Middle Palaeozoic vertebrate fossil occurrences are summarised for Australia, with reference to faunal connections between Asia and East Gondwana, as first indicated by fish distributions of Lower Devonian fossil sites. Major endemic groups discussed are pituriaspid (Australian) and galeaspid (Asian) agnathans, wuttagoonaspids (Australian) and antarctaspid (Antarctic, Australian, Asian) arthrodires, yunnanolepid and sinolepid antiarchs (South China, Indochina terrane, Australia), and early tetrapodomorphs (South China, Australia). More widespread groups that lived in shallow marine environments (lungfishes, buchanosteid arthrodires, antiarch Bothriolepis) also show species groups shared between South China and East Gondwana. Exchange of continental facies fishes (e.g. tristichopterid tetrapodomorphs) may have been interrupted by marine transgression in the Frasnian, but were restored in the late Famennian with the appearance of Grenfellaspis in eastern Australia, the only sinolepid antiarch known from outside Asia. The hypothesis of Gondwana dispersion and Asian accretion, to explain the collage of geological terranes forming modern east and southeast Asia, implies increasing dissimilarity with increasing age, but the Siluro-Devonian early vertebrate evidence is inconsistent with this. Previous cladistic analysis of Asian terranes predicted galeaspid agnathans on the Indochina terrane, and their subsequent discovery at Ly Hoa, Vietnam, confirms that Indochina and South China had come together across the Song Ma suture by Middle Devonian time.

“…This view was challenged by Packham (2003) but further supported by Durney and Hood (2003). The Talmo area lies within an unnamed syncline west of the Long Plain Fault along which, farther south, Silurian volcanic and plutonic rocks have been thrust east over the mainly Emsian Devonian Hatchery Creek Group (Hunt & Young, 2012) in the Wee Jasper Syncline adjacent to the Taemas-Black Range Synclinorium ( Figure 2). A significant feature of these regional folds, where the succession contains competent volcanic units, is that they have gentle plunges and this is well illustrated by common gentle north dips around the southern closure of the Yass Syncline .…”

Volcanic rocks are widespread in middle Silurian to Lower Devonian rocks of the Lachlan Orogen in southeastern Australia. In the Yass-Canberra region, the Silurian succession consists of two S-type dominantly ignimbrite suites with the lower Hawkins/Goobarragandra and upper Laidlaw volcanics separated and overlain by clastic-carbonate intervals, and unconformably overlain by Lower Devonian silicic volcanic rocks. In the Talmo area, 30 km west of Yass, the Goobarragandra Volcanics are overlain by a clastic-carbonate succession of the Talmo Formation, which has a partly faulted boundary with the Lower Devonian Mountain Creek Volcanics containing rheomorphic welded ignimbrites. The contact of the Mountain Creek Volcanics and the Talmo Formation coincides with the margin of a prominent ovoid gravity low. Dip patterns in the Talmo Formation indicate two orientation domains divided by a northwest-trending faulted boundary. The domain to the southwest consists of gently northeast-dipping interbedded limestone and mudstone whereas the domain to the northeast has steep to moderate dips to the south and southeast with interbedded limestone and mudstone overlain by massive mudstone and quartz-rich turbidites. These contrasting domains are interpreted as a result of subsurface differential downsag, possibly a caldera, accommodated by downwarping in the adjacent Talmo Formation and accompanied by movements across a northwest-trending fault and potential ring faults.
