Seximembrate apparatus structure of the Late Cambrian coniform conodont Teridontus nakamurai from the Chatsworth Limestone, Georgina Basin, Queensland

The multielement structure of the Late Cambrian euconodont Teridontus nakamurai (Nogami, 1967) is shown to be a seximembrate apparatus consisting of Sa, Sc, Sb, Sd, Pb and Pa elements. No M element has been identified and none is expected in this type of conodont. All elements are coniform with a hyaline base and albid tissue in the cusp extending from the apex of the basal cavity to near the cusp tip. The cusp tip is usually hyaline. The albid tissue is dense and the juncture of hyaline and albid tissues at the basal cavity apex is usually abrupt and planar, rather than tapered as found in most coniform element species. Albid tissue fills the entire diameter of the cusp, and there is no outer layer of hyaline tissue. The S elements have a relatively long base and are differentiated by their cross-sectional shape. The P elements have a short base and different cross-sectional shapes. The surface of all elements is covered with a very fine striate ornament, but the elements lack other surface structures, such as keels, carinae, costae and grooves.
