Re: [Geology2] What's in the rock?



I'd have to look at it in person to be certain but it appears to me to be the side of the cast/void of a segment of petrified bone or wood that was embedded in that chunk of rock.

It's from the SW boundary of a discontinuous outcrop of the Coast Range
thrust, a late Mesozoic subduction zone, located 40 miles east of the
present coastline in Northern California. That's the whence and when of
it. Does that help answer the what?
