R. B. J. Benson 2008 | Tyrannosauroid theropod differing from other tyrannosauroids due to the following autapomorphic characters of the ilium: blade with semi-oval outline in lateral view; narrow preacetabular notch; distinct, posterodorsally inclined, vertical ridge on lateral surface dorsal to acetabulum developed as ‘corrugated’ structure with a complementary groove following the corresponding structure on the medial face. |
