Abstract: 
Yolk-platelet crystals in A. calva, L. osseus and P. bichir have orthorhombic features with unit-cell dimensions as determined in electron-diffraction patterns of fixed, epoxy-resin embedded and thin-sectioned material. Electron-diffraction patterns, crystal projections and the unit-cell data make them extremely similar to the orthorhombic yolk-platelet crystals known for amphibians and teleosts. This observation fills a gap in yolk-platelet research and supports the view that the general architecture of yolk platelets was conserved for nearly 400 million yr. It follows that the peculiar platelet architecture itself has physiological significance.
