Aunque parezca increíble, los dinosaurios caminaron por la Tierra durante 150 millones de años, mientras que los seres humanos solo llevamos aquí tres o cuatro millones de años. Descubre los primeros dinosaurios que vivieron durante el periodo Triásico, como el Herrerasaurus o el Eoraptor, además de los inmensos herbívoros de cuello largo del Jurásico, como el Diplodocus, y los grandes depredadores del Cretácico, como el Tyrannosaurus rex. Though it's hard to conceive, dinosaurs walked the Earth 150 million years ago. As humans, we've only been around for 3 or 4 million years. Learn about the Herrerasaurus and the Eoraptor, some of the earliest dinosaurs that lived during the Triassic period. You'll also learn about the massive long-necked herbivores that lived during the Jurassic period, and the feared Tyrannosaurus Rex of the Cretaceous period.
