Triceratops Birthday Cake

My son had a dinosaur birthday and wanted a triceratops cake, so this is what I came up with. Buttermilk Devils food cake with decorator's buttercream icing. Body and legs are cake, tail is rice krispie. Head armor, horns, beak and eyes are fondant . Toe nails are marcona almonds, and the rocks are chocolate rock candies my husband got in Alaska and really wanted me to use. The cavemen were a last minute addition and are my sons toys. I taped a wood skewer to one as if it were a spear. The cake is carved.
