Dinos are an amazing and unique form of life, which are mostly composed of water and protein. These little creatures have walked the earth for millions of years and have left a lot of fossil fuels. It is estimated that there are more than 60 different species of dinos. However, only a few of them have been discovered so far. And even those that have been discovered are not all of the same species. There are two main groups of dinos: the theropods and the sauropods.

The first group contains the smallest creatures. The smallest species in this group are the microminut dinos. They are very small, and some of them are very light. However, they are the most abundant, and they are very well adapted to the environment in which they live. They have no external skeleton, and their entire body is composed of light-weight muscle and tissue. The second group contains the biggest creatures. These are the giants of the dino world, and they are divided into two sub-groups: the theropods and the sauropods. The first group is smaller and more lightweight, and the second group is larger and more heavy.
