Anderson,
I want to add another point the others have not yet mentioned.
One very simple explanation could be that you are seeing parallax effects,
although it is hard to be sure without knowing which group represents which
magnification or where the points are on the skull. At a minimum, the
Dear Dean and Sonja,

Anderson,
I don’t think you appreciated the importance of the Murat’s comments on your
earlier post on this same topic.
In theory, there is no problem combining objects digitized at different
magnifications, or even digitized by different researchers. However, before
doing so one must
Dear Anderson Feijo,
I assume that the difference is not a matter of scaling (that could be
addressed with the Procrustes superimposition), but one of optical distortions
caused by the lens.
This paper exemplifies this for different lenses:
