Leaf Stem in shale perhaps

[cngodles]

Went looking for ferns and plants today. Spent my lunch hour splitting shale nearby. This one caught my eye. The ghosted pattern around the stem is interesting. I feel like it’s part of it seeing how symmetrical it is. And ideas?

 

Length of the stem part is 2 1/8” (Don’t have a metric ruler handy)

 

To me, the bottom portion is the base, so the shape is confusing.

Hmmm. Intwiguing.
