What a difference prep can make! I was recently sent a picture from back home of my first trilobite fossil, received as a childhood gift. This picture really drove home for me how much detail can be lost in prep, and how being able to really look into a pair of 400,000,000 year old eyes is such an incredible experience. It’s kind of a bummer to think of how many lovely critters get scraped away for the sake of quick sale- much admiration for fossil preppers. I like to think that this one was a beginner’s first shot, and that they have gone in to liberate many more bugs from the limestone with dignity and grace. Pic: what I thought Crotacephalina looked like vs what it does…

Can't help with the initial question but when checking the seller's offerings I just had to spontaneously buy a fern fossil as it looked so amazing and the price seemed also very ok! I've never bought a plant fossil before but also never seen a Carboniferous fossil which looked so well preserved and colorful to me. Oddly I can't find any of these anywhere else on the web and hardly any information about the locality. Does anyone have any information about the locality or the formation? Greetings from Germany

Whitening of fossils with ammonium chloride is a common and effective method to enhance the contrast for pictures. Here you can download a short "how to do video" : https://www.researchgate.net/publication/287444709_Whitening_fossils_with_ammonium_chloride Ammonium chloride is water soluble - the process is reversible (if the fossil tolerates rinsing with water). Have fun Thomas
