Looks like some rocks and a few well worn bone shards.

Mostly well-worn bone fragments of indeterminable origin, but marine mammal is most likely.

The first specimen is bilaterally symmetrical (likely to be from the centerline of the skeleton), and may preserve enough features to diagnose more about it, with a series of well-lit pictures from different angles.

Okay, thanks...ive got a couple trays worth so its a bit daunting to try and figure out what is what. I know he was very sure that there was no "just rock" but no one is right all the time.

A pics of the contents of one tray as well as a couple specific ones. Are there any recommended places to take all of this to a professional to have it identifed?

Thanks for any and all advice.
