Abstract
A small rock reef, extending along the northeastern shore of Key Biscayne, Florida, for a distance of about 400 yards and seaward for 115 yards, has been found to be composed of a framework of fossilized mangrove roots belonging to the black mangrove, Avicennia nitida. The roots, now turned into calcareous rods, are embedded in a friable calcareous-quartzitic sand which may be quickly washed away by wave action along the seaward edge of the reef. In this manner, a lattice of roots in their original position is exposed. It is believed that this may be the first reported occurrence of the fossilization of mangrove roots. Radiocarbon dating indicates the age of the rods to be between 1000 and 2000 years.
