Preparation Techniques for Material From The Posidonienschiefer (Lias Epsilon, Upper Liassic) of Germany

Abstract

The authors describe methods of mechanical and chemical treatment of fossils from the Posidonienschiefer (Lias epsilon, Upper Liassic, Lower Jurassic, south-western Germany). Special tools and techniques are discussed. The use of acids in the preparation of vertebrate fossils from calcareous layers gives very good results, better than any mechanical method of preparation.
