Fig. 3 in Diversity of tissues in acanthodians with Nostolepis-type histological structure
Fig. 3. Third type of Nostolepis histological structure, with some scales formed entirely of a simple odontocytic mesodentine (A–C) and others an almost acellular, syncitial mesodentine (D). Vertical longitudinal sections. A. Nostolepis timanica (Valiukevičius 2003a: fig. 26A); LIGG, thin section 3375. B, C. Nostolepis platycrista (Valiukevičius 2003b: fig. 14B, C); LIGG, thin sections 3579 and 3582. D. Nostolepis paravolborthi (Valiukevičius 2003b: fig. 19D); LIGG, thin section 3556. Crown mesodentine slightly odontocytic in the lower crown only (the neck area). Scale bars 0.1 mm.
Fig. 2 in Diversity of tissues in acanthodians with Nostolepis-type histological structure
Fig. 2. Second type of Nostolepis histological structure, with maximum stranggewebe extent, exemplified by Vesperalia perplexa (Valiukevičius 2004: fig. 3A, B). A. LIGG, thin section 3678. A1. Vertical longitudinal section of scale showing long and dense stranglakunae with short processes and interspersed osteocyte cavities, with no simple mesodentine. A2. Wide ascending and radial vascular canals. B. LIGG, thin section 3679. B1. Scale in vertical transverse section; orientation of stranglakunae and superficial dentine tubules in an odontocytic mesodentine, and a dense concentration of osteocyte cavities in the apex of base cone (B2); stranglakunae and the vascular system of the right crown part (B3). Stoniškiai−1 borehole, Lithuania, Pridoli, Silurian. Scale bars 0.1 mm.
Fig. 1 in Diversity of tissues in acanthodians with Nostolepis-type histological structure
Fig. 1. First type of Nostolepis histological structure, with stranggewebe (posterior crown part), simple odontocytic mesodentine network (anterior crown part) and cellular bone (base). A, B, D. Nostolepis striata Pander, 1856 in vertical longitudinal sections. A. All types of tissues and ascending vascular canals (Ørvig 1967: text−fig. 5A); SMNH, thin section S 1044. B. Posterior part of crown with stranglakunae layer covered by a layer of odontocytic mesodentine (Gross 1971: fig. 2G); MNB, thin section 3658. D. Posterior part of scale containing a system of principal wide vascular canals, and a superficial layer of syncitial mesodentine (Gross 1971: fig. 6A); MNB, thin section 3935. C. Nostolepis terraborea (Valiukevičius 2003b: fig. 15C); LIGG, thin section 3644. Simple odontocytic mesodentine network and long stranglakunae in a scale without principal vascular canals. Scale bars 0.1 mm.
Fig. 6 in Diversity of tissues in acanthodians with Nostolepis-type histological structure
Fig. 6. Microstructure of scales of the sixth type of histological structure (not belonging to the Nostolepis−type). A. Nostolepis longipostera (from Valiukevičius 2003b: fig. 12A); LIGG, thin section 3594. B. Nostolepis minilonga (from Valiukevičius 2003b: fig. 17A); LIGG, thin section 3610. Multi−branched ascending vascular canals and network of non−lacunal dentinal tubules in crowns formed of a syncitial dentine with durodentine; bone in the scale bases contains only a few osteocyte cavities. C. Watsonacanthus costatus (from Valiukevičius 2003a: fig. 32B); LIGG, thin section 3302. Ascending vascular canals and the canaliculi network is slightly similar to mesodentine in the anterior crown part, and dentine−like in the posterior part, with one principal ascending branch per growth zone, and only a few interconnecting tubuli, mostly oriented upwards; cellular bone in base. Scale bars 0.1 mm.
Fig. 5 in Diversity of tissues in acanthodians with Nostolepis-type histological structure
Fig. 5. Fifth type of Nostolepis histological structure, with cellular unipolar mesodentine in crowns and cellular bone in scale bases showing the first and second order growth lines. A. Fecundosquama basiglobosa (Valiukevičius 2004: fig. 5A, B); LIGG, thin section 3683. Thin−lamellar deep base and low crown both of superpositional growth (A1) and rounded osteocyte cells in crowns without processe connections and unipolar outwardly emanated dentinal tubules (A2). B. Tchunacanthus obruchevi (Karatajūtė−Talimaa and Smith 2003: fig. 18B); LIGG, thin section 1333. The short unipolar dentinal tubules in a scale crown with areal growth zones and a base which continued growing after crown growth stopped. Outcrop 135, Tchuna River, southern Siberia, upper Llandovery, Silurian. Scale bars 0.1 mm.
Fig. 4 in Diversity of tissues in acanthodians with Nostolepis-type histological structure
Fig. 4. Fourth type of Nostolepis histological structure, with crowns composed of a bone−like cellular mesodentine, or possibly cellular bone similar to that in scale bases. Vertical longitudinal sections. A. Acritolepis urvantsevi (Valiukevičius 2003a: fig. 16F); a bone−like mesodentine developed in the lower neck and crown areas not occupied by the stranggewebe; LIGG, thin section 3350. B. Nostolepis adzvensis (Valiukevičius 2003b: fig. 7A); LIGG, thin section 3635. C. Monospina erecta (Valiukevičius 2003b: fig. 22A, B); LIGG, thin section 3535. C1. Crown tissues without vascular canals; osteocyte cavities connected to each other by short processes; crown tissue most similar to base bone. C2.
