Odd Fossil With Incorrect Label

[Scylla]

Hi TFF. I hope you can help me with this mystery. I found this unusual fossil at a rock shop in Northern California for only $15, so I figured I would grab it for that price and figure out what it is later. How hard could it be? I had the label and everything. Well, now it is home in New York and I think the label must have gotten switched because it looks like a mispelling of a trilobite. The fossil gives off crinoid or rhinocarid/phyllocarid vibes, but I just can't tell. Any ideas?

Possibly Gogia, an eocrinoid,

which occur in Wheeler Shale in Utah.

 

 Better up close photos will help.

If this is from the Cambrian of Utah, I think what you have is cystoid Gogia spiralis, found in the Middle Cambrian Wheeler shale. For comparison:

Looks like a Cambrian Gogia eocrinoid. I'm not too informed on eocrinoids but based on what I see of the arms I don't think it's a G. spiralis, which has squiggly spiral-shaped arms as the name suggests. The arms on your seem more straight.

Gogia kitchnersensis that was pictured in my first response has straight arms and occurs in Utah. Further details on the same Wiki photo say that it is from the Spence Shale in Antimony Canyon in Utah.

Thanks, I think you guys have solved it. I will check some Wheeler shale under the microscope side by side to confirm.

Pretty sure @DPS Ammonite called it. Looks really good. Great buy.
