505 mya - mid-Cambrian | everywhere
Hurdia was one of the largest organisms in the Cambrian oceans, reaching approximately 50 cm (1.5 feet) in length. Its head bore a pair of spiny claws which shoveled food into its pineapple-ring-like mouth.
A hollow, spike-shaped shell protruded from the front of its head.
