My Carboniferous collection

[Svetlana]

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.

Sample 3. Stem of small diameter.

Sample 4. Stem of small diameter.

Sample 5. Small-diameter stem with whorled knots.

Sample 6. Stem of small diameter.

Sample 7. Stem of small diameter.

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.

Sample 9. Stem of small diameter, broken lengthwise..

Sample 11.  Stem of small diameter with quartz-crystalls.

Sample 12.  Branch with quartz-crystalls.

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?

Hello Tim.
Thanks for participating.
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.

13. Half tree trunk with excellent knot.

[Svetlana]

14. Poorly preserved branch, but visible internal structure and whorled knots.

[Svetlana]

15. A branch that burst along - but quartz crystals inside opened

[Svetlana]

16. Half of the stem. Interesting preservation

[Svetlana]

17. Branch with whorled knots

[Svetlana]

18. This stem is darker and more ferruginous - but the quartz crystals on the surface give it a charm

[Svetlana]

19. The same stem as the previous one

[Svetlana]

20. Small stem
