hdesousa Posted March 10, 2023 Author Report Share Posted March 10, 2023 Bought from Stan Block in 2000. Looks just like a common German limestone marble, except it has a fossil. I was told they come up every now and then, but I've never seen another. 1 Link to comment Share on other sites More sharing options...

I was told they come up every now and then, but I've never seen another. That is unusual - really cool. Of course, there are some limestone deposits that are chock-full of fossils. It's almost surprising marbles like this aren't more common. But this is the first one I have seen. It kinda makes all the other limestone marbles seem lame - the best I have are dyed - big whoop! lol 2 Link to comment Share on other sites More sharing options...
I'llhavethat1 Posted March 11, 2023 Report Share Posted March 11, 2023 I think those are called cryonids (or something like that). Seen plenty of them in rocks but not a marble. Cool 1 1 Link to comment Share on other sites More sharing options...

lostmymibs Posted March 11, 2023 Report Share Posted March 11, 2023 It is a crinoid.Crinoid - Wikipedia Those are fossilized stem segments. The bottom segment in your example is a cross-section and shows the fivefold symmetry. neat marble! 1 Link to comment Share on other sites More sharing options...
bumblebee Posted March 12, 2023 Report Share Posted March 12, 2023 Wow, that's neat, but I suppose it makes sense given the material that these would show up once in a while, but that's a new one for me. Link to comment Share on other sites More sharing options...
