Dinosaur cake - Maybe could use green sugar sprinkled on chocolate frosting for a similar effect. The rock candies and cookie crumbles add nice detail. Kind of like this Branche except without the dino fossil portion, just dinos.
This Dinosaur Bones craft is easy to make with our printable T-Rex dinosaur skeleton! The kids can pretend that they are on an archeological dig, a great craft for preschoolers on up!
