Trying to Identify Marks on Geode


AlaskaMan

Recommended Posts

I found what I think is a geode in a small stream here in Vigo County, Indiana.  Brought it home and discovered all these unusual circular patterns along the narrower edges.  Looks like urchin but I have not been able to find a similar type online.  It does not feel hollow. Has anyone seen a similar surface patter on another specimen?

+1 for Beekite rings.

Caused by geologic processes, not a fossil.

Thank you all for your knowledge.  Yes, it is a wonderful example. I think I will try to clean it.

Nice beekite. :thumbsu:
 

Although it is caused by geological processes, and not in and of itself a fossil, it can be found in conjunction with fossils. Check out this thread.
