Almost all of us have watched the movie “Jurassic Park”, but how much do we really know about the creatures called “dinosaurs” ? Did we know that the period they occurred in was called Triassic period? or What does even “Jurassic” stands for?
We have played with little dinosaurs models throughout our childhood and have been inquisitive ever since. Here are some facts about these magnificent animals that’ll break all the mysteries.
1. First Ever
Please don’t go by the heading because it’s not what it looks like and in fact is just the opposite. Dinosaurs were actually not the first to exist. Archosaurs (giant lizard) and pelycosaurs came 20 million years before the Dino.

2. Most Successful
This might or might not diminish your interest in history. The fact is that the dinosaurs have been the most successful reptile to rule the earth. Human beings have been here for few thousands of years but that is just few seconds in the dinosaurs time.
We know that there are two kinds of dinos: Herbivores and Carnivores, but the paleontologists have a different saying in this. They divide the creature into saurischian (lizard hipped) and ornithischian (bird-hipped).
4. ..And they Became Birds!
What!!!! No, seriously, there have been proofs that the birds have evolved from small and feathered theropods during the late Jurassic period.

5. Endothermic or Exothermic?
The modern reptiles are cold blooded or exothermic, which means that they have to rely on outer temperatures to maintain the body heat. But did you know that carnivores dinosaurs were endothermic or warm blooded. Mustn’t be warm when they hunt though.
6. Majority Were Herbivores
Though the giant dinosaurs like Tyrannosaurs gets to be in the lime light all the time but it is true that the majority of dinosaurs were not carnivores but herbivores!
7. Not Everything With “saurs” Was Dinosaurs
Other kinds like the flying pterosaurs and swimming plesiosaurs, ichthyosaurs and mosasaurs weren’t dinosaurs at all; and some of them weren’t even all that closely related to dinosaurs!
We all just know about a few kinds of dinosaurs (mostly, Tyrannosaurs Rex!), but did you know there are almost 2,468 species accounted in the Mesozoic Era.
