Atresius liratus Gabb, 1869  

( Fig. 8 View FIGURE 8. A – C, E, J D, I)

Material and occurrence. Many specimens from Rocky Creek (probably Valanginian, Early Cretaceous) including single moderately well preserved juvenile shell (GZG.INV. 84993).

Remarks. Atresius liratus   has been of uncertain taxonomic position so far (see Kiel et al. 2008 b for a review). The extraordinarily similar shell morphology of this species to the Recent bone eating abyssochrysoid Rubyspira osteovora Johnson et al. 2010   led to a suggestion that they may be related ( Johnson et al. 2010). Indeed, even the juvenile shells are somewhat similar, although the juvenile shell of A. liratus   is most reminiscent of the coeval Paskentana humerosa   (compare Fig. 8 View FIGURE 8. A – C, E, J D, I and 8 E, J herein). Therefore, we consider Atresius   to be a member of the newly established family Paskentanidae fam. nov. Clarifying the relation between Atresius   (and Paskentanidae) and Rubyspira   requires further research and collection effort.
