Sachicasaurus vitae was named by Páramo-Fonseca et al. (2018) [Sachicasaurus vitae (MP111209-1) is a brachauchenine pliosaurid characterized by two autapomorphies: a very short mandibular symphysis ending at the mid length of the fourth mandibular alveoli and highly reduced number of mandibular teeth (17-18). It is distinguished from all other pliosaurid, except L. itilensis in having an ilium with a long posterior projection. It differs from all other brachauhenines in having a pineal foramen in a very anterior position (similar to L. itilensis) and cervical centra without dorsal but with ventral foramina. Sachicasaurus vitae is also distinguished from other bracauchenines by the following unique combination of characters: skull exceeding two meters in length (as in K. queenslandicus and “K.” boyacensis), lateral expansion of the maxilla posterior to the premaxilla-maxilla suture (unlike B. lucasi), premaxilla with four teeth (unlike in L. itilensis), caniniform teeth present (as K. queenslandicus and “K.” boyacensis), dental sequence showing only two non-contiguous largest teeth (D4, Mx1) (probably also in “K.” boyacensis, C.D.B.C. pers. obs.), posteriorly bifurcated vomer (as M. eulerti), palatines separated in the midline by the pterygoids (unlike B. lucasi and probably K. queenslandicus), slender hyoid bones (unlike K. queenslandicus), 12 cervical vertebrae (as K. queenslandicus and “K.” boyacensis), cervical centra showing ventral foramina (also in L. itilensis), single rib facet in all cervical centra (unlike M. eulerti), rib facets of posterior cervical non divided horizontally (unlike “K.” boyacensis), at least 37 pre-sacral vertebrae (unlike “K.” boyacensis), and zygapophyses present in posterior dorsal vertebrae (unlike K. queenslandicus).]. Its type specimen is MP111209-1, a skeleton (a nearly complete skeleton, lacking the distal part of the right fins), and it is a 3D body fossil. Its type locality is Vereda Arrayan, which is in a Barremian/Aptian marine claystone in the Paja Formation of Colombia.
