Are these Crinoid Stem?

[Kurri Kline]

These were found in the same place, in black shale, in West Virginia.

 

Are these both crinoid stem?

Thank you for your help!

The tapering gives them the appearance of tentaculites.

I agree - seeing crinoid bits, but mostly Tentaculites.

I was tempted to argue against the idea on the grounds that a better look at the taper was needed, but the shape of the ends of the molds does indicate that the guys are right.

crinoid stem impressions for me

Crinoid stems. Oblique longitudinal cross section of stems gives the tapering appearance.

2 - 2 Judge rules. Closer look.

They could be crinoid arms. Those have been known to taper on occasion.
