Bone coordinate measurement

[theropod@garnet.berkeley.edu (John R. Hutchinson)]

Anyone that can help:

I need to find a cheap and efficient method to measure (x,y,z) coordinates
of large, unwieldy bones (say, sauropod elements). The most parsimonious
amount of points would be best; an offhand guess would be 100 or so
points/bone. Anyone have any tried-and-true methods?
