This is what I call my dinosaur egg! I found it on the South coast......has anyone any idea what it really is!!???
Thanks Sue :-)
This is an iron-rich concretion in a sedimentary rock (which might be ironstone).
The rusty colour is because the iron is in a mineral form.
I give an explanation of concretions in a couple of my posts in this topic
But by all means continue to call it your dinosaur egg, but preferably somewhat tongue-in-cheek!
