THE pre Holocene-Late Pleistocene record of Phascolarctos in Australia is extremely meagre. There are at least two, possibly three extinct species of Phascolarctos in addition to the extant Phascolarctos cinereus (Black 1999). P. yorkensis (syn. Cundokoala yorkensis; Black and Archer 1997) is known from the Early Pliocene Curramulka Local Fauna, South Australia (SA), and the Late Pleistocene Wellington Caves Local Fauna, New South Wales (Archer et al. 1997; Pledge 1992). P. stirtoni occurs in the Late Pleistocene Cement Mills Local Fauna, Queensland, and is known only from a partial maxilla containing P3-M2 (Bartholomai 1968, 1977). Phascolarctos material from the mid- Pleistocene Victoria Fossil Cave and Spring Cave, Naracoorte, SA, have also been referred to P. cf. stirtoni but remain undescribed (Reed and Bourne 2000; Moriarty et al. 2000). P. maris is known from a single lower molar from the Early Pliocene Sunlands Local Fauna, SA (Pledge 1987). Black (1999) cast doubt on its validity, suggesting its features may fall within the intraspecific variation of P. stirtoni. If P. maris is referable to P. stirtoni it is another South Australian instance of this species, and extends its range back to the Early Pliocene. The new phascolarctid material documented here is from the early Pleistocene Nelson Bay Local Fauna, Portland, Victoria (141o 35? E; 38o 36? S). It is therefore an important additional southern occurrence of a species larger than the living P. cinereus, and is the only pre- Late Pleistocene record of the Phascolarctidae in Victoria.

Cougars ( Puma concolor ) are one of only two large cats in North America to have survived the Late Pleistocene extinction (LPE), yet the specific key(s) to their relative success remains unknown. Here, we compare the dental microwear textures of Pleistocene cougars with sympatric felids from the La Brea Tar Pits in southern California that went extinct at the LPE ( Panthera atrox and Smilodon fatalis ), to clarify potential dietary factors that led to the cougar's persistence through the LPE. We further assess whether the physical properties of food consumed have changed over time when compared with modern cougars in southern California. Using dental microwear texture analysis (DMTA), which quantifies surface features in three dimensions, we find that modern and Pleistocene cougars are not significantly different from modern African lions in any DMTA attributes, suggesting moderate durophagy (i.e. bone processing). Pleistocene cougars from La Brea have significantly greater complexity and textural fill volume than Panthera atrox (inferred to have primarily consumed flesh from fresh kills) and significantly greater variance in complexity values than S. fatalis . Ultimately, these results suggest that cougars already used or adopted a more generalized dietary strategy during the Pleistocene that may have been key to their subsequent success.

ABSTRACT Only a few vertebrate faunas are known for the Southern High Plains from the late Pleistocene and early Holocene. This review focuses on vertebrate local faunas from two major localities on opposite sides of the region but in the same drainage system that provide proxy data for paleoenvironmental reconstructions from ca. 11,600 to 8600 yr BP. Both localities are archaeological sites within deeply stratified, radiocarbon-dated deposits. Four distinct, successive vertebrate local faunas are known for Lubbock Lake covering the period 11,100 to 8600 yr BP. Two distinct, successive vertebrate local faunas come from Blackwater Draw Locality # 1 for the period 11,600 to 10,500 yr BP. All of the local faunas are disharmonious but the extent of disharmony and diversity varies. Faunal elements from the Northern Plains and Southeast are the most notable. The late Pleistocene local faunas indicate mild winters which did not maintain freezing conditions and cool summers with a more effective moisture regime, reduced annual temperature fluctuation, and less seasonality. The beginnings of a warming trend, greater seasonality, and increased annual temperature fluctuation denote the early Holocene. The latest local fauna marks the last of the pluvial-related ones and heralds the end of pluvial conditions beginning around 8500 yr BP. The successive local faunas illustrate the complexity of disharmony occurring in unglaciated regimes during déglaciation of North America.
