Tontoia is a dubious genus of arthropod known from the Cambrian Burgess Shale, known from a fossil proposed to be the external mould of an arthropod exoskeleton. In its original description by Charles D. Walcott it was initially suggested that Tontoia might be a trilobite,[1] but it is currently considered to be a nomen dubium, and it is unclear whether it even represents an arthropod.[2][3]
