Watongia is an extinct genus of non-mammalian synapsids from Middle Permian of Oklahoma. Only one species has been described, Watongia meieri, from the Chickasha Formation.^[1] It was assigned to family Gorgonopsidae by Olson^[1] and to Eotitanosuchia by Carroll.^[2] Reisz and collaborators assigned the genus in Varanopidae. Based on comparisons of its vertebrae with other varanopids, it was the largest varanopid with a body length of approximately 2 metres (6 ft 7 in).^[3] It was a contemporary of its closest relative, the much smaller Varanodon; the two may possibly represent growth stages of a single animal.^[4]
