Abstract
A 12 mm long conical tooth crown is described from the Middle Bathonian (subcontractus Zone) deposits of the �Gnaszyn� clay-pit at Gnaszyn Dolny, Poland. The fossil represents the first reported actinopterigian (basal Neopterygii) material from the Middle Jurassic of Poland. The specimen bears a distinctive ornamentation of anatomising ridges and an acrodin cap at the apex indicating a large actinopterygian fish. The tooth morphology and size is typical of a large macrophagous predator.
