Proterozoic and Early Cambrian trace fossils from the Amadeus and Georgina Basins, central Australia

Ediacara fossil assemblage in the upper Vindhyans of Central India and its significance

“…A large diversity of Ediacaran organisms and forms resembling them are known from 32 countries including some other parts of Australia (Walter et al, 1989;Cruse and Harris, 1994), the Nama Group of Namibia (Crimes and Germs, 1982;Narbonne et al, 1997), the Charnian Supergorup of England (Boynton and Ford, 1979), the Dividal Group of Norway (Føyn and Glaessner, 1979), the San Vito Series of Sardina (Debrenne and Naud, 1981), South Wales (Cope, 1983), Finnmark (Farmer et al, 1991), Podolia (Fedonkin, 1983a,b;Velikanov and Gureev, 1983), Siberia (Sokolov, 1976), Olenek Uplift (Sokolov and Fedonkin, 1984;Fedonkin, 1990), Middle Urals (Becker, 1990), China (Chen, 1991), Avalon Peninsula of Newfoundland (Anderson and Conway Morris, 1982), NW Canada and British Columbia (Narbonne and Hofmann, 1987;Hofmann et al, 1991;Narbonne and Aitken, 1990), North Carolina (Gibson et al, 1984), Southern Nevada (Horodyski, 1991) and India (De, 2003). Factors promoting soft-body preservation of the Vendian biota are higher benthic population density in active hydrodynamic zones of shallow water epiplatform seas or platform edges with coarse lamellar terrigenous substrates, higher percentage of attached forms, low activity level of scavengers and vagile predators, little processing of sediments by deposit feeders, stabilization of sediment by algal and cyanobacterial mats, quick burial of organisms following storm events and early rapid diagenesis (Lipps and Signor, 1992).…”

A diverse ichnofauna from the Cambrian Stage 4 Wulongqing Formation near Kunming (Yunnan Province, South China)

“…Well-preserved specimens show a central plug (probably the end part of a short vertical burrow), have a constant diameter of 5-7 mm and (if preserved as a positive hyporelief) are 2-3 mm high. Similar problematic structures have been reported from the early Cambrian of the Arumbera section (Amadeus Basin, central Australia) by Walter et al (1989). These authors compared the Amadeus basin specimens with Asterichnus isp.…”

“…The ichnogenus Diplichnites occurs in several other Cambrian shallow marine environments, e.g., in Australia (Walter et al 1983), Pakistan (Seilacher 1955), Canada (Young 1972), Spain (Crimes et al 1977) and in the Nomtsas Formation, Namibia (Crimes & Germs 1982). The youngest occurrence of Diplichnites is in the lower Permian (Walter et al 1989). Figure 10C Description and discussion.…”
