3D Morphometric and posture study of felid scapulae using statistical shape modelling

PLoS One. 2012;7(4):e34619. doi: 10.1371/journal.pone.0034619. Epub 2012 Apr 11.

Abstract

We present a three dimensional (3D) morphometric modelling study of the scapulae of Felidae, with a focus on the correlations between forelimb postures and extracted scapular shape variations. Our shape modelling results indicate that the scapular infraspinous fossa becomes larger and relatively broader along the craniocaudal axis in larger felids. We infer that this enlargement of the scapular fossa may be a size-related specialization for postural support of the shoulder joint.
