Hi everyone, I've been working on a project about fossilised megaspores found in a Namurian (Late Carboniferous) coal seam in the UK. There are very few papers and photographs of megaspores so classification is a challenge! I have a couple of my unidentified specimens here that have been extracted from the coal, and was wondering if anyone could help me out? Light microscope images are attatched. The maximum diameter of the compressed spore is 1125 µm for Species A, and 1225 µm for Species B. I believe that the depositional environment was a Late Carbonifer

Hello dear forum members, among the collection of my late uncle there was a box of coal fossils, most of which are flat crumbly pieces of plant material. I left most of these in their protective wrappings for now. among the fragments on the bottom of the box I found some nodules, I think these caught my uncles eye and where collected on the same trip as the plant fossils. (from Germany, hard coal, not lignite, thats all I know). The nodules are heavy like ore minerals (pyrite comes to mind) There is one with an interesting texture. Maybe a coprolite?? @GeschWhat?

Upper Carboniferous (Duckmantian) Fish/shark tooth from coal measures. N. Wales.
Skatetom posted a topic in Fossil ID
Hi people! I'm a PhD student studying a Duckmantian fossil forest in North Wales. I have found these phosphatic fish/shark? teeth and scales I need an ID on. I suspect they are Adamantina Foliacea (Cuny and Stemmerik 2018) but that is a marine shark and this sequence is almost certainly completely freshwater and thought to be an upland swamp. I'm currently doing isotope work on the nodules and plant fossils and that appears to be confirming this is a completely freshwater system. Anyone have any ideas? You'll have to click on the images again once you've opened them to- 6 replies

Roughly 200g of small (≈1g) nodules and runs of amber from the West Open Pit Mine in Fushun, China; the mine was closed in 2019, but small pieces of amber are still recovered from coal found in the gangue piles; it is separated from the matrix by mechanical action and immersion in large vats of saltwater solution, and recovered with netting as it collects at the surface. This material is hard, takes a high polish, and is often shaped and drilled to make beads. Its chemical and spectrographic signatures indicate this amber is derived from a cupressaceous source.© Kaegen Lau

Hi all, So I found this odd piece of petrified wood on Marrowstone Island in Washington state. I find petrified wood often on the beach here. This one has a dark band running through the specimen. The dark band is coal like except it has wood grain banding in it as well. The band is brittle and I broke off a few chunks and tried to burn them, and they do quite like charcoal. Now I also managed to get a small piece of the petrified wood to come off and it did not burn. I am positive the wood is petrified too, I have many samples of it I have found including one weighing over 60lbs.

Sumatra Blue Amber (Sinamar Fm., ~30 Ma)

4.3g dark, transparent blue amber from West Sumatra. After grinding and polishing, I was surprised to discover that it contains 2 ants and 2 winged ants (possibly wasps); these were a little tricky to photograph, due to the amber's strong fluorescence under 140 lumen LED light, so these inclusions had to be backlit. I used a Canon EOS 500D, Canon 60mm f/2.8 Macro Lens, and combined 2x and 4x Hoya circular magnifier lenses (8x).© Kaegen Lau

Are these "black rocks" fossils, pumice, slag? I'm so confused
natwell19 posted a topic in Fossil ID
hello all, I found a lot of this specific type of rock and I thought they could be fossils. Now I'm not so sure. They have what appears to have a spongy inside and flat outside, on the sides that are still there. I tried to take pictures to show them well. A few of the pieces have two "lobes" at one end and the lobes appear to be splitting. They are all the same color, though some are dry and some are damp still. I was trying to figure this out on my own, and I thought it could possibly be coal (if not a fossil), but i really don't know how to test it. My husband did try to light i -
I found this in St. Clair county, Alabama. The area is near strip mines, so this may have come from tailings. I think it was uncovered when I dug a pool several years ago, but just recently found it. Thanks for any help!

Pennsylvanian (Llewellyn Formation, 308-300 MYA) plant fossils from coal mine tailings near Mt. Carmel, PA.
fossilcrazee posted a topic in Fossil Hunting Trips
This was, essentially, a quick scouting trip based on threads on the Forum. Don't know much about these fossils but wanted to confirm the location and density of Pennsylvanian (Llewellyn Formation, 308-300 MYA) plant fossils from coal mine tailings near Mt. Carmel, PA. (NOT St. Claire, which is closed to collectors). There were abundant specimens, many bearing evidence of pyrite replacement: orange stems and plant hash. There was also some evidence of pyrite replacement by pyrophyllite to yield silver-colored films. Against the black matrix, the silver-film plant fossils are beautiful and,- 7 replies

I am quite sure this is a tree/gymnosperm Is it a lepidodendron. It was found in the screameston coal member carboniferous, Northumberland England.

I visited a coal mine last weekend with a group, and we had a good time finding Carboniferous era fossils. There were large volumes of plant fossils. I did find a few marine fossils (brachiopods) also. I found the "thing" below as well, which mystified me. I found it splitting a rock, and there was a counterpart as well. I did not retain the counterpart, perhaps I should have (it was broken). Formation: Pottsville Group Age: Pennsylvanian Period, Westphalian-A (312 million years old) .Jefferson County, AL Anyone know what this might be?
