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
