Svetlana Posted December 12, 2021 Share Posted December 12, 2021 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 whorled arrangement of knots. VID_20211212_143605.mp4 Link to post Share on other sites

Svetlana Posted December 12, 2021 Author Share Posted December 12, 2021 Sample 8. Stem of small diameter. This trunk (kalamite?), although broken lengthwise, is no less valuable than the others. The whorled arrangement of knots and a barrel-shaped core are clearly visible (I will exhibit such cores later); besides, the preservation is very good.

paleoflor Posted December 13, 2021 Share Posted December 13, 2021 Cool specimens, thanks for sharing! Some of them appear to have preserved some internal (anatomical) structure. Did you ever try to cut and polish specimens? Link to post Share on other sites

You're right, some of the samples retain their cellular structure and look very attractive. I know of the finds of Kalamite from this place, and its slabs were just superb.
