Figure 8. – Tepexeichthys aranguthyorum. (IGM 12717b) A: Longitudinal section of a fin ray showing two opposite lepidotrichial hemisegments separated by gang material (black asterisks). Bony tissue is crossed by numerous osteoblastic canalicles orthogonal to the surface of the ray. B: Cross section of a fin ray showing numerous osteoblastic canalicles some of which being ramified (black arrows). C: Detail showing the ramified extremity of several osteoblastic canalicles (black arrows) and several osteocytes (black arrow-heads). Scale bars: A, B = 100 μm; C = 50 μm.
