«Node 6 separates L. pyx (Gardner, 1936), from members of the tropical Atlantic stem group. This aberrant species was originally described from the Shoal River Formation of Florida, now regarded as late Middle Miocene in age (Jones et al., 1993). It is characterized by a high, trigonal shape, pointed auricles, and unusually well-differentiated key and normal ribs, the latter being very fine relative to the key ribs. Although J. T. Smith (1991a, p. 7) assigned this species to Stralopecten Tucker-Rowland, 1938, studies in progress show that Stralopecten has a later origin and has morphological features that are not shared by Gardner’s species. Aside from its shape, L. pyx resembles other primitive Lyropecten in ribbing pattern.»

«Lyropecten pyx Gardner, here referred to "Stralopecten," has the growth form and triangular auricles of Stralopecten but hinge teeth similar to those in the "Lyropectens" listed here. Tucker-Rowland (1938b) noted that hinge teeth are present in juveniles but obsolete in adults of the type species of Stralopecten, S. ernestsmithi. All of these taxa need further work.»
