Summary of the phylogeny and geographic distribution of Oreosaurus (Sánchez-Pacheco et al. 2017). SNSM = Sierra Nevada de Santa Marta, Colombia; TCM = tepuis from the Chimantá massif, Venezuela; CCC = Cordillera de la Costa Central, Venezuela; IT = island of Trinidad; CCO = Cordillera de la Costa Oriental, Venezuela. Oreosaurus luctuosus, from the CCC, and O. rhodogaster, from the CCO, were included in this genus due to the presumed close relationships of these species and O. achlyens and O. shrevei, respectively. Data taken from Sánchez-Pacheco et al. (2017).
