At least two families of scaphopoda, the Dentaliidae and the Siphodentaliidae, are present in the Gault. The former is represented chiefly by the ubiquitous Dentalium (Fissidentalium) decussatum (J. Sowerby), resembling an elephant's tusk in miniature; Cadulus (Gadila) gaultinus Gardner belongs to the latter family. Examples of both families are shown below.
