Karamuru not a valid taxon[edit]

I've done some digging and this is what I've gathered so far. "Karamuru" is based on a skull (88cm long including lower jaw) and a presacral vertebrae with articulated osteoderms originally described by Barberana (1978) catalogued as UFRGS 0156-T. To find out its phylogenetic position, Parrish, 1993 scored it and the holotype of Prestosuchus chiniquensis as separated terminal taxa and found both specimen indistinguishable from each other, he then assigned UFRGS 0156-T to P. chiniquensis. This was challenged by Kislatch (2000) which proposed a set of autopomorphic features as said in Langer et al. (2007) and erected the taxon Karamuru vorax for this specimen but it seems Kislatch never made a proper proposal of this name, like in which paper did he named it? no one seems to know, rendering it pretty much a nomen nudum, this hypothesis by Kislatch (2000) seems to have been overturned by the phylogenetic analysis of Nesbitt (2011) which along with a new, pretty much complete specimen catalogued UFRGS 0152-T, ended up indistinguishable from each other; they formed a polytopomy when scored as separate taxa and retained the same position in the analysis even when combined as a single OTU.

Thoughts? should we merge this page with Prestosuchus? Mike.BRZ (talk) 23:14, 11 May 2013 (UTC)
