pleecan Posted January 6, 2012 Share Posted January 6, 2012 Very nice specimens! Thanks for posting! Link to comment Share on other sites More sharing options...
glacialerratic Posted January 6, 2012 Share Posted January 6, 2012 Wow! Excellent collection. I've done my share of Mazon Creek collecting, and have seen papers on the nodules of MO/KS/OK, but have only seen a few of the fossils themselves, and mostly here on TFF. Thanks for sharing (I'd love to see more)! Link to comment Share on other sites More sharing options...
Shamalama Posted January 6, 2012 Share Posted January 6, 2012 I had no idea that the Eurypterids ranged up into the Pennsylvanian. Very cool fossils! -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...

Roz Posted January 6, 2012 Share Posted January 6, 2012 You have been holding out, Missourian.. Those are fantastic! I have always found those very intriguing.. I am not sure if any have been found in Texas.. So that's upper Pennsylvanian? Welcome to the forum! Link to comment Share on other sites More sharing options...
grokfish Posted January 6, 2012 Share Posted January 6, 2012 (edited) Ok missourian...every post of yours is something I look forward to! Awesome! Those are great candidates for FOTM!!! Edited January 6, 2012 by grokfish Link to comment Share on other sites More sharing options...
Missourian Posted January 6, 2012 Author Share Posted January 6, 2012 Thanks all for the comments. I didn't find them myself, but I was able to obtain many nodules soon after the site was discovered. Eurypterids can be found throughout the Pennsylvanian. For some reason, these fossil-bearing siderite concretions tend to be limited to the mid-Penn Demoinesian. As eurypterids are mostly non-marine, I figure that any plant-bearing deposit has the potential of producing one or more (though they would be frustratingly rare). Context is critical.

fossilexpress Posted March 23, 2022 Share Posted March 23, 2022 First I have heard of eurypterids from Missouri (saw one for sale on online). What is the current status of these specimens? Are they in or headed to a museum? Link to comment Share on other sites More sharing options...
