Identification Type Algae
Name Cyanobacteria
Distinguishing Features Blue-green
Description When preserved, cyanobacterial remains have a characteristic blue-green pigment. Filaments may or may not be visible. Occur in zones of rapid deposition and anoxia, sometimes associated with diagenetic minerals also formed in reducing environments. Likeliest to be found in very recent sediments, as oxidation of pigments occurs rapidly.
