Information about my fossilsI do not ship on weekends. Sometimes orders may delay due to holidays, bad weather, customs inspection and I prepared and cleaned most of the fossils myself. That's why I can guarantee that it's not a fake. In the case of the Moroccan trilobites, I mention if any replacement or repair was used by Moroccan artists.Any fossil must be treated with a conservative unless it is calcite, hematite or other hard material.Each type of material requires a different conservatives. I use conservatives that are meant for it.-- AMMONITE PYRITE -- I never use any acid to remove the outer coating. Usually, phosphoric acid or hydrochloric acid is used. This method is totally devastating for ammonite and pyrite. I know because I used this bad way in the past. Sooner or later, a complete disintegration occurs and also loses quality and strength.Polished ammonite lasts much longer. The protective layer must also be used for pyrite ammonite. If not, the pyrite fossil begins to undergo oxidation and leads to devastation. For polished ammonite, I also use a special pyrite preparation.Some people think polishing and painting with a colorless varnish is the wrong way - and they are wrong. Every metal needs protection!Failing to do so, most fossils will begin to oxidize.oxidation = decay and devastation.
