This 3D dataset contains the 3D models of the fossil specimens of Lilliputia gujjarorum, a new tiny dichobunoid artiodactyl from the early middle Eocene of northwestern India. The material includes the holotype, GU/RJ/003 (Rajouri Collection, H.N.B. Garhwal University), consisting of an associated left mandible fragment preserving the distal part of p4 and m1–3 (GU/RJ/003a) and a left maxillary fragment preserving P4 and M1–3 (GU/RJ/003b), as well as the referred specimen GU/RJ/005, a right mandible fragment preserving m1–2. The exceptionally small body size of Lilliputia, among the smallest known in Artiodactyla, together with its mosaic of primitive and derived dental characters, provides new insights into the early evolution, palaeobiogeography, and ecological diversification of artiodactyls during the Eocene.

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.

The present 3D dataset contains 3D models of new material from the middle Eocene of the Upper Subathu Formation in the Kalakot area (India), documenting the anterior dentition of the raoellid Indohyus indirae. Raoellidae are closely related to stem cetaceans and bring crucial information to understand the earliest phase of land to water transition in Cetacea.

In this work, we digitally restore the snout of the raoellide Khirtharia inflata from the Kalakot area (Rajouri District, Jammu & Kashmir, India). Raoellids are small, semiaquatic ungulates closely related to cetaceans. The specimen is fairly complete and preserves left and right maxillaries, left premaxillary, and part of the anterior and jugal dentition. The digital restoration of this quite complete but deformed specimen of Khirtharia inflata is a welcome addition to the data available for raoellids and will be used to further the understanding of the origins of cetaceans.
