“…antiquus was found in the Hawkesbury Sandstone at the former Brookvale Brick Quarry, New South Wales, Australia (Schram, 1984). The Hawkesbury Sandstone overlies the Narrabeen Group and underlies the Wianamatta Group (Herbert, 1997). Sequence stratigraphy places the Hawkesbury in Sequence F, including the appearance of Aratrisporites parvispinosus spores (Helby, 1973;Herbert, 1997).…”

Fossil age data and molecular sequences are increasingly combined to establish a timescale for the Tree of Life. Arthropods, as the most species-rich and morphologically disparate animal phylum, have received substantial attention, particularly with regard to questions such as the timing of habitat shifts (e.g., terrestrialisation), genome evolution (e.g., gene family duplication and functional evolution), origins of novel characters and behaviours (e.g., wings and flight, venom, silk), biogeography, rate of diversification (e.g., Cambrian explosion, insect coevolution with angiosperms, evolution of crab body plans), and the evolution of arthropod microbiomes. We present herein a series of rigorously vetted calibration fossils for arthropod evolutionary history, taking into account recently published guidelines for best practice in fossil calibration. These are restricted to Palaeozoic and Mesozoic fossils, no deeper than ordinal taxonomic level, nonetheless resulting in 79 fossil calibrations for 101 clades. This work is especially timely owing to the rapid growth of molecular sequence data and the fact that many included fossils have been described within the last five years. This contribution provides a resource for systematists and other biologists interested in deep-time questions in arthropod evolution.

“…Sedimentary successions immediately above the uppermost coals are generally dominated by thick sandstones that suggest persistence of active braided river systems, but the contained fossils indicate a wholesale turnover in the region's vegetation with evidence of drying and/or warming of the climate (Retallack, 2002). Slightly higher in the succession, around the position of the assumed Permian-Triassic boundary, typical redbed facies are extensively developed in all eastern Australian basins (Jensen, 1975;Herbert, 1997) and these generally persist through the Early Triassic interspersed with pulses of quartzose sands derived from the craton to the west. Sedimentation through the Permian-Triassic transition in eastern Australia essentially occurred in non-marine settings, although Uren (1980) suggested an estuarine influence in beds around the Permian-Triassic boundary in the Sydney Basin, and Naing (1990) and Herbert (1997) reported marine influences on sedimentation in that area based on ichnology and sequence stratigraphical analysis.…”

However, in Western Australia a significant transgression began toward the end of the Changhsingian, coinciding with the beginning of the Protohaploxypinus microcorpus Palynozone (Figure 14).…”

This paper presents an overview of the space and time distributions of Lopingian strata and biotas in Australia, New Zealand, Timor and New Caledonia. Based on this review, we propose a new schematic Late Permian (Lopingian) regional palaeogeographical reconstruction and marine palaeobiogeographical synthesis. The latter also incorporates some key features of the ocean circulation patterns around southeastern Gondwana, inferred primarily from the distribution of regional marine Lopingian faunas.Across Australasia, Lopingian successions accumulated in a wide range of tectonic, palaeoenvironmental and palaeolatitudinal settings. In New Zealand, Lopingian strata are found in several tectonostratigraphical terranes, notably the Brook Street, Dun Mountain–Maitai, Caples, Waipapa and Torlesse terranes/superterranes, each originating as a distinctive basin, island arc or ocean ridge. For the most part, these successions represent displaced segments of volcanic arcs, arc‐flanking clastic aprons, intra‐ and fore‐arc basins and accretionary complexes, some of which have been traced via stratigraphical, biostratigraphical and petrological correlations into New Caledonia and eastern Australia. This spectrum of Lopingian tectono‐sedimentary environments in New Zealand is interpreted to have been originally located near northeastern Australia on a convergent continental margin (i.e. the Panthalassan margin of southeastern Gondwana). Brachiopod and bivalve faunas occur widely throughout the Lopingian successions of New Zealand and have been closely studied. A total of five successive faunal zones are recognized, ranging in age from mid‐late Wuchiapingian to the end of the Changhsingian.In Australia, Lopingian deposits are dominated by non‐marine successions in a large number of widely distributed sedimentary basins; onshore exposures of marine deposits are known only from the Gympie Terrane in eastern Australia and the Canning and Bonaparte basins in Western Australia. Lopingian terrestrial sediments are most extensively represented in eastern Australia within a major meridional foreland basin complex (the Tasmania, Sydney, Gunnedah and Bowen basins), for which the evolution through the Lopingian and Early Triassic was governed by the dynamics of the New England Orogen along the Panthalassan margin of southeastern Gondwana. Most of the non‐marine successions in eastern Australia are rich in coal measures and plant fossils and locally contain well‐preserved non‐marine invertebrate and vertebrate fossils. A succession of six palynostratigraphical zones has been recognized in eastern Australia spanning the Lopingian through the Early Triassic. Several of these palynozones have also been recognized in Western Australia, allowing the discrimination and correlation of Lopingian deposits in both onshore and offshore successions. In contrast to eastern Australia and New Zealand, the marine Lopingian successions of Western Australia and Timor are dominated by carbonates that are only locally interbedded with siliciclastic sediments and sparse volcaniclastics; these successions accumulated in a giant sedimentary basin located on a passive and actively rifting continental margin. Marine connections and free and frequent biotic interchanges between this Western Australian superbasin (including Timor) and the Himalayan region of Nepal, southern Tibet and northern India throughout the Lopingian are evident from the shared occurrences of many shallow‐marine invertebrate species.

“…Unfortunately, local municipal councils in the Sydney area were not able to provide records about the age of the seawalls around the Harbour, but it may be presumed that they have been exposed to weathering agents for many decades. In contrast, rocky shores in Sydney, which originated in the Triassic period, about 200 million years ago (Herbert, 1997;Standard, 1969), have been exposed to external agents for a much longer period of time. Therefore, it could be expected that differential weathering between rocky shores and seawalls may have produced differences in important attributes of the substratum, such as roughness, porosity and/or altered chemical composition.…”
