Genus: Koolasuchus WARREN, RICH & VICKERS-RICH, 1998
Etymology: In honor of Lesley Kool who found some of the material and prepared most of it. The generic name also, fortuitously, referes to the (preseumed) cool climate conditions present at the time of preservation, and Greek, souchos, "crocodile," a commonly used name for temnospondyls because their bodies are similar in shape to that of crocodiles.

Species: cleelandi WARREN, RICH & VICKERS-RICH, 1998
