Very nice. I'll be spending a few days playing along the Oregon coast and might have to look for something other than sunsets :look:

Nice finds... Looks like some might retain their 'wings' and just need a little prepping to expose them?  Is that one totally coated in matrix, or is it a steinkern (missing the shell entirely)?

Just an editorial note: it's Pecten - pectin is the stuff that makes jam congeal.

Lucky! Last time I was out there I found a few, but they were all in huge boulders that it would've been impossible to break them off of! These look great!

The grey one in the upper left is still embedded in the matrix.  I can barely see a tiny trace of shell on the edge of the concretion. 

It seems to be one of those high silica concretions that produce silicified fossils.  It might be hard to prep.

 

The wedge shaped piece has a couple of Calyptraea fossils attached to it.  Too bad they get so beat up from tumbling in the surf with basalt cobbles.

Here's a couple of other photos of it.

Here's a better example of the Calyptraea

Another Pecten in a huge concretion from the Yaquina Formation thats exposed a few miles to the South.

I wonder what else is hiding in that rock.

Someone should have a go at prepping one of those coated ones... that is if there are no already-exposed complete ones to be found. I don't have the means so it won't be me, though.

It must be doable...
