Abstract
New Protopteraspis material from Shropshire is sufficiently similar to Protopteraspis leathensis from the Welsh Borderland, and the type‐species Protopteraspis gosseleti from France, to justify transfering P. leathensis to P. gosseleti. The Anglo‐Welsh, biostratigraphic leathensis Zone is changed to the Protopteraspis Zone (sensu Blieck and Janvier 1989). Possible lifestyles are discussed for Protopteraspis gosseleti.
