found this piece in a CP(early P or late C) stratum west of beijing, China, in which the most common stuff is neuropteris ovata. The vein is obvously neuropteris type, as can be seen easly under the sun, if not in the pic. The stem is about 5mm wide, which can be used as the scale. I have never seen neuropteris with this shape and size.

found in Beijing, late Carboniferous or early permian among Cordaites, Calamites, Neurooteris ovata, sphenophyllum, etc., pretty common. Calamostachys (Paleostachys) or bowmanites or something else?

It is in Yangquan, Shanxi province, which is a known for its CP coal mine ( the best in China) and fossils. This is the well known Taiyuan Formation (late philadelphian, late C early P) . Tons of marine stuff, you have to literally walk on the crinoids and brachiopods calcite, yet a few dozen meters away you see the land plant fossils like cordaits. I saw crinoid stem pieces in all shaps, round rings, roud rings with radiant rays, eclips rings, penta rings, and square and rectangle pieces ( one in the foto), as well as internal molds. They are every where scattered. I have little knowledge about it. I wonder if I could get any help here, like possible ID, or if there is any on-line place to learn. I only have some generic paleotology book and a small chapter on crinoids fossils, and only a few sketchy words for crinoid stem in CP period.
