 The genus synonymy was rejected by later authors, though similarities between the genera and the discovery of distinctly halisaurine vertebrae in Niger allowed the genus to be firmly placed within the Halisaurinae.Thus, "Pluridens" is today considered a highly derived halisaurine.The type specimen of "P. walkeri" is BMNH R14153, an almost complete dentary recovered from the Maastrichtian Farin-Doutchi Formation near Mount Ilatarda, Niger.
