gturner333 Posted November 14, 2015 Share Posted November 14, 2015 In bulk sampling a Pennsylvanian site in Jacksboro, Texas, I constantly run across these tiny, glass-looking tubes. I think they may be geological, but would love to know more about them. I have attached a picture of some that are individual and a picture of one in situ. I also see them in hash plates from this area. Any ideas? Thanks. Link to comment Share on other sites More sharing options...
Auspex Posted November 14, 2015 Share Posted November 14, 2015 Any spiny brachiopods in that formation?

BobWill Posted November 15, 2015 Share Posted November 15, 2015 Several, like Juresania nebrascensis, Echinaria semipunctata and Antiquatonia coloradoensis. Link to comment Share on other sites More sharing options...
gturner333 Posted November 15, 2015 Author Share Posted November 15, 2015 Interesting thought, Auspex. I know of the Juresania sp., but not sure how long their spines were. There may be others, but I am not familiar with them. Anyone have a thought on this? Link to comment Share on other sites More sharing options...

ZiggieCie Posted November 15, 2015 Share Posted November 15, 2015 (edited) Here are a few of my Productid Brachiopods from the Meadville shale, Cuyahoga Co, Ohio The spines are hard to come across attached but I have some. I believe these are a Juresania sp. But cannot find exact one for my local. Below the 3 1/2 measurement are some spines between the two Brachs.
