I am seeking help identifying this pea-sized fossil that eroded out of the Fern Glen formation  in Imperial, Missouri.
Thanks in advance

Are you sure it is mineralized?  It has some resemblance to a modern seed.

 

Also please do not post the same fossil and question in multiple places.  I hid your post (same fossil, same question) in the other Fern Glen thread.

I agree, this looks like a Hackberry seed.

I agree. Probably modern.

I tried to crush it and it was solid, and it was in the eroded sediment below the Fern Glen formation without many plants nearby.
I soaked it overnight in water, and it is still small and extremely hard.

Now that I see Hackberry seeds, that seems likely.  Identical.
Thanks for the input!

I just read that some fossil Eocene Hackberry Seeds have been found in the Green River formation.
But, that does not apply to my search layers. Thanks again.

As seen here, I also was fooled into thinking a hackberry seed was a fossil. We live and learn!!

 

Was pounding rocks yesterday in an area that provides Ordovician fossils. Amongst the debris I found this. I thought modern seed but when I placed it between my incisors, it felt more rock like. Before I plant this, I just want to make sure it is not a fossil I do not recognize. Thoughts are appreciated

They come directly after diamond on the hardness scale...
