An excerpt from the paper describing Lajasvenator identifies Taurovenator as a synonym of Mapusaurus: "Taurovenator violantei (Motta et al., 2016) is a recently described carcharodontosaurid taxon based on an isolated right postorbital. The autopomorphies proposed to support this taxon consist of the presence of a horn-like prominence on the orbital brow, and a deep excavation on the ventral surface of the postorbital. However, these features are present in Mapusaurus (MCF-PVPH-108.177) and, although less developed, are also in Giganotosaurus (MUCPv-CH-1). The holotype specimen MPCA PV 802 of Taurovenator also exhibits the ventrolateral curved lateral margin of the palpebral (Motta et al., 2016, figs. 4 and 5), a diagnostic feature proposed for Mapusaurus roseae (Coria and Currie, 2006). Considering that the holotype specimen of Taurovenator (MPCA PV 802) was collected at the same stratigraphic level as Mapusaurus (Huincul Formation), and that there are no further autopomorphies in that single postorbital, it seems more reasonably to consider Taurovenator violantei as junior synonym of Mapusaurus roseae." - 1morey August 8, 2020 2:22 PM (EST) — Preceding unsigned comment added by 1morey (talk • contribs)
