This is a series of brief treatises 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
The first contributions were published at
www.kieseltorf.de since 2004.
The series of numbered issues had been launched in 2005 as paper prints
distributed in very small numbers,
with every issue composed of text, pictures, and references being
confined to one or two pages. This concise format differing much from
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. The 35 issues
available in early 2010 and the following ones will be put in here,
where all together are supposed to make up the main part of this
Contributions with a more introductory or
generally explanatory character are accessible via Site map.
