Unidentified petrified plant stems from US
paleoflor posted a topic in Fossil IDL.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
Stem shaped object
Alexthefossilfinder posted a topic in Fossil IDFound 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!
Gabby Collins posted a topic in Fossil IDFound in the French River. Possible Crinoid?
Features of non-crinoid columnals?
mbarco posted a topic in Questions & AnswersI 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).
nala posted a topic in Fossil IDfirst time i see these "spines" on the side of a stem,Lepidodendron or Sigilaria? full of cyperites on the other side,an idea?

Help with Lepidodendron stem morphology
da_capo posted a topic in Questions & AnswersHi all Im trying to label the morphological parts of a Lepidodendron stem in thin section for my course.

Stems on cystoids?
Jurassicz1 posted a topic in Fossil IDI 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
Fossil coral septae?
Bonehunter posted a topic in Fossil ID.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

Unknown marine fossils

20cm crinoid stem with radices, Carboniferous, UK
TqB posted a topic in Member CollectionsJust 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,
Textured stem, ichnofossil or something else?
ziepe posted a topic in Fossil IDGood 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
keldeo072 posted a topic in Fossil IDHey 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.
Your best guess at these please!

Blastoid and crinoid mix up
WhodamanHD posted a topic in Fossil IDI 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
