Saurocetes

Saurocetes is an extinct genus of probable iniid river dolphins from South America. Two species have been described, Saurocetes argentinus and Saurocetes gigas. The remains are fragmentary, consisting of isolated teeth, rostral fragments and mandibular fragments, which is one reason the genus has an unstable classification: it was noted as far back as 1926 that its placement is uncertain even at the level of the family. It is typically regarded as a member of the Iniidae, the family that has one living genus, Inia, but it has also been suggested that Saurocetes is a synonym of the possible platanistid Ischyrorhynchus, since several specimens referred to that genus closely resemble it.
