Thank you to the kind soul who forwarded me this reference.  I haven't seen 
this article yet, but it looks interesting...

Butler, R.J. (2005). The 'fabrosaurid' ornithischian dinosaurs of the Upper 
Elliot Formation (Lower Jurassic) of South Africa and Lesotho. Zoological 
Journal (London) 145: 175-218.

Abstract: "The Upper Elliot Formation of South Africa and Lesotho contains 
the world's most diverse fauna of early Jurassic ornithischian dinosaurs.  
Nevertheless, despite four decades of work on this fauna there remains 
significant taxonomic confusion and many important specimens remain 
undescribed.  A review of the non-heterodontosaurid ('fabrosaurid') 
ornithischians of the Upper Elliot Formation is presented, following 
re-examination of all known ornithischian material from the Elliot 
Formation.  '_Fabrosaurus australis_' is based upon a single undiagnostic 
dentary, and is here considered a nomen dubium.  _Lesothosaurus 
diagnosticus_ is considered to be valid and is rediagnosed based upon a 
unique combination of plesiomorphic and derived characteristics. 
_Stormbergia dangershoeki_ gen. et. sp. nov. is described from three partial 
skeletons including numerous postcranial material.  _Stormbergia 
dangershoeki_ is significantly larger than previously described Elliot 
Formation ornithischians, and can be recognized on the basis of a unique 
combination of characters, the most important of which is the possession of 
a distinctive tab-shaped obturator process on the ischium.  A preliminary 
systematic analysis is presented, the results of which differ significantly 
from other recent ornithischian phylogenies."
