Flora, Fauna or mother nature messing with me?

[Kato]

While out before a snowstorm hit the area I was in search of fossils in different areas back in a deep canyon. I found this on a slope for an area known for Silurian/Devonian formations. The Devonian (Sly Gap) is known for sandstone which this specimen is in. Above that it is Mississippian with no such sandstone that I am aware of.

 

I'm gathering some samples to begin learning fossil prep. As this is sandstone, I recall from college using DMSO to loosen sandstone matrix...so it was going to be a sandstone experiment versus the limestone specimens I've got lined up for when my vibro engraver shows up.

 

Anyway, enough babble....any ideas? Length is 2" on the dot.

Looks mineral to me. Lets see what others say.

Can't say I've seen it identified, but the little voice says graptolite.

I can work with the thought of graptolite and the timeline seems appropriate. Thanks!

Try dendroid graptolite

Possibly algae. Maybe something like Rhodophyte.
