Is this a blastoid?


Recommended Posts

I found this on partridge point in Alpena MI in Devonian limestone and have been finding crinoids and blastoids. I’m not sure what this is.

I almost see the star shape of a dirty, sediment covered Cincinnaticrinus pentagonus stem. 

However, I am not seeing blastoid.

I agree - possible crinoid columnal.

I agree it’s probably not a blastoid. It’s actually not very covered in sediment and the end is almost bulbous when you look closely. Do you think it could be the end?
