==Definition==
*''according to Hottinger (2006):''
'''CHOMA''' - (pl. chomata; German: Basalreifen); a dense deposit on previous whorl constituting the chamber floor, and in fusulinids forming a pair of parallel ridges, each extending from a tunnel margin to the previous one. May extend progressively polewards over the entire chamber floor in staffellids, much like a basal layer in fusiform porcelaneous shells.
