This contribution provides the raw files for the μCT-scan data and renderings of the three-dimensional digital models of two fossil teeth of a geomyin geomorph rodent (Caribeomys merzeraudi), discovered from lower Oligocene deposits of Puerto Rico, San Sebastian Formation (locality LACM Loc. 8060). These fossils were described, figured and discussed in the following publication: Marivaux et al. (2021), An unpredicted ancient colonization of the West Indies by North American rodents: dental evidence of a geomorph from the early Oligocene of Puerto Rico. Papers in Palaeontology. https://doi.org/10.1002/spp2.1388

	M3#712 Right lower dp4: isolated deciduous premolar. The specimen was scanned with a resolution of 5 µm using a μ-CT-scanning station EasyTom 150 / Rx Solutions (Montpellier RIO Imaging, ISE-M, Montpellier, France). AVIZO 7.1 (Visualization Sciences Group) software was used for visualization, segmentation, and 3D rendering. This isolated tooth was prepared within a “labelfield” module of AVIZO, using the segmentation threshold selection tool.

The holotype of Hamadasuchus rebouli Buffetaut 1994 from the Kem Kem beds of Morocco (Late Albian – Cenomanian) consists of a left dentary which is limited, fragmentary and reconstructed in some areas. To aid in assessing if the original diagnosis can be considered as valid, the specimen was CT scanned for the first time. This is especially important to resolve the taxonomic status of certain specimens that have been assigned to Hamadasuchus rebouli since then. The reconstructed structures in this contribution are in agreement with the original description, notably in terms of alveolar count; thus the original diagnosis of this taxon remains valid and some specimens are not referable to H. rebouli anymore.

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.

The present 3D Dataset contains the 3D model analyzed in the publication : On Roth’s “human fossil” from Baradero, Buenos Aires Province, Argentina: morphological and genetic analysis. The “human fossil” from Baradero, Buenos Aires Province, Argentina, is a collection of skeleton parts first recovered by Swiss paleontologist Santiago Roth and further studied by anthropologist Rudolf Martin. By the end of the 19th century and beginning of the 20th century it was considered as one of the oldest human skeletons from the southern cone. We studied the cranial anatomy and contextualized the ancient individual remains. We discuss the context of the finding, conducted an osteobiographical assessment and performed a 3D virtual reconstruction of the skull, using micro-CT-scans on selected skull fragments and the mandible. This was followed by the extraction of bone tissue and teeth samples for radiocarbon and genetic analyses, which brought only limited results due to poor preservation and possible contamination. We estimate that the individual from Baradero is a middle-aged adult male. We conclude that the revision of foundational collections with current methodological tools brings new insights and clarifies long held assumptions on the significance of samples that were recovered when archaeology was not yet professionalized.

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 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.
