Hi Mike,
I agree with Yukun about CT. I can't think of a better way than
digitization. Except from the 3D models if the raw acquisition data is
also archived then fossil information can be accessible to all levels of
accuracy to everyone. If the scanning is performed with a scale (i.e. a
calcite crystal for forams) then information of fossil's integrity
becomes available too. I also found out that once segmentation has been
performed it can be exported to 3D ascii files and can be archived
together with the raw acquisition data to be recombined by the user, if
needed. I send here a link and attachment to a recent paper where I show
all these:
