Right dentary of Tupaia glis lacernata (Institute for Geoscience Paleontology MaÜ 70).
The reflecting facets at the steep flanks of the molars are resulting from tooth-to-tooth wear).
Table 1.
Data are summarized grouped by age class.

Digital analysis of a feces sample.
(A) scan image of chitin particles spread at the glass plate of the flatbed scanner. (B) abstracted chitin particles in white; all foreign particles are removed. (C) processing and analysis by Image-Pro Analyzer, measuring greatest length, width, and surface area.
Fig 3.
Number of particles (B) and particle sizes (A) per sample. Samples (x axis) are grouped by animal and colored by age class (red/left: Juvenile, green/middle: Adult, blue/right: Senile). The distribution of the number of particles (A) is shown on logarithmic scale.
Fig 4.
Number of particles per sample (A) and particle sizes (B) compared between age classes. P values are from linear mixed effect models accounting for nested random effects (samples under animals). The particle sizes in the model are controlled for number of particles per sample and the interaction of this number and age class and the main effects for age class are reported.
Fig 5.
Proportions of large (A) and small (B) particles in each sample. Samples are grouped by animal with different shades to visually differentiate between the two. P values are from logistic mixed effect models accounting for nested random effects (samples under animals) and controlling for number of particles per sample and the interaction of this number and age class. Reported are the main effects for age class.
