description Akmonistion Overview
Akmonistion is an extinct chondrichthyan from the Early Carboniferous, known from fossil material found at Bearsden in Scotland. It was named in 2001 and is associated with the stethacanthid group of shark-like cartilaginous fishes. The animal is particularly notable for an anvil-like dorsal fin, an unusual structure that distinguishes it from the body forms of living sharks. Akmonistion is consequently relevant to studies of early shark relatives and the diversity of Carboniferous marine life.
