Realm of Rubber Dinosaurs

Since (b)'s teeth aren't undercut, Marx didn't need another mold segment just for the mouth. Tyrannosaurus (b) was made in a three-segment mold - right, left, and front (ventral/front surface, and the inboard surfaces of the legs and arms). Instead of crosshatched skin like Tyrannosaurus (a), (b) has more carefully delineated scales on his legs, and a curious bricklike tiled pattern on his body.
