Figure 5. Serpula israelitica. (A) Cross-section of the tube wall flaked in layers of different thickness. Scale bar 100 µm. Sample Noto 10G. (B) Detail. Scale bar 20 µm. Sample Noto 10G. (C) Prismatic crystals from the tube wall ordered in a lamellofibrillar structure partially obliterated by organic matrix within the prisms. Scale bar 10 µm. Sample Noto 10G. (D, E) Ventral and lateral view of a mineralized tabula closing the posterior end of a broken unattached distal end. Scale bar 1 mm. Sample Ciclopi 2G. (F–H) Progressively closer views of a tabula in cross-section showing a sphaerulitic prismatic structure. Scale bars 500 µm (F) and 100 µm (G, H). Sample Noto 10N. (I) Abundant organic matrix overlying the outer surface of a tabula. Scale bar 5 µm. Sample Noto 10N.
