Brian George Gardiner PPLS was a British palaeontologist and zoologist, specialising in the study of fossil fish (palaeoichthyology).
Turseodus is an extinct genus of ray-finned fish found in Late Triassic freshwater sediments of the United States. Two species have been described, T. acutus from the Lockatong Formation of Pennsylvania, and T. dolorensis from the Chinle Formation of Colorado.
Eigil Hans Aage Nielsen was a Danish paleontologist, who specialized in fossil vertebrate anatomy, particularly of Triassic bony fish.
Kelliaichthys is an extinct genus of prehistoric bony fish that lived during the Cisuralian epoch in what is now East Kazakhstan, Kazakhstan. It was originally named "Kellia" by Kazantseva-Selezneva (1980). Because this genus name was already given to an extant lasaeid bivalve, the new name Kelliaichthys was erected for the Permian fish. The genus includes a single species (monotypy): Kelliaichthys velox.
