Permian Chert News
deutsche Version
This is a series of brief treatises based on own finds, unless indicated otherwise,
 of Permian cherts (including uppermost Carboniferous),
  every one of them reporting some observation, idea, interpretation, or discovery
    apparently not yet published in the scientific literature
       and occasionally contradicting established wisdom.

Every treatise consisting of text, pictures, and references is confined to a concise format of one or two printed pages, thus differing much from the lengthy papers in scientific journals. This 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. (A few contributions had been published at www.kieseltorf.de since 2004. Deplorably, that website is closed now.)

For critical comments on other work concerning cherts and fossil wood see Misconceptions and Errors and Mistakes .
The below list will be extended as long as novel observations become available
