I wonder how they cement in that shape do you know the process in which this occurs? I agree as well. Link to comment Share on other sites More sharing options...

This could be the interior of a single concretion. The gaps represent cracks or septaria. These can form by shrinking of the sediment by dewatering and mineral replacement during diagenesis.

JustinFL Posted August 14, 2017 Share Posted August 14, 2017 I find the same thing pretty frequently in the venice area. I have asked around, but never gotten a definitive answer on what they are. Link to comment Share on other sites More sharing options...
