[John Pojeta, Jr.; Bruce Runnegar; Geological Survey (U.S.),]. The group conforms to the definition of a phylum in that its members possess a highly characteristic structural plan but are exceptionally diverse in outward appearances and habitats.

The mollusks range in size from 60 ft and include such forms as snails, clams, slugs, oysters, mussels, octopuses, and tusk shells. The tusk shells or tooth shells, often referred to by the more-technical term scaphopods / ˈ s k æ f ə ˌ p ɒ d / (From Ancient Greek, σκᾰ́φης (skáphē) "boat", and πούς (poús) "foot"), are members of a class of shelled marine mollusc with worldwide distribution, and are the only class of exclusively infaunal marine molluscs.

Shells of species within this class range from Class: Scaphopoda, Bronn, North American Geology and Paleontology.

Moving beyond the borders of the classical core disciplines, Geobiology strives to identify cause-and-effect chains and synergisms between the geo- and the biospheres that have been driving evolution of life in modern and ancient environments.
