“…A diverse Frasnian microvertebrate fauna has also been recorded by Trinajstic and George (2009) with scales of the thelodont Australolepis seddoni Turner and Dring, 1981 recorded as occurring with conodont elements and phoebodont teeth for the first time, thus allowing the age of A. seddoni to be constrained to MN 4-10 CZ. The phoebodont teeth were also correlated to the known phoebodont based zonation of Ginter and Ivanov (1995a).…”

Where known, the Devonian shark fauna of Western Australia (Trinajstic and George 2009;Trinajstic et al 2014) has been correlated to the Frasnian phoebodont zonation of Ginter and Ivanov (1995a).

A diverse microvertebrate fauna is described from the Virgin Hills and Napier formations, Bugle Gap Limestone Canning Basin, Western Australia. Measured sections at Horse Spring and Casey Falls (Virgin Hills Formation) and South Oscar Range (Napier Formation) comprise proximal to distal slope carbonates ranging in age from the Late Devonian Frasnian to middle Famennian. A total of 18 chondrichthyan taxa are identified based on teeth, including the first record of Thrinacodus tranquillus, Cladoides wildungensis, Protacrodus serra and Lissodus lusavorichi from the Canning Basin. A new species, Diademodus dominicus sp. nov. is also described and provides the first record of this genus outside of Laurussia. In addition, the upper range of Australolepis seddoni has been extended to Late Devonian conodont Zone 11, making it the youngest known occurrence for this species. The Virgin Hills and Napier formations microvertebrate faunas show close affinities to faunas recovered from other areas of Gondwana, including eastern Australia, Iran, Morocco and South China, which is consistent with known conodont and trilobite faunas of the same age.

ABSTRACT:Ginter, M., Gouwy, S. and Goolaerts, S. 2017. A classic Late Frasnian chondrichthyan assemblage from southern Belgium. Acta Geologica Polonica, 67 (3), 381-392. Warszawa.Samples from the Upper Frasnian (Devonian) of Lompret Quarry and Nismes railway section in Dinant Synclinorium, southern Belgium, yielded several chondrichthyan teeth and scales. The teeth belong to three genera: Phoebodus, Cladodoides and Protacrodus. The comparison with selected Late Frasnian chondrichthyan assemblages from the seas between Laurussia and Gondwana revealed substantial local differences of taxonomic composition due to palaeoenvironmental conditions, such as depth, distance to submarine platforms, oxygenation of water, and possibly also temperature. The assemblage from Belgium, with its high frequency of phoebodonts, is the most similar to that from the Ryauzyak section, South Urals, Russia, and the Horse Spring section, Canning Basin, Australia.
“…thomasi Turner resulted in its identification as Cladodoides wildungensis Jaekel. Ginter and Ivanov (1995) proposed a zonal scale based on Phoebodus representatives, which was tested in many regions of the world. The investigations in the Kuznetsk coal basin made it possible to specify this scale (Ivanov and Rodina, 2002), which is now accepted as a zonal scale on sharks (Becker et al, 2012).…”

The thorough investigation of four Frasnian-Famennian (Upper Devonian) boundary sections along the right side of the Tom River northwest of Kemerovo yielded new data on the composition of their foraminiferal and ichthyofaunal assemblages. These data were used for development of the zonal foramin iferal scale for Upper Devonian deposits of the northwestern Kuznetsk coal basin and the first zonal scale for their subdivision on the basis of Elasmobranchii remains and for correlation of the examined sections between each other and with Upper Devonian sequences in other regions. The analysis of foraminiferal and ichthyofaunal assemblages, which are the most widespread in upper Frasnian sections of the northwestern Kuznetsk coal basin, made it possible to specify the regional stratigraphic model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
