Hello to all. This is my collection of flora from the Carboniferous period. This topic will be filled gradually - there is a lot of material. All material originates from the Araukarite Formation of the Gzhel Stage of the Upper Pennsylvania Carboniferous period (303.4 Ma). Unless otherwise specified, it means that the default sample is from this formation. The type of substitution is silicification (sometimes with ferruginization), sometimes with quartz crystals on the surface of the samples. Enjoy watching Part 1. Sample 1. Part of a branch of small diameter with a

From the album: Fossil Amber and Copal: Worldwide Localities
Coleoptera with exuded gas bubbles; these are likely methane, and could be the by-product of methanogenic bacteria inside a xylophagous (wood-eating) species. Some adult members of the Cetoniinae subfamily (family: Scarabaeidae) are xylophagous and known to produce methane; while this is known from Recent species, it's possible such characteristics could be found in extinct members of the Scarabaeidae or Scarabaeoidea (superfamily). This inclusion is contained in the same specimen depicting pholadid crypts. Provenance of specimen is Tanai Township, Myitkyina District, Myanmar. This image was c© Kaegen Lau

Polished specimen containing sediment/calcite-filled domichnia (burrows/crypts) formed by mollusks of the family Pholadidae (likely subfam. Martesiinae): these features were formed while the resin was in a marine environment and after it had sufficiently hardened, all preceding its burial and subsequent diagenesis. Provenance of specimen is Tanai Township, Myitkyina District, Myanmar. This image was captured using a HAYEAR HY-1070 microscope.© Kaegen Lau

Liverwort belonging to the family Lejeuneaceae, contained within the same specimen depicting pholadid domichnia; adjacent to it, is a small root trichome, possibly that of a fern (such trichomes are commonly observed in Myanmar amber, comparable to the presence of stellate "oak" trichomes in Baltic amber).

I recently acquired a small Araucaria cone and I am wondering what the general opinion on cutting/polishing fossil pine cones. Should it be cut to show off the internal structure or is it best to just leave it as a whole specimen? How do you feel about modifying fossils in general to enhance aesthetic, rather than scientific, value? I am interested to hear the Fossil Forum's opinions.

Good evening to all participants! I have accumulated a lot of local (from Ukraine) material - I decided to sort it out, and recurring fossils, or not of interest to me, offers you an exchange. Everything in the photos is one lot. Consists of: 1. Tile from Carboniferous period with fern print; 2. A fragment of the armor of a armored fish Podolaspis Lerichei of the Devonian period; 3. Tile with Silrian brachiopods and tentaculites; 4. Mollusk of Neogene; 5. A small fragment of a fossilized araucaria of the Carboniferous period with quartzite crystals; 6. 2 fragments of orthocer

Araucaria Leaves from Russia?
Zapsalis posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello Fossil Forum, I found a supposed Araucaria fossil leaf from the Russian Federation for a very low price on our favorite site, eBay. The dealer claims that the fossil is an unknown Araucaria species from the Upper Jurassic of Lena River Basin, Markha River, Siberia, Russia. Is this fossil legit and should I buy it?- 1 reply
