The phylogenetic relationships of the Scaphopoda, one of the ‘lesser’ molluscan classes, with the other conchiferan taxa are far from clear. They appear either as the sister‐group to the Bivalvia (Diasoma concept) or to a Gastropoda–Cephalopoda clade or to the Cephalopoda alone (helcionellid concept).

Cretaceous Scaphopoda (Mollusca) of Australia and their palaeobiogeographic significance
Alcheringa, 1999The Cretaceous scaphopod (molluscan) fauna of mainland Australia is characterised by a rather depauperate and poorly known assemblage of five species: dentaliids Dentalium (Dentalium) n. sp. A (probably Aptian), Dentalium (Dentalium) n. sp. B (Cenomanian), and Dentalium (Dentalium) n. sp.

The Scaphopoda are marine infaunal carnivores that feed on foraminiferans and other microorganisms selected and manipulated by their unique feeding tentacles or captacula. Their tusk-like shell is open at both ends; the burrowing foot and captacula protrude anteriorly, while respiratory currents pass through the posterior opening.

Scaphopod mollusks (Scaphopoda)
2009Abstract The tusk shells (500 sp.) are grouped into 14 families and two orders within the molluscan Class Scaphopoda. Only two molecular studies have focused on phylogenetic relationships within scaphopods. Estimates of divergence times among families are estimated here.

Mollusca: Caudofoveata, Monoplacophora, Polyplacophora, Scaphopoda, And Solenogastres [PDF]
, 2015 AbstractMolluscs are the second most speciose metazoan phylum, and arguably molluscs demonstrate the largest morphological disparity. The dramatic body-plan modifications and changes among the molluscan clades leave few consistent characters that can be directly compared across all eight living classes.
