"Prestosuchus" loricatus as "Abaporu" loricatus, but this name was never formalized and has not been used since. In the same paper, several Prestosuchus specimens, including the paralectotype of P. chiniquensis and the "Porto Alegre specimen" (i.e. UFRGS-PV-0156-T), were named as a different new genus, "Karamuru vorax". However, this name was also poorly defined and never formalized, so "Karamuru vorax" is considered a nomen nudum along with "Abaporu" loricatus. Porto Alegre specimens Four specimens are stored at the Universidade Federal do Rio Grande do Sul (UFRGS) in Porto Alegre. The first to be described was UFRGS-PV-0156-T, a massive and well-preserved skull discovered along with most of a vertebral column at the Pascual Sanga outcrop in Candelária. It was originally described by Barberena (1978) and has experienced much discussion as to its relations to the original Munich specimens. A more complete partial skeleton from Vale Verde, UFRGS-PV-0152-T, was studied by Nesbitt (2011) along with the Munich lectotype and UFRGS-PV-0156-T. It is anatomically similar to the latter specimen but has yet to be fully described. The most complete UFRGS specimen is UFRGS-PV-0629-T, a partial skeleton from Dona Francisca which was originally described in a thesis by Mastrantonio (2010). This specimen has been the subject of skull and braincase descriptions, as well as hip muscle reconstructions. The least complete UFRGS specimen is UFRGS-PV-0473-T, an isolated braincase which may be from the “Posto de Gasolina” outcrop in Dona Francisca. Porto Alegre has one additional Prestosuchus specimen unaffiliated with the UFRGS: MCP-146, a portion of the hip area stored at the Museu de Ciências e Tecnologia of Pontífícia Universidade do Rio Grande do Sul. Other specimens Various other museums have their own Prestosuchus specimens. One of the most spectacular specimens, ULBRA-PVT-281, consists of a very large and complete skull and partial skeleton discovered at "Posto de Gasolina" and now stored at the Universidade Luterena do Brasil (ULBRA) in Canoas. This specimen was discovered in 2010 and was fully described by Roberto-Da-Silva et al. (2018/2019) The Museu Paleontológico e Arqueológico Walter Ilha in São Pedro do Sul has a selection of Prestosuchus fossils collectively termed CPEZ-239b. CPEZ-239b corresponds to at least two juvenile individuals found at the Baum (Tree) Sanga outcrop, which were described by Lacerda et al. (2016). The only Prestosuchus fossil stored outside of Brazil or Germany is MCZ 4167, an obscure and fragmentary specimen found at "Posto de Gasolina". Stagonosuchus nyassicus is a loricatan
