I read Christy's question a little differently, and requiring some clarification. First, Dean, doesn't Dean & Felice fix the angle between jaw and cranium so that you can subject a craniomandibular dataset to a common GPA, which at the PLS step has the benefit of preserving relative size relations

Christy, That data example contained variation in relative jaw position among specimens, which could affect shape estimates, as well as down-stream shape analyses. Several approaches have been proposed for dealing with such rotational variation (see Adams 1999; also Bookstein’s Orange book). O
