Large Crinoid

Recommended Posts

I was out fossil hunting and was seeing some small shells and pieces of small crinoid. Then I came across this giant. It is 2 pieces of crinoid stuck together in matrix. I am used to Cretaceous fossils not Pennsylvanian. Does anyone know if this is large for a crinoid? It is the largest one I have seen but I have only looked for crinoids 3 or 4 times before.

 

Size:

 

Longer one is 16mm in diameter.

Smaller one is 14mm in diameter.

I have seen a couple of them that were close to that size in the Pennsylvanian exposures around Jacksboro.  Still...not TOO many of them!  Nice find!

Decent find. :)

That's huge. There's only one place in North Texas I know of where 14mm diameter stems are common. Here's the biggest find from that site.

Thanks! I found this one in Missouri. It was actually an accidentally find. I was searching a small 5ft by 5ft rock cut while on a walk and saw nothing at first. I saw a couple of crinoid fragments and just as I was about to walk away a circular shape caught my eye. I looked closer and found this. I have been cleaning it and will post some pictures to this post tomorrow. While cleaning I found another piece branching off. Will post in morning probably. :)

Here’s the back after being cleaned up. You can a piece branching out of the main stem. Do you think I should leave the two big pieces stuck together or try to separate them into two pieces? I may wait until I return to Texas before taking them apart because then I will have some better tools. I don’t think it will be too hard. It is just a small section of matrix.

Please do not separate them, they look so nice sitting together, and they have been that way for many lifetimes!

I agree, leave them together, much better. 

Love the cirri branching off. :)

Ok I won’t separate them. I agree it is cooler to have two giant pieces stuck together. :)

Very nice. :)

Though it could be from another crinoid. 

Unless it fits exactly with one of the pieces you already have, of course.

I just seems like they should be the same crinoid. Same diameter and found within a foot from the other piece. It could be erosion. Or maybe it’s just that I want to have a bigger crinoid and my brain put them together:rofl:
