Dear buyers,I warmly welcome in my “ Paleobotanica” store created especially for the enthusiast of Palaeobotany!I am a fossil plants collector from many years, and unlike other some sellers on Ebay I do not guess the names of the plants, and don’t sold common plants with names of rarer species. Each bought specimen will be send with attached copy of the scientific literature from which your specimen was described – with the characteristics of the selected plants by which I could classify Your plant into genus and species. This will allow you to make sure that the bought specimen is really what was written in the item description. I also ask, to give me questions about any carboniferous age specimens. I will be very happy to help You in the determination of your findings. For me this is a real pleasure! Specimen: Very beautiful - Sphenophyllum cuneifolium ( Sternberg) Zeiller Locality: Poland, GZW Upper Silesia Coal Basin, Stratigraphy: Westphalian B - Porebskie Beds Age: ca 305 Mya matrix dimensions: 10 ,0 x 11,5 x 1,5 cm Description: Sphenophyllum , genus of extinct plants that lived from the end of the Devonian Period to the beginning of the Triassic Period (about 360 to 251 million years ago); it is most commonly reconstructed as a shrub or a creeping vine. Sphenophyllum had a strong node-internode architecture, which has led some authorities to ally it with modern horsetails. Branches and leaves were arranged in whorls at each node much like the later Calamites ; however, the leaves of Sphenophyllum were triangular in shape. Spore-bearing cones were also similar to those of Calamites and modern horsetails; however, Sphenophyllum lacked the hollow central stem that characterizes horsetail relatives because its tracheids, or water-conducting cells, were arranged in a central triangle surrounded by wood. Sphenophyllum grew in floodplain swamps, away from the margins of rivers.
