Dalanistes ahmedi

Dalanistes is an extinct genus of remingtonocetid early whale known from the late-early Eocene (Lutetian, ) of Kutch, India and Punjab and Balochistan, Pakistan. Dalanistes is closely related to Remingtonocetus (the type genus of Remingtonocetidae, a slightly more derived family of early whales), but also shares several features with Ambulocetus (the type of Ambulocetidae, earlier more primitive whales), and, with its combination of terrestrial and amphibious adaptations, Dalanistes apparently is an intermediate form between these two groups. Isotopic evidence suggest that Dalanistes had a marine diet. left|thumb|Life restoration Dalanistes is known from several localities and collections. The holotype is a skull and a postcranial skeleton. Additional fossils referred to Dalanistes include crania, several vertebrae and sacra, possible caudals, one side of the pelvis, and a distal femur. The alveoli is all that is left of the dentition, but the dental formula apparently was .

The vertebral elements of the sacrum are solidly fused and form a well-developed articular surface for the pelvis. The ilium is robust and long, and has a large acetabulum similar to that in Remingtonocetus. The femur had a spherical head, a medial condyle considerably larger than the lateral, and a shallow patellar groove. Taken together this morphology suggests the presence of well-developed hind limbs.
