__FORCETOC__
==Definition==
*''according to Hottinger (2006):''
'''TOOTHPLATE''' - (sipho; central pillar, pars auct.); a contorted plate running from an [[intercameral foramen]] to an [[aperture]], and attached to both. It may be shaped to form a single, double or spiral fold (or "[[tongue]]") with a free, often serrated distal end and distally protruding into the aperture. A toothplate separates partly or completely the main [[chamber lumen]] from an axial space ([[adapertural depression]]) in post-embryonic stages. It protrudes with a free edge distally and adaxially into the aperture. Interconnected toothplates in low-trochospiral umbilicate shells may produce a primary spiral canal. A toothplate is never associated with a foliar or stellar [[chamberlets]]. The use of the term in low-trochospiral rotaliid forms is under discussion (see Revets, 1993).
