Guest solius symbiosus Posted May 13, 2008 Share Posted May 13, 2008 I was back at the site just before dark yesterday, and I was able to remove a small section of bed. I retrieve a section about 10 cm by 30 cm in several pieces. When I put a little soap and water to it, I found 2 more crinoids. As this site is a roadcut, I can't do any serious quarrying, but I can probably free a few more pieces without too much work. If the bed were a little closer to the top of the outcrop, I would attempt to remove some overburden. As it is, there would be about a 1/2 meter to the top, and then the hill starts. So it would be a lot of work, and it is state property. The outcrop As you can see, they are well entrenched in matrix. I'll post some pics when the prep is done(whenever that might be).

ashcraft Posted May 13, 2008 Share Posted May 13, 2008 That matrix looks pretty hard, how are you prepping them? Blasting? Brent Ashcraft ashcraft, brent allen Link to comment Share on other sites More sharing options...
Uncle Siphuncle Posted May 13, 2008 Share Posted May 13, 2008 Have you tried KOH on associated stems yet? I can't overemphasize the dramatic effect this stuff has on echinoids, but again its efficacy varies with lithologic composition and character. Grüße, Daniel A.

Guest solius symbiosus Posted May 13, 2008 Share Posted May 13, 2008 Yeah, the matrix is hard. I haven't picked up any KOH yet, but I will this week. What little prep I have done is with a pen vice. I haven't built a cabinet for the blaster. EDIT: I was looking at this poop eater(Cyclonema varicosum), flipped it over, and found another one. I have found C. varicosum attached to the anal tube of crinoids in the past. Link to comment Share on other sites More sharing options...
Guest solius symbiosus Posted August 30, 2008 Share Posted August 30, 2008 I didn't want to start a new thread for just a couple of things, so I'll bump this one, and put them in here. I went out to the outcrop that has been producing the Pychnos(first time out since returning from the NY trip), but this time I moved a few hundred meters down and a couple of meters up in the strata(I can't climb up to the crinoids with my leg the way it is). I saw a lot of the usual stuff, but a couple of things were decent enough to bring home. a nice bivalve Byssonychia sp. length from beak to margin about 4cm another unknown bivalve with original material x10 x20 I haven't figured out what this is, but it is encrusted with cornulites and bryozoans. I was think sponge, but it is not solid. It is like a sphere with the center filled with matrix. I also brought home a chunk that is polluted with micros... Hyolithes, proto-gastropods, ostracodes, and even a micro bivalve. Link to comment Share on other sites More sharing options...
Auspex Posted August 30, 2008 Share Posted August 30, 2008 Jolly good! Looks like the fossils are willing to meet you half way.

Guest solius symbiosus Posted August 30, 2008 Share Posted August 30, 2008 They probably more came to me as I sat at the bottom of the talus pile, and worked my way down the outcrop. Link to comment Share on other sites More sharing options...
