Шаблон:Short description Шаблон:Italic title Шаблон:Taxobox 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 Шаблон:Convert,[3] while smallest species, B. mitchelli is estimated to have had a length of about Шаблон:Convert.[4]

Description

The 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]

Paleoecology

Along with other rhizodonts, Barameda seems likely to have been a benthic ambush predator, and its pectoral fins support that interpretation.[5]
