Coprolite or Iron Concretions?


Recommended Posts

Hi,

Any thoughts on these three? Found in Big Brook, Monmouth county NJ. 

 

They were not together. Don't appear they are from a fire. The area has tons of iron concretions, but these seemed to stick out differently. 

 

Any thoughts if they may be coprolite?

I've collected many thousands of both marine and terrestrial coprolites and have never seen a coprolite cracked like that.  I've collected hundreds of lignitized fruits and seeds cracked like that but these specimens look much more like ironstone concretions to me.

I've collected similar items after being told they were coprolites. Later I read that the common finds on that beach had once triggered a minor, false, gold rush. Eventually they all decay this way if not stored in oil.
