What does “Dinosaurs” bring to mind?

Continuing on to the third core concept of the “World of Vikings & Mayans & Dinosaurs” brings us to “Dinosaurs.”

So what pops into my mind when I think “Dinosaurs?”

1) Landscapes full of strange vegetation. Giant ferns. Jungle-like underbrush. Teeming with small creatures like insects, lizards, and proto-mammals. Rivers full of giant crocodiles. Seas full of monsters.

2) Carnivores stalking their enormous prey. Giant carnivores like T-Rex, Allosaurus, as well as packs of smaller hunters like Velociraptor and Deinonychus. Huge sauropods like Brachiosaurus and Apatosaurus (which was called Brontosaurus when I was a kid). Various armored herbivores like Stegosaurus, Triceratops, and Ankylosaurus.

3) “Cavemen.” Lizardmen. The Sleestak from “Land of the Lost.” Strange, possibly alien cultures.

4) Extinction. Cataclysm. Volcanoes. Earthquakes. Fires. The fall of one order, paving the way for another to rise.

That’s what I’ve got with a few minutes thought.
