Odd shaped concretions: crab homes?


The Mushroom Whisperer

Recommended Posts

Hello all,

 

My friend gave me some odd shaped concretions, and I was wondering if anyone has experience preping any like these?

Sorry, I put it in the tag and forgot to add it to the narrative.  Lincoln Creek Formation.  He wouldn't give me more than that!

Resemble peanut and potato crabs from the Permian perhaps par-boiled by proto humans.  Or not. :muahaha:

The nodules at Twin Rivers (i think that's the name) on the Olympic Penninsula look a bit like these and have callianassid shrimps in them.

Many, many years ago when I was about 9 we found a bunch of peanut shaped concretions in one of the Virginia or Carolina states. We’d throw them in the fire and they’d pop like a gun shot. They had a hollow core. I image it sent shrapnel type pieces flying.

Interesting.

If I have the time, I'll start prepping these tomorrow.

These could very well have a fossil inside them.  The safest thing to do is try and determine a 'flat' side on them and then dig a hole and try to find a carapace.  The big elongated one I doubt has anything?   If your super lucky, you will have some crab doubles.   Good luck
