__FORCETOC__<br />
==Definition==<br />
*''according to Hottinger (2006):''<br />
'''SUPPLEMENTAL SKELETON''' - the imperforate refolds and flying covers produced by outer lamellae that cover and/or restrict interlocular spaces to form enveloping canal systems, [[canaliculate spine]]s, [[marginal crest]]s and [[marginal cord]]s and the perforate chamberlets that are fed exclusively by canal orifices and that overgrow in more or less regular layers or tires the canalicular structures. The cavities of the supplemental skeleton can not be assigned to particular stages of growth because there is no direct connection with the orderly cameral system of shell cavities. In shells with an extensive supplementary skeleton, the cameral cavity system is reduced to neanic or even nepionic stages. <br />
<br />
<br />
''Remarks:'' Introduced by Carpenter (1862) long before lamellar theory was developed, and as now refined here, the term is a welcome complement to the terms [[exoskeleton]] and [[endoskeleton]]. Both of these terms subdivide the chamber lumen while "supplemental skeleton" structurizes extralocular, "outer" space. It is meant to be used as generic term regrouping all forms that have canaliferous enveloping, marginal and pseudospinose structures like ''Siderolites'', ''Pellatispira'', ''Calcarina'' and their allies along with all types of marginal cords (linked to a single sulcus) as in ''Sulcoperculina'' and their derivatives, ''Ranikothalia'' and all nummulitids s.str.<br />
