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.

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.

This contribution contains the 3D model of an endocranial cast analyzed in “A 10 ka intentionally deformed human skull from Northeast Asia”. There are many studies on the morphological characteristics of intentional cranial deformation (ICD), but few related 3D models were published. Here, we present the surface model of an intentionally deformed 10 ka human cranium for further research on ICD practice. The 3D model of the endocranial cast of this ICD cranium was discovered near Harbin City, Province Heilongjiang, Northeast China. The fossil preserved only the frontal, parietal, and occipital bones. To complete the endocast model of the specimen, we printed a 3D model and used modeling clay to reconstruct the missing part based on the general form of the modern human endocast morphology.
  

Homo sapiens IVPP-PA1616 View specimen

	M3#972 The frontal region of the endocast is flattened, probably formed by the constant pressure on the frontal bone during growth. There is a well-developed frontal crest on the endocranial surface. The endocast widens posteriorly from the frontal lobe. The widest point of the endocast is at the lateral border of the parietal lobe. The lower parietal areas display a marked lateral expansion. The overall shape of the endocast is asymmetrical, with the left side of the parietal lobe being more laterally expanded than the right side. Like the frontal lobe, the occipital lobe is also anteroposteriorly flattened. Type: "3D_surfaces" doi: 10.18563/m3.sf.972   state:published	Download 3D surface file

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 analyzed in Bianucci et al. 2023, A heavyweight early whale pushes the boundaries of vertebrate morphology, Nature. These include bones of the holotype of new species Perucetus colossus (MUSM 3248), as well as the articulated skeleton of Cynthiacetus peruvianus (holotype, MNHN.F.PRU10). The latter was used to estimate the total skeleton volume of P. colossus.

The study of titanosaur paleobiology has been severely hampered by the incomplete nature of their fossil record, particularly the scarcity of well-preserved and relatively complete cranial remains. Even the most complete titanosaur skulls are often fractured, incomplete, or deformed, which has resulted in a limited knowledge of the paleobiology related to cranial anatomy, especially functional morphology. In this context, we present the digital restoration of the skull of the Argentinean titanosaur Sarmientosaurus musacchioi, created using the open-source 3D modeling software Blender. The digitally restored model is freely accessible to other researchers, facilitating broader research and comparative studies.
