Early Triassic (Induan–Olenekian) conodont biostratigraphy, global anoxia, carbon isotope excursions and environmental perturbations: New data from Western Australian Gondwana

Abstract

22The Early Triassic Induan-Olenekian Stage boundary (Dienerian-Smithian Sub-Stage 23 boundary) has been identified at a depth of 2719.25 m in the petroleum exploration well 24Senecio-1 located in the northern Perth Basin, Western Australia. Conodont faunas represent 25

Early Triassic (early Olenekian) life in the interior of East Gondwana: mixed marine–terrestrial biota from the Kockatea Shale, Western Australia

“…In the subsurface, the unit encompasses uppermost Permian to more widespread Induan intervals, in places preserving the Permian-Triassic boundary (Thomas et al, 2004;Metcalfe et al, 2008Metcalfe et al, , 2013. Strata exposed at the basin margins appear to represent the upper part of the formation, based on Olenekian ammonoids from some localities (Edgell, 1964;Skwarko and Kummel, 1972).…”

A new high-resolution δ13C record for the Early Triassic: Insights from the Arabian Platform

“…Numerous fluctuations are seen in the L'Om Picol record in Italy (Horacek et al, 2007a) where terrigenous siliciclastics are present within the Dienerian Campil Member, but the direct relationship to lithology is unclear. Elsewhere, however, the end-Dienerian excursion can be seen as a single peak (e.g., Dajiang and Dawen, S. China: Meyer et al, 2011) or a plateau (e.g., Western Australia; Metcalfe et al, 2012).…”

The Mesozoic megafossil genus Linguifolium Arber 1917

“…Temperatures in the Early Triassic were elevated globally; equatorial temperatures exceeded the tolerance threshold of many plant and animal groups, resulting in sustained suppression of the ecosystem, but conditions at higher latitudes were more equable (Sun et al 2012, 2013, Metcalfe et al 2013, Haig et al 2015. The extreme climate resulted in a global 'coal gap' through the Early Triassic (Retallack et al 1996, Metcalfe et al 2015.…”
