This 3D dataset contains the 3D models of the fossil specimens of Lilliputia gujjarorum, a new tiny dichobunoid artiodactyl from the early middle Eocene of northwestern India. The material includes the holotype, GU/RJ/003 (Rajouri Collection, H.N.B. Garhwal University), consisting of an associated left mandible fragment preserving the distal part of p4 and m1–3 (GU/RJ/003a) and a left maxillary fragment preserving P4 and M1–3 (GU/RJ/003b), as well as the referred specimen GU/RJ/005, a right mandible fragment preserving m1–2. The exceptionally small body size of Lilliputia, among the smallest known in Artiodactyla, together with its mosaic of primitive and derived dental characters, provides new insights into the early evolution, palaeobiogeography, and ecological diversification of artiodactyls during the Eocene.

This contribution contains 3D models of upper molar rows of Cypriot mice (Mus cypriacus) and house mice (Mus musculus domesticus) from the island of Cyprus. Although morphologically similar and occasionally syntopic, the two species differ in habitat use and dietary strategies, ranging from anthropogenic resources in M. m. domesticus to a more natural and diversified trophic niche in M. cypriacus. Mandibular and molar shape variation was quantified through 3D geometric morphometrics, enabling the detection of interspecific differences, allometric trends, and age-related dental wear trajectories. The morphometric descriptors were evaluated for their capacity to capture phylogenetic divergence, ecological specialization, and ontogenetic dynamics. Results highlight that subtle morphological signals can expose fine-scale ecological processes and species-specific adaptive strategies.

The present 3D dataset contains the 3D models analyzed in Xing et al. (in press), Newly discovered Cretaceous dinosaur track sites from the Jiaguan Formation, Sichuan Province, China: ichnotaxonomy and preservation. The dataset includes photogrammetric 3D models of the specimens shown in Figures 6–9 and 16–17 of the original article. These correspond to track-bearing slabs and selected footprints from the Hongyangoukou and Jinyuxi tracksites and the Shimiaogou 2025 tracksite in the Gulin area, Sichuan Province, China. The Hongyangoukou material comprises three reddish-brown siltstone slabs preserving at least 61 theropod tracks, including nine trackways (HYGK-T1 to HYGK-T9) and isolated footprints (HYGK-TI1 onward). The Jinyuxi material comprises one isolated theropod natural cast (JYX-TI5) assigned to cf. Eubrontes, associated with microbially induced sedimentary structures (MISS). The Shimiaogou 2025 material comprises two slabs preserving at least 25 dinosaur footprints, including ornithopod trackways SMG25-O1 and SMG25-O2, theropod trackway SMG25-T1, and isolated footprints; all occur as natural positive reliefs. The 3D surface models are provided in PLY format. 

Eubrontes isp. HYGK Slab 1 View specimen

M3#1982 All footprints in Fig. 6 are tridactyl theropod footprints assigned to Morphotype I and tentatively identified as Eubrontes-like. Fig. 6 (Hongyangoukou Slab 1) preserves at least 31 footprints, comprising seven trackways (HYGK-T1–T7) and 15 isolated footprints (HYGK-TI1–TI15). They are preserved as natural molds in reddish-brown siltstone and are heavily weathered, but they generally retain distinct tridactyl outlines and U- or V-shaped metatarsophalangeal regions. Claw impressions are present in some specimens (e.g., T3, T7-L1, and TI9), whereas digital pad impressions are absent. Footprint length ranges from 10.8 to 20.9 cm (mean ≈16.0 cm); the length-to-width ratio ranges from 1.1 to 1.7 (mean ≈1.4); mesaxony is weak (mean ≈0.47); and the divarication angle between digits II and IV ranges from 41° to 73° (mean ≈60°). The stride lengths of T1, T3, T4, and T6 are 144.5, 104.8, 122.3, and 64.5 cm, respectively, corresponding to 9.7, 5.6, 9.4, and 3.3 times their respective mean footprint lengths. T1 and T5 show outward rotations of about 4° and 9°, respectively. T3 is among the best-preserved examples, with digit III the longest and stoutest, digit IV the shortest, and clear claw impressions present on digits II and III, whereas TI10 is a complete tridactyl track. These footprints are therefore small theropod tracks of Morphotype I, tentatively assigned to Eubrontes-like. Type: "3D_surfaces" doi: 10.18563/m3.sf.1982   state:in_press

Eubrontes isp. HYGK Slab 2 View specimen

M3#1983 All footprints in Fig. 7 (Hongyangoukou Slab 2) are tridactyl theropod footprints assigned to Morphotype II and tentatively identified as Eubrontes-like. Slab 2 preserves at least 28 footprints, including two trackways (HYGK-T8 and HYGK-T9) and 18 isolated footprints (HYGK-TI16–TI33). Preservation is poorer than on Slab 1: impressions are shallower and more rounded overall; in T9 and in some isolated footprints (e.g., TI17, TI18, TI20, TI23, TI24, and TI26), discrete digit impressions are not recognizable and instead appear as oval depressions, whereas the remaining footprints show three discernible digit impressions. No digital pad impressions were observed; the metatarsophalangeal region is U-shaped, and relatively clear claw impressions are preserved in some tracks, such as T8-R1, TI18, and TI31. Footprint length ranges from 11.2 to 21.6 cm (mean 15.1 cm); the length-to-width ratio ranges from 0.9 to 1.7 (mean 1.4); mesaxony is weak (mean 0.45); and the divarication angle between digits II and IV ranges from 46° to 62° (mean 54°). The stride lengths of T8 and T9 are 60 cm and 116 cm, corresponding to approximately 4 and 7.7 times the average footprint length, respectively; the pace angulation of T9 is 166°. TI31 is relatively well preserved and markedly symmetrical, with digit III being the stoutest and longest, and with a distinct, sharp claw impression.

Eubrontes isp. HYGK Slab 3 View specimen

M3#1984 All footprints in Fig. 8 (Hongyangoukou Slab 3) are tridactyl theropod footprints assigned to Morphotype I and tentatively identified as Eubrontes-like. Slab 3 preserves at least seven isolated footprints (HYGK-TI34–TI40) and no trackways; these footprints have relatively distinct tridactyl outlines and U- or V-shaped metatarsophalangeal regions, with some specimens (e.g., TI37 and TI38) preserving claw impressions but lacking digital pad impressions. The divarication angle between digits II and IV on Slab 3 ranges from 53° to 57° (mean 56°). As members of Morphotype I, they fall within the morphotype ranges for footprint length (10.8–20.9 cm; mean 16.0 cm), length-to-width ratio (1.1–1.7; mean 1.4), and mesaxony (weak; mean 0.47).

Eubrontes isp. JYX-TI5 View specimen

M3#1985 JYX-TI5 is tentatively assigned to cf. Eubrontes. It is preserved as a natural cast on dark red quartz sandstone, with a preservation grade of 0.5–1.5. It shows largely complete digit impressions and a metatarsophalangeal region, as well as some claw impressions, but no digital pad impressions. The footprint has three distinct digit impressions, a relatively distinct U-shaped metatarsophalangeal region, a separation between the proximal region of digit III and the metatarsophalangeal region, and relatively clear claw impressions; its surface bears irregular linear ridges that likely represent microbially induced sedimentary structures (MISS). JYX-TI5 is 22.1 cm long, with a length-to-width ratio of 1.5, weak mesaxony (0.45), and a divarication angle between digits II and IV of 50°; the interdigital angle between digits II and III is slightly larger than that between digits III and IV.

Grallator isp. SMG25 Slab 1 View specimen

M3#1986 Fig. 16 includes ornithopod footprints assigned to Caririchnium isp. and theropod footprints tentatively assigned to cf. Grallator. The ornithopod tracks are natural casts, clearest on Slab 1, and show a distinct quadripartite structure. Preservation grade is 1–2; footprint length is 23.5–31.2 cm (mean 27.3 cm), and length-to-width ratio is 1.2–1.5 (mean 1.4). They are highly symmetrical, with three clear rounded digit impressions and a sub-circular metatarsophalangeal region separated by a depression; claw impressions are absent, mesaxony is weak (0.24–0.38; mean 0.30), and the mean divarication angle between digits II and IV is 49°. The potential trackway SMG25-O2 has a pace length about 2.7 times the footprint length, a pace angulation of 111°, and inward rotation of about 15°. The theropod tracks are mostly isolated, with only one potential trackway, SMG25-T1, on Slab 1. Preservation grade is 1–2; footprints are small (8.5–20.4 cm) and generally slender, mostly complete tridactyl impressions with digit III longest and digit II shortest, V-shaped metatarsophalangeal regions, and faint claw impressions or digital pads in some tracks. SMG25-T1 comprises two footprints (mean length 19.9 cm, length-to-width ratio 1.9, mesaxony 0.54, mean divarication angle between digits II and IV 41°). Isolated footprint TI9 is the best preserved (length 9.8 cm, length-to-width ratio 2.1, mesaxony 0.72, divarication angle between digits II and IV 38°), with the metatarsophalangeal pad of digit IV aligned along the axis of digit III.

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 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.

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)
