Stun claws are weapons worn by iguanodon on their thumb spikes. They can release electricity, stunning attackers or distracting them. Iggy Tooth, a crewmember on the Sauropod, uses them in the Astrosaurs series to battle foes like mammoths and raptors. The other iguanodon who help him in the engine room, as is seen in Riddle of the Raptors, use stun claws in combat as well.
