinosaurus at 77 tonnes. It was the equivalent to 17 African Elephants. Argentinosaurus is a double award winner being also the longest. It is also the largest land animal to have ever lived.
The tallest dinosaurs were the Brachiosaurid group of Sauropods. Their front legs were longer than the rear legs giving them a giraffe-like stance. This combined with their extremely long necks, which were held vertically, meant they could browse off the tallest trees. Brachiosaurus – the most well-known of the group – was 13 metres tall. Sauroposeidon was massive and probably grew to 18.5 metres tall making it the tallest among all.
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.
Stegosaurus had a brain the size of a walnut – only 3 centimetres long and weighing 75 grams. However, comparing brain size to body size sauropodomorphs, like Plateosaurus, were probably one of the dumbest dinosaurs.
The Fastest Running
The speediest were the ostrich mimic ornithomimids, such as Dromiceiomimus, which could probably run at speeds of up to 60 kilometres per hour.
The Oldest Dinosaur
The oldest known dinosaur is Saltopus. It was a small carnivore that lived 245 million years ago. Remains of this dinosaur have only been found in Scotland, so the UK might hold the key to the origin of dinosaurs.
The Fiercest Dinosaur
Tyrannosaurus rex looked the most ferocious of all, but in terms of overall cunning, determination and its array of vicious weapons it was Utahraptor that was probably the fiercest of all. Utahraptor measured about 7 metres, and was a very powerful, agile and intelligent predator.
The First Dinosaur to be Named
The first dinosaur to be named was Megalosaurus. It was named in 1824 by Reverend William Buckland. Megalosaurus means ‘great lizard’ and it was about 9 metres long, and 3 metres tall.
The One With The Longest Name
The dinosaur with the longest name was Micropachycephalosaurus meaning “tiny thick-headed lizard”. Its fossils have been found in China, and it was named in 1978 by the Chinese paleontologist Dong.
