An exceptionally well-preserved short-snouted bandicoot (Marsupialia; Peramelemorphia) from Riversleigh's Oligo-Miocene deposits, northwestern Queensland, Australia

Revision of Oligo-Miocene kangaroos, Ganawamaya and Nambaroo (Marsupialia: Macropodiformes, Balbaridae)

“…Specimens from Dirk's Tower are interpreted as belonging to Faunal Zone B by Travouillon et al (2010) and interval B1 by Arena et al (2015). Specimens from Quantum Leap Site interpreted as a Faunal Zone B assemblage by Travouillon et al (2010) and interval B2 or B3 by Arena et al (2015), are referred to Gan. gillespieae comb.…”

A New Family of Large Omnivorous Bats (Mammalia, Chiroptera) from the Late Eocene of the Fayum Depression, Egypt, with Comments on Use of the Name “Eochiroptera”

“…Among extant marsupial lineages, didelphids, dasyurids, and peramelemorphians are typically moderately to strongly dilambdodont (Archer, 1976;Travouillon et al, 2010Travouillon et al, , 2013Travouillon et al, , 2014. Marsupial dilambdodonty generally differs from that seen in bats in that the paracone and metacone are set very far lingually and the postparacrista and premetacrista are very short, producing a very broad stylar shelf and a buccolingually narrow protofossa that does not extend far onto the stylar shelf.…”

“…Additionally, parastylar and metastylar foveae are not generally developed on marsupial molars, unlike the condition that is seen in virtually all dilambdodont bats. Bandicoots are an exception to this pattern; the postparacrista and premetacrista in these marsupials are very long, sometimes extending nearly to the labial margin of the tooth crown, and parastylar and metastylar foveae are well devoloped (Travouillon et al, 2010(Travouillon et al, , 2013(Travouillon et al, , 2014. However, bandicoots have a pair of large stylar cusps flanking the labial ends of the postparacrista and premetacrista, a condition that distinguishes them from bats, which generally lack these cusps (see below).…”

“…The large stylar cusps (often labeled A through D) in marsupials are not regarded as homologous with any cusps on placental mammal teeth because they are absent in stem metatherians and eutherians (Clemens, 1966;Cifelli, 1993;Rose, 2006;Ungar, 2010). The isolated ectostyle set at the base of the parastylar fovea in Aegyptonycteris differs from stylar cusp B in most marsupials because it is not located on the labial margin the crown nor connected to the premetcrista, both of which are common morphologies in marsupials (Archer, 1976;Cifelli, 1993;Rose, 2006;Ungar, 2010;Travouillon et al, 2010Travouillon et al, , 2013Travouillon et al, , 2014.…”

“…Many marsupials have well-developed conules (Archer, 1976) that in some cases are quite large; many bandicoots, for example, are characterized by large metaconules that form a "metaconular hypocone" on the posterolingulal corner of the molar crowns (Travouillon et al, 2010(Travouillon et al, , 2013(Travouillon et al, , 2014. Presence of well-developed conules is believed to represent the plesiomorphic condition for marsupials (Archer, 1976).…”
