Rockaholic Posted March 19, 2017 Share Posted March 19, 2017 These are Carboniferous fossils preserved within sideritic concretions found near Terre Haute Indiana.They were collected from the Busseron Sandstone Member of the Shelburn Formation, in shales above the coal seam Coal (No. 7) and are dated from the Middle Pennsylvanian, which correlates with the Westphalian D. Macroneuroptis are common at the location that I collect but this is the first Trifolate Macroneuropteris that I've found.When it first split only one of the ovoid shaped basal pinnules was exposed. A tap of the hammer exposed the second basal pinnule and I secured it with a little glue. Unfortunately the apex of this leaf is missing but I was still happy to have found it.

Rockaholic Posted March 19, 2017 Author Share Posted March 19, 2017 Sphenopteris is uncommon at the sight that I collect but this one split recently so I thought I’d share this photo also. Link to comment Share on other sites More sharing options...

deutscheben Posted March 23, 2017 Share Posted March 23, 2017 Very nice plants, love that first one. I have collected in the Shelburn but have yet to find a single Macroneuropteris- I will just have to keep searching! Link to comment Share on other sites More sharing options...
