Hey everyone! Sorry it has been so long since I last posted. I have been so busy with school, family life, and lots of technical problems. But I finally was able to finish my video and I am so excited to share my work with all of you! This video is about my latest fossil cleaning, It is my favorite trilobite to date! It is actually a complete body fossil, not just a shell, or a piece of one. I did learn a few new things this time. I had some trouble with this one because the air scribe I have is not not suited for microscopic fossils, which is what I am cleaning up. Because of this I ended up damaging my fossil. A technique I am trying is to find the edges of the fossil and clean them out before I clean out the middle of the fossil. I am doing this because the air abrasive is basically a s sand paper in air form. The top of this trilobite is quite detailed, if I cleaned up the detailed section first it would leave it open to be hit by unintentional air abrasive and thus damaging it. So I left the top to be done last. This seemed to work well. Which is pleasing. Watch and see how it all turned out!
Hello everyone! Sorry that it has been a while since I posted. I have been so busy with school. Physics keeps me pretty busy lol! So I have been working on my trilobites. This time I found out that working with the air abrasive it can be good to point the air parallel with the grooves of the trilobite. This way I can maximize the removal of the matrix and minimize the removal of the actual fossil. Because the angle of the air abrasive is parallel the force vector has a minimal contact with the fossil and maximum effect. Check out my video and see what I was able to do! And a big thanks to the University of Utah for letting me work in their lab, and a big thanks to the Undergraduate Research Opportunities Program for sponsoring me to work on this project!
I got this eurypterid this weekend at a fossil show. Considering the price of the other eurypterids there I think I got a good deal at $30. But the reason I'm posting this here is because I want to know what or if I should do to clear some sediment off of the fossil. I haven't really done much with preparing fossils so I figured I'd hear what you all have to say. Thanks in advance.
So glad I joined the forum recently. Years ago, I was an undergraduate in PA in Geology, and finished some other degrees in Climatology along the way. Although my academic geology days are gone, I collected a lot and visited areas along the east coast, including the now defunct Fruitville Quarry for the Kinzers formation - and finally did some field work in Montana (I will post another thread shortly about a fossil I found in Elk Basin that I would love some pointers on). I found these bones in Maryland along the coast around 7 years ago. My notes are poor, but I believe them to be from the St. Marys formation (?) though please correct me if I am wrong here. My guess is from a field trip to Calvert Cliffs, or the area where the Mary's may outcrop. The matrix is a grey, very dense, putty/cement like clay that I remember sticking to everything. Over the years, it has dried forming a tough cement. I believe these are Whale. I would love some pointers on what you think I should do, if anything, to preserve and better display these pieces. I dread the idea of them slowly drying out and turning into dust. I have a few more small bones (finger bone maybe?) from the same location, one of which is a gorgeous brown tone. You can see the tone coming through a little bit on the larger rib bone but the clay material covers it up a bit - and fills some cracks along the side. The bones are very heavy. Should I work this with a toothbrush, an air abbrasive unit, a scribe.... and butvar-76 it? Any thoughts, comments, suggestions would be greatly appreciated. I have never done any prep. and have some great rough laying around with parts of trilobites, bones and other bits and bobs that would be great to work on! Note: I know the rib is rotated - I didn't want it convex-up as I would think it would stress it. - I don't know how to add photos efficiently to the forums yet... so I will add more images in reply posts.
