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).

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 15 specimens selected from the 69 3D models analyzed in the paper “3D topography as an indicator of change in food processing ability in the conodont genus Palmatolepis elements”. 3D topographic analysis of Palmatolepis P1 conodont elements from the Late Devonian period revealed an increase in blade sharpness together with a reduction in platform size. This indicates morphofunctional adaptation to more efficient prey processing.

This contribution contains the 3D models described and figured in the following publication:Skull and Inner Ear Morphometrics in Sheep and Goats: Species and Breed Differentiation with Bioarchaeological Applications (Hemelsdael et al. submitted). The models include the external surface of a complete skull and inner ear of both a sheep (Ovis aries) and a goat (Capra hircus), generated from micro-CT scans. In the associated paper, we used 3D geometric morphometric data to assess inter and intra (i.e. between breeds) discrimination based on complete skulls, skull fragments and the semi-circular canals of the inner ear.

M3#902 The material consists of a 3D reconstruction of the counterpart of a 30 cm2 patch of skin impression associated with the anterior dorsal ribs/pectoral region of the specimen of Allosaurus jimmadseni UMNH VP C481. The skin shows a semi-uniform basement of 1-2 mm diameter pebbles with a smaller number of slightly larger (up to 3 mm) ovoid scales. The irregular shape, distribution, and overall small size of these larger scales suggest that they are not classifiable as feature scales but rather as variations in the basement scales.

In this contribution a third new species of the rare genus Burmesescorpiops Lourenço, 2016 is described. The discovery of this new element belonging to the family Palaeoeuscorpiidae Lourenço, 2003 and to the subfamily Archaeoscorpiopinae Lourenço, 2015 brings further elements to support the validity of the genus Burmesescorpiops. This generic group remains however, poorly speciose. This is the latest discovery of Burmesescorpiops wunpawng, the name is derived from the Kachin Hilltribe peoples who are indigenous to the area. The data provided here is a 3D surface.

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.

This contribution contains the three-dimensional models of the most complete and/or informative fossil materials attributed to Peradectes crocheti Gernelle, 2024, the earliest peradectid metatherian species of Europe, from its type locality (Palette, Provence, ~55 Ma). These specimens were analyzed and discussed in: Gernelle et al. (2024), Taxonomy and evolutionary history of peradectids (Metatheria): new data from the early Eocene of France. https://doi.org/10.1007/s10914-024-09724-5

Turtles are one of the most impressive vertebrates. Much of the body is either hidden in a shell or can be drawn into it. Turtles impress with their individual longevity and their often peaceful disposition. Also, with their resilience, they have survived all extinction events since their emergence in the Late Triassic. Today's diversity of shapes is impressive and ranges from the large and high domed Galapagos turtles to the hamster-sized flat pancake turtles. The holotype of one of the oldest fossil turtles, Proganochelys quenstedtii, is housed in the paleontological collection in Tübingen/Germany. Since its discovery some years before 1873, P. quenstedtii has represented the 'prototype' of the turtle and has had an eventful scientific history. It was found in Neuenhaus (Häfner-Neuhausen in Schönbuch forest), Baden-Württemberg, Germany, and stems from Löwenstein-Formation (Weißer Keupersandstein), Late Triassic. The current catalogue number is GPIT-PV-30000. The specimen is listed in the historical inventory “Tübinger Petrefaktenverzeichnis 1841 bis 1896, [folio 326v.]“, as “[catalogue number: PV]16549, Schildkröte Weiser Keupersandstein Hafnerhausen” [turtle from White Keuper Sandstone]. Another, more recent synonym is “GPIT/RE/9396”. The same specimen was presented as uncatalogued by Gaffney (1990). Here we provide a surface scan of the steinkern for easier access of this famous specimen to the scientific community.

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.
