Nenando Posted October 14, 2013 Share Posted October 14, 2013 Could this be a brittle starfish of some type? Found in a riverbed north of Denton Texas Link to comment Share on other sites More sharing options...

Nenando Posted October 15, 2013 Author Share Posted October 15, 2013 Awesome thanks you three. This is actually my 1st ever! I was pretty excited. Advice on how to begin to clean it up and possibly expose more of it? Link to comment Share on other sites More sharing options...
Uncle Siphuncle Posted October 15, 2013 Share Posted October 15, 2013 Are you sure it is Duck Creek Fm? Can you name or show the associated fossils to substantiate formation? Based on the quarter for scale, I'd lean toward Stereocidaris hemigranosus or whatever they are calling it now, which I believe has the strongest presence in the Fort Worth, Denton, and Weno Formations, if I'm not mistaken. I've guided 3 people to these things (and not found one myself!) and each time the preservation and matrix were similar to yours, but higher in the Washita sequence than Duck Creek. I think this is a very cool find. 1 Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils." Link to comment Share on other sites More sharing options...
bone2stone Posted October 15, 2013 Share Posted October 15, 2013 Definitely Stereocidaris, or at least what is left of one. And the cigar goes to Dan W. I have only seen one out of the Duck Creek and it was a beaute. Jess B. The best one I've seen was in the Frank Crane collection. Link to comment Share on other sites More sharing options...
Nenando Posted October 16, 2013 Author Share Posted October 16, 2013 Thanks Dan. I was leaning toward Washita but still learning those formations. By the way that's also my first official "cool find" comment lol Link to comment Share on other sites More sharing options...
