Biomineralization
) Sea Urchin Tooth: Chewing part of the sea urchin tooth. It is composed of thin fibers of low Mg calcite embedded in a matrix of small crystals containing high Mg calcite. The latter may have 30% or more Mg. For more information see Wang et al, 1997, Philos. Trans. R. Soc. Lond. B 352, 469-480. |
) Forming surface of human lamellar bone, showing the plywood like motif of the lamellae.For more information see Weiner and Wagner 1988, Annual Review of Materials Science 28, 271-298. |
) Ascidian dogbone spicule composed of a core of
amorphous calcium carbonate and an outer layer of calcite. For more information see Aizenberg et al, JACS 124, 32-39. |
) Neopilina mollusk shell, showing the apex which includes the larval shell, and the aragonitic prisms at the rim. Neopilina is a primitive mollusk with segmented body parts. |
) Mineralized collagen fibril from a turkey tendon viewed in TEM. The plate-shaped crystals are located in layers within the mineralized fibril. For more information see Weiner and Wagner 1988, Annual Review of Materials Science 28, 271-298 |
) Aragonitic otolith from the fish Lapillus, showing the spherulitic internal structure. |
