The tree fern genus Tempskya, known from worldwide Cretaceous deposits, was first reported from a North Carolina site in the February 1970 issue of the Lapidary Journal (article reprinted in February 1977 issue). A follow-up article on additional finds appeared in the January 1978 Lapidary Journal. The collecting site is now inaccessible and overgrown. Cut and polished trunk slabs show multiple roughly oval-shaped structures that are stems, surrounded by a mass of tiny roughly circular structures that are roots. Stems often have knobby projections that are budding leaf petioles, and free leaf petioles can appear in single or multiple horseshoe-shaped structures as the grow towards the trunk's surface. Photos show a collection of 31 of 40+ North Carolina slab specimens.

I was rooting around in Ambridge, Pennsylvania, Beaver County yesterday and found some interesting plant fossils. They are Pennsylvanian and out of the Glenshaw Formation. Not sure if they're identifiable or if I would need a microscope to ID. Any help is appreciated.

look at this fossil full of crinoid stem pieces I found today
matthew textor posted a topic in Fossil Hunting Trips
Hi this is matt again today in the creek I found this rock with a lot of crinoid stem pieces all over it here are some photos -
All of these came from Alluvial gravels in creek close to Trinity river. Only one I'm confident about is first one, obviously coral, but is it recent and should it have been here? It feels and clinks like glass. Next one I'm not sure if it's geological or not, seems to have well defined tubes of some sort. Next one lacks detail, plant, borrows,coral? Last one I thought was shell but looking at the rest of it not so sure, looks like it had a center with the tubes surrounding it, coral? rugose? Oh and second one is same size as last one.

So why are crinoid stem fossils so...full of stems?
FossilizedJello posted a topic in General Fossil Discussion
Hey everyone, just wanted to start a mini discussion about this. I just find it weird that there are tons of fossil clusters consisting of just stems. Then occasionally you see a full crinoid fossil with the stem and crinoid itself. So my point is that usually you see a cluster of stems or just one crinoid with a single stem. How come these clusters with tons and tons of stems dont contain the organisms and just the stems? The obvious answer would be difficulty in fossilizing. But it just doesnt make sense as you would think you would see more in these stem clusters. -
Reccomendations on Carboniferous Localities in E. PA, WV, and KY
JK Marquis posted a topic in Fossil Hunting Trips
I'm going to be taking a drive this year from Pittsburgh to Charlottesville to SE Kentucky, to Knoxville, TN to catch some of the autumn foliage, and was wondering if anyone had any suggestion on fossilized foliage outcrops or spoils piles. I'm trying to focus on ferns and other plants, as I've collected a lot of marine fossils previously and want to get some new types of specimens. I've seen some stuff online about Ambridge, PA and Big Hill in KY, but haven't been able to find too many other public spots besides that. Just wondering if anyone had any suggestions or recommendations. Thanks.-

I finished prepping the lot of crinoid stems recently. It took quite a while to complete as I was using only an engraver, picks and brushes. I was told later that I could have soaked it in vinegar to remove most of the matrix. Is that true?

I attended an estate sale last week and the homeowner collected rocks. Sifting through the 50-cent box, I came across this specimen. It's not a complete crinoid, but the size -- and the size variety -- of the stems was particularly enticing. I haven't a clue about where she may have collected it, but the coral, brachiopods and bryozoan fossils in the box look like those I've collected in Michigan.
