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)

Megatherium americanum MNHN.F.PAM276 View specimen

M3#14 This model corresponds to a virtually reconstructed bony labyrinth of the right inner ear of the skull MNHN-F-PAM 276, attributed to the extinct giant ground sloth Megatherium americanum. The fossil comes from Pleistocene deposits at Rio Salado (Prov. Buenos Aires, Argentina). The bony labyrinth of Megatherium shows semicircular canals that are proportionally much larger than in the modern two-toed and three-toed sloths. The cochlea in Megatherium shows 2.5 turns, which is a rather high value within Xenarthra. Overall, the shape of the bony labyrinth of Megatherium resembles more that of extant armadillos than that of its extant sloth relatives. Type: "3D_surfaces" doi: 10.18563/m3.sf14   state:published

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

This project presents the osteological connexions of the petrosal bone of the extant Hippopotamidae Hippopotamus amphibius and Choeropsis liberiensis by a virtual osteological dissection of the ear region. The petrosal, the bulla, the sinuses and the major morphological features surrounding the petrosal bone are labelled, both in situ and in an exploded model presenting disassembly views. The directional underwater hearing mode of Hippopotamidae is discussed based on the new observations.

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.

The present 3D Dataset contains the 3D models of extant Chiropteran endocranial casts, documenting 16 of the 19 extant bat families. They are used by Maugoust & Orliac (2023) to assess the correspondences between the brain and brain-surrounding tissues (i.e., neural tissues, blood vessels, meninges) and their imprint on the braincase, allowing for eventually proposing a Chiroptera-scale nomenclature of the endocast.

Allosaurus jimmadseni UMNH VP C481 View specimen

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.
