The Plio-Pleistocene Sminthopsis floravillensis consistently fell within Sminthopsini as in [ 36 ], although it is unclear whether this fossil taxon is a member of any particular sminthopsin subclade. For our outgroup terminals, we used representatives of the following modern marsupial orders: Peramelemorphia the extant Echymipera kalubu and Perameles nasutaand the fossil Yarala burchfieldiwhich is a close relative of Dasyuromorphia within the superorder Agreodontia [ 80 ]; Microbiotheria the extant Dromiciops gliroideswhich Node dating phylogeny the closest modern relative of Australian marsupials [ 87 ]; and Didelphimorphia the extant Caluromys philanderDidelphis virginianaand Marmosa murinawhich are relatively plesiomorphic non-australidelphian marsupials [ 88 ].

Flannery TF. PartitionFinder: combined selection of partitioning schemes and substitution models for phylogenetic analyses. Table 3. Given that our dated analyses suggest that earliest divergences among species currently classified as Sminthopsis are similar in age to those within Phascogalini and Dasyurini both of which are classified into multiple genera , the second of these options is probably more appropriate.
