Figure 3 in Bone surface texture as an ontogenetic indicator in long bones of the Canada goose Branta canadensis (Anseriformes: Anatidae)
Figure 3. Results of the cluster analyses of bone landmark characters. The distance metric is normalized percent disagreement. Complete linkage method (farthest neighbour). All specimen designations are DMNH catalogue numbers. The numbers in parentheses represent ontogenetic stages. Femur: DMNH 78500 differs from 'All Others' only in the lack of character 10 (medial scar for M. flexor perforati II and IV). Tibiotarsus: DMNH 83058 differs from 'All Others' only in the lack of character 13 (peroneal sulcus). Humerus: DMNH 78603 differs from 'All Others' only in the lack of character 12 (bicipital crest).

D, circularly orientated oblique channels in outer regions of fibrolamellar cortex (DMNH 83589, femur section d). B, blood vessel with erythrocytes; L, lymphatic vessel; M, medullary cavity; P, osteogenic layer of periosteum. The space within P is a preparation artefact. Scale bars: A, D = 230 µm; B = 50 µm; C = 92 µm.

Figure 5 in Histological study of the jaw teeth in the Devonian actinopterygian †Cheirolepis canadensis (Whiteaves)
Figure 5. – Details (ground sections) of the vascularized bone in the jaw of †Cheirolepis canadensis. A. Several areas of the jaw show layers of vascularized bone with osteocyte lacunae. Scale bar = 50 μm. B: Detail of bony tissue with a secondary osteon (black asterisk). The white arrows point to osteocyte lacunae and arrowheads point to a cementing line between primary bone (pb) and the secondary osteon. Scale bar = 20 μm. C: Detail of bony tissue showing the spindle-shaped osteocytic lacunae. Scale bar = 25 μm. Inset: detail of an osteocyte lacuna with its ramified cytoplasmic canaliculi. Scale bar = 10 μm.
Figure 4 in Histological study of the jaw teeth in the Devonian actinopterygian †Cheirolepis canadensis (Whiteaves)
Figure 4. – Virtual section (3D-tomography) through the long axis of the jaw of †Cheirolepis canadensis (sub-sample c; see Fig. 1A for location) showing for each tooth the dentine walls, the acrodine cap (white arrows) and the pulp cavity (*). Scale bar = 500 μm.
Figure 3 in Histological study of the jaw teeth in the Devonian actinopterygian †Cheirolepis canadensis (Whiteaves)
Figure 3. – Thin sections in a jaw of †Cheirolepis canadensis (MHNM 05-340) observed in transmitted natural light. A: Longitudinal ground section of fragment a (see Fig. 1A) showing the two series of teeth: the larger ones (= the fangs) (*), located lingually, and the smaller ones (arrowheads), located labially. Scale bar = 200 μm. B: Section of fragment b showing an axial section of a fang. The arrowhead points to the dentine ankylosed on bone. Scale bar = 50 μm. C-D: Two cross-sections showing details of the larger teeth at different levels. C: The wall of the tooth pulp cavity is crossed by vascular spaces. Scale bar = 50 μm. D: The walls of the pulp cavity are irregular. Scale bar = 50 μm. E: Detail of a large tooth and two small teeth. The section crosses the teeth halfway between their base and their tip. Scale bar = 25 μm. F: Detail of the contact of a tooth with the supporting bone. One can see the odontoblastic canaliculi of the orthodentine. The arrow points to an osteocyte lacuna. Scale bar = 25 μm. G: Cross section of a small tooth showing the odontoblastic canaliculi of the orthodentine. Scale bar = 25 μm; inset: detail of the odontoblastic canaliculi. Abbreviations: ac = acrodine; bo = bone; de = dentine; pc = pulp cavity; vc = vascular cavity.
