“…This paucity of information from Gondwana may reflect a lack of appropriate marine facies, an impoverishment of endemic conodont faunas due to environmental stresses associated with an ice-sheet proximal location, or alternatively, reworking and erosion of the stratigraphical record of this interval. The impact of glaciation on conodonts is supported by the faunal observations of Dzik (1997) with respect to pulses of the Late Palaeozoic Ice Age, as well as the possible recognition of endemic conodont faunas within parts of Gondwana from this time, for example Montognathus (Jenkins et al 1993).…”

Conodonts of the genus Lochriea offer high‐resolution biostratigraphical differentiation of the upper Mississippian (Carboniferous). In particular, L. ziegleri is regarded as the most suitable index taxon for recognition of a revised Viséan–Serpukhovian boundary and selection of a Global Stratotype Section and Point. Mixed carbonate‐siliciclastic Carboniferous sections from western Ireland demonstrate that gradual morphological evolution is expressed within the Lochriea lineage, evidenced by P1‐elements with progressively more complex ornament appearing in a pulsed fashion in the Late Viséan. Significant diversification of the Lochriea conodonts occurs below the currently recognized base of the Namurian (identified by ammonoids), with which the basal Serpukhovian has been correlated in the past. The First Appearance Datum (FAD) of L. ziegleri in the Lugasnaghta Section of western Ireland is apparently coincident with the FAD's of other complexly ornamented Lochriea species (e.g. L. cruciformis) and corresponds with the Irish and British P2a ammonoid biozone and the lower part of the upper Cf6δ (MFZ15) foraminiferal biozone. The FAD of L. ziegleri in Ireland is closely related to other Lochriea morphotypes with complex ornament, which are difficult to identify to species level using current species definitions. These forms, recorded from the three sections examined (St Brendan's Well, Kilnamona and Lugasnaghta), may partly be explained as abnormal growth histories, evolutionary intermediate forms, etc. In some instances, however, the apparently consistent and novel morphotypes suggest that current Lochriea taxonomy needs to be re‐examined. Furthermore, given the close association of the morphologies with asymmetric complex ornament and L. ziegleri, these taxa may hold significance as biostratigraphical tools in their own right.

“…True arundineum is a late Viséan species, according to Denayer & Webb (2015). Percival (2010, p. 173) summarised evidence for the age of the Caroda Formation, citing Roberts et al (1993) and Jenkins et al (1993), indicating a middle Viséan age for the dated horizons. The field relationships being unclear, there is no assurance that the cited horizons are identical with that of the occurrence at "Pinaroo Plain" The age of the Halls Creek occurrence may be intermediate between that of the two previous localities, as it contains Aphrophyllum hallense Smith, tying it to Glenbawn, and Cionodendron instead of Pickettodendron, implying a younger age.…”

Settlement strategy in Symplectophyllum (Cnidaria, Rugosa)

ABSTRACT. The early ontogeny of the solitary rugose coral Symplectophyllum from the late Tournaisian -early Viséan of New South Wales is described. The genus is frequently associated with the phaceloid tabulate coral Syringopora, individuals of the former genus occurring within the coralla of the latter, and growing in tandem. A similar association also occurs between Symplectophyllum and the rugosan genera Cionodendron and Pickettodendron, though less commonly. The phaceloid genera suffer periodic mortality events, causing breaks in vertical growth; the settlement of Symplectophyllum larvae appears to be associated with these events. Larvae settle on algal incrustations of the epitheca of the phaceloid corals, not on the epitheca itself. The manner in which Symplectophyllum corallites acquired space for growth suggests the presence of sweeper tentacles in Rugosa.
