The theropod from the Tahora Formation would have been bipedal and likely carnivorous. Because of the lack of material, its exact taxonomic placement is uncertain, although its discoverer Joan Wiffen considered it possibly a megalosaurid, at the time a poorly defined group of unspecialized large carnivorous dinosaurs. The vertebra was described by Molnar (1981), and was considered an indeterminate theropod by Agnolin et al.
