Stunning specimens, beautifully prepped as always. 

The detail is exquisite! :envy:

Drooling, just drooling.

Fossil hunting is easy -- they don't run away when you shoot at them!

Not sure mere words can express the level of skill you have there. Amazing detail and work!! If more Moroccan preps were that nice, I would finally get to purchasing one.

It's not Moroccan, but nevertheless. We don't often see these available and less often how they are found and prepped... I was lucky to get one years ago and prep it recently, so I figured to update this topic with this Rochester Shale 6" long Arctinurus boltoni prep-series. 

 

Ventral side as found split in 3 large blocks of Rochester Shale:

First left side was prepped, to make a window:

Then all parts transfered, a large bulk of matrix from the top removed and bug slowly prepped out:

Not the best break and in some areas the shale harder (with pyrite) that needed to be carefully removed and each tubercule carefully exposed, but turned not so bad, with only a small area of exoskeleton missing in the break, that needed to be restored.

 

In lab light:

Fantastic!
I’m glad you decided to keep the very tiny Dalmanites pygidium on the thorax... Gives it even more character.

Very glad to see this thread again! That's one gorgeous bug! :wub:

 

When working around the tubercles do you prefer to use a scribe or abrasion?

Thanks all!

Actually both. Scribe is used to make prep go faster, usually theres some debris, harder parts of matrix or pyrite traces just over the skin. Blasting around the tubercles can easily pop them off, if too much pressure or too aggressive abrasive is used, so it's best to balance between scribes and abrasives.

I should really have a go at the one I have in the basement but is a big commitment in hours and probably only about 90% complete

Again not Moroccan. :) Little juvenile Isotelus from the Walcott-Rust Quarry. I love these, they prep almost like Oufaten material.

:wub::wub: This thread constantly amazes me, another phenomenal trilo! 

 

Do you use some sort of rotary tool to smooth out the matrix?

Very nice! Were you planning to abrade some of the residual matrix from the segments and extend the pleurae to their rounded tips?

Yes, matrix is grinded.

I prefer not to blast these. There's a trick or two to make it 0.1% nicer, but I'll just leave this one as it is.

Awesome bug and work... in envy that you managed to get a complete one. I've had a few but at least one genal is always partial

Ty! It's in a strange position, so I was expecting problems, but in the end turned complete with pathology (left genal and on pygidium).
