  1. spores on leave?

    a friend of mine found this in a Pennsylvanian shale near baijing. The leave, of which the width is about 1cm(which could serve as a scale) is not well preserved and possibly of cordaites, which is very common there. We've never seen the grains like this before, of which a wild guess is some aqua-plant's spores. They are not pits as may be taken looking at the second pic. any ideas?
  2. I'm piling back in late from a fossil hunt and wanted to get this online. Found in a lower Pennsylvanian formation locally. Typically find cordaites and ferns in this formation. Today, this odd split pair caught my attention. For size reference the small calamite next to the split pair is a little over 5 cm long and 2 cm wide. Although not a great field shot I'm posting it up now in case someone can point me in a solid research direction. Part of me thinks cordaite but the unusual branching features on one side only are quite odd to me. Perhaps some sort of rhizomic structure? I will post a close-up tomorrow when I have access to natural light again. Thanks for any advice or suggestions, Kato
  3. I decided to get out for what might have been the last warm day in the 70's (Farenheit) for a walkabout to explore high country access and exit points for some long climbs I would like to do this winter. For this trip I rucked primarily in the lower Pennsylvanian formations looking specifically for a new occurrence of mineral rich shale formations similar to one I had found last year that yielded plant fossils. I did manage to find a small but new-to-me location that was very geologically complex having anomalies in the midst of the shale/sandstone formations. First this Cordaite about 5" tall (12.5 mm) Quite near were numerous Liesegang specimens. This one about 2" x 2" (5mm x 5mm) There seemed to be at least two small areas where hot gasses may have vented through the field leaving small seams of quartz-like material. In one location samples present as Bornite. The largest piece below is 3" x 6" (7.5mm x 15.5mm) The other area was just at the contact zone between the shale having plant fossils and sandstone having plant fossils. This specimen seems to have mostly converted the sandstone and permineralized material into quartz. There is a small specimen of permineralized material left in the lower right corner. Also, there is some mineralization which I believe is mostly iron. As this new location is about 4.5 miles from where I parked my vehicle I did not collect many specimens (small pack) but plan to go back and spend more time searching.
  4. L.S., To liberate storage space, I would like to offer the following plant fossils for trade. All specimens below come from the Late Carboniferous of the Piesberg quarry near Osnabrück (Germany). Scale on photographs in centimetres (1 inch = 2.54 cm). Specimens B, C, F and G show neuropterid fronds of various sizes (most likely Laveineopteris rarinervis). Note specimens B and G were recovered broken and have been glued/repaired. Specimen E is a large plate and shows reproductive structures of Calamites (E-1), a Laveineopteris frond (E-2), a strap-like Cordaites leaf, and some Annularia-like leaf whorls. If interested, I could also offer the counterpart of E. If preferable, I can cut specimen F to size (currently large slab of rock for the actual imprint). In general, please note that these specimens are rather large and heavy (I will cover the shipping costs, but you will need space to display these pieces). In return, I would be mainly interested in plant fossils from the Devonian to Cretaceous (but feel free to offer younger material also). Kind regards, Tim Specimen B: Specimen C: Specimen E: Specimen F: Specimen G:
  5. Cordaites

    From the album Carboniferous Plant Fossils in My Collection

    Cordaites were very large leaves that resembled corn leaves, with parallel grooves running the length of the leaf.

  6. On a short schedule for searching so it was a mad dash. I have very few ways to easily reach the Pennsylvanian Formations. Ordovician-Silurian-Devonian-Mississippian no problem. Anyway, I've found some interesting ferns in the Pennsylvanian Gobbler and wanted to see what I could find in another location about 3 miles as the crow flies away. About 1.5 miles into the site and a fairly productive morning for an initial search. Not the best of specimens but holds promise. Found this interesting brachiopod panel presenting itself with some glints. It was easily opened up by dragging my long chisel into it Some of the brachs. Not cleaned up yet.. A brach hash plate and the layer the brachs deposited on showing trace fossil depressions. Not cleaned yet A couple of phylloid algal limestone specimens
  7. Here is a sample of a fern and Cordaites along the bottom (my guess) I've been finding. Pennsylvanian formation in an area with igneous intrusions. I would enjoy being able to identify and label different fern types in the future so any help naming these now and a good source for learning more would be my ideal goal. Lastly; what induces the coloration? Is it some form of pyritization? High iron mineral content of water and ground it grew in at the time? I have additional specimen photos that appear to be of other types but I just realized my file sizes are limiting how many I can post at a time...need to learn how to do better in future posts.

  12. I've been searching for some carboniferous wood/bark examples and think I've finally found a number of them. These are found loose in some mine spoil piles along with some coal chunks in the Braidwood Biota areas. I'm not sure if these are cordaite, psaronius or seed fern. Any ideas? ITEM 1: Here are four pictures of the first item. The last picture shows a really zoomed in area that shows individual xylems I presume.
  13. St. Clair Trip Nan and I took a trip to Deer Lake and we managed to squeeze in a couple of hours at the end of the day to visit the St. Clair fern site - which we consider to be our "home site." We always see animals there - a bear and cub were there last year, an 8 foot long black snake (it was really that long!) and this time we saw a dozen male and female turkeys. The site has been pretty well picked over by a season of fossil hunting so there aren't as many good finds lying scattered around on the ground but we don't normally scavenge these shards anyway - we either excavate the open pits left by previous fossil hunters, or we find promising looking pieces that have been discarded and crack them open with chisels. We also have gained a good sense of what kinds of fossils are located in various places on the site and we visualize in our mind's eye what this Carboniferous site must have looked like, 308 million years ago. This is Nan showing the width of a giant Calamites tree trunk that has been eroding slowly out of the ground substrate. The tree was squashed flat and people walking over it have begun to destroy and flake off what was previously a perfect large tree trunk embedded in the ground. I always say that cracking open fossil rocks is like opening a box of crackerjack. Here's a great example of a crackerjack fossil: Opening a Crackerjack Fossil This fossil looked very ordinary and not at all promising. However, it was thick and easy to crack open so I gave it a whack with my hammer and chisel. The results unfolded exactly as you see here - revealing a nice section of Cordaites (a very large leaf with close-together grooves, that looked like a corn leaf) and other fern leaves. We looked for a display piece for a colleague and Nan found this nice specimen: This will look nice in our friend's office, placed on a tilted rack we bought from Michael's craft store: We also found this sphenophyllum (a small plant that grew like a vine in the coal swamps):

  15. Show Us Your Cordaites

    Has anyone here collected these Pennsylvanian plants? If so, show 'em. This gymnosperm tree is classified under a handful of genera: Cordaites - leaves Cordaianthus - seed cone Cardiocarpus - seed Artisia - stem Amyelon - roots I'll start with a few I've posted on the forum already.... Leaf bundle (Cordaites): Leaf (Cordaites): Stump and roots: Roots (Amyelon?): Roots (Amyelon?): All are from the Pennsylvanian Winterset Limestone of the Kansas City area. A reconstruction of the living tree:
  16. Cordaites

    I know these aren't rare or unusual but this is a really nice example of Cordaites from the Pennsylvanian. Just thought you would enjoy looking at it! pic1 pic2 (edit) Added Pic2 Just a close up pic and this website I thought was an interesting site concerning cordaites http://www.uni-muenster.de/GeoPalaeontologie/Palaeo/Palbot/seite18.html
