- This repeated succession of cyclothems of differing character indicates a rhythm of larger order than that shown in the individual cycles and suggests the desirability of a term to designate a combination of related cyclothems. The word "megacyclothem" will be used in this sense to define a cycle of cyclothems.

- The Kansas sequence, with its complex succession of marine limestones, was interpreted as recording several transgressive-regressive cycles, each of which was likened to a cyclothem. Because it was believed to correspond to several, perhaps as many as five, incomplete cyclothems, it was named a megacyclothem (Moore, 1936, p. 29).
