puck Posted June 18, 2017 Share Posted June 18, 2017 I found this in a rock garden at work. Curious to know what the disk/cylinder is embedded in the matrix. Any information would be appreciated. Thanks. Size is approx. 3 in. x 2.5. Sorry for the link, I had upload problems. Photos: https://postimg.org/gallery/hdwouopw/ Link to comment Share on other sites More sharing options...
Miocene_Mason Posted June 18, 2017 Share Posted June 18, 2017 Looks to be a centrum, the vertebra extends under the matrix it seems, so some prep work might be in order. I couldn't say what animal though, others may know, good find! “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
puck Posted June 18, 2017 Author Share Posted June 18, 2017 Thanks, I'm a total newbie. Could it be from a crinoid? Link to comment Share on other sites More sharing options...

A crinoid is also an invertebrate by the way, here's an example of crinoid columnals I found: They are the little rings “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

abyssunder Posted June 19, 2017 Share Posted June 19, 2017 I'm wondering if it couldn't be something related to ironstone with a Marcasite pattern in the middle. 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

I'm not a vert. Expert but this looks a lot like a centrum, with two processes of the same color, if t is geological it is a cruel joke indeed by Mother Nature.... “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

I agree, but "Pyrite Sun" could be a good joke of Mo Nature.

puck Posted June 19, 2017 Author Share Posted June 19, 2017 abyssunder, I see what you mean. Having to do with ironstone, is that why the disk has a rusty appearance? Link to comment Share on other sites More sharing options...

puck Posted June 19, 2017 Author Share Posted June 19, 2017 It looks thicker than the images of pyrite sun Link to comment Share on other sites More sharing options...
abyssunder Posted June 19, 2017 Share Posted June 19, 2017 Rusty with metallic shine. I agree with the symmetrical teardrop shapes on either side, but I suppose they should be at a same distance from the centrum (in the same elevation) to be the processes. Marcasite nodules are usually spherical, but not in all cases. Maybe it's a half of a nodule. What is the geological time for the location of the find?

puck Posted June 19, 2017 Author Share Posted June 19, 2017 Thanks for the replies! I assume it is from the same area as where found as it was found in a rock garden, with many other rocks. The previous owner of the property also owned a gravel pit in the same area which is, if I'm reading the Bedrock Geology Map correctly, Mississippian.
