Rumblin’ Tumblin’ Gastroliths Kit


Three tupperwares will replicate three different digestion systems: one with no stones (humans, meant to be chewed), one with small stones (like a chicken gizzard), and one with large round stones (like plesiosaur gastroliths). This proves the usefulness of gastroliths for digestion in animals that can’t chew, while comparing it to humans and birds.
