Item Chelid turtles from the Miocene freshwater limestones of Riversleigh Station, northwestern Queensland, Australia. American Museum novitates ; ; no. 2959.(New York, N.Y. : American Museum of Natural History, 1989) Gaffney, Eugene S.; Archer, Michael, 1945-; White, Arthur, paleontologist.Item New genus and species of extinct Miocene ringtail possums (Marsupialia, Pseudocheiridae) ; American Museum novitates, no. 3560(New York, NY : American Museum of Natural History, 2007) Roberts, Karen K.; Archer, Michael, 1945-; Hand, Suzanne.; Godthelp, Henk.The first unique genus of ringtail possums from the Riversleigh World Heritage Area in Australia is diagnosed and described. Gawinga aranaea is the type and only species of the new genus and is known from nine isolated lower molars. It has been recovered from three Riversleigh deposits: two are of early to mid-Miocene age, while the age of the other has yet to be determined. The new possum is larger than Oligo-Miocene species of Paljara, Pildra, and Marlu, but smaller than most extant taxa. It is characterised by a distinctive lower molar cusp morphology of parallel ridges extending primarily from the cristid obliqua, filling the occlusal basins. Additional autapomorphies include: extended, shelflike protostylid cristids and a bisected posthypocristid on m1, and posterior molars that have a metaconid ridge posterobuccal to the metaconid and an anteriorly positioned protoconid relative to the metaconid. It also possesses an enlarged protostylid on m1, a feature otherwise known only in extant genera. The precise phylogenetic position of Gawinga within the pseudocheirid radiation has yet to be determined, but it is tentatively identified here to be a highly derived pseudocheirid, apomorphic with respect to Paljara and Pildra species, and with no known descendants.Item Puntutjarpa Rockshelter and the Australian desert culture. Anthropological papers of the AMNH ; v. 54, pt. 1(New York : American Museum of Natural History, 1977) Gould, Richard A.; Archer, Michael, 1945-; Bronstein, Nancy.; Martin, Helene A.Item Systematic revision of the marsupial dasyurid genus Sminthopsis Thomas. Bulletin of the AMNH ; v. 168, article 2(New York : American Museum of Natural History, 1981) Archer, Michael, 1945-"The history of the systematics of Sminthopsis is reviewed. A terminology is defined for the skull, dentition, foot, and other external structures. Important dental characters include the size of the canines, premolar width, width and length of molars, anterior cingula, reduction of the paracone, development of the entoconid and orientation of metacristids and hypocristids. Two subgenera, Sminthopsis and Antechinomys, and the following species in each are recognized: S. murina (including albipes, fuliginosa, and tatei); S. ooldea, new rank; S. leucopus (including ferruginifrons, mitchelli, and leucogenys); S. virginiae (including nitela, rufigenis, lumholtzi, and rona); S. macroura (including froggatti, larpinta, stalkeri, and monticola); S. hirtipes; S. granulipes; S. psammophila; S. butleri; S. douglasi; S. longicaudata; S. crassicaudata (including centralis and ferruginea); subgenus Antechinomys: S. laniger (including spenceri). Other unique populations that may prove to be species are known from the George Gill Range, Northern Territory, and Doomadgee Mission, Queensland. Most species exhibit geographic variation and this is described as subspecies of each respective species. Some variation appears to be clinal within geographically widespread species, such as Sminthopsis murina. Size, tail length, tympanic wing development, brachycephaly, palatal fenestration, interorbital width, crowding of the premolar toothrow, and development of entoconids appear to vary as a function of relative aridity, both within and between species. This variation occurs independently in several different species groups. Sminthopsis granulipes and S. ooldea represent morphological extremes within the genus, the former possessing many structurally ancestral characters and the latter exhibiting the most derived characters--those adapted to arid environments. The species of Sminthopsis are most like those of Ningaui but also show similarity to species of Neophascogale and Phascolosorex"--P. 65.Item Vertebrate fossils and their context : contributions in honor of Richard H.
