Holotype- (IVPP V636) distal end of anterior dorsal rib (92 mm wide distally, 53 proximally) This specimen was originally identified as a scapula, and later assigned to the Tyrannosauridae by Molnar et al. (1990) because of its narrow shaft. Chure, 2001 assigns it as coelurosauria indet, while others suggests its an allosaurid. The specimen is indeterminate, and not identifiable past theropoda.
