Considerable morphological variations are found in the middle ear among mammals. Here I present a three-dimensional atlas of the middle ear ossicles of eulipotyphlan mammals. This group has radiated into various environments as terrestrial, aquatic, and subterranean habitats independently in multiple lineages. Therefore, eulipotyphlans are an ideal group to explore the form-function relationship of the middle ear ossicles. This comparative atlas of hedgehogs, true shrews, water shrews, mole shrews, true moles, and shrew moles encourages future studies of the middle ear morphology of this diverse group.

This project presents a µCT dataset and an associated 3D surface model of the holotype of Donrussellia magna (UM PAT 17; Primates, Adapiformes). UM PAT17 is the only known specimen for the species and consists of a well-preserved left lower jaw with p4-m3. It documents one of the oldest European primates, eventually dated near the Paleocene Eocene Thermal Maximum.

This contribution contains the 3D digital models of some fossil specimens of Wamradolops telloi Stutz and Pozodolops manuelorum Stutz (Metatheria: Polydolopimorphia), from several Palaeogene locations of Peruvian Amazonia. These taxa were described and analyzed in detail in the following publication: Stutz et al. (2026), Hidden diversity of Palaeogene metatherians: a new family of polydolopimorphian marsupials from Peruvian Amazonia. Zoological Journal of the Linnean Society. https://doi.org/10.1093/zoolinnean/zlag006.

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.

In this contribution, we describe the external and internal morphology of a delphinid petrosal bone collected from Ahu Tahai, a burial site located on the Southwestern coast of Easter Island, at Hangaroa. We discuss the taxonomic attribution of this archaeological item and describe its internal structures based on µCT data, including the bony labyrinth and the nerve and vein patterns. Identification of the nerves exists lead us to relocate the identification of the foramen singulare in delphinid petrosals.
