Missing the third dimension in geometric morphometrics: how to assess if 2D images really are a good proxy for 3D structures? [PDF]

open access: yes, 2014
Procrustean geometric morphometrics has made large use of 2D images for studying three-dimensional structures such as mammalian bones or arthropod exoskeleta. This type of use of 2D data is still widespread today and will likely remain common for several
