Abstract	Density banding in coral skeletons can provide for reconstruction of the coral's growth en. vironment over long periods. The physical differences between low and high density portions of a skeletal band are not well understood. The skeletal architecture of M. annularis from Southeast Florida, the Florida Keys, St. Croix, the Bahamas, and Mexico was compared in X-ray revealed high density (HD), low density (LD), and stress HD bands. Density changes arose from differences in the size, but not spacing, of exothecal structural elements (horizontal dissepiments and vertical costae). Endothecal architecture size (e.g., columella, dissepiments, septa) was relatively constant between density band types. Results have implications for studies of coral growth, sclerochronology, and isotopic/trace element composition.
