[Rockhounds] Salmon Creek poop (NOT)

[pmodreski at aol.com]

That's a great article about coprolites, Tim, thanks for sharing the link.

Aside from the Salmon Creek "coprolites" probably not being real coprolites, I talked with Karen Chin once when she gave a lecture about coprolites at CU (I mean the lecture was at CU, not the droppings)... and she expressed some doubt about whether the warty-looking chalcedony nodules found in western Utah and thereabouts and generally known among rockhounds as coprolites, also really are.? For a couple of the same reasons: no phosphate content, and no visible partly-digested plant or animal fragments embedded within them.? I don't think anyone has really subjected those Jurassic supposed-coprolites to any in-depth scientific study--Karen said she personally had never studied those--and until someone does, I think their status will remain questionable; though all the rockhounds recognize them and rockshops sell them as?"coprolites".

Pete

A very well thought out article on the "coprolites" from Salmon Creek WA.
