My Carboniferous collection

[Svetlana]

A very interesting find from the layers of the Carboniferous period (303.4 Ma) is a long branch with a large knot.

I'm just overwhelmed at the abundance of mineralized and well-preserved wood which you are showing us.

Roger, thank you.

Will add few new species today; may be, you will be able to help me identify it

Sorry, but I'm not very good with wood. I'm just enjoying them.

Hello.

Interesting cylindrical formations on a petrified wood sample; also it has crystalls of smoky quartz

Thank you for your wonderful and time-consuming work! Tell me (maybe I didn't read the branch carefully), do you have wood with traces of woodworms?

Hello.

I have only two fragments of Carboniferous wood, eaten by molluscs - super rare finds for our Carboniferous; and have mucch more Paleogene wood, eaten by Teredo.

By the way, this sample is quite similar to a modern tree eaten by carpenters during their lifetime. I wonder how to distinguish damage to a tree made by a land borer from damage caused by a Teredo mollusk?

Carboniferous, 303,4 mln years

An interesting fragment of a petrified wood of the Paleogene period, replaced by opal, in which black dots are visible - insect coprolites, was turned by me into a sphere.
Unfortunately, there were no more similar samples of wood with coprolites.
