Re: Holzmaden Formation?
the official lithostratigraphic scheme for the German Jurassic is not
yet released, however a draft is published here:
The Holzmaden beds belong to the Posidonienschiefer Formation. Previous
schemes are dating back to the 19th century and are highly overfraught
with local synonyms and homonyms (hence the "official release"). The
term "Formation" was not used in the old names.
Posidonienschiefer means "Posidonia shale" (although the bivalve
"Posidonia bronni" is now known under various names, including
Steinmannia bronni or Bositra parva - don't know which one is presently

I always thought it was Posidonia Shale Formation.
When someone says a fossil originated from Holzmaden, what geologic
formation would that be? It's weird how they no one ever
seems to specify.
The obvious guess would be that they're referring to a "Holzmaden
Formation" named after the town, but Googling that brings
up a mere 58
results, with one of the top 5 being about the Pseudoscience Which
Must Not be Named. That number sounds suspiciously small for such a
well-publicized fossil site, so I'm having doubts. What *is* the
formation of origin for "Holzmaden" fossils?
