Such work has significantly refined hypotheses regarding the phylogenetic and biogeographic histories of many Gondwanan vertebrate clades (e.g., fishes- Gottfried and Krause, 1998;crocodyliforms-Buckley and Brochu, 1999;Buckley et al, 2000;Turner, 2004;mammals-Jacobs et al, 1988;Bonaparte, 1990;Brunet et al, 1990;Krause et al, 1997Krause et al, , 2003and dinosaurs-Jacobs et al, 1993;Sereno et al, 1994Sereno et al, , 1996Sereno et al, , 1998Sereno et al, , 2004Russell, 1996;Sampson et al, 1998Sampson et al, , 2001Forster, 1999;Curry, 2001;Curry Rogers and Forster, 2001;…”
