Description
Genus based on tiny, subquadrate, posteriorly truncate, scaphate elements with bases broadly expanded laterally; may be smooth on upper surfaces or bear 1 or 2 long denticles on either or both sides. [Laterally adenticulate elements, which are numerous in known collections, have been referred by several authors to Anchignathodus SWEET, 1970 a junior subjective synonym of Hindeodus REXROAD & FURNISH, 1964. Such elements resemble laterally denticulate forms closely, are common in samples that lack any ramiform components of HilideodlfS, and are thus included here in Isarcicella.]
