Rhynie Chert News
deutsche Version
This is a series of contributions mainly based on own finds of Rhynie chert,
    every one of them reporting some observation, interpretation, or discovery
        apparently not yet published in the scientific literature
            and occasionally contradicting established wisdom.

The first contributions were published
since 2004 at www.kieseltorf.de, a website launched by Ralph Kretzschmar (Chemnitz) and deplorably shut down in 2017. This series of numbered issues had begun as paper prints distributed in very small numbers since 2005, with every issue composed of text, pictures, and references being confined to one or two pages. This concise format differing much from the lengthy papers in scientific journals has been applied here, too. It is meant to be a means of spreading information quickly in easily comprehensible quanta, which would be virtually impossible with the conventional ways of publication. When www.chertnews.de started in 2010, the 35 issues available then were put in. Their number is climbing beyond 156 in 2020, and there will be more to come. They are supposed to make up the main part of this website.

Contributions with a mainly introductory or explanatory character are not listed here. They are accessible via Site map.
