Description and Remarks— The one specimen attributed to the fossil otolith-based Genartina is similar to Genartina sp. 1 reported and illustrated by Schwarzhans and Stringer (2020a). The specimen is high-bodied, somewhat discoid in shape (sensu Smale et al. 1995), thin and flat, a gentle and deeply curved ventral margin, and a short, pointed rostrum (which is often broken). The sulcus is slightly dorsal with a much longer, tapering cauda and a somewhat oval ostium. The Arkadelphia specimen resembles G. abbatiae ( Stinton, 1965) from the European Paleocene and early Eocene (see under “ Harpadontina ” abbatiae in Nolf 2013, pl. 58). The specimen also somewhat resembles G. texana Dante and Frizzell (1965) described from the Eocene of the USA Gulf Coastal Plain ( Frizzell and Dante 1965). Schwarzhans and Stringer (2020) noted that Genartina has a relatively large stratigraphic range from Late Cretaceous (Santonian) to middle Eocene (Bartonian). Its taxonomic assignment has been greatly debated and included the Osteoglossiformes Regan (1909) ( Frizzell and Dante 1965), Osmeridae Forey(1973) ( Nolf1985), Elopiformes (including Albuliformes ) in Schwarzhans (2003, 2012), Harpodontidae Bleeker (1875) ( Nolf 2013), Synodontidae Gill (1861) ( Stringer et al. 2016), and Stomiiformes Fink and Weitzmann (1982) ( Schwarzhans et al. 2018b). Schwarzhans and Stringer (2020a) proposed that Genartina probably belongs to an extinct family and order of bony fishes and placed it after the Albuliformes .
