dc.description.abstractUntil recently the immediate aftermath of the Hangenberg event of the Famennian Stage (Upper Devonian) was considered to have decimated sarcopterygian groups, including lungfish, with only two taxa, Occludus romeri and Sagenodus spp., being unequivocally recorded from rocks of Tournaisian age (Mississippian, Early Carboniferous). Recent discoveries of numerous morphologically diverse lungfish tooth plates from southern Scotland and northern England indicate that at least ten dipnoan taxa existed during the earliest Carboniferous. Of these taxa, only two, Xylognathus and Ballgadus, preserve cranial and post-cranial skeletal elements and are yet to be described. Here we present a description of the skull of a new genus and species of lungfish, Limanichthys fraseri gen. et sp. nov. that hails from the very lowest Tournaisian from the Ballagan Formation of Burnmouth, southern Scotland. The new specimen represents the earliest definitive Tournaisian lungfish skull material thus providing valuable insight into the response of this group, and indeed, the Sarcopterygii as a whole, immediately following the Upper Devonian Hangenberg event. Phylogenetic analysis places Limanichthys fraseri within the Devonian ‘phaneropleurid-fleurantiid’ grade of lungfish and that the Carboniferous lungfish represent forms that have their origins deep in the Mid and Late Devonian as well as those from a unique Carboniferous radiation.
