Is This Fossilized Coral or Bone or Cement

[NJArtifactFinder]

Hello Everyone,

 

I am so thankful for your insight.  I have recently purchased a few books on Indian Artifacts and look forward to reading them so as to stop pestering.  

 

Anyway,

In Florida on my own property I found several interesting and beautiful things after Irma.  Our property on Marco took a direct hit and many of the trees on our property  and the Seawall went into our garage.  I ventured outside  to see what I could find. 

 Can someone please tell me if this is Fossilized Coral or Fossilized Bone?  My brother thinks it is cement.  I think its an animal skull, and my husband thinks it coral.  In picture 4 there are several deep gouges or ciuts.

 

I will be posting some other pictures of things I found in Florida and any insight would be greatly appreciated.

 

Thank you

Looks like a weathered limestone to me.

Hi Darbi,

 

Thank you for your insight.  What about the shape of it?  And it appears to have agatized in some spots.

[Darbi]

You're welcome and also welcome to TFF! The shape is caused by actions of water, I see all different kinds of shape, like this one, in the rivers all the time. Yes, it's probably pieces or nodules of chert embedded in limestone.

A very artsy piece, that would look nice in a rock garden!  Definitely not a skull, and it doesn’t look like cement or concrete either. I think @Darbi is probably correct that it is limestone, the only thing I would add is there are certain places that look like they could be coral or have coral fragments in them. Sort of like a chunk of a coral reef tumbled around and washed ashore.

This is usually a limestone/calcite combination. It is much harder than the limestone that eroded away. Sometimes flintstones chunks can also be found within these type of rocks. I think the dark grey chunks are in fact flint stone.

Terrific! Thank you very much. I love rocks!
