Get ready for an ancient throwdown of epic proportions. It’s Tyranosaurus vs Triceratops. One is a meat-eating, mega-predator and the other is a vegetarian with three horns for three times the protection. Dino experts Riley Black and Kallie Moore will duke it out to see which animal is crowned the Smash Boom Best. After the debate, head to smashboom.org to tell us who you think won.

You can find Riley's books here and Kallie's books here! Kallie also hosts PBS' Eons.
