1		-The apparatus composition was proposed by DZIK (1976) but the species remains only superficially known. Except that the apparatus is composed of an oistodontiform element with long cusp and that elements of the symmetry transistion series with two sharp ridges at their sides
2		-have characteristically internally expanding bases, little can be said about it. The morphology of elements of the species is closely similar to that of// Besselodus arcticus// ALDRIDGE, 1982 and it is a matter of dispute whether this is an effect of a secondary development of geniculation of the ne elements in the //Dapsilodus// lineage or a development of peculiar oblique striation in elements of them symmetry transition series of// Paltodus//, making them identical with respective elements of //Dapsilodus//.
