Article: Optimum preparation, preservation, and processing techniques for graptolite electron microscopy

Published guidance on the preparation of ultrathin sections of biological material rarely gives sufficient detail to enable fossil material in general and graptolite material in particular to be prepared to a consistently high standard. The crucial steps relative to pre-microtoming, ultramicrotoming, and post-microtome work, including museum storage, are described together with the 'tricks of the trade' that, taken in total, result in successful micrographs.
