ZPT-TB The Trilobite

The Trilobite is an entry-level fossil preparation tool, developed to provide an affordable air tool specifically suited to fossil preparation. Although not as powerful or refined as our ZOIC PalaeoTech PRO range of pneumatic tools, the Trilobite is multipurpose, robust and precise. It is an all-rounder air pen designed to cover everything from moderate matrix removal to fine work.

Optimal Operating Pressure: 4-6 Bars (58-90 PSI)

Weight (Including Hose): 270g

Dimensions: 148mm length, 16mm diameter (5.8" long, 0.6" diameter)

Air Consumption: 17lpm (0.6CFM)

Noise: 80dB

Connections: 1.5m braided air hose with Euro Connector

On/Off Mechanism: Twist Valve

BPM (At 6 Bars): 31,500

The ZPT-TB Trilobite represents the best value fossil preparation tool in its price bracket on the market. 

The Trilobite is a modified version of a commercially available engraver, allowing us to produce it on a tighter budget than our handmade, bespoke air pens in the PRO Range. We are able to pass on the benefits of these savings direct to the customer, along with all of our experience in what makes a fossil preparation tool useful, durable and great to work with. There are many similar-looking unmodified versions of the same engraver being advertised as fossil preparation tools - these won't have the same durability or longevity as The Trilobite. 

  • Tungsten Carbide Stylus (stoneworking grade)

  • Hardened stylus guide bushing to maintain precision for years to come (no wobbly stylus!) and ensure all power is directed forward 

  • Full frontal exhaust with modified air galleries to reduce noise. Easily fit on an o-ring (supplied with tool) to diffuse the exhaust when working on more fragile fossils.
  • Easy, low-cost maintenance
  • Wide adjustable pressure range - more power or more precision achieved with ease!
  • No bells, no whistles, just a pen that will see you through the majority of your fossil preparation needs. 

ZOIC PalaeoTech apply many of the same techniques to this tool as we do our PRO range. The Trilobite is a quality tool quite unlike any other in the same price range. The design is deeply simplified compared to our PRO range, but it was important to us to produce something that we could be proud of, yet manufactured on a much tighter budget. Wherever a feature really matters for durability and usability in the demanding task of fossil preparation, we have applied precisely the same technologies that we do in our PRO range to give you excellent value for money.

The Trilobite is a low to mid-powered Pusher-Plate Driven tool, which means that it is powered by compressed air pushing a spring which in turn pushes the stylus in and out many thousands of times per minute (31,500 give or take!). This produces a gentler action than Impact-Driven tools and so is suitable for working with more delicate fossils, and those sensitive to vibration. It will be slower work than the ZOIC Chicago on harder rocks or when removing a lot of overburden, but it is capable of tackling any job - and on a tight budget.

Sounds too good to be true? Nope! It's just an amazing price for the same ZOIC PalaeoTech quality and customer service that you know and trust. We take enormous pride in our product range. Spares are affordable and always on hand so you'll never be without even in the decades to come.

In the box:  User Manual, 1.5m braided hose with Quick Connector, Air Tool Oil, Silicone O-Ring Grease, 1x protective scribe sleeve, Maintenance pack of spare pusher-plate o-rings and spare Diffuser o-rings.

How does the Trilobite compare to other tools?

The Trilobite is exactly the same in terms of power, style and function as the ARO air scribe which you may have heard of, except our version is modified for use and durability in fossil preparation. The ARO air scribes were popular in fossil preparation, as they were for their intended use as an engraver before production ceased. Variations of tools based upon the ARO (some like-for-like clones) have been made over the years including the PaleoAro and Krantz W224. We use one of these as the base model for the Trilobite, modifying it by stripping out any non-durable components, and replacing them with 'fossil prep friendly' ones - this allows us to keep our prices exceptionally low for the quality and functionality of tool. If you want to learn more about how the Trilobite fits in with the rest of the ZOIC PalaeoTech range, read more here. 

air compressor

This kit comes with a 24l OL244/24 NuAir TECH Air Compressor - known for its quiet (66dB) operation, a good match for The Trilobite. The NUAIR Silent TECH OL244/24 24l Direct Drive Air Compressor is a powerful little air compressor for its size.

NuAIR Silent TECH OL244/24 24l Direct Drive Air Compressor

Tank Size: 24l

Motor: 0.7kw (1 HP) Induction

Air Capacity: 200L/min (7.1 CFM)

Weight: 21kg

Dimensions: 595 x 260 x 580 mm

Input Current: 13A

Noise: 62 dBa

Max. Pressure: 8bar (116PSI)

Oil Lubricated: No

Running at only 62-66dBa, the noise can be overpowered by a little background music! Oil-less design means low maintenance and no risk of oil spillage. Features include thermal overload cutout, pressure regulator and dial and Euro female quick-connect.

Personal protective equipment

Although probably the least exciting part of the kit, PPE is essential in fossil preparation. 

  • FFP3 Dust Mask

  • Safety Glasses

This kit comes with an FFP3 face mask (equivalent to N99), which is recommended as a minimum for fossil preparation. Not all face mask filters are created equal! Lighter duty or surgical face masks won’t prevent you from inhaling rock dust as the particles can be so small. Typically used in the chemical and pharmaceutical industry, these masks are ideal for keeping you safe.

Please always wear a mask. Silicosis is a lung disease caused by breathing in silica particles (silica is a major component in sand and many rocks), which causes scarring of the lungs. Some fossiliferous limestones set underwater, and if you were to inhale that rock dust, you can imagine where it starts to set!

Our ZOIC PalaeoTech fossil preparation starter kits also come with safety goggles to protect against airborne rock chips and dust, as well as ear defenders to protect from the noise of the compressor. 

*Please note that PPE may vary from that pictured, but the grade and level of protection will be exactly the same. Depending on supply, we use different brands, colours and styles, but we always ensure that all PPE is conformable to standard.
