Figure 4.3. Surface reconstructions of the humerus, radius, and ulna of Plesiadapis<br />

cookei (UM 87990) using CT data (CT image resolution = 0.18(x) x 0.18(y) x 0.20(z)<br />

mm). A, the three bones are shown in anterior, lateral, and proximal views, and<br />

articulated so that respective joint surfaces are maximally overlapping. Note that the<br />

forearm is flexed and projects laterally relative to the proximodistal and anteroposterior<br />

axes of the proximal end of the humerus, respectively. B, proximal view of humerus.<br />

Note that the axis of the distal end is rotated 32° lateral to the axis of the proximal end,<br />

explaining the lateral projection of the radius and ulna.<br />
