Petrified wood or dinosaur egg?

[Kathleen Anne]

I have this strange item that came from a rock wall in my yard constructed in the 1930's. The wall is constructed of petrified wood, quartz, and others that I am trying to identify. The cement in the wall is crumbling and releasing these rocks. This particular one caught my eye because of the unique shape and color. To me it looks like an egg because of the rounded end. Does anyone know what this is?

Looks like wood to me. The annular rings are quite evident. Nice specimen!!

Thank you, that's what I kind of thought too when I saw the rings.
