MAISEY, J. G. 1976. The Jurassic selachian fish Protospinax Woodward. Palaeontology, 19, 4, 733–747.
J. G. Maisey Protospinax Woodward, 1919 (Kimmeridgian) is synonymous with Belemnobatis Thiolliere, 1854, and is a rhinobatoid. The paratype of P. annectans Woodward, 1919 differs fundamentally from the holotype; it is described as Squalogaleus woodwardi gen. and sp. nov. and has galeoid-like jaws which lack an otic process. Primitive rhinobatoids and squatinoids have similar pectoral fin structure and a pectoral notch, suggesting a close primitive relationship. The Palaeontological Association (Free Access)
