Description
Apparatus seximembrate: Pa element scaphate, Pb angulate, M dolabrate or digyrate with one lateral process adenticulate, Sa alate with no posterior process, Sb digyrate, and Sc bipennate. [The originally designated type species was based on the Sa element of a seximembrate apparatus including elements of Spathognathodus cristulllS YOUNGQUIST & MILLER, 1949 (Pa), Ozarkodina curvata REXROAD, 1958b (Pb), Neoprioniodus camurus REXROAD, 1957 (M), Falcodus? alatoides. REXROAD & BURTON, 1961 (Sb), and Hindeodella sp. of REXROAD & FURNISH, 1964 (Sc); hence, H. cristulus (YOUNGQUIST & MILLER) has priority as the type species of multielement Hindeodtus.]
