Kehbe Posted December 27, 2011 Share Posted December 27, 2011 (edited) Mo. Jackson co. KCMO Pennsylvanian, Iola Form. These were laying on top of this block that was laying in the debris slope of this cut This is the Muncie Creek shale you see in the cut here. They look similar to Chonetes or Orthis but I couldn't find reference to Orthis in this area. I will keep looking though. As you can see, the smallest of them is different than the others. Not sure what it is either but I am researching it. I assume the grey color and crisp feel of these is because of the material they were fossilized with. Unusual to me was the fact that they were all on top of this large block, along with a few crinoid stems and other various shell fragments and bryozoan fragments. I am going to go back there and try to find a few more, I think they would look good under glass on black velvet in a gray frame. I would love to have a positive ID though to include a tag in the frame. They are nice and flat and so lend themselves to that. Plus provide nice storage! Hey Thanks for looking!

Missourian Posted December 27, 2011 Share Posted December 27, 2011 Nice brachs. They are Derbyia (probably Derbyia crassa). I'm thinking that the limestone block (Paola) tumbled over, and the brachs were originally on its underside (uppermost Chanute Shale). Derbyia can sometimes be found in large numbers near the beginnings of marine transgressions. Context is critical. Link to comment Share on other sites More sharing options...

Kehbe Posted December 27, 2011 Author Share Posted December 27, 2011 Thank you Missourian for the ID and Indy for the confirmation! Indy, the link to Lance Hall's website is fantastic! Lots of good info there and you can bet it will be a site I visit often! I have already added it to my favorites!

Fragile little ones take care of em. TTR, they ARE fragile. As I said in the original post, they are very 'crisp' feeling, (only way I can describe them for lack of a better word) and very lightweight also. They almost feel like glass or porcelain and when you set them down on the table they sound like that too! ( a 'tink' sound) Very unusual composition and very different than what I am used to collecting. Thanks again guys!

Kehbe Posted December 27, 2011 Author Share Posted December 27, 2011 (edited) I went back to this location on my lunch hour today and this is what I found. I really like the Bryozoan fan bits. They are VERY delicate but I managed to lift them with tweezers and get them in a small box without breaking them any further than they already were. They were laying loose, not in matrix. There is some Bryazoa still in the matrix also in these pics but the two pieces are loose, lacy and you can see through them. The off color (white) piece really stood out from all the others and may have found it's way onto the block from another location further up the wall as it does not resemble the other fossils either in texture, composition nor type. I will research further when I get home as well as the small bunch of shells in the lower left corner. All in all, nothing shaped as well as the very first Derbyia found here but some interesting stuff none the less!

Shamalama Posted December 28, 2011 Share Posted December 28, 2011 Too bad so many of the fossils are crushed flat. More victims of sediment de-watering I suppose. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers. When a roadcut presents itself, they tend to lurch and weave. To them, the roadcut is a portal, a fragment of a regional story, a proscenium arch that leads their imaginations into the earth and through the surrounding terrain. - John McPheeIf I'm going to drive safely, I can't do geology. - John McPheeCheck out my Blog for more fossils I've found: http://viewsofthemahantango.blogspot.com/ Link to comment Share on other sites More sharing options...
