Unidentified perfectly round rock with bumps.

Hi
My father found this strange round rock buried in soil when he was digging out a foundation in northwestern Oregon. The soil here is not very rocky- so pretty strange. The bumps are also weird. Ways maybe 15 to 20 lbs. anyone happen to know what it is? Thank you!

I do not think it is a Thunder egg. Possible it is in the fossil family of Cretaceous. Hopefully a rock hound will chime in.
Cool rock lets get an I.D.. We have a great fossil a and rock forum on this site you might post it it there as well.
Thanks for sharing your unique find.
