The user This manual is designed for the use of geo-scientists with an interest and need in developing palaeobiological materials as a potential source of data. To meet this objective practical procedures have been formatted for use by both professional and semi professional students with an initial understanding of palaeo biological research aims as a primary source of scientific data. I have attempted to provide an explanation and understanding of practical procedures which may be required by students undertaking palaeobiological projects as part of a degree course. The layout of this manual should be particularly beneficial in the instruction and training of geotechnologists and museum preparators. Graduate students and scientists requiring an outline of a preparation procedure will also be able to use the manual as a reference from which to assess the suitability of a procedure. This manual is also intended for use by the "committed amateur". Many of the techniques described in this manual have been devised by non-palaeontologists, and developed from methods used in archaeology, zoology and botany, as well as other areas of geology. A considerable number of the methods can be undertaken by the amateur, and in the case of many of the field procedures, should be used. This will ensure that specimens and samples can be conserved in such a manner as to facilitate any later research, and not invalidate the results of subsequent geochemical analytical techniques which might be employed.
