cf. Pulvinites sp. (Fig. 5 A, B) Material. Five specimens from Moonlight North (Y16/f0694), large shell fragments, two numbered, L4650 (Fig. 5 A), L4651 (Fig. 5 B), UOA. Description. Shell large (up to ca. 70 mm at widest diameter), composed of very thin plates, outline irregular; dimpled texture observed on many of the plates, some plates more or less smooth without dimpled texture, some with calcitic lamellae. Remarks. Specimens are numerous at only one site, found in dense and diverse assemblages with caryophylliid corals, mytilids and thyasirids. It cannot be confirmed that the specimens belong to Pulvinites Blainville, 1824, with such internal features common to all species of this genus [e.g. posterior adductor muscle scar, anterior pedobyssal retractor muscle scar, byssal foramen, posterior pedal retractor muscle scar and suture (Palmer 1984; Tëmkin 2006)] not evident on any of the specimens, nor do any have the distinctive ligamental area preserved. However, the general morphology of the shelly plates closely resembles the nature of those of P. exempla (Fig. 5 C: cf. Marshall 1998; Tëmkin 2006).
