This has to be one of the oddest choices for a cover for a book in the West of Eden series. This is the Czech edition of Return to Eden published by Straky Na Vrbe (if I’m reading that correctly) in 2000.
I don’t know what the covers for the other volumes in the series looked like, but… the trilogy isn’t really about cute dinosaurs is it? Or maybe I missed the point of the whole series. 🙂
