Figure 6

Indentation stiffness and hardness measurements in Nereis jaw. The left panel shows a pixilated longitudinal section of the jaw tip; each pixel corresponds to an actual indentation measurement, the brightness being indicative of the local stiffness value. The circumscribed area highlights the region examined for gradients. The right panel presents plots showing the variation of indentation stiffness and hardness along the outer jaw curvature measured from the tip, which is at the top of the image. Specimen dimensions are 0.3 mm × 1.4 mm; pixel size is 20 μm × 20 μm.
