Cyathaspis is the type genus of the heterostracan order Cyathaspidiformes.[1] Fossils are found in late Silurian strata in the Cunningham Creek Formation, New Brunswick, Canada and Europe, especially in the Downton Castle Sandstone of Great Britain and Gotland, Sweden.[citation needed] The living animal would have looked superficially like a tadpole, albeit covered in bony plates composed of the tissue aspidine, which is unique to heterostracan armor.[citation needed]
Cyathaspis ludensis is the earliest British vertebrate fossil.[citation needed] It was found in rocks at Leintwardine in Herefordshire, a noted fossil locality.[citation needed]
