RE: Assistance with anatomical descriptions of dimensions!

Dealing with this myself when attempting to translate some Russian texts 
(before finding them already translated by others, using the Polyglot 
Paleontologist; here: http://www.paleoglot.org/index.cfm) I found a difficult 
time to determine the dimensions without already using a ruler and the figures 
and doing it myself.

In the cases you make, the author has used some conventions: In teeth, "wide" 
and "breadth" were often simply the perpendicular to the length in the same 
view. Because of this, three measures would be "length, width, and thickness," 
but we would call this "apicobasal length, mesiodistal length, and linguolabial 
length." The first might also be termed height, and the third "width," using 
the long axis of the associated jaw as the a "length" baseline determinate.

Authors often find a "base orientation" from which to measure their specimens, 
and seldom report what this measurement is. When one finds such a case, 
consider matching the given measurment while rotating the aspect of the element 
until it matches. I am simply unfamiliar with the method regarding bony plates, 
so this is the best I can offer.
