Family Mochtyellidae Kielan-Jaworowska, 1961 Genus Mochtyella Kielan-Jaworowska, 1961
Type species: Mochtyella cristata Kielan-Jaworowska, 1961 , erratic boulder, Poland; Ordovician .
Remarks.—Isolated jaws of similar shape to MI of the genus Mochtyella were, in older literature, often assigned to Staurocephallites Hinde, 1879. However, in the type species of the genus— S. niagarensis Hinde, 1879 only one ridge of denticles is visible, while both MI of Mochtyella have two or three denticulated ridges. The difference is of generic rank (see Kielan Jaworowska 1961, 1966).
