Scientists CT-scanned thousands of natural history specimens, which you can access for free
Natural history museums have entered a new stage of scientific discovery and accessibility with the completion of open Vertebrate (oVert), a five-year collaborative project among 18 institutions to create 3D reconstructions of vertebrate specimens and make them freely available online.
The project is led by the
@FloridaMuseum of Natural History and includes several biologists from the University of Michigan. A paper summarizing the project and its impacts was published online March 6 in the journal BioScience.
Natural history museums got their start in the 16th century as cabinets of curiosity, in which a few wealthy individuals amassed rare and exotic specimens, which they kept mostly to themselves. Since then, museums have become a resource for the public, with exhibits that showcase biodiversity for anyone interested in learning about it.
However, most natural history collections remain behind closed doors, accessible only to scientists who must either travel to see them or ask that a small number of specimens be mailed on loan. The research team behind oVert wants to change that.
“If you require someone to get on a plane and travel to you to collaborate, that’s prohibitive in a lot of ways,” said David Blackburn, principal investigator of the oVert project and curator of herpetology at the Florida Museum of Natural History. “Now we have scientists, teachers, students and artists around the world using these data remotely.”
Between 2017 and 2023, oVert project members took CT scans of more than 13,000 specimens, with representative species across the vertebrate tree of life. This includes more than half the genera of all amphibians, reptiles, fish and mammals.
More than 1,600 specimens from
@umichLSA's Museum of Zoology collections were scanned as part of the
#oVertTCN project—mostly mammals, reptiles, amphibians and fish, along with a few birds. The museum also scanned several hundred specimens for partner institutions.
“The University of Michigan Museum of Zoology is the home to some of the largest collections of vertebrates in the world. We were able to utilize those collections and our own in-house CT scanner to produce 3D models of thousands of our voucher specimens, as well as material from collaborating collections,” said Cody Thompson (@codythompson51), mammal collections manager and associate research scientist at
#UMMZ.

This specimen was collected in 1929 in the Philippines and scanned at the University of Michigan Museum of Zoology CT as part of the open Vertebrate (oVert) project, a five-year collaborative effort among 18 institutions to create 3D reconstructions of vertebrate specimens and to make them freely available online.

ALT CT scan render of a brown-throated wren from Central America. This specimen was collected in 1962 in Costa Rica and scanned at the University of Michigan Museum of Zoology CT as part of the open Vertebrate (oVert) project, a five-year collaborative effort among 18 institutions to create 3D reconstructions of vertebrate specimens and to make them freely available online.

ALT CT scan render of an Eastern Massasauga Rattlesnake, which is found across much of the central United States and parts of Canada. This specimen was collected in Washtenaw County, Michigan, in 1904 and scanned at the University of Michigan Museum of Zoology CT as part of the open Vertebrate (oVert) project, a five-year collaborative effort among 18 institutions to create 3D reconstructions of vertebrate specimens and to make them freely available online.

ALT CT scan render of a southern three-banded armadillo, which can be found in South America. This specimen was collected in Paraguay in 1977 and was scanned at the University of Michigan Museum of Zoology CT as part of the open Vertebrate (oVert) project, a five-year collaborative effort among 18 institutions to create 3D reconstructions of vertebrate specimens and to make them freely available online.
