Barameda (Indigenous Australian language: "fish trap" [1] ) is a genus of rhizodont lobe-finned fishes which lived during the Tournaisian stage near the start of the Carboniferous period in Australia; fossils of the genus have been reported from the Snowy Plains Formation. [2] The largest member of this genus, Barameda decipiens, reached an estimated length of around 3–4 metres (9.8–13.1 ft), [3] while the smallest species, B. mitchelli is estimated to have had a length of about 35 centimetres (14 in). [4]
Species of the genus Barameda had an extremely elongated and thick body typical of Carboniferous rhizodonts. It was covered with moderately thin, cycloidal scales, [1] with thick bony plates covering its head and operculum (gill flaps), a tightly fused Skull roof, and extremely prominent, sharp fangs, devoid of serrations or cutting edges. Its scales preserved a lateral line. [2] Originally it was estimated to have a typical narrow pectoral fin, however a later study shows that it had a wider pectoral fin like other Carboniferous rhizodonts. [5]
Along with other rhizodonts, Barameda seems likely to have been a benthic ambush predator, and its pectoral fins support that interpretation. [5]
