Cretaceous Period


145-66 million years BC

- It is the geological period in which the disappearance of dinosaurs and many other species of fauna and flora occurred. In the Cretaceous period, the Earth divided again to form the continents we know today, albeit in different positions.

In this way, dinosaurs evolved independently in different parts of the world, becoming more diverse.

It was in the mid-Cretaceous that approximately 50% of the world's known oil reserves today were formed. Of these, the main ones are located in the vicinity of the Persian Gulf and in the region between the Gulf of Mexico and the coast of Venezuela.

Some of the best-known dinosaurs of this period are Protoceratops, Triceratops, Pachycephalosaurus, Baryonyx, Tyrannosaurus or Velociraptor.

The evolution of dinosaurs ends in this geological period. At the end of the Cretaceous period, most of the fauna, both terrestrial and marine, including all species of dinosaurs, suffered massive disappearance.
