Wrangellian Posted March 21, 2012 Share Posted March 21, 2012 Ooh, Henry, that first Damesella looks like someone took a wire brush to it! Maybe the 2nd one hasn't been so deeply scarred that it will look nice with the proper techniques applied. Interesting specimens anyway, congrats... I want one!

Yep the first one is scarred with a wire brush, as you said, but the second one has just been soaked in vinegar... but then again it looks like the right genal spine took a hit from a chisel. Well, at least it can still be further prepped Is there any way to remove the effects of a wire brush? Can anything be done to make the markings less obvious? Because besides those marks the trilobite is a pretty one Link to comment Share on other sites More sharing options...
Sinopaleus Posted March 25, 2012 Share Posted March 25, 2012 (edited) Okay, maybe I was wrong... I left this guy out, and he is also one of my most prideful newbies, so now there's four.

Because besides those marks the trilobite is a pretty one I'm not sure.. the only thing I can think of is the techniques the pros use like the air abrasive - they are expensive but the only thing I have seen work wonders. I'm sure it would tidy up the matrix around the trilo but not sure how much use it would be on the trilo itself unless there is still some matrix on it. Maybe vinegar or similar acid if the matrix is a limestoney material but the bug isn't? You're getting quite the collection there, nice variety. Keep them coming.

Caleb Posted March 26, 2012 Share Posted March 26, 2012 Here is a Ceraurus aff. pleurexanthemus from the Galena Formation of Southeast Minnesota. The "aff." stands for affinity meaning that it closely resembles the C. pleurexanthemus but may(or may not) be a different species pending further research. This specimen was prepared by Gerry Kloc.

Caleb Posted March 27, 2012 Share Posted March 27, 2012 Thanks! I believe there is a paper in the works/almost done that will make some sense out of the Midwest Ceraurus/Gabriceraurus. I am very much looking forward to the publication of that paper. I should find out more about it at MAPS. Caleb Midwestpaleo.com Link to comment Share on other sites More sharing options...
Caleb Posted April 1, 2012 Share Posted April 1, 2012 (edited) Here is the Dolichoharpes reticulata I posted earlier in the post all prepped out. Prep work was done by Gerry Kloc and it was photographed by Tom Whiteley. My initial find and photograph of the specimen unprepped(just prepped enough to show it was complete then given to the pro).

mikeymig Posted April 1, 2012 Share Posted April 1, 2012 This very complete and well preserved Eldredgeops rana (1.9") is called The Becca Bug. It was found on my daughter Rebeccas birthday (11/05/2008) in Livingston County, New York. Middle Devonian, Moscow formation, Windom Shale. Its not a rare trilobite but its my favorite in the collection. There are no repairs or restoration! mikey Many times I've wondered how much there is to know. led zeppelin Link to comment Share on other sites More sharing options...

trilobiteruss Posted April 5, 2012 Share Posted April 5, 2012 Well after my trip to MAPs this past weekend I came back with another trilobite prize for my collection: Acanthopyge consanguinea Order Lichida, Family Lichidae Lower Devonian Size About one inch long (large for these!!!)

trilobiteruss Posted April 5, 2012 Share Posted April 5, 2012 Very cool, that's not an often seen bug from OK! Thanks Caleb, yep it is pretty rare from the Oklahoma material. I found a real deal on this one which had been on my wish list of Ok bugs. It was one of the larger ones too at an inch plus. Very pleased I could get it and get my Ok collection beefed up a bit! russ Link to comment Share on other sites More sharing options...
xonenine Posted April 7, 2012 Share Posted April 7, 2012 on Nathan / squalicorax's recent visit, he brought me a large flexicalymene trilobite in matrix to allow me to learn some prep as well.He was even more helpful when I was hesitant about damaging the specimen, and encouraged, I have uncovered a good portion. When time came to split the specimen height-wise for display, I chose my spot carefully and was rewarded with another flexicalymene almost twice as large! It is so sharp, I will glue the negative back on and prep both sides, it will have to stand on an edge. thanks again Nathan, this is a fun perfect piece to work on, and a real first for me Carmine "Your serpent of Egypt is bred now of your mud by the operation of your sun; so is your crocodile."
