Crinoid holdfast?

[Collector9658]

I collected this echinoderm part from Silurian Bainbridge Formation outcrops. There are two spike-like projections exposed, and two more that are buried in sediment. The rock unfortunately split in 2 pieces, and I noticed two other spike-like projections on the opposite side while glueing it. I thought it looked somewhat similar to an Ancyrocrinus holdfast, but the age is wrong and I haven't found them reported from here. I apologize for the poor quality photos, I will update with better quality ones when I relocate the specimen. Any clue if this is a holdfast indeed, and if so what crinoid it could belong to?

I would say this is a holdfast, if I found it.

I thought so too, but I'm having issues with finding a type of Silurian crinoid with a similar grapnel holdfast like this.

Definitely crinoidal, could be holdfast or just a stem section. Those "spikes" could be from cirri. Hard to tell just from these photos. Can't help you with ID beyond that, as holdfasts/stems are usually hard to ID unless they are very unique/characteristic.
