==Discovery and naming== The first specimen was collected by who described it as mandibular fragments of Protocetus sloani. described two new species, Andrewsiphius kutchensis and A. minor based on their previous material and new mandibular fragments. Later researchers interpreted the same mandibular specimens as belonging to Remintonocetus. reinterpreted these specimens as fragments from maxillae, and determined that the described "confluence of the mandibular canals anteriorly" was in fact the narial passages. Gingerich et al. also determined that the variations in size among proposed species were within the normal variation for a single species and therefore attributed a number of referred specimens as belonging to Andrewsiphius sloani.
