Chert News
sorted according to subjects:
Higher
Plants, Algae, Fungi,
Nematophytes, Cyanobacteria
and Microbes, Crawling creatures, Non-biological phenomena
For the convenience of the reader less acquainted with the
plants in
the
chert, catchy labels, set apart by colour, have been put on some of
them.
This is to indicate the diversity of the
inhabitants of this
Lower Devonian terrestrial ecosystem liable to occasional flooding.
Issues covering more than one subject are listed accordingly.
