Fig. 3. Passerine groups known from Riversleigh's Cenozoic assemblages and their interrelationships, based on the time-calibrated phylogeny of Selvatti et al. (2015). Thick horizontal bars indicate the earliest temporal occurrences of passerine groups in the Riversleigh faunal assemblages, based on Boles (1999, 2005), Nguyen et al. (2013, 2014, 2016), and Nguyen (2016). The estimated age ranges of the Riversleigh Faunal Zones and the Rackham's Roost Local Fauna are from Archer et al. (1989), Creaser (1997), Travouillon et al. (2006), Arena et al. (2015), and Woodhead et al. (2016). Abbreviations: FZ A, Faunal Zone A (late Oligocene, 28.0–23.03 Ma); FZ B, Faunal Zone B (early Miocene, 23.0–16.0 Ma); FZ C, Faunal Zone C (middle Miocene, 16.0–11.6 Ma); RR, Rackham's Roost Local Fauna, Rackham's Roost Site, Riversleigh (early Pleistocene, 2.7–1.1 Ma).
