-Andy- Posted April 6, 2013 Share Posted April 6, 2013 An unidentified one traded to me by an awesome collector. Probably agathiceras. Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday! Link to comment Share on other sites More sharing options...

Al Dente Posted April 9, 2013 Share Posted April 9, 2013 Here are some I collected a long time ago. I can't find the publication that has the site information but it is the Caney Shale from Oklahoma. I believe it is Mississippian. This first photo shows two goniatites, the one on the lower right has the shell replaced with calcite and you might be able to see the original sculpturing on the shell. The diameter of the top one is 43 mm. Here's a side view: This is a small one with several constrictions. No idea on the species. it is 14 mm diameter. And this one is very small about 6 mm. diameter, you can see the protoconch in the middle: Link to comment Share on other sites More sharing options...

Those are great! I didn't know the Caney had much of anything in it, I need to visit the outcrops I know of again and look harder. What part of the state did you find those?

Missourian Posted April 9, 2013 Author Share Posted April 9, 2013 Here are some pubs on the Caney Shale of Oklahoma: http://www.amazon.com/The-fauna-Caney-shale-Oklahoma/dp/B0006FESOI (1909) http://www.jstor.org/discover/10.2307/1301116?uid=3739672&uid=2129&uid=2&uid=70&uid=4&uid=3739256&sid=21101880222473 (1962) Context is critical.

I didn't know the Caney had much of anything in it, I need to visit the outcrops I know of again and look harder. What part of the state did you find those? These are in large concretions that occur in the shale. Your best bet is to find a creek that cuts through the shale and search the creek bed for these large concretions. The ones in the Caney can be a few pounds to several hundred pounds. Link to comment Share on other sites More sharing options...
