The lithopreparation workshop comprises:

• Severin Morelin the Palaeontology Building

• Vincent Rommevauxin the Geology Building

The lithopreparators prepared thin sections of rocks. They permit teams to analyse the composition of sedimentary rocks for throwing light on the depositional environment and the structure of fossils which facilitates identification and yields data relevant to understanding their growth. 

The preparation consists of gently grinding a rock sample or a fossil which has previously been cut and stuck to a glass slide.
