Figure 3

Comparison of SEM, TXM and polarized light images of the internal structures of a Tarbosaurus tooth near the DEJ: (A) SEM back-scattering image, (B) TXM image and (C) polarized light image captured using a 100 × objective.

The aquamarine color in this figure represents enamel birefringence and helps to identify the enamel region. (Scale bars: 10 μm.) (The bright dots in (A) and black dots in (B) and (C) are gold particles, which were used for image and system positioning.)
