This was a movie made in the late 80s, early 90s. It was in color and in english. All I remember was it had dinosaurs in it, I think it took place in the modern world and two scenes stick out in my mind. The first was of a caveman antagonizing this woman before some kind of weird creature (animated by stop motion) bursts out of the bush and eats him. The other scene was of two smaller dinosaurs (animated by puppets) eating at a dinner table wearing bibs.
