File:Toroceratops analysis.png
Summary
Principal Component Analysis and linear regression between shape and size performed on skulls.
A, morphological changes in skull shape associated with size. Points dimensions are proportional to specimen Centroid Size. The continuous line represents Torosaurus latus morphospace. The dotted line represents Triceratops prorsus morphospace, and the dashed line represents Triceratops horridus morphospace.
Principal Component Analysis and linear regression between shape and size performed on squamosals.
B, morphological changes in squamosal shape associated with size. Points dimensions are proportional to specimen Centroid Size. An asterisk indicates specimens with dubious species assignation. The continuous line represents Torosaurus latus morphospace. The dotted line represents Triceratops prorsus morphospace, and the dashed line represents Triceratops horridus morphospace.
