So I have some thoughts on feathered dinosaurs. The ones that come to the backyard feeder are considerably more temping to the cat. But the environments that they can live in are pretty much anywhere that you'd find a mammal.
Weirdly, these Dollar Store toys are about the right scale for D&D type miniatures (25-32mm):

They're also absolutely fabulous armatures for the money. I had to do a couple of unsavory things with a knife and a couple of wedges to get him to stand like a proper theropod, but otherwise that's just a texture layer. Y'know, the fun part. Well, besides plunking him down on the game table.
