English: Breakdown of the vascularization within the tip of the fin spine of Lophosteus (GIT 727-2). (A) and (B) are cross-sections of 3D renderings and scan data of slices 472–680 and 786–984 (thin sections are slices 580 and 880), respectively, to show how each layer of canals relates to each other. Orange, central vascular canal, cvc; Light blue, 1st tier canals, 1st; Dark Blue, median canal, mc; Yellow, basal canal, bc; Purple, 2nd tier canals, 2nd; Pink, 3rd tier canals, 3rd. 3D renderings of the surface of the spine also included in white at the end of each vascular canal. Color scheme is the same throughout figure. Scale bars for (A) and (B) are 250 μm. (C) left lateral and (D) posterior views. The locations of the virtual thin sections and renderings are labeled in red on the surface rendering of the spine in (C). Scale bars for (C) and (D) are 300 μm. Yellow arrows explained in text.
