Interesting Facts About DINOSAURS

Dinosaurs were the dominant terrestrial vertebrates for over 160 million years, from the late Triassic period (about 230 million years ago) until the end of the Cretaceous (about 65 million years ago). here are some Interesting Facts on these Creatures :-

1. 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.

2. The longest dinosaur was Seismosaurus, which measured over 40 metres, as long as five double-decker buses

3. The heaviest dinosaur was Brachiosaurus at 80 tonnes. It was the equivalent to 17 African Elephants. Brachiosaurus was 16m tall and 26m long and is the largest dinosaur skeleton to be mounted in a museum.

4. The first dinosaurs evolved in the middle to late Triassic period, about 230 million years ago. It was only at the beginning of the Jurassic period, about 200 million years ago, that dinosaurs began their rise to dominance.

5. The Chicxulub impact crater created by asteroid is thought to be 65 million years old. It is also thought to be the source of the climate changes that led to the extinction of all of the dinosaurs.

6. We know about dinosaurs because fossils have been found. The fossils, which are generally found in sedimentary rocks, including fossilized body parts (bones, teeth, skin, claws, etc.), as well as trace fossils which show how the animals lived.

7. The smallest known dinosaur is Compsognathus, which lived in Europe during the late Jurassic, and was about the size of a chicken. Compsognathus is believed to have eaten insects, lizards and other small animals.

8. The word "dinosaur" was coined by Sir Richard Owen, who also founded the Natural History Museum in London, England. "Dinosaur" means terrible lizard, and is based on the Greek words "deinos" (terrible) and "sauros" (lizard).

9. Although birds seem to have evolved from dinosaurs, no non-avian flying dinosaurs are known. However, at the time of dinosaurs there were many flying reptiles, known as pterosaurs.

10. The only dinosaurs we can know about are the ones that leave fossil remains, but fossilization is an extremely rare process. So, there is chance that there are species that are not still Classified.
