Reddit mentions of Dinosaur Fantastic (Daw Book Collectors)

I keep trying to sell people on Broncosaurus Rex using exactly those words. So far, no takers. :(

Have you read Dinosaur Fantastic?

I wonder if it could be a short story in a collection. Doesn't seem terribly likely if you think it was YA. Something like Dinosaurs, Dinosaurs II, Dinosaur Fantastic, Return of the Dinosaurs.
