Speothos pacivorus is an extinct South American canid (Canidae: Cerdocyonina) from the Pleistocene of Lagoa Santa Karst, Central Brazil. This taxon is one of the hypercarnivore canids that vanished from the continent at the end of Pleistocene. Although all remains of Speothos pacivorus were collected in the 19th century by the Danish naturalist Peter W. Lund, few studies have committed to an in-depth analysis of the taxon and the known specimens. Here, we analyzed all biological remains of S. pacivorus hosted in the Peter Lund/Quaternary Collection at the Natural History Museum of Denmark, Copenhagen, by listing and illustrating all its specimens known to date. We also conducted a reconstruction of the holotype, an almost complete cranium, based on a µCT scan, producing an undeformed and crack-free three-dimensional model. With this data available we aim to foster new research on this elusive species.

Macroevolution is integral to understanding the patterns of the diversification of life. As the life sciences increasingly use big data approaches, large multivariate datasets are required to test fundamental macroevolutionary hypotheses. In vertebrate evolution, large datasets have been created to quantify morphological variation, largely focusing on particular areas of the skeleton. We provide a landmarking protocol to quantify morphological variation in skeletal elements across the head, trunk, hindlimb and forelimb using 3-dimensional landmarks and semilandmarks, and present a large pan-skeletal database of bird morphology for 149 taxa across avian phylogeny using CT scan data. This large collection of 3D models and geometric morphometric data is open access and can be used in the future for new research, teaching and outreach. The 3D models and CT scans of the 149 specimens related to this project can be downloaded at MorphoSource (https://www.morphosource.org/projects/00000C420)

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.

We provide a 3D reconstruction of the skull of Latimeria chalumnae that can be easily accessed and visualized for a better understanding of its cranial anatomy. Different skeletal elements are saved as separate PLY files that can be combined to visualize the entire skull or isolated to virtually dissect the skull. We included some guidelines for a fast and easy visualization of the 3D skull.

In this work, we digitally restore the snout of the raoellide Khirtharia inflata from the Kalakot area (Rajouri District, Jammu & Kashmir, India). Raoellids are small, semiaquatic ungulates closely related to cetaceans. The specimen is fairly complete and preserves left and right maxillaries, left premaxillary, and part of the anterior and jugal dentition. The digital restoration of this quite complete but deformed specimen of Khirtharia inflata is a welcome addition to the data available for raoellids and will be used to further the understanding of the origins of cetaceans.

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 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.

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.
