Figure 3. – Lepidonotothen squamifrons. A: Horizontal section (microradiography) showing several cross sections of teeth on the right and the lower jaw on the left. B: Horizontal section (microradiography) taken lower than Fig. A. The wall of the pulp cavity of the central tooth (*) is crossed by vascular canals. We can see three very young non-functional teeth (arrowheads). C: Cross section of the lower jaw (microradiography) showing a young erupted tooth (arrow) and a fall- en tooth (*). D: Detail of a functional tooth showing the unmineralized ligament (arrowhead). E: Cross section of the jaw showing a tooth bud inserted in an alveola (arrow), beside a functional tooth (arrowhead). F, G: Cross section of a tooth (respectively in transmitted natural and polarized light. The more lateral dentinous tissue is striated, indi- cating the presence of odontoblastic canaliculi. (Scale bars: A, D = 250 μm; B, F, G = 150 μm; C = 500 μm; E = 1 mm. (A, B, F, G: 259 mm TL; C: 415 mm TL; D, E: 190 mm TL). ... : Published as part of Meunier, François J., Lecomte, Frédérique & Duhamel, Guy, 2018, Some histological data on bone and teeth in the grey notothen (Lepidonotothen squamifrons) and in the mackerel icefish (Champsocephalus gunnari) (Notothenioidei; Perciformes; Teleostei), pp. 91-97 in Cybium 42 (1) on page 94, DOI: 10.26028/cybium/2018-421-009, http://zenodo.org/record/13475455 ...
