This contribution contains 3D models of left and right house mouse (Mus musculus domesticus) inner ears analyzed in Renaud et al. (2024). The studied mice belong to four groups: wild-trapped mice, wild-derived lab offspring, a typical laboratory strain (Swiss) and hybrids between wild-derived and Swiss mice. They have been analyzed to assess the impact of mobility reduction on inner ear morphology, including patterns of divergence, levels of inter-individual variance (disparity) and intra-individual variance (fluctuating asymmetry)

The holotype of Hamadasuchus rebouli Buffetaut 1994 from the Kem Kem beds of Morocco (Late Albian – Cenomanian) consists of a left dentary which is limited, fragmentary and reconstructed in some areas. To aid in assessing if the original diagnosis can be considered as valid, the specimen was CT scanned for the first time. This is especially important to resolve the taxonomic status of certain specimens that have been assigned to Hamadasuchus rebouli since then. The reconstructed structures in this contribution are in agreement with the original description, notably in terms of alveolar count; thus the original diagnosis of this taxon remains valid and some specimens are not referable to H. rebouli anymore.

The present 3D dataset contains 3D models of the endocranial cast of the raoellid Khirtharia inflata retrieved from the middle Eocene of the Upper Subathu Formation in the Kalakot area (India). Raoellidae are closely related to stem cetaceans and bring crucial information to understand the earliest phase of land to water transition in Cetacea.

Current knowledge on the skeletogenesis of Chondrichthyes is scarce compared with their extant sister group, the bony fishes. Most of the previously described developmental tables in Chondrichthyes have focused on embryonic external morphology only. Due to its small body size and relative simplicity to raise eggs in laboratory conditions, the small-spotted catshark Scyliorhinus canicula has emerged as a reference species to describe developmental mechanisms in the Chondrichthyes lineage. Here we investigate the dynamic of mineralization in a set of six embryonic specimens using X-ray microtomography and describe the developing units of both the dermal skeleton (teeth and dermal scales) and endoskeleton (vertebral axis). This preliminary data on skeletogenesis in the catshark sets the first bases to a more complete investigation of the skeletal developmental in Chondrichthyes. It should provide comparison points with data known in osteichthyans and could thus be used in the broader context of gnathostome skeletal evolution.

M3#175 NMMNH P-66225 is from upper lower Smithian to lower upper Smithian beds (Thaynes Group). The collecting site is located about 2.75 km south-southeast of the Winecup Ranch, east-central Elko County, Nevada, USA. P-66225 is a partial skull preserved within a large limestone nodule, with its right side exposed. It preserves the portion between the cleithrum posteriorly, and the level of the hind margin of the orbital opening anteriorly. The fossil has a length of 26 cm.
