At the Bristol Ice age Project, the processing of thousands of microfossils makes it important to have very good methods and materials to get protecting such an immense range of specimens. We all present a basic tool to get cutting a large number of standardsize Plastazote® foam safeguards which will save time and minimises repetitive pressure injury to those that have to do the position.

Introduction

Efficient conservation methods are necessary in fossil preparation. With the Bristol Ice age Project (BDP), good preservation methods are vital to preserve the ready minute microfossil specimens. Protecting them intended for future make use of by research workers is no easy task, for their delicate character and volume. As Smith (2007) mentioned, " microfossils can be very quite a few...... curation costs per product add up quickly for some materials... … a poor storage space system will take up a disproportionate quantity of space in a cramped collection". With the BDP new methods of specimen storage were developed to be able to protect the specimens, to increase the available space also to facilitate use of specimens. One of these new strategies is the custommade lining of most specimen enclosures with Plastazote®, a shut down cell cross-linked polyethylene foam, protecting these kinds of extremely vulnerable specimens by being demolished by being loose in credit card or plastic-type boxes. The standardization of box sizes and the ought to create thousands of pads for these people involved a painstaking activity that however, most prepared volunteer ultimately refused to complete. The repeated job of cutting circular pieces of Plastazote® with a slicing punch offered the user very sore hands. With this paper the authors identify the materials and strategies used to produce a simple and extremely effective tool to slice thousands of standard-size pieces of cushioning material.

brate fossils on the scale that virtually requires the use of a microscopic lense (Madsen 2009). Even though this may not be the case for any fossils recovered from the BDP´s acid control, we tend to contact them microfossils. With the average size between 250µm to fifteen mm, the fossils taken care of at the BDP are very sensitive, not only due to their size and taphonomic background, but as well the outcomes of acid planning methods; this all makes them extremely friable and thus in need of right conservation treatment. Specimens are picked and placed separately into obvious round Polystyrene containers with an external size of twenty mm and internal diameter of 16 mm (Figure 1).

something similar, but for reducing thick cushioning materials. A small Clarke® Arbor press was ideal for this kind of, as it contains a long central post that can be adapted with almost any kind of bit/tool and it runs by a basic smooth handle action that multiplies the force and for that reason reduces the amount of force exerted by the user. By creating a punch bit with the specific dimensions of the standard size boxes used at the lab and installing it for the Arbor press post, most padding producing problems would vanish. We present a step-by-step explanation of the production of this device....
