Brookvalia Explained

Brookvalia is an extinct genus of prehistoric freshwater ray-finned fish that lived during the Middle Triassic epoch (Anisian stage).^{[1] [2]}

It contains four species, all known from the Hawkesbury Sandstone near Brookvale, New South Wales, Australia.^{[3] [4]}

• †B. gracilis Wade, 1933 (=B. parvisquamata Wade, 1933)
• †B. latipennis (Wade, 1935) (=Dictyopleurichthys latipennis Wade, 1935)
• †B. propennis Wade, 1933
• †B. spinosa (Wade, 1935) (=Beaconia spinosa Wade, 1935)

It was a member of the redfieldiiforms, a group of presumed basal neopterygians that were widespread during the Triassic.^{[5] [6]}
