Eleven trigoniid species of the genera Trigonia Bruguiere, Myophorella Bayle and Rutitrigonia van Hoepen, including one new species, R. skorkovensis sp.n., are described from the Jurassic of Poland. The representatives of the genus Rutitrigonia are reported for the first time fro'm the Lower Kimmeridgian of Poland which markedly increases the stratigraphic and geographic range of that genus hitherto considered as limited to the Upper Kimmeridgian - Upper Cretaceous of the Phillippines, Japan and the southern hemisphere.
