Fossil preparation

Increase the value of your fossil

Fossil preparation creates decisive added value for sales

The scientific and commercial value of a fossil, as well as its aesthetics, are largely determined by the method used to uncover it.

Tool

Hand tools, (compressed air) scrapers, etc. Gravers of various thicknesses of HW, fine blasting equipment with pure iron/calcium carbonate of various grain sizes

Aids

Security

Closed system, blast cabinets with dental exhaust system and micro-fine filter.

From “praeparare” (Latin: to prepare) is derived the work step that determines the result.

Fossil preparation has undergone a fundamental change in recent decades. Until the early 1980s, finds were prepared manually using gravers, scrapers and brushes, but since then instruments from dental laboratories have been introduced: Fine blasting and suction systems. Quality and aesthetics have improved considerably since then. On the other hand, there are pieces that are irrevocably lost due to their inadequate preparation.

Some fossils have not yet seen the light of day. Some collections are getting on in years and need a “refresh”.

The following is a look at workshops.

The preparation of wood maggot fossils from the 180-million-year-old Posidonia Shale requires precision and involves the use of X-ray imaging to non-destructively determine the position and preservation of the concealed skeletons. Mechanical excavation is carried out using chisels and more finely by means of compressed air gravers or fine blasting technology. Special pyrite preservation is essential to prevent the decay of many finds through oxidation.

Expertise

I gained my first experience as a taxidermist as a research assistant at the Geological-Palaeontological Institute in Tübingen. There I prepared fossils from the Messel Pit. These came from a student excavation in 1988 under the direction of Prof. Frank Westphal, in which I took part as a volunteer. Our action was a protest against the planned backfilling as a “garbage dump” at the time. In 1995, the world-class fossil deposit was the first in Germany to be awarded UNESCO World Heritage status.

My taxidermy still meets scientific standards today, which is why it is in demand from museums such as the Natural History Museum in Mainz. Wouter Südkamp reports on an unusual and successful result in the Fossilien-Journal (2023-02). Below is an excerpt from the article:

Remarkable preparations of fish

The rump of these animals is often covered with a hard, black, pancake-like layer of rock, which largely prevents dissection. Despite phosphatization, the proportions of the fossil fish have been distorted. To my knowledge, no one has yet reported whether it has been tried or even succeeded in removing the concretionary phosphate substance. However, the Tübingen geologist and Bundenbach collector Christoph Leins achieved this first with a specimen of Drepanaspis (8A) and then with Gemuendina in a laborious process (pers. comm. Leins 2021).

The complete Drepanaspis was re-prepared in approx. 38 working hours, whereby the black coating was treated with potassium hydroxide (KOH).

The preparation result now revealed plate structures that were previously hidden by the black coating (8E).”

Examples

I have great expertise in fossils from Bundenbach and Holzmaden.

Holzmaden Fossil preparation

Fossils from Holzmaden – fish dinosaurs, sea lilies and fish – are among my favorite objects. Fine blasting machines with different blasting materials are used here. You can find more examples of fossil preparation on my info page on Holzmaden fossils. I also specialize in the re-preparation of older specimens with potential as well as the restoration of specimens affected by the Pyritzerfall (“efflorescence”).

Bundenbach Fossil Preparation

Fossils from Bundenbach – crinoids, star animals, trilobites, fish, etc. – are my personal favorites. They captivate with their intricate details. My preparation tools of choice are fine scrapers, scalpels and needles. As the preparation is done under the binoculars, it is much more time-consuming than preparing fossils from other sites. You can find examples of my fossil preparation on my info page on Bundenbach fossils.

Cost of fossil preparation

If you are interested, please contact me and send non-binding photos by e-mail or WhatsApp.

If the fossil arouses my interest and I have the necessary capacities, you will receive a fee offer with a fixed price on this basis – without hidden costs. You can check this at your leisure. If you do not accept the offer, you will not incur any obligations.

The fee depends on the difficulty (location, matrix) and the resources required. An hourly rate of EUR 40 is calculated for Holzmaden fossils.

Partners

I cooperate closely with scientific institutions. I work as a taxidermist and restorer for numerous museums, including the natural history museums in Mainz and Göppingen.
