Round inclusion

Hi, my son found this in one of our artifact hunting creeks. Can anyone give me details on what this is? He’d like to write a paper about it for his homeschooling work required during the pandemic.

Appreciate any feedback!!

I suggest your son researches concretions. I believe that's what you have there. Cool find.

Your son made an interesting find. There's a good summary of how concretions form at the link below and the fourth picture shows a concretion of the type that he found:

It's a petrified avocado. Very common in California.
