The bone-headed Pachycephalosaurus. These two-legged dinosaurs have a dome of bone on their head surrounded by a number of lumps and bumps. This figure from the Favorite Collection is posed mid-stridee witth its tail held out straight, and their is an appealing zig-zag pattern running along the back: certainly one of the best models of this genus.
