FIGURE 6 in Identifying tooth position of isolated teeth of sparassodonts (Mammalia: Metatheria) using geometric morphometrics
FIGURE 6. Inter-locus variation in the M1-3 of Sparassodonta as shown by the Procrustes-transformed coordinates of the geometric morphometric analysis. (A) Superimposed differences between tooth loci in the Procrustes-transformed coordinates of the average shape of M1 (large gray circles) and M3 (small black circles). The other three images show deformation grids from the average shape of all 114 examined specimens relative to the average shape of (B) M1, (C) M2, and (D) M3. Differences between loci are magnified by a factor of 3 to better illustrate patterns of variation.

Plot of shape data (as regression score; see Drake and Klingenberg, 2008 for definition) versus natural log centroid size for all teeth of known locus in the trigon + talon dataset, showing the allometric signal in the data and the slight clustering of the teeth by locus.
