Hi all just back from the N Yorkshire Moors. Found these plant fossils at Hayburn Wyke. I’ve prepped them a bit using a hammer and bradawl, but I’d love to tidy them up at bit more. My question is could either of these be improved with air pens etc, and if so does anyone know of anyone Bedfordshire based who be interested in doing them? Obviously very happy to pay whatever the going rate is. The first are in sandstone, and does seem to prep ok - I’ve done all this with a bradawl and hammer! Second is a hard siltstone. I’d love to expose more of the leaf if possible and just generally tidy it up a bit. What do people reckon?

Hi,

I would stick with a manual pick or small etcher so as not to lose what you have. Preserve with either diluted PDA or paraloid solution.
I do not use an air abrader, I thought they fire fine sand to remove unwanted matrix.
That is the last thing you want with plant fossils.

Hi thanks for replying. I hadn’t thought that about the air air abraider - good point! What about an electrical engraver? I’d keep going with the hammer and bradawl, but it’s not precise enough, v hit and miss, and I don’t think a manual etcher will do the job as the matrix is quite hard and really needs a bit of power behind it to remove it.

Hi

Look out for hobby electric engraver, as long as you don't run it for hours it should be fine, I think it comes with a fine point but you can easily get replacements when they go blunt. I have one and it does the job. I tend to pad it where you hold it as it vibrates and does your fingers no favours. It has controls to lower or increase the speed to suit the matrix. I use mine under a long arm microscope to be precise, for bigger specimens just rig a magnifying glass.

Have fun

Thanks for taking the time to reply - I appreciate it! Sounds like I need to get myself to Homebase then! 😺

If you can research the different makes on line so you know what to look for. Hobby shops or a tool shop. Can't say what make i have but it is a well known make. You could also search fossil prepping engraver.

Just been researching etchers online, and there’s so much choice out there, it’s hard to know what to go for. May check out some of the auction sites too to see whether there are any deals to be had! Thanks again for your help, and I’ll let you all know how I get on.

I believe those are ferns.  What geological age was this location?
