About this 3D model

[doi:10.1371/journal.pone.0069265.s002](http://dx.doi.org/10.1371/journal.pone.0069265.s002) Multimedia S1. ZMNH M8137. A 3D model of ZMNH M8137 is included to demonstrate the scans for each psittacosaur specimen. ZMNH M8137 plotted closest to the consensus shape in each PC plot and likely represents a reasonably undistorted Lujiatun psittacosaur form.
