  • Description

    Mammites Mammites nodosoides

    Shells of Mammites are typically stout, usually with a rectangular or squarish whorl section and flattish to slightly concave venter and can reach a diameter of 15–20 millimeters (0.59–0.79 in). Ornamentation is dominated by strong umbilical tubercles and moderate inner and outer ventrolateral tubercles. Ribs are somewhat prominent in juveniles stages but tend to become inconspicuous in the adult. The suture is ammonitic but rather simple. Some species, those with broad first lateral lobes in the suture, have been reassigned to Morrowites

    Mammites Mammites nodosoides

    Mammites and Morrowites are rather similar except that Mammites as redefined has a narrow first later lobe while that in Morrowites is broad and the early whorls in Morrowites are smooth except for widely spaced ribs and constrictions while those in Mammites have normal ribs and tubercles.
