Abstract

An evolutionary scenario suggests that branchiosaurids originated by invention of a key innovation: specialized pharyngeal denticles, housed in gill clefts, served as a filter-feeding device focussing on plankton. The group diversified in part, by patterns of delayed development of the upper jaw and cheek resulting in a kinetic maxilla, thereby permitting manipulation of the oral margin during suction feeding. It can be shown that within the Apateon-clade, the second component evolved along different lines into rather different adaptational directions, producing a range of morphotypes controlled by minor heterochronic changes.
