is known only from a partial mandible, a partial pelvis, an incomplete hindlimb, a partial sacrum, and most of the caudal series from the Late Cretaceous of Mongolia (Osmólska 1996). It is apomorphic in its two caudal surangular foramina and stout hyposphene-hypantrum articulations in the first 16 caudals. As in some ceratosaurs and birds, the astragalus and calcaneum are fused to each other and to the tibia; furthermore, the distal portion of the fibula is fused to the tibia and tarsus. Osmólska (1996) did not attempt a phylogenetic analysis of this taxon but hypothesized that it was the sister taxon to

, and hence a basal tyrannosauroid, as well as to related taxa based on the following derived features: a prominent and laterally extending horizontal shelf on the lateral surface of the surangular, rostral and ventral to the mandibular condyle; the retroarticular process reduced and broadened; and a ventral flange on the ischial peduncle of the pubis. However, given the fragmentary nature of this taxon and the incomplete nature of what is known of
