Can anyone explain or provide sources on methods of fossil preparation during the 19th Century? I am interested in what tools, chemicals(if any), etc., were used to prepare fossils from the mid to late 19th century.
I recently read one of Beecher’s papers from 1893 with a drawing of the antennae and legs of the Triarthus he found in the pyritized Lagerstätte ein Rome NY and was curious how they prepped fossils at that time?
Also, when was air abrasion introduced?
Thank you
