The Dinosaurs was in the earth approximately one hundred Sixty Millions years ago

So, there are many types of dinosaurs and phases in their lifetime

There are five phases in their lifetime the first its the Paleozoica

The Paleozoic era lasted about 300 million years and it most of the beings that live in the water moved to the land , becoming amphibians, while in turn the plants are adapted to oxygen from the atmosphere and various types proliferated insect

Phase Triasica: In this phase the reptiles begin to evolve further and are the first specimens of dinosaurs , especially highlighting two types

• Saurisquios: Saturnalia, Herrerasaurus, Staurikosaurus, Eoraptor y Alwalkeria.

• Ornitisquios: Pisanosaurus y posiblemente Lesothosaurus.

• The characteristics of these dinosaurs were quite

similar , with most a height of one or two meters and still most bipedal carnivores that inhabited the only continent that existed at that time on Earth : Pangea .

Phase Jurasica

• It is the most important phase in its history and in which dinosaurs were plentiful throughout the Earth , noting that in turn began to proliferate the first successor of the same species : birds and mammals.

• The period lasted from 199 million years to 145 million years after approximately and is where they have taken most dinosaurs we all know from the movies , museums and archaeological findings , perhaps by removing the most common knowledge that we will see in the next phase.

Phase Cretacea

• Last phase , ranging from 145 million back to 65 , is where the dinosaurs probably disappeared completely from Earth.

• This is the time of the family 's most famous dinosaur history : the Tyrannosaurus and its famous Tyrannosaurus Rex, which is considered by most as the most dangerous predator of all species .

Phase Cenozoica

• In this phase the scientific studies attest that there was absolutely no dinosaur and then change the planet suffered due to meteorite caused them to die and give way to mammals. It is for this reason that this phase is often called as the age of mammals .

What did the dinosaurs eat?

• For these many types of species, they were classified in:

• Omnivores: only eat plants and vegetables

• Oviparous: They fed on eggs

• Carnivorous: Only ear Meat
