Figure 3. Serpula israelitica. (A) Attached tube parts irregularly curved and widely encrusting a corallinae algal fragment. Scale bar 1 mm. Sample AM/91 2D. (B) Encrusting tube circular in cross-section, with smooth shiny surface and two evident lateral flanges. Scale bar 1 mm. Sample AP07. (C) Detail of smooth outer surface from the attached part of the tube. Scale bar 200 µm. Sample AP07. (D) Row of alveoles inside a broken part of the basal flange. Alveoles are equally sized and regularly aligned. Scale bar 500 µm. Sample AM/91 2D. (E) Internal view of an alveole showing a subquadrangular undulate contour and crystals paving the lumen surface. Scale bar 50 µm. Sample AM/91 2D. (F) Detail of alveole on its inner surface with elongate prismatic crystals irregularly arranged in an unoriented structure. Scale bar 5 µm. Sample AM/91 2D. (G) Encrusting tube still with its proximal end (arrow). Scale bar 1 mm. Sample AP 07. (H) Detail of proximal end of tube, circular in cross-section, weak and lacking ornamentation, separated from the rest of the tube by a narrow rim (arrow). Scale bar 100 µm. Sample AP 07.
