Actinopterygii are the most speciose living vertebrate clade, and study of fossil members during their Palaeozoic rise to dominance has a long history of descriptive work. Although research interest into Palaeozoic actinopterygians has increased in recent years, broader patterns of diversity and diversity dynamics remain critically understudied. Past studies have investigated macroevolutionary trends in Palaeozoic actinopterygians in a piecemeal fashion, variably using existing compendia of vertebrates or literature-based searches, and there is no comprehensive occurrence-based dataset of actinopterygians spanning the whole of the Palaeozoic. Past studies typically show low levels of diversity in the Devonian with a substantial rise in the early Carboniferous in the aftermath of the end-Devonian mass extinction. However there are unresolved patterns reported for the later Carboniferous and Permian. In large part, these conflicts span from a lack of publicly-available occurrence data: actinopterygians are majorly underrepresented in the Paleobiology Database (PBDB), for example, obscuring patterns of diversity through time. This is exacerbated by major taxonomic problems pervading the Palaeozoic actinopterygian record. Innumerable taxa are lumped into wide-ranging families and poorly-formulated genera, with a vast number of described species concentrated in several particularly problematic ‘waste-basket’ genera. This taxonomic confusion feeds into a limited understanding of phylogenetic relationships. There is also a heavy sampling bias towards Europe and North America, with other regions underrepresented despite yielding important occurrences. Scrutiny of the extent to which spatial biases influence the record is lacking, as is research on other forms of bias. Low richness in some time periods may be linked to geological biases, while the effect of taphonomic biases on Palaeozoic actinopterygians have not yet been investigated. Efforts are already underway to both redescribe poorly defined taxa and describe taxa from underrepresented regions, helping address taxonomic issues and accuracy of occurrence data. New methods of sampling standardisation utilising up-to-date occurrence databases will be critical in teasing apart biological changes in diversity from those resulting from bias. Lastly, continued phylogenetic work will enable the use of phylogenetic comparative methods to elucidate the origins of actinopterygian biogeography and subsequent patterns of radiation throughout their rise to dominate aquatic faunas.

“…Isolated jaw elements, body impressions and scales from Famennian deposits in South Africa likely represent a single actinopterygian amid a diverse array of other fishes (Gess & Whitfield, 2020), while renewed prospecting in the contemporary Maïder Basin of Morocco has produced remains of a single articulated actinopterygian (Frey et al, 2018) amongst its well-known placoderm and chondrichthyan assemblages. New South American discoveries include evidence of a stegotrachelid actinopterygian from the Frasnian of Colombia (Olive et al, 2019), the first actinopterygian remains from the Devonian of the Parnaíba Basin of Brazil (Pais de Rezende et al, 2021), and a new circumpolar species from the Middle Devonian (Figueroa, Weinschütz & Friedman, 2021). As in other localities, nonactinopterygian fishes dominate these faunas (Janvier, 2007;Janvier & Maisey, 2010;Figueroa & Machado, 2018).…”

Actinopterygii makes up half of living vertebrate diversity, and study of fossil members during their Palaeozoic rise to dominance has a long history of descriptive work. Although research interest into Palaeozoic actinopterygians has increased in recent years, broader patterns of diversity and diversity dynamics remain critically understudied. Past studies have investigated macroevolutionary trends in Palaeozoic actinopterygians in a piecemeal fashion, variably using existing compendia of vertebrates or literature‐based searches. Here, we present a comprehensive occurrence‐based dataset of actinopterygians spanning the whole of the Palaeozoic. We use this to produce the first through‐Palaeozoic trends in genus and species counts for Actinopterygii. Diversity through time generally tracks metrics for sampling, while major taxonomic problems pervading the Palaeozoic actinopterygian record obscure diversity trends. Many described species are concentrated in several particularly problematic ‘waste‐basket’ genera, hiding considerable morphological and taxonomic diversity. This taxonomic confusion also feeds into a limited understanding of phylogenetic relationships. A heavy sampling bias towards Europe and North America exists in both occurrence databases and available phylogenetic matrices, with other regions underrepresented despite yielding important data. Scrutiny of the extent to which spatial biases influence the actinopterygian record is lacking, as is research on other forms of bias. Low richness in some time periods may be linked to geological biases, while the effects of taphonomic biases on Palaeozoic actinopterygians have not yet been investigated. Efforts are already underway both to redescribe poorly defined taxa and to describe taxa from underrepresented regions, helping to address taxonomic issues and accuracy of occurrence data. New methods of sampling standardisation utilising up‐to‐date occurrence databases will be critical in teasing apart biological changes in diversity and those resulting from bias. Lastly, continued phylogenetic work will enable the use of phylogenetic comparative methods to elucidate the origins of actinopterygian biogeography and subsequent patterns of radiation throughout their rise to dominate aquatic faunas.

“…Olive et al . [ 2 ] have hypothesised a western European (Euramerican) origin for tristichopterids, suggesting that they migrated from Western Europe to Australia as part of the Late Devonian faunal exchange between Euramerica and Gondwana. Thereafter they suggest that a highly nested clade of giant Late Devonian tristichopterids, comprising Cabonnichthys burnsi [ 3 ], Mandageria fairfaxi [ 4 ], Eusthenodon wangsjoi [ 5 ], Edenopteron keithcrooki [ 6 ], and Hyneria lindae [ 7 ] most likely differentiated in Australia.…”

We describe the largest bony fish in the Late Devonian (late Famennian) fossil assemblage from Waterloo Farm near Makhanda/Grahamstown, South Africa. It is a giant member of the extinct clade Tristichopteridae (Sarcopterygii: Tetrapodomorpha) and most closely resembles Hyneria lindae from the late Famennian Catskill Formation of Pennsylvania, USA. Notwithstanding the overall similarity, it can be distinguished from H. lindae on a number of morphological points and is accordingly described as a new species, H. udlezinye sp. nov. The preserved material comprises most of the dermal skull, lower jaw, gill cover and shoulder girdle. The cranial endoskeleton appears to have been unossified and is not preserved, apart from a fragment of the hyoid arch adhering to a subopercular, but the postcranial endoskeleton is represented by an ulnare, some semi-articulated neural spines, and the basal plate of a median fin. The discovery of H. udlezinye shows that Hyneria is a cosmopolitan genus extending into the high latitudes of Gondwana, not a Euramerican endemic. It supports the contention that the derived clade of giant tristichopterids, which alongside Hyneria includes such genera as Eusthenodon, Edenopteron and Mandageria, originated in Gondwana.
