Aim and subject
This presentation is meant to serve several purposes.
Thus it is...
... to quickly spread information on more or less important
observations and discoveries
resulting from non-professional
activities in palaeontology, preferably related to palaeozoic cherts,
... to draw the professionals' attention to the news
with the aim to initiate closer
inspection,
... to encourage lay fossil collectors to look for and address follies
and errors
in the established science.
Note that this presentation ...
... begins in an intentionally biased way, being centred around the
famous Rhynie chert,
... is extended to fossiliferous cherts and fossil wood from a few
other locations,
Also this presentation ...
... draws
the attention to non-biological phenomena relevant to
fossils,
as
level bands, cracks, surface
tension effects, mineralization
sequence, etc.,
... introduces some physics helpful
for understanding such phenomena
and deriving useful information from
them.
