Abstract

Important new material attributed to the marsupial genus Paljara has been recovered from the early-middle Miocene deposits of the Riversleigh World Heritage Area in northwestern Queensland, Australia. Four species are now known from this genus, including P. hushae sp. nov. New material has facilitated a revision of the type species, P. tirarensae, originally described from the Leaf Locality in northern South Australia, and P. nancyhawardae, a relatively common species, unique to Riversleigh. P. nancyhawardae is mostly known from localities identified as early Miocene in age, potentially making it a valuable species for biocorrelation. Most significant is the identification and description of upper dentition for P. nancyhawardae, which was previously only known from lower dentition. In 1987, Paljara was described from a single species, P. tirarensae, and was identified as the most plesiomorphic pseudocheirid known. The new material has enabled a review of the phyletic position of the genus, which is no longer considered sister-group to all known ringtail possums.
