Harrytoombsia is an extinct genus of arthrodire placoderm from the Early Frasnian stage of the Late Devonian period. Fossils are found from Kimberley, Australia.[2] It was a fast-swimming predator, and it had sharp blades of enamel-like material around the outer edge of the jaw for catching prey.[3]
