I made home made chocolate cake mix from a betty crocker recipe book, i doubled the recipe size so that i would have enought to make severl cakes, I made a 9′ 12 long cake and 2  9’23 round cakes  after my cakes cooled i used a bread knife to cut and shape my pieces, I had no idea what i was doing i just knew my grandson wanted a dinosaur cake so i drew a picture of what i thought it should look like and cut the cake pieces to match, i used thick iceing to hold my pieces together, and i made home made whipped frosting to frost the out side, with a recipe i found on the internet just heavy cream from your local grocery store and sugar, i use more than one color green on dinosaur body, for my teeth and claws i used splintered almonds, and for my spikes on the back i used square chocolet bars and just cut them to the sizes i needed, for my dirt i used ground gramcracker, i colored coconut with brown food coloring found at craft stores, and i use rock candies alson found at craft stores.
