... Terminology Molar position homology follows Luckett (1993). Molar cusp nomenclature follows Rich et al. (1978), with the exception of the structure reported therein as the hypocone, which is referred to as the metaconule following Tedford & Woodburne (1987). Premolar cusp nomenclature follows Pledge (2003). ...

... The Vasquez Formation unconformably underlies the Tick Canyon Formation in the Mint Canyon area of Los Angeles County, southern California (Jahns, 1940). K-Ar determinations for andesitic and basaltic lava flows at the base of the Vasquez Formation are 25.6 ± 2.2, 24.5 ± 0.8, and 20.8 ± 0.8 Ma (Woodburne, 1975;Woodburne et al., 1982; recalculated from 24.9 ± 2.1, 23.9 ± 0.8, 20.2 ± 0.8 Ma; last determination regarded as too young byWoodburne, 1975). The Tick Canyon Formation yielded the early late Arikareean Tick Canyon LF (Jahns, 1940). ...

... On the basis of stage-of-evolution comparisons of several described but unnamed taxa, including an undescribed genus and species of ilariid (Murray & Megirian, 2006), the Pwerte Marnte Marnte LF was considered to pre-date the basal local faunas of the Etadunna and Namba formations of the southern Lake Eyre Basin (Murray & Megirian, 2006;Megirian et al., 2010). The recovery of an ektopodontid taxon from the assemblage is useful in this regard because this group has often been viewed as one of the most biochronologically informative for the Australian Oligocene through Miocene (Woodburne et al., 1985;Pledge, 1986;Woodburne & Clemens, 1986a;Pledge et al., 1999;Megirian et al., 2004). Within Chunia, Woodburne and Clemens (1986a) considered the poorly represented Chunia sp. ...
