Figure 2.6. Template for PCA measurements, superimposed upon
left MT III of Tyrannosaurus rex (LACM 7244123844). Landmarks
are shown on the left diagram (a), and linear distances between
landmarks are numbered on the right diagram (b). The numbered
measurements for PCA (b) are as follows:
1. LTOTAL a to b.
2. WPROX d to e
3. W75%TU-DE h to i
4. WSO%TU-DE I to m
5. W25%TU-DE p to q
6. WlST ttou
7. HGINGL b to c
This is measured down the central axis
of the metatarsal, and is not
necessarily its greatest overall
length.
Width of the most proximal surface of
the metatarsal.
Width 75% of the distance from width t-u
to width d-e.
Width 50% of the distance from width t-u
to width d-e,
Width 25% of the distance from width t-u
to width d-e.
Greatest distal width.
Height of ginglymus as measured in
anterior view.
