Abstract

Detailed SEM observations of live Halimeda incrassata collected in Biscayne Bay, Florida, show that calcification occurs in two basic stages: (1) uniform-sized, small aragonite needles, 1-3μm long, are precipitated in inter-utricle spaces and (2) these needles alter to anhedral equant aragonite approximately 0.1-0.5 μm in size. Early micritization in live algae may be an important process of skeletal alteration that has not previously been recognized. -from Authors
