 The hip is quite small compared to their long legs.The femur (thigh bone) is more than 1.3 times the length of the ilium (upper plate-like bone of the hip) in members of this subfamily, while most other ceratosaurians have shorter legs and a femur approximately the same length of the ilium.The connection between the ilium and the pubis (forward-projecting rod-like lower bone of the hip) is also more simple than in other ceratosaurians.
