FIGURE 3. X-ray synchrotron microtomographic sections compared to SEM photos of artificially fractured conodont specimens. 1, Tomographic section of Epigondolella quadrata specimen A; 2-4, SEM photos of an artificially fractured specimen of Carnepigondolella carpathica (sample NA16). Both the specimens are sectioned in correspondence to the cusp; 5-6, Comparison between a tomographic section (5) and an artificially fractured (6) specimen of E. uniformis from the same sample (NA42). Legend: cu, cusp; wm, white matter; hp, hypocalcification; gl, growth lines.
