Fig 3
Disposition of 25 landmarks on a skull of Didelphis albiventris specimen.
1 = midpoint of central incisors; 2 = posterior-most point of lateral incisor alveolus; 3–5 = canine area; 5–7 = pre-molar series length; 6–8 = first molar area; 9–11 = second molar area; 12–14 = third molar area; 15–17 = fourth molar area; 18–21 = temporal muscle insertion area; 22 = most posterior tip of the palatine; 23–25 = occipital condyle area.
