Dinosaur: Book Review :: What Is A Dinosaur?
The term “dinosaur” means “terrible lizard,” but the truth is that not all dinosaurs were gigantic, ferocious, bloodthirsty creatures. While many were large, some were actually quite small; while many were meat-eaters, some survived solely on vegetation. Here are some other facts about dinosaurs that may challenge the image you have in your mind.
BrainsNever judge a dinosaur's intelligence by his size. Dinosaurs like the Troodon had the largest-sized brain in relation to their body weight, while some giant herbivores, despite their enormous size, had brains no bigger than the size of a plum.
Feet & Legs
The big carnivores and the raptors had sharp talons on their feet for slashing and ripping at flesh, while the giant herbivores had feet similar to an elephant’s. And, despite their enormous size, they were able to walk along as quietly as elephants do today.
All dinosaurs' legs extended directly beneath their bodies, instead of sprawling out to either side like modern-day reptiles’ legs. This design allows some dinos to become truly massive, with pillar-like legs supporting their weight. It also gave other dinosaurs great speed and agility.
Most dinosaurs could walk and run on their two back legs, using their tail for balance.
Dinosaurs, like reptiles today, laid eggs, and it seems like they were pretty good parents, too. Nests have been found with eggshells crushed into bits, as if the baby dinosaurs had stayed there for some time, being fed and looked after.
