L.S., Hopefully the collective knowledge of TFF community will once again prove able to identify something that has stumped me. This time I need your help with these curious stem fragments! A good friend of mine purchased these at a mineral show on the US mainland. The specimens potentially originate from Kane County, Utah, but this provenance is far from bulletproof. It is quite likely, however, that they come from somewhere within the USA. The stems exhibit a hollow centre, with a ribbed internal surface (pith structure?). None of the specimens show nodes or other signs of axial

Found this object on a piece of shale. I suspect it might be a crinoid stem but it's really hard to see very much detail as it's so small. There is a trilobite when I split the piece in half in case that helps, though I'm looking for some more experienced eyes to help me out with id, thanks!

I know how Crinoid columnals looks like, but which are the features of other echinoderm classes (Rhombifera, Diploporita,...)? Image of a crinoid columnal mould (scale bar 5mm).

Received in an opal parcel, i have been told this is a fossil, maybe of a plant stem. If so, i would like to at least put a definite name of some sort on it. Any and all help is appreciated! feel free to ask any questions! Thank you! IMG_2225.MOV

Hi all Im trying to label the morphological parts of a Lepidodendron stem in thin section for my course. I have found a half decent resource online BUT it is unreadable due to the resolution. I was wondering if anyone was confident enough to clear up the labelling lines for me? pic attached. cheers

I have heard that cystoids had stems like crinoids. Is that True? And can u find the stems? Here are some cystoids i found. One of them has like a little hole that looks like a stem would connect. And the other looks like a cystoid with the stem. Not sure if it may be a worm trace. These were found in kinnekulle

.also had this one since i was a kid-at that time I thought it was a tree branch (heh I was only 12 ) but now I would call it a "coral stem"?. the other coral septae/tabulae I have seen/found are always stacked together. Another south St. Louis county find. Any insight appreciated! Bone

During a trip I purchased a container of small marine fossils. I could identify almost all of them except for a few. Age, location, etc. unknown. Does anyone know what they could be? P.S. feel free to ask for more pictures.

Just reassembled, crinoid stem with a bit of character. Probably Poteriocrinus sp., or maybe Rhabdocrinus, 20cm long, 10-12mm diameter, in a high energy deposit full of crinoid, bryozoan and brachiopod débris. It's unusually well articulated for this bed which mostly contains smaller broken bits of stems, arms and plates. There's a probably pathological swelling towards the top, above the radices. Last photo shows it as collected - very fragile and the main stem had largely broken into calcite cleavage fragments. Prepping so far was just a matter of letting it dry,

Good afternoon everybody! During a fieldtrip in Silesia (Poland) last year I visited a rather large spoiltip looking for plant fossils. The spoils left behind by the mining company indicate they still use (or used) the old method to separate the coal from the surrounding debris, allowing the coal to be 'baked' (e. g. the presence of pyrite that turns into sulphuric acid -h2so4- under the influence of wind and rain, ...) something typical for the majority of spoiltips I visited in Western Europe. Unfortunately I have no detailed geological data on the age of the debris i

Hey I was wondering if the stuff next to the crinoid stem is part of the plant and not just smaller stems. All I find are crinoid stems so I was wondering if this was part of the actual crinoid. Found In Cincinnati.

Crinoid Stem The first fossil I found at the park. It was sitting on the bottom of the swimming area in waist-deep, crystal-clear water! Devonian Manhatango Formation Beltzville State Park, Pennsylvania -
I while back I acquired a collection of fossils,minerals, and rocks. They were apparently found at an estate sale before being bought and sold online, hence the prices on the labels (not what I paid for them). It was rather large and confusing, but I managed to figure a lot of it out. One bag, however, has crinoid and blastoid stems and calyxs (calyxi? Calyxese?) and six labels, none attached to the specimens. I was wonder if y'all could help me sort them out, because I'm confused. A few of the labels are just "crinoid stems", is it possible to get a better ID on them? I can take more pictures
