Introduction
The Dentaliida are characterised by a conical foot, a radular configuration in which the rachidian (central) tooth is wider than high, and shells which most commonly are ribbed, always widest anteriorly and frequently have a single slit or notch and/or shell pipe developed apically. Features of the mantle, midgut gland, foot musculature and mantle epithelium further differentiate the Dentaliida from Gadilida (Steiner 1992; Shimek & Steiner 1997; Steiner & Palmer 1998). The shell may vary from strongly curved to almost straight and from robust and opaque to fragile and almost transparent.
The order is represented in Australia by six families: the Dentaliidae, Calliodentaliidae, Fustiariidae, Gadilinidae, Laevidentaliidae, and Omniglyptidae. Dentaliida are sometimes taken alive in large numbers in grab samples or dredgings, indicating that at certain localities they form a significant component of the benthos (Lamprell & Healy 1998).
Fewer than 20 Australian fossil species are recorded (Tate 1887, 1899; Pilsbry & Sharp 1897–1898; Ludbrook 1956, 1959, 1984), including 15 from the Tertiary and four from the Carboniferous (Yoo 1988).
