3D objects viewable in-browser can be found here: https://sketchfab.com/FloridaMuseum/models
So far about 800 objects have been uploaded, including within the past fortnight.
Some noninteractive colour images are available here: https://www.floridamuseum.ufl.edu/overt/gallery/
The Sketchfab collection seems to have been set to non-downloadable. The morphsource collection can be downloaded, but only as an image sequence, not as 3D meshes. Fairly easy to convert images sequence to mesh, but I wish they had made the task more straightforward.
I take it back. The volumetric image series format of morphsource is not agreeable to being easily converted to mesh objects.
There are meshes in morphosource too. Didn't try downloading any but they are available as STL files with 1-2 million polygons per model. Some meshes are individual bones or skulls, others are complete specimens. The interface is a bit clumsy but you can use "mesh" in your search string
Thanks. I will re-look.
They're in a number of places, but the most complete seems to be morphosource:
