"The abelisaurid Abelisaurus comahuensis was long thought to come from the Anacleto Formation, from sedimentary beds near Pellegrini Lake (Heredia and Salgado 1999; Leanza et al., 2004). However, a recent communication referred Abelisaurus to the lower member of the Allen Formation (Delaloye and Garrido 2017). Nonetheless, Giannechini et al. (2015), following information from local farmers, raised the possibility that the Abelisaurus holotype does not come from Pellegrini Lake, and instead, belongs to a farm close to Salitral Moreno in which continental sediments from Allen Formation outcrops; however, as pointed out these authors there is no record or field notes to assert this line of evidence (Aranciaga Rolando et al. 2020). |
