Here is a list of websites with open 3D data (or open with membership). This is probably not entirely comprehensive and focuses on sites with data related paleoanthropology/archaeology/neuroscience/anatomy.
- MorphoSource: "a project-based data archive that allows researchers to store and organize, share, and distribute their own 3d data. Furthermore any registered user can immediately search for and download 3d morphological data sets that have been made accessible through the consent of data authors." -- contains Homo naledi data and many many primates
- NESPOS: "The NESPOS online repository includes high resolution 3D Scans of Pleistocene human fossils. We also offer a score of modern reference specimen." -- You need to be a member to access many of the scans.
- EVAN society archive: "The EVAN ARCHIVE is a platform to share digital data from specimens. It was created for researchers who work with 3D volume and surface data of skulls and faces, but also post-cranial elements. The collection mostly comprises Computed Tomography (CT) scans and surface scans of primates and some other mammals. There are also some fossil specimens available." -- They use NESPOS to host the data, you need to be a member to access their data.
- Digital Archive of fossil hominoids: you can purchase the CT scans of several fossil hominoids.
- ORSA: "The Open Research Scan Archive contains high resolution (sub-millimeter) scans of human and non-human crania from the Penn University Museum and other institutions."
- AfricanFossils.org: "The digital collection of animals, human ancestors, as well as ancient stone tools offers a unique tool for scholars and enthusiasts to explore and interact with the collection online. It also provides an opportunity to download models for 3-D printing." -- hominin skulls, stone tools etc. to print
- Digital Morphology Museum, KUPRI: "The Digital Morphology Museum (DMM) provides an environment in which you can readily examine skeletal anatomy using the Primate Research Institute’s (PRI) collection of CT and MRI tomography scans. The goal of this site is to enable you to view the scans of non-human primates and mammals and to download scan data from our database for your original research. It is our great pleasure if you can make use of these data and we hope that they will provide new insights into primate and mammalian evolution." -- Primates
- MPI-EVA Human Evolution Microtomographic Archive: "This archive contains tomographic scans (as well as various types of associated digital data) of fossils from the site of Kromdraai B, South Africa that are curated at the Ditsong National Museum of Natural History."
- MorphoMuseuM: "MorphoMuseuM, also referred to as M3, is a peer reviewed, online journal that aims at enhancing accessibility to 3D models (surface, CT, MRI) of vertebrates, including models of type specimens, anatomy atlases, reconstruction of deformed or damaged specimens, and 3D datasets"
- PaleoView3D: "Paleoview3D is an interactive 3D image library of fossil specimens. Point data for these images were acquired with a laser scanner and then converted into surface models. The results are high resolution images that can be viewed in 3D, magnified and rotated. Additionally, each image can also be downloaded as a data file so that detailed 3D measurements can be made. This database focuses on North American late Paleocene and early Eocene mammals, though check back later for further expansion (both taxonomically and temporally!)"
- Primate Collection of the RMCA: "Download the 3D model of the skull and mandible of the type specimen of Pan paniscus"
- Sketchfab: A site to host and view 3D models. Many are downloadable, but not all. Many museums use it to show 3D models of their artifacts.
- Thingiverse: A place for 3D printable models. Mostly for the 3D printing community in general but there are some cool related models on there.
- https://sketchfab.com/mzechini/models: Sketchfab page of downloadable anatomical models from the University of West Florida
