Beyond the game

The real Tokummia

Tokummia was an early mandibulate arthropod with a carapace and substantial feeding appendages. Its fossils are important for the history of jaws in the arthropod branch.

Its head and feeding appendages provide evidence about the early history of mandibulate arthropods. The carapace and segmented body record a form different from a modern crab.
