8" rounds. Used cutoff cake scraps and a little bit of icing and kneaded it together (cake balls) to make a dough that I molded into the dino. Covered that with fondant. Using the "dough" worked GREAT and I totally recommend it. I don't like making RKT, so this is a compromise. I think it molds easier, too. Thanks to many CCers who uploaded other dino pics as inspiration!
