The type consists of a partial skeleton in a block of sandstone, 

 in which the following portions are displayed: Eleven dorsal and six 

 caudal vertebrae, a few ribs and some abdominal ribs, part of the 

 right scapula, both ilia, the right pubis and ischium, the right femur 

 and fibula, tarsus and pes. The bones are only partly preserved, 

 and the ends are imperfectly ossified. 



In his 1911 paper Broom placed the form in a new genus on the 

 following grounds. -"Among the chief characteristics of this new 

 genus the most noteworthy is the remarkable shape of the ilium. 

 The iliac crest has a greater anterior extension than in any other 

 known carnivorous Dinosaur, and the preacetabular process is rela- 

 tively small. The femur is relatively stout, and has the trochanter 

 quartiis small and high up, and the trochanter major almost rudimentary". 



The animal is of the same size as Thecodontosaurns skirtopodus. 

 The ungual phalanges of the foot seem to be shorter than in that 

 species, but the general proportions of the remainder of the foot are 

 very similar.

The form is a small one, the type consisting of the larger portion 

 of an animal exhibited on a slab and counter-slab of sandstone. 



A portion of the left maxillary and left dentary is preserved. 

 The crowns of the teeth are broad, flat, and have the edges serrated. 

 The number of dorsal vertebrae is probably 14, and possibly 15. 

 There are certainly two sacral vertebrae, and possibly a third. Van 

 Hoepen says of the type "As appears from many loose sutural 

 connections, our animal is a young individual, and has not yet 

 reached the stage of life in which it possesses a true third sacral 

 vertebra." The shoulder girdle is described as consisting of two 

 scapulae and two coracoids. The coracoid has a supracoracoid 

 foramen, which is fairly large and close to the middle of the scapular
