Good afternoon (for those in EST),
I found this while hunting for marine fossils and was wondering if someone could identify this for me. This was found in South Bend Indiana and is approximately 9cm long. It doesn't look like the typical crinoid or sponge to me. Whatever it is, it doesn't seem to be very rare as I found a lot of these. It could be geologic but something about the way it is laid out makes me think otherwise. Thank you for your help.
