Dinosaurs were animals that appeared in the middle of the Triassic year, this name that was given to these animals means large lizard since they were related to large reptiles.
These animals seemed around 230 million years old and different races of them with different characteristics were known.
Dinosaurs differ in the type of hip:
-Saurischians, these are the ones with hips similar to lizards
-Ortinischia these are the ones with hips similar to those of birds
There is also a difference between them the type of food they eat, we find them:
-Carnivores, are those that eat meat, other animals and obtain their own food through hunting, small vertebrates, carrion, lizards, other herbivorous animals.
Among them are:
> Tyrannosaurus rex
> Verociraptor
> Allasaurus
> Compsognathus
-Gallimimus
> Albertosaurus
-Herbivores, are those whose diet consists of feeding on grass,
Among others are:
> Brachiosaurus
> Diplodocus
> Stegosaurus
> Patagotitan
> Apatosaurus
> Camarasurus

Carnivorous dinosaurs are characterized by:
-they move with the hind legs
-contains numerous very sharp, serrated and curved teeth
-inter-cranial joints, which allow movements of the skull bones that allow them to eat large animals
-long and hollow bones, which make it easier for you to move faster
-their spine is S-shaped in the neck, thus facilitating movement in the neck by raising it
-hands with claws, which makes it easier for them to grasp and hunt their prey, guaranteeing more the obtaining of their prey
Herbivorous dinosaurs,
-their teeth contain a beak jaw that does not allow them to chew, so the vegetables eat them with whole pieces
-contains long necks, to reach high places to get food
-contains a very large stomach and intestines
-they can eat up to 200kg of food
-swallow stones to aid digestion
