Protemnodon large sp. indet.

Referred material. NMV P215990, right I1; NMV P173663, right I1 and I3; NMV P173637, right I2; NMV P218260, left I2; NMV P173688, left and right I3, and left I2; NMV P215992d, right I3; NMV P215993, right I3; NMV P216030, left I3; NMV P216033, right I3; NMV P216034, left I3; NMV P218249, right posterior portion I3. NMV P173675, partial left innominate; NMV P215909; right ulna; NMV P216071, left distal tibia epiphysis and part shaft; NMV P216154, partial right distal tibia epiphysis; NMV P216158, proximal end right fibula shaft +; NMV P200562, proximal end right fourth metatarsal; NMV P216141, distal end left fourth metatarsal; NMV P216152, left fourth metatarsal; NMV P216148, left fifth metatarsal; NMV P216151, left fifth metatarsal; NMV P216118, partial right calcaneum*; NMV P216155, right astragalus +; NMV P216139, right cuboid +; NMV P216160, partial right cuboid*; NMV P200541, distal phalanx; NMV P216171, distal phalanx; NMV P216200, distal phalanx; NMV 173669, ungual; NMV P216169, ungual, NMV P216195, ungual. *These elements were found in the same location and display a similar state of preservation, therefore are probably from the same individual. + These elements show very similar preservation, and although there is no location data, they were collected by the same person and are probably from the same individual.

Remarks. A number of isolated Protemnodon upper incisors are present in the Nelson Bay LF ( figs. 5I–K ) as well as several postcranial elements ( fig. 7 ); however, owing to the scarcity of Protemnodon incisors in the fossil record, their lack of association with other dental material identifiable to species, the scarcity of associated postcranial and dental material, confusion over the validity of P. roechus and apparent intraspecific morphological variability, it is not possible to confidently assign any of the Nelson Bay specimens to species. It is probable that both P. roechus and P. brehus are represented among them.
