Hi, @ian-Kinney it does look like a weathered crinoid stem to me. Do you know where it was found or about what age rock it is in?

This fossil was given to me but it’s origin was not.

this almost looks like part of a trilobite…

Would love someone to enlighten me all about what I got. I believe it’s a crinoid fossil make of Limestone.

@ian-kinney how hard is that rock? I used to find chert nodules like this with weathered out crinoid bits

@jbauer, it’s not fragile feeling at all, it’s hard and dense. I’m guessing it weighs about a 1 1/2 pounds. It’s an irregular shape and it’s length measures at 5″, width at 3″ and height at 1.25″.

@ian-Kinney – at first glance, it’s very similar to weathered chert I’ve found. This is a form of silica/quartz if you are unfamiliar. Can have many different colors. I say this because if it was limestone I would expect the rock to have weathered away with the fossils – since they are the same material calcium carbonate.

what do you believe I would see if I cut the fossil in half?

@jbauer thank you for clarifying that for me and that makes sense taking into consideration that the area that I was digging is rich in quartz rock/crystal
