Dinosaurs lived in the Mesozoic Era. They first appeared at least as far back as 230 Million years ago. Many of them were some of the largest creatures to ever inhabit Planet Earth. Really big dinosaurs evolved more than 100 Million years ago. The Cretacious-Tertary extinction event, which took place 65 million years ago, wiped out most of the dinosaur species, leaving only Birds to survive. . . After that, Mammals evolved to become the dominant land animals. Some people believe non-avians dinosaurs may still exist. Wether or not that's true is up for debate.
Few people would dispute the fact that they have seen a bird at at least one point in their lives, and there are plenty of paintings of them too . Some people believe birds are dinosaurs.
Humans evolved during the last 3 million to 9 million years. Humans and large dinosaurs did not live at the same time.
