  • Stratigraphical intervals and data sources are as follows. South China: lower Floian–lower Darriwilian, Tetragraptus approximatus–Undulugraptus austrodentatus graptolite biozones (Brocke et al. 1999, 2000; Huang et al. 1994; Li 1987, 1990; Li et al. 2002b; Lu 1987; Tongiorgi et al. 1995, 1998, 2003a; Yan et al. 2011; Yin 1994). Canning Basin: Willara, Goldwyer and Nita formations, middle Floian–upper Darriwilian, Athabascaella rossii to Dactylofusa striatogranulata acritarch biozones (Playford & Martin 1984; Quintavalle & Playford 2006a, b). Georgina Basin: Coolibah Formation, middle–upper Floian (upper Bendigonian–lower Chewtonian in Zhen et al. 2003, fig. 6; Playford & Wicander 1988).
