Attockicetus is an extinct genus of remingtonocetid early whale known from the Middle Eocene (Lutetian) Kuldana Formation in the Kala Chitta Hills, in the Attock District of Punjab, Pakistan. Attockicetus is described based on fragmentary cranial material. Their specimen includes a fragmentary rostrum, an endocast (interior of cranium), and an ectotympanic (ear bone). The specimen also had preserved cheek teeth, P3-M3, which is rare in remingtonocetids. Attockicetus is primitive in the retention of large protocones on the upper molars and the location of the orbits anteriorly on the skull. It is probably the most plesiomorphic remingtonocetid
