Our TT Fossil Preparation Pen is a very versatile fossil preparation pen.

Evolved and produced by us specifically to meet the more demanding requirements of fossil preparation without compromises to other uses. Far removed from a basic industrial air engraver that was often pressed into service in the past, it has a far superior versatility and flexibility to produce the best fossil results. All the component parts are unique to our TT pen,

The TT pen includes

  • A considerably robust stylus with considerable tungsten carbide at the tip, for an extremely long life, in a grade suited to working with stone.
  • A refined nose, in hardened steel, gives great support to the stylus, enabling matrix removal at the finest level to be maintained. Fossil prep typically is done with the pen at a more acute angle increasing considerably the side load on this critical part.
  • A main body made from stainless steel, with a good grip, giving better control for both detailed work and fast matrix removal at fossil preparation angles and applications.
  • Lever switch for easier power control, balance and a lighter hose that can be easily adjusted for length.
  • Hand made here, we have 100% quality control and 100% total spares backup and service support.

The TT Fossil Preparation Pen is deceptively powerful for its size, while being genuinely capable of truly fine finishing work, with a surprisingly meagre air consumption. It has a wide power range and is easily and instantly varied for close or fast work. Very popular with users who prepare larger ammonites or multiple ammonite blocks and large vertebrates.

Stenopterygius sp
.  Upper Lias Lower Jurassic Whitby Yorkshire

Shown with areas in various stages of preparation from roughed out to near finished. This very large nodule contained in 3D, a skull, post cranial verts and a paddle of this large Ichthyosaur and was preserved in the typically very hard, heavily pyritic limestone. It was prepared exclusively with our TT pen from start to finish. The TT pen with its combination of power and finesse, meant that it was the ideal choice for fast, hard matrix removal and finishing. Note the specimens equally massive rostrum laying in the background.
