Dinosaur

Dinosaurs roamed the Earth during the Triassic, Jurassic and Cretaceous eras between about 230 million and 65 million years ago.

Dinosaur bones were first found in Sussex in 1822 when Gideon Mantell found some teeth and bones in Sussex, England. He called it ‘Iguanodon’ (‘iguana tooth’).

The term "dinosaur" was coined in 1842 by the English paleontologist Richard Owen, and derives from Greek δεινός (deinos) "terrible, powerful, wondrous" + "lizard".

Scientists have no clue how dinosaurs mated, due to their enormous weight, plates, spikes and tails.

The low numbers of injuries in carnivorous dinosaurs indicate they may have been less aggressive with individuals of their own species than modern crocodilians.

The extinct reptile Nyasasaurus is described as the possible oldest known dinosaur from 243-million-year old fossils discovered in Tanzania.

Micropachycephalosaurus, a small herbivore from China, is the dinosaur with the longest name.
The shortest names are Mei and Kol, two feathered dinosaurs from China and Mongolia.

The first dinosaur to be given a name was megalosaurus (great lizard) in 1842.

The first evidence of dinosaurs was a tooth dug up by English obstetrician Gideon Mantell in 1822.

The Borogovia, discovered in 1982, was named for Lewis Carroll's borogoves in Jabberwocky. (“All mimsy were the borogoves”.)

The first dinosaur in space was a Maiasaura fossil taken on a space shuttle mission in 1985.

The smallest known dinosaur was the Fruitadens haagororum, which was only 4 inches (10 cm) tall and weighed less than two pounds, that's about the size of the smallest chihuahua.

The biggest known dinosaur is  Dreadnoughtus, which was 130 feet long and about 65 feet tall, and weighed 65 tons. It was discovered in 2005 in Argentina.

Scientists announced on April 29, 2015, the discovery of the first known dinosaur with membranous wings, Yi qi. The first and only known fossil specimen of Yi qi was found by a farmer, Wang Jianrong, in a quarry near Mutoudeng Village (Qinglong County, Hebei) in China ). Wang sold the fossil to the Shandong Tianyu Museum of Nature. The initial study of Yi was published in the journal Nature.

Velociraptors were feathered, weighed less than a human three-year-old, and looked like little, long-tailed chickens.

The four-ton Stegosaurus was equipped with an unusually small brain, comparable to that of a modern Golden Retriever.

Male stegosauruses had wide, ornamental back plates to impress females, while females had spiny, tall back plates to deter predators.

Tyrannosaurus Rex had eyes that were 13 times as precise as a human's eyesight, meaning it could see prey from almost four miles (six kilometers) away.

A Tyrannosaurus Rex would barely outrun a professional soccer player, reaching an all-out speed of 18 mph.

Dinosaurs didn’t roar; they mumbled or cooed.

The difference in time between when Tyrannosaurus Rex and Stegosaurus lived is greater than the difference in time between T-Rex and now.

Most dinosaurs walked on their toes.

Some dinosaurs had a possible lifespan of 300 years due to their slow metabolisms

The dinosaurs became extinct before the Rockies or the Alps were formed.

If 'Jurassic Park' were real, it would cost an estimated $11,907,000,000 a year to maintain.

The puppeteers who animated the raptors in Jurassic Park had to take a six-week-long class on how to move like a dinosaur.

The only dinosaurs in Jurassic Park that lived in the Jurassic era was brachiosaurus. All the others all from the later Cretaceous period.
