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.


Warranty: 12 month warranty covering manufacturing faults and defects.

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 Pferd MST31, PaleoAro, Krantz WS 224. 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. 

Once you've got your Trilobite air scribe, you'll want to know how to use and maintain it. We know that not everyone loves reading user manuals, so to make it easier we have video tutorials. Have a watch of our YouTube video below!

Received this as my first air tool, wow! As a recent convert to fossil prep I am really pleased with the performance of the Trilobite. I have been using a Dremel 290 with attachments from Zoic and this seemed an ideal next step. Must admit though, Hubby isn't to pleased that I've 'stolen' his compressor.

An absolutely AMAZING piece of kit! Extremely budget friendly with excellent craftsmanship and life span! It’s an extremely sleek and durable design which allows it to turn itself off if too much pressure was applied or air flow restricted, and as soon as the pressure is relieved or air flow is restored all you have to give it is a light tap and it will squeal to life! Literally! And although vibration resistant gloves (gardening gloves will do) and ear protection are recommended, when I first started it up I was surprised at how quiet it was and how small the vibrations were! Although I’d definitely wear gloves and ear protection for prolonged use. And although at first I was inexperienced (it is fool proof though and Ive been studying how to be a fool my entire life!) and the tool would drain my tiny compressor from 6bar down to 4bar (recommended range) in 2 minutes, once I learned how to balance it out I can get a good 15-20 minutes in between each 30 second refill! And despite being a budget tool it had a surprising amount of power being able to chew through tough sediment from Yorkshire! The pack also provides spare O-rings, silicone grease, oil and even a different tip! The best starting rig available! (Especially when combined with ammonites from Yorkshirefossils.com :)

I just wanted to thank you for the excellent service and compliment you on your Trilobite air pen. Very reasonable price and precise performance. I've been doing fossil prep for almost 40 years and this tool stacks up excellently against all my other air scribers. Not just for beginners as far as I can see.

Bought the Trilobite for Christmas last year, and I have been super impressed with the air scribe itself and all the support that Zoic Palaeotech provides to its customers.

This tool is such a game changer! No more hand and arm fatigue from the Dremel 290, and I don't feel the need to cover my ears now. Looking forward to my next shipment of nodules to arrive!

What a tool! I cannot recommend this highly enough. It tackles all of my fossils with ease and is so much fun to use. The guys at ZOIC have exceptional customer service and if this is the quality of their 'budget' tool, that speaks volumes for everything else they do. A couple of years ago I bought an aftermarket ebay fossil prep tool which fell apart (literally) in about 2 weeks and the seller didn't want to hear it. As a beginner, I assumed it must have been my mishandling but now I see the difference in quality between ZOIC and others, I think I just got swindled. ZOIC's tool just feels sturdy, good quality and robust - and it was cheaper too! Thank you ZOIC - keep doing what you're doing!

I had like a two month wait do to back order. The packaging for shipping wasn’t very good. The thing was loose in the box. And coming from England to the USA it should have been packaged better. But everything still works. I’ve only hardly got to use it but it work wonders on the dolomite I’m trying to get trilobites out of. I will more than likely order from them again.

I bought this as a replacement for my old engraver which had after years of service finally worn out. The Trilobite is so easy to use and has made prepping Whitby ammonites so much quicker, hours instead of days, it's so much quieter too and easier on the hands too. Well worth the money and I wish I had one of these earlier! Thanks so much for such a great product. All I need now is more ammonites to prep as I've run out!

An amazing little tool at a really amazing price. You can tell its got the ZOIC Palaeotech touch to it! I recommend to anyone wanting to add to their tooling, regardless of whether you're a beginner or not. Great scribe at a great price. Like the old Aro models but so so much better. Love the optional diffuse exhaust.

Bought for my daughter, she absolutely loves her new air scribe. Great piece of kit, can’t fault it. Fantastic customer service from ZOIC. Thank you for getting it here in time for Christmas.

Soy un principiante en el mundo de la preparación de fósiles, pero he encontrado en The Trilobite un gran aliado para mis preparaciones; su peso lo hace sentir muy comodo y ligero, aun despues de largas sesiones de preparacion y es tan versatil que puede tanto con rocas duras, blandas, rebajar pedazos de matriz (obvio teniendo en cuenta la carga de trabajo que puede realizar a tiempo) e incluso poder trabajar con costillas y oprnamentos relativamente delicados; La calidad de los materiales buena y la puntas hechas con Carburo de Tungsteno son excelentes para romper fácilmente la mayoría de las rocas sin sufrir prácticamente desgaste alguno. La atención a clientes también merece un 11 de 10 ya que todas las veces que he recurrido a ellos para alguna duda, repuesto o compra de otros artículos, se han esforzado en brindarme atención personalizada. Gracias ZOIC!!!
A great begginers prep tool

This tool is very versatile working on a range of hard/soft matrix. Great for beginners such as my son. Thanks!

I couldn't be happier with my Trilobite air scribe. I definitely recommend getting all the style stylus points as they all serve a purpose and come in handy! The tool itself is well crafted and does a great job removing material. I've wanted to get an air scribe for years and I'm so happy I chose this one!

Outil très performant pour les gangues dur, très bon rapport qualité prix aux vues des améliorations apportées, service après vente excellent, très professionnel. Petit conseil pour débutant lors de l enlèvement de gangue au dessus du fossile utiliser une loupe pour la précision, sinon c'est un impact garantie
