Is this a whale bone?

[milesdomecq]

I'm thinking this a whale bone, maybe a humerus?

Found in Mendocino, California. Thanks for your help!

Size/Length please.. @Boesse is one of out whale experts and also has spent some time in California.  I am wondering just how big a whale humerus might grow.  Let see, I wonder what a humerus for a Blue whale would measured out.

It is approx. 24" tall and 15" wide (max).

It was collected in the 1970's and I do not know much about it.
