  1. 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
  2. Hi All we have had on the forum some quite out there post in the last few days so I thought I would add a post that is a little more grounded . I know very little about Scale Trees and some may think they are a little dull but to me they are quite striking. The Carboniferous was the heyday for early land plants. Giant lycopods, ferns, and horsetails formed the backbone of the land’s ecosystems. One of the most abundant plants during these times was the lycopsids known as the scale trees. Scale trees collectively make up the extinct genus Lepidodendron order Lepidodendrales. The name “scale tree” stems from the fossilized remains of their bark and roots, which resembles and can be at times mistaken for reptile/dinosaur skin . In fact it resembles more scaly skin than it does anything botanical. I am starting my post with a favourite Lepidodendron specimen give to me last Christmas by Doren. I will show my entire allotment in the coming days. Thanks for looking and I look forward to seeing your specimens and learning more about this subject . Cheers Bobby
  3. Stigmaria

    From the album Plants of the Lewellyn Formation

    Root of a Lepidodendron (scale tree) with rootlets radiating out at right angles along both sides. The white powder highlighting the imprint is iron oxide, most likely pyrophyllite, left over from the actual plant. Lewellyn Formation (same formation that runs through St. Claire) Lackawanna County, PA Pennsylvanian age
  4. Many roots of the Lepidodendron have been found here cast in fine grained, very hard sandstone. One specimen of bark has been found that is in a repetitive diamond pattern reminiscent of scales on a tropical palm type tree. Another one off specimen is of the interior trunk or wood of the tree--(presumably). All of these specimens are the same type of sandstone. This is definitely Lepidodendron country as no other fossils have been found here to date. Pics of individual specimens will be gladly posted upon request.
  5. Can anyone ID this fossil please?

    Hi, I really don't know too much about fossils but I found this on my farm in Co. Laois, Ireland. It was in a wooded area and my farm is about 100 metres above sea level. Thinking it could be a lepidodendron from googling things, however I'm really not sure. Attached are pics of the fossil. Thank you in advance!
  6. Plant Hash Plate

    From the album Plants of the Lewellyn Formation

    1) Shrub/vining plant - Spenophyllum majus 2) unidentified seed fern 3) Neuropteris sp. 4) Scale tree- Lepidodendron sp. 5) Seed Fern- Alethopteris sp. 6) Seed Fern- Neuropteris? 7) Shrub/vining plant- Sphenophyllum sp. McIntyre Mt., Ralston, PA Pottstown member, Lewellyn Fm. Carboniferous
  7. Stigmaria, lepidodendron or rock

    Found this in a washed out ditch. I have someone suggest that this might be a stigmaria, lepidodendron species. Would like to confirm ID. Thanks
  8. Alabama coal mine additions

    I picked up two additional fossils I needed. First one is a Calamites Leaf Tip, needed this to go with all my other Calamite fossils. Second is a Lepidodendron Leaf , I only had one small sample of this so wanted more. this is all Pennsylvanian age
  9. I am looking for confirmation on my IDs of these plant fossils, especially what I think is form genus Lepidophyllum. Buck Mountain No. 5 coal mine, Llewellyn Formation, Upper Pennsylvanian, Pennsylvania, USA. Scale in cm / mm. Lepidodendron sp. Lepidophyllum?
  10. Hello, I have two strange objects that my wife and I found in Pittsburgh in Carboniferous territory. The triangular shape one is a little larger that a quarter while the spherical rock is about the size of a baseball. I haven't seen anything like these two rocks in any of my fossil trips, so any help would be terrific. Thanks everyone!
  11. Carboniferous Plant Fossil ID

    Carboniferous Period experts! I need some help getting the correct ID on this fossil. I was finally able to get out to do some Carboniferous Plant fossil hunting on Monday after 2 months! I find a lot of these and wonder if they part of the same plant? The branch to the right that has a coal film on it seems to be that of Lepidodendron and in the upper left what appears to be Lycopodiates? I've associated the Lycopodiates as a ground plant? Is what up in the upper right the leaves of the Lepidodendron or the ground plant I spoke of earlier?
  12. Lepidodendron

    From the album Cory's Lane, Rhode Island Fossils

    Lepidodendron bark - Found in 2019 at Cory's Lane fossil locality, Rhode Island.
  13. Hello, this specimen is from an excursion in search of permineralized material in the upper formations of the lower Pennsylvanian Gobbler formation. In this particular formation I have found Psaronius and various Lycopsids, calamites&piths, etc. This is fairly weathered specimen in quartz sandstone, but the diamond pattern does not seem typical of Lepidodendron. Each 'diamond' seems more like a square. There appear to be 2 separate layers of diamond shaped material so these might be smaller branches toward the crown of a Lycopsid. The upper one is more complete in appearance. The lower one seems to have an additional overlay of material. Dimension of the upper one is 25 mm wide and 125mm long approx. Suggestions are most welcome.
  14. Lepidodendron (?) Bark

    I found this in Bochum-Weitmar, should be carboniferous. Is it a lepidodendron? Greetings!
  15. Lepidodendron oculus felis

    I was give these two pieces by a frirend who cliamed they are both from the same Shanxi formation ( lower permian, like missisippi in US) in Yangquan, a well known coal mine in North China. He said they are just two pierces of the same thing ( Lepidodendron oculus felis). I found it hard to swallow, as the two pieces look rather different. however after some digging into literrature, it seems he is backed by many old scholars (not all, though) including Kawasaki, Stockmans and Mathieu. The last two pics I got from an old book, which look rather similar to mine, are considered by these researchers as belonging to the same species, although they are rather far between in loacation and age ( from upper carbon to upper permian). please enlighten me.

    Lepidodendron Fossil SITE LOCATION: Eastern Kentucky TIME PERIOD: Carboniferous, Pennsylvanian Period (307-331 Million Yeas Ago) Lepidodendron — also known as scale tree — is an extinct genus of primitive, vascular, arborescent (tree-like) plant related to the lycopsids (club mosses). They were part of the coal forest flora. They sometimes reached heights of over 30 metres (100 ft), and the trunks were often over 1 m (3.3 ft) in diameter. They thrived during the Carboniferous Period (about 359.2 ± 2.5 Mya (million years ago) to about 299.0 ± 0.8 Mya) before going extinct. Sometimes erroneously called "giant club mosses", they were actually more closely related to today's quillworts than to modern club mosses. The name Lepidodendron comes from the Greek lepido, scale, and dendron, tree. By the Mesozoic era, the giant lycopsids had died out and were replaced by conifers as well as smaller Quillworts. This may have been the result of competition from the emerging woody gymnosperms. Lepidodendron is one of the more common plant fossils found in Pennsylvanian (Late Carboniferous) age rocks. They are closely related to other extinct Lycopsid genera, Sigillaria and Lepidendropsis.
