So my understanding (which might be wrong) is that (with a few rare exceptions) the paleontological value of fossil bones is entirely a function of their 3D shape (and perhaps a small sample of the material they are made of) and the information about where and in what conditions they are found.
Given that we now have 3D scanners shouldn’t museums and universities be selling off the originals to finance more research? Or am I missing something?
I’d add that the failure to have greater funding for new expeditions means we are constantly losing potential fossils to erosion, looters, damage etc… It’s crazy to think that the optimal overall scientific end is served by selling none of the fossils in institutional collections (even the low value ones) while knowing that there are probably high value fossils being lost because we aren’t finding them before they are damaged or that land is developed or whatever.
Also, one could simply include buy-back, borrowing or sampling clauses in any sale. Thus, at worst, when the museum wants to do later sampling it must buy back or partially compensate the current private owner putting them in a strictly better situation.
