Veterinary education often relies on cadaveric specimens, but there is increasing demand for alternatives due to limited resources and ethical considerations. To address this, we developed a 3D printed ‘explodable’ model of a dog cranium with detachable, magnetized cranial components      for teaching anatomy to students. This model was generated from a computed tomographic scan of a juvenile dog cranium for which cranial sutures were still partially open and segmented such that major cranial bones were isolated. All bones are printed at actual size and retain openings for cranial nerves and major vessels. This interactive model enhances anatomical education by supplying a hands-on tool that can be used either in the classroom setting or for independent learning and can be incorporated at the high school, college, or veterinary school level. It is currently being integrated into the first-year anatomy foundation course at Cornell University’s College of Veterinary Medicine. The model can be printed using any hobbyist or specialist 3D printer and we outline assembly instructions on how to attach magnets at prefabricated attachment points.      Using both digital and 3D printed resources, we hope to help to address current shortages of anatomical resources and      also      inspire future generations of practicing veterinarians by making anatomy more accessible and engaging.

The present 3D dataset contains the 3D models of two fossil seeds of Vitaceae from the Quercy fossiliferous area, southwestern France. One seed comes from the Eocene locality of Fontoffre 2, and the other from the Oligocene locality of Baraval. These seeds document new fossil species within the Vitaceae family and illustrate the morphological diversity of this family during the Palaeogene. The CT scan data were processed with ImageJ and Mimics Innovation Suite version 1.13 to reconstruct the specimens. Here we provide .stl files that can be easily opened with the software MeshLab.

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.

This contribution presents the three-dimensional digital models (i.e., skull, endocast, and inner ear) of a uniquely well-preserved and nearly complete skull (MCL 4228) attributed to the Late Pleistocene giant mylodontid ground sloth Ocnotherium giganteum, discovered in the Toca dos Ossos cave (Bahia State, Brazil). This specimen was described and figured in the following publication: Pujos et al. 2026: The neotropical giant ground sloth Ocnotherium giganteum (Xenarthra, Mylodontinae) from the Late Pleistocene of Brazil: anatomy, paleoneurology, and phylogenetic relationships. Zoological Journal of the Linnean Society. https://doi.org/10.1093/zoolinnean/zlag008

The democratization of 3D techniques in recent years provides exciting new opportunities for the study of complex fossils. In the present contribution, we provide a virtual reconstruction of a partial, disarticulated metriorhynchid (Metriorhynchidae, Thalattosuchia, Crocodylomorpha) skull from the Late Jurassic of northwestern Switzerland. This virtual reconstruction was used to produce high quality scientific illustrations of the whole skull for descriptive purposes. The reconstructed skull also served for the estimation of the total body length of the specimen and to propose a life reconstruction of the animal in its paleoenvironment. In an effort for transparency, we review the sources that were consulted for the life reconstruction and explain the choices that we had to make.

The present 3D Dataset contains the 3D models of two endocarps from the Oligocene of Baraval Quercy locality. These endocarps document new fossil genera within the Anacardiaceae family and illustrate the morphological diversity of this family during the Palaeogene. The CT-scan data were processed with ImageJ and Mimics Innovation Suite version 1.13 to reconstruct the specimens. Here we provide .stl files easy to read with the software Meshlab.
