Pigasauruses are species of pig-like creatures which existed during the Stone Age featured in the franchise of The Flintstones.
Pigasauruses were much like pigs but had a single horn on the top of their heads and spikes on their backs. Notice the extra large capacity of the hog's stomach and the amazing speed of its' digestion. Meal after meal, day after day, this garbage disposal made a clean up a snap.
Obviously, the pigasaurus was a creature perfectly suited to its job as a garbage disposal under the kitchen sink which it could consume astounding amounts of trash, including bones and food that other people ate.
