BLOOM OF THE GIANT ANADYOMENE GIGANTODICTYON SP. NOV. (ANADYOMENACEAE, CLADOPHORALES) FROM THE OUTER SLOPE (25-50 m) OF THE BELIZE BARRIER REEF(1).

abstract：:The earliest known diatom fossils with well-preserved siliceous frustules are from Lower Cretaceous neritic marine deposits in Antarctica. In this study, we analyzed the cell wall structure to establish whether their cell and life cycles were similar to modern forms. At least two filamentous species (Basilicostephanus...
