Fossil preparation / enhancement with the help of heat
FranzBernhard posted a topic in Fossil Preparation

How to Recognize Fossil Fabrications - The Fossil Forum My hypothesis is, that this specimen was baked (as a whole or only superficially, with a blow torch, for example, possibly several times) to promote flaking off of the matrix.
