My Carboniferous collection

[Svetlana]

21. This "scar" on the surface of the calamite would have been discussed in another thread - it is also from this place

[Svetlana]

22. One more branch

[Svetlana]

23. Small broken branch

[Svetlana]

24. A fragment of a stem with a knot; the core is visible inside

[Svetlana]

25. Small branch

[Svetlana]

Some of the cores of various plants found in one place. Some are flat, some are barrel-shaped.

[Svetlana]

The name "artisia" is hardly applicable to them - after all, this is not a cast of the emptiness of a plant; it is the core itself, which has preserved the cellular structure. In this photo (the photo is not mine; I took it from the Internet), the same samples as mine (they are exactly from the same place) are ground and polished - they show the cellular structure. Those. these are stems without external "bark".

[Svetlana]

To be continued.

Have a nice evening

Thank you for sharing these- they are so different from the typical types of Carboniferous flora preservation that we see posted.

[Nimravis]

Very nice and you put a lot of time and effort into this post.

Beautiful specimens; thanks for sharing. Have you tried finding literature specific for your locality? What was the depositional environment like? Could very well be that you are dealing with an upland flora here, which contained different floral elements from your typical lowland "coal swamp" environment... Have you considered things like Walchian conifers?

Hello.
I like them very much too. The fact is that we have many mines, and i will not surprise anyone with prints on coal shale; Also, in the Araucarite layer of the Carboniferous period, there are many fragments of large-diameter trunks - they are all very poorly preserved, ferruginized and recrystallized. There is no  wood structures or small details (such as knots). But in one place I was lucky to find one lens,  a few meters in area, where there were only small branches and of exceptional preservation - small details and knots were preserved. Before that, there were no such finds here. Probably, large trunks and small branches were "sorted" by the current and I was lucky to stumble upon a place where such a valuable material had settled.

Hello, Tim.

Will copy to you previous post:

There is, of course, literature about Donbass and finds from here, but it is very scarce and concerns just large, poorly preserved trunks. These fossils definitely come from the Pennsylvanian of Carboniferous period (303.4 Ma).
I quickly looked through the information about Walchia - thanks for the tip, I will study.

Have a nice evening

I continue to sort out the finds over the season and here are some more interesting stems from this place.

Heavily destroyed stem, but the core is clearly visible, which is broken off just at the extension (in the middle of the "barrel").

 

[Svetlana]

Heavily destroyed stem with the core and knot

[Svetlana]

Nice tree stump

[Svetlana]

One more

[Svetlana]

Broken branch - whorled knots can hardly be seen

[Svetlana]

Heavily recrystallized whorled branch

[Svetlana]

And one more

[Svetlana]

Flattened stem with several knots (it consists of two parts)

[Svetlana]

I will continue to add to this post.

Have a nice evening

Hello to all.
I noticed an interesting structure on two of my samples - you can see it on the end of the hemp.
Unfortunately, the second sample was burst along - but such a structure is visible on it; moreover, it has whorled knots.

First one

[Svetlana]

If at the end of the first hemp these structures differ only in color, then on this sample they are, as it were, pressed inward - you can feel it by touch.
