What is it? from the myFOSSIL app 1 year, 7 months ago 1 year, 7 months ago1 year, 7 months agoI dropped this rock to find smooth clay inside? I have all the pieces to put it back together. Anyone know what it is?
This is called a concretion! Its not a fossil but a natural geological phenomenon which happens when sedimentary rocks harden from a nucleus. Kinda cool in my opinion!
in the area I live in we get these in all sizes as a child I thought the may contain a fossil but it was layers of different sediments and calcium
That’s nuts! Looks like a petrified tree nut 🌰 🐿
