Can't drill a hole in it or break it. Found it in my pas old war stuff he left me. Someone said it was a fossilized dinosaur egg but who knows. Never been on a site like this before so I'm just winggin it with this post. Anyone have a suggestion on what I found? Thanks!

Welcome to TFF from Austria!

 

First, I don´t think its a dino egg.

 

Second, a few questions:

- Is it light or heavy for its size compared with a normal rock (limestone, granite)?

- You say, it is hard and sturdy - have you tried to scratch it with a knife blade or a piece of quartz?

- Whats the shape of the object? Is it rather spherical?

 

I have something in mind (ceramic ball from a ball mill), but the surface texture does not really fit.

I'm not sure what it is, but it's certainly not a dinosaur egg. Check this out.

Maybe a round nodule - concretion? Like WA crab concretions.
