zdufran Posted July 21, 2014 Share Posted July 21, 2014 I did some fossil hunting at the Fort Gibson dam area in Oklahoma this weekend and found some fossils I could identify (blastoids, crinoids, Archimedes bryozoans), as well as some things I can't identify. I would appreciate any help you all can provide. Fossil 1 full view: https://www.flickr.com/photos/zdufran/14682236686/ macro: https://www.flickr.com/photos/zdufran/14518567988/in/photostream/ macro: https://www.flickr.com/photos/zdufran/14518562679/ Fossil 2 full view: https://www.flickr.com/photos/zdufran/14518561460/ full view: https://www.flickr.com/photos/zdufran/14518579018/ macro: https://www.flickr.com/photos/zdufran/14725093313/ Fossil 3 full view: https://www.flickr.com/photos/zdufran/14682213506/ A friend suggested this may be part of an Edrioasteroid, and that seems to fit the bill, but thought I would get some more opinions. Fossil 4 macro: https://www.flickr.com/photos/zdufran/14705084035/ Obviously, there are several fossils here. I'm thinking the prominent item with little pinholes could be a Rhombopora.

FossilDAWG Posted July 21, 2014 Share Posted July 21, 2014 I suspect the "edrioasteroid" is a goniatite-type cephalopod. Apart from the "spiral" structure there is nothing resembling the ambulacral structure or plates of an edrioasteroid. Don Link to comment Share on other sites More sharing options...

Auspex Posted July 21, 2014 Share Posted July 21, 2014 #s 4 & 5 look like bryozoans to me (unless they are a lot bigger that I take them to be). Good photography, bu the way!

zdufran Posted July 21, 2014 Author Share Posted July 21, 2014 Thanks Auspex. I had them both tentatively labeled as bryozoans. I think #4 could be Rhombopora. In my first post in this thread I commented on which of the photos are macro and I kept the same order when I reposted the photos. So yes, many of these items are very small.

TqB Posted July 22, 2014 Share Posted July 22, 2014 Fossil 1 looks like Chaetetes. I think fossil 2 might just be a septarian nodule. Tarquin Link to comment Share on other sites More sharing options...
zdufran Posted July 22, 2014 Author Share Posted July 22, 2014 Thanks for your help, TqB. I have looked at some Chaetetes photos, per your suggestion. I'm not sure if that's what I have or not. The fine scale details look different when I compare to the macro photos of my fossil. Zach New to fossils, but not to nature Link to comment Share on other sites More sharing options...
