Aragonite crystals within codiacean algae: Distinctive morphology and sedimentary implications
Perkins RD, Mckenzie MD, Blackwelder PL. 1972. Aragonite crystals within codiacean algae: Distinctive morphology and sedimentary implications. Science. 175(4022):624-626
Bottom sediments and cores of mud banks taken from, principally, the shallow waters of Florida Bay, Everglades National Park (Everglades National Park),were used to conduct studies of single crystals of aragonite within Codiaece algae which revealed characteristic crystal forms produced by two distinctly different modes of calcification. Diagnostic serrated crystals (1 micrometer in length) of aragonite originating within the extracellular sheaths of capitular filaments are incorporated into modern lime sediments. Intracellular calcification within Penicillus dumetoses, previously unreported, is represented by doubly terminated aragonite crystals ranging in size from 48 to 160 micrometers. Study Type: Qualitative; Gear Type: Cores; Habitat: Surface and subsurface lime muds; Biological Component: Codiaece algae; Abiotic Parameters Measured: Sediment characteristics; Dominant Taxon/Taxa Studied: Penicillus dumetosus, P. capitatus, Udotea sp., Rhipocephalus sp.
