It is studied by the systematic composition of Bivalve mollusks from family Trigoniidae Lamarck, 1819, genus Myophorella Bayle, 1878, from Oxfordian deposits of the north-western outskirts of Donbass. Based on geographic distribution and stratigraphic position of the members of certain genus and sculptures of the external surface of the shell of the bivalves that are the members of certain genus of the family, the conclusions were drawn about the origin Myophorella in general and species of Myophorella genus, collected from the Oxfordian deposits from the south-eastern of Ukraine.
