Pennsylvanian - Northeast Ohio Found 8-26 What Is It?

[saysac]

Found this in my favorite spot. Too large for me to carry out on my own, and not certain if it is worthwhile to keep? Any way, any idea what it is?

[ZiggieCie]

No idea on plants.

Definitely a leaf present in the last picture (meaning this is probably less that 150 million years old). I'd keep it

This could be a partial lycopod pinnule, and it should be as old (Carboniferous) as the other fossils in the formation.

The large feature in the slab is probably decorticated bark.

My mistake, I didn't register the title. Certainly a pinnule

I wondered what the big piece was, but was not sure of the what you think is bark.

It seems that these plants had many layers of "bark", and the deeper in the trunk they were, the less they looked like the recognizable outermost layer. They also had a habit, it seems, of 'delaminating' after death.

[saysac]

Well actually, the layers of bark makes a lot of sense. If you think of the trees in the yard some have a very heavy outer bark but softer layer if pealed away. Thanks for the explanation Auspex!

I'm pretty sure it is a very large cordaites leaf.

I like that too, and you are probably right. I initially thought the texture was a bit too rugose for that, but that could easily be an artifact of the preservation.
