Will you be able to help organize the exhibition on dinosaurs?
Let's start. What do we know about dinosaurs? Dinosaurs were reptiles that lived in the Mesozoic era before humans appeared on Earth, and they were the largest animals that had ever lived. We know that they have existed because of the bones that we have found and the brands that have been on the rocks and earth .
They were oviparous , they had four legs and a tough and flaky skin like crocodiles. Dinosaurs roamed the Earth for over 150 million years , and then mysteriously disappeared . These reptiles could be from ferocious murderers until tender herbivores. The meaning of the word "dinosaur " is " terrible lizard " .
Many of them lived in groups and they were moving from one place to another , due to its strong legs. Dinosaurs had different characteristics that endowed them for survival. Carnivores have sharp teeth and claws adapted for hunting. Some herbivores reached enormous size. Others possessed natural weapons such as horns.
