Ebenaqua
''Ebenaqua'' (from Latin ''ebenus'' ("black") + ''aqua'' ("water"), referencing the type locality) is an extinct genus of freshwater bobasatraniiform ray-finned fish that lived during the Lopingian (late Permian) epoch of Australia. It contains a single species, ''E. ritchiei'', known from the Changhsingian-aged Rangal Coal Measures of what is now Blackwater, Queensland, Australia.

Bobasatraniiformes
Bobasatraniiformes is an extinct order of durophagous ray-finned fish that existed from the late Permian to the Middle Triassic in both marine and freshwater environments. The order includes two families: Bobasatraniidae, with the genera ''Bobasatrania'', '' Ebenaqua'', and '' Ecrinesomus'', and Dorypteridae, comprising only the genus '' Dorypterus'' (monotypy). Bobasatraniiformes had a somewhat global distribution; fossils are found in Africa (Madagascar), Asia (Pakistan), Australia, Europe, and North America. Most bobasatraniiforms were small or less but some species of ''Bobasatrania'' grew up to long or larger. Bobasatraniiformes have a deepend body, a heterocercal caudal fin, and they often lack pelvic fins (present in ''Dorypterus'', very small in ''Ebenaqua''). Their dorsal and anal fins are often elongate (very elongate dorsal fin in ''Dorypterus''). The body is covered in rhombic scales (scale cover reduced in ''Dorypterus''). Their jaw bones lack teeth.
