Non avian dinosaurs appeared during the Carnian stage of the Triassic period about 220 million years ago. They diversified in the Jurassic and even more in the Cretaceous, but they died out 65.5 million years ago. All non avian dinosaurs lived during the Mesozoic era, but birds, which are a group of dinosaurs, continue to exist today.
Yes. Mosses were around long before the dinosaurs were.
No, apes did not evolve from dinosaurs. Apes belong to a different evolutionary line known as the hominids, which diverged from the lineage of dinosaurs millions of years ago. Dinosaurs became extinct around 65 million years ago, while apes evolved later, branching off from a shared ancestor with monkeys around 25 million years ago.
No, the Yellowstone supervolcano did not cause the extinction of the dinosaurs. The dinosaurs went extinct around 65 million years ago, while the most recent major eruption of the Yellowstone caldera occurred around 640,000 years ago. The extinction of the dinosaurs is most commonly attributed to a combination of factors, including a meteor impact.
