Dinosaurs are a diverse group of animals of the period Dinosauria. They first appeared during the Triassic period, and became the dominant terrestrial vertebrates for 135 million years, from the beginning until the end of the Cretaceous (65.5 million year ago)
I am Giganotosaurio
I am going to vomit.Your mouth smells very bad.
The word dinosaur means "terrible lizard" the name is a mistake because dinosaurs weren’t lizards.They were a separate group of reptiles with a distinct upright posture not found in lizards.
Scientist think that dinosaurs were similar to birds. For example in their breathing system.
Some dinosaurs were carnivores (meat-eaters) but most were herbivores (plant-eaters). A large number of plants (called producer) can support a smaller number of plant-eaters (called primary consumers). These plant-eaters are eaten by a smaller number of carnivores (secondary consumers).
Carnivores ate lizards, turtles, eggs, or early mammals. Some hunted other dinosaurs or scavenged dead animals. Herbivores ate plants (but not grass, which hadn't evolved yet).
Dinosaurs hatched from eggs laid by females after sexual reproduction.Internally, these eggs were similar to eggs of reptiles, birds and primitive mammals.
Some dinosaurs cared for their eggs, others simply laid them and then abandoned them.
I HAVE A DREAMThat one day my descendants will live in harmony with those small dinosaurs

several theories about our
extincion, like we comit
suicide. But a recent theory
say that a meteorite impact on
Earth about 65 millions of years
ago and our lifes finished like
this power point.
