Agree with @rockpickekrforever. Fossilized algae.

Okaaaaay... So what is it, Dan? Dying to know. I picked some up at a show (sometime, somewhere) and cabbed it -
I am sure this is same stuff. (sorry for lo-res photos)

Hmmmm, Maybe the same issue exists with Wamsutter stromatolite as with Turritella agate. Turritella is a salt water snail but the Wamsutter material is Goniobasis, a brackish water snail. Maybe stromatolite, like the big Aussie stromatolite is a salt water stony algae while the Wamsutter stuff is brackish water. So what does your guy say it is? Here is Wyoming material with the algae growth around a petrified wood log. Here is Wamsutter "stromatolite" or what we've always called stromatolite. Dry here. It's brown wet.

OK, hate to disagree with your expert but that specimen is an Eocene Phanerzoic stromatolite. Chlorellopsis sp. a cryptozoan stromatolite common in the Green River formation. Looked it up. Not pulled from my own feeble brain *S*...Mel

I should all ways double check.

Rockpicker: That formation extends over several states. I've seen it from Wamsutter but it is also found in Colorado and Utah and lots of areas in Wyoming.....Mel

This is a fossil stromatolite. Chlorellopsis is the correct name. The material found along the Delany Rim that runs south of Wamsutter to Rock Springs WY. It is from the Eocene. It is very common material. The locals seldom pick it up since it's so common.
