A Marine Fossil Project Options

[swizz]

I collected this in northern Colorado earlier this year from a layer that has always been productive for me.
It is a fairly good sized Ammonite and I believe more than 50% of it is there but still encased in layers. I haven't cleaned any of this piece yet nor tried to extract anything, this is how it came out of the earth.
I have a conundrum because.... the closer I look, the more little treasures I see protruding from the layers that are protecting the Ammonite. For example, if you zoom the first image and look at the upper right area... there's part of a small black tooth with it's jawbone/gumline exposed. There are also tubeworm or nymph fossils partially exposed. I want to see more of the Ammonite but it'll be a tricky extraction as these other tidbits are equally interesting.
I may start with just warm soapy water and a toothbrush.
