Homotrema rubrum


Life habit and the waves and currents which distribute the sediments control the distribution of Homotrema in modern carbonate sediments on the Bermuda Platform. Homotrema provides a good measure of proximity of the reef as it decreases in abundance systematically away from it. The species is an excellent indicator of the direction of transport of sand-sized carbonate shoal sediments on the Bermuda Platform. It's distribution in sediments determined that sand-sized shoal detritus is dispersed a long distance seaward down the Bermuda slope. In contrast, the shoal detritus is not transported very far from the lagoon, it can also be useful for interpreting Pleistocene land exposed sediments.
