The present 3D Dataset contains the 3D models of the holotype and only specimen of Kalakocetus aurorae, a new cetacean retrieved from the Kalakot area in northwestern India. This specimen consists in a left hemimandible preserving the root of i3, p2, p4, m1 and m3 in situ. Its primitive morphology, with a tricuspid m3 morphologically intermediate between Raoellidae and Pakicetidae, makes it the first offshoot of Cetacea and provides crucial new elements to understand the setting up of the peculiar dental morphology of early cetaceans.
