This is not a request on a single specific specimen, but rather of a general nature.
The "Pesciaia" ("Fish Pond") in Bolca near Verona is easily Italy's largest deposit of fossilised fish and other minor fauna, and fossils from Bolca are present in countless museums and private collections worldwide. The owners maintain their own local museum and actively sell specimens (I bought my first item there as a child, some 65 years ago), although not through the web - nearly unbelievable those days. You can only buy at their shop.
Now to the question: has anyone ever encountered a fossil that was claimed to be originating from Bolca, but was then discovered to be a fake? I would not elaborate now and here on the reasons for me wanting to know. Let's say I suspect someone is taking advantage of the owners' lack of familiarity with the digital world.
