Dear morphmetricians,
I am new to the field of geometric morphometrics and have been
researching primate mandibular morphology in relation to diet. I have
landmark names and definitions for all of my landmarks except for three.
I have been looking around to see if there are proper names for three of
my landmarks along the symphysis. I made up "gnathion internal" for
landmark 13. I was hoping somebody here might be familiar with
mandibles. Landmarks in question are 13, 16, & 17.
Thank you,
Daniel Arrañaga
