Preparing Phacops PD

Recommended Posts

Fossil-Hound

I have by good fortune acquired a few decent Devonian Phacops trilobite specimens from the Penn Dixie Quarry in Hamburg, NY. One particular rock has a few decent Phacops embedded directly in the rock. I wanted to know what the steps are for preparing these fossils, or if I should just send them to a preparer. Please provide any advice you can. Thank you. I have a bunch of fossils and am new to the preparing process.

Well, my basic technique is to dig a trench around the trilobite, Trying to stay away from the trilobite itself. 

This can be accomplished using hand tools,  air tools, or electric tools.

Then, I usually use the air abrasive to remove the thinner matrix from the top of the trilobite.


If there is allot of matrix on top of the trilo, then I will try to remove as much as possible without touching the trilobite, if possible.

 

Here are some examples of my work - not the best but passable.

If you search Trilobite Preparation on Youtube, you should get some hits on that. 

Watch and learn, grasshopper. ;)

Good luck.

First off this-

Secondly, try to prep something you do not mind being damaged. Damaging a trilobite because of inexperience will ruin your day..lol. Yes this is from personal experience.

Awesome! Thanks everyone! I have a few pieces I think I can practice on. Not many, but a few. :-)

Aren't spots like those associated with pigment?

@DevonianDigger how are you doing buddy?! Hey thanks. :fistbump: I have a bunch of shark teeth and vertebrae that I was going to mail out your way yesterday, but I was so caught up in homework. I'm in the middle of grad school (Computer Science Masters from Johns Hopkins University). My midterm is over on Friday, and I'll have a lot more time to play after that date. :megdance:

No worries man, I know how it goes. I just gave yours to the shipping guy yesterday, so it'll go out sometime this week. (I have a sweetheart deal with a family member for free domestic shipping, only downside is that it's not really on my timeline, it's on theirs!) Best of luck on the midterm!
