Fossil Identification- Potential Calamite Cone?

[GooseScroll]

Good afternoon,

I have submitted photos of this fossil to multiple local groups in hopes of a possible identification to no avail, therefore I have turned to this forum and home to figure this out! I hope it to be a calamite cone fossil but I have been wrong before, so I am asking for a second opinion. Thank you very much!

 

Important information: This fossil was pulled off a shale cliff that is abundant in calamite and fern fossils. The cliff is located near Carnegie, Pennsylvania (Western PA). The specific fossil has both calamite and ferns on the reverse side.

Edit 1: The size is about 1.5 inches (3.81 cm). 
 

Information that is possibly helpful but may not be: The cliff has a few layers of coal and black colored shale, while the majority of the cliff is a grey colored shale. This rock was pulled off just above a black shale line.

Looks more like a branch to me, but maybe @paleoflor knows better.

Almost looks like a growth tip of a calamites. 

Could be a calymostachys, though.
