“…However, Seddon (1969) indicated, mainly from conodont evidence, a late Givetian and early Frasnian age (not younger than do lot) for the Sadler Limestone, and he ascribed a similar age range to the Gneudna Formation on his conodont and fish data. Subsequently, Roberts et al (1972) and Playford et ai. (1975) discounted the existence of proven Givetian faunal associations in the Sadler Limestone; this, in effect, removes or at least renders suspect the putative late Givetian component within the age of the Gneudna Formation.…”

“…Walkom (1928) regarded the macrofloral assemblage from the Yalwal Volcanics as Late Devonian. Marine invertebrates and fish fossils from the overlying Merrimbula Group are of Frasnian age (Roberts et al 1972;Webby, 1972;Young, 1993) and a Givetian-Frasnian age for the Yalwal Volcanics was suggested by Mcllveen (1975) based on the collective biostratigraphic data. Similarly, Anderson & Anderson (1985) proposed a late Middle to Late Devonian age for the faunas and comparable macrofloras of the Witteberg Group in South Africa.…”

An assemblage of fossil plants is here recorded from the Middle Devonian Beacon Heights Orthoquartzite and overlying Aztec Siltstone (Taylor Group), of the Cook Mountains and Skelton Névé regions, southern Victoria Land, Antarctica. The Beacon Heights Orthoquartzite exposed in the southern Cook Mountains yielded specimens of the lycopods Haplostigma lineare, Malanzania sp., and Archaeosigillaria sp. cf. A. caespitosa. The Aztec Siltstone flora contains Praeramunculus alternatiramus and H. lineare.

“…) that contain specimens assignable to Crurithyris apena Veevers. This is the diagnostic species of the C. apena Zone for which a Frasnian age has been established in Australia for several decades (Veevers, ; Roberts, ; Roberts et al ., ). A Frasnian age assignment is further supported by the first occurrence of the cerioid coral Argutastrea hullensis at similar stratigraphic levels in the long sections (Fig.…”

Stratal architecture and platform evolution of an early Frasnian syn‐tectonic carbonate platform, Canning Basin, Australia

et al. 2013

Facies architecture and platform evolution of an early Frasnian reef complex in the northern Canning Basin of north-western Australia were strongly controlled by syn-depositional faulting during a phase of basin extension. The margin-attached Hull platform developed on a fault block of Precambrian basement with accommodation largely generated by movement along the Mount Elma Fault Zone. Recognition of major subaerial exposure and flooding surfaces in the Hull platform (from outcrop and drillcore) has enabled comparison of facies associations within a temporal framework and led to identification of three stages of platform evolution. Stage 1 records initial ramp development on the hangingwall dip slope with predominantly deep subtidal conditions that prevented any cyclic facies arrangements. This stage is characterised by basal siliciclastic deposits and a major deepening-upward facies pattern that is capped by a sequence boundary towards the footwall (north-west) and a major flooding surface towards the hangingwall. Stage 2 reflects the bulk of platform aggradation, significant platform growth towards the hangingwall and the development of reef margins and cyclic facies arrangements. Thickening of this stage towards the hangingwall indicates that accommodation was generated by rotation of the fault block and overlying platform. Stage 3 records a major flooding and backstep of the platform margin. The Hull platform illustrates important elements of margin-attached carbonate platforms in a half-graben setting, including: (i) prominent, but limited, coarse siliciclastic input that does not have a major detrimental effect on carbonate production near the rift margin in arid to semi-arid settings; (ii) wedge-shaped accommodation created by syn-depositional rotation of fault blocks and tilting of the hangingwall dip slope, resulting in shallowwater facies and subaerial exposure up-dip of the rotational axis and deeper water facies down-dip; and (iii) evolution of a ramp to rimmed shelf, coincident with a sequence boundary-flooding surface, that is accelerated by tilting of the hangingwall dip slope during fault-block rotation.
