Diatoms (Bacillariophyta)
Abstract The diatoms are one of the most easily recognizable groups of major eukaryotic algae, because of their unique siliciAed cell walls (frustules), which consist of two overlapping thecae, each in turn consisting of a valve and a number of hooplike or segmental girdle bands (1).

| Summary: | Abstract The diatoms are one of the most easily recognizable groups of major eukaryotic algae, because of their unique siliciAed cell walls (frustules), which consist of two overlapping thecae, each in turn consisting of a valve and a number of hooplike or segmental girdle bands (1). Well-preserved frustules are found in the earliest known deposits of fossil diatoms, from the early Albian (125 Ma) of what is now the Weddell Sea, Antarctica, but these diatoms bear no resemblance to modern diatoms in their morphology (2). |
