Filamentous cyanobacteria preserved in masses of fungal hyphae from the Triassic of Antarctica
PUBLISHED Permineralized peat from the central Transantarctic Mountains of Antarctica has provided a wealth of information on plant and fungal diversity in Middle Triassic high-latitude forest paleoecosystems; however, there are no reports as yet of algae or cyanobacteria. The first record of a foss...
