Hey guys I came across this fossil on the internet. I dont think this is necessarily fake, but what are the chances this fossil has had some restoration or frabrication done?
Pretty easy to do. This method works with almost all soft and not too porous substrates. So not only for Messel but also for Frauenweiler (Oligocene, Germany). Even Green River material (from the split fish layers) could work (here I would not remove the substrate mechanically but with diluted acetic acid). I also prepped these small fish from Frauenweiler with the transfer method.
