I was wonderingÂif anyone had a pdf of Van Heerden's unpublished dissertation, which contains the naming and description of "RoccosaurusÂtetrasacralis" (later identified as a specimen of
Melanorosaurus readi). The full citation is below.
Van Heerden, J. (1977). The comparative anatomy of the postcranial skeleton and the relationships of the South African Melanorosauridae (Saurischia: Prosauropoda) [Unpublished doctoral dissertation]. University of the Orange Free State.ÂÂ
