[Rockhounds] Salmon Creek poop (NOT)

[Tim]

Nevertheless it is interesting that to my knowledge they appears in Morrison
Fm. strata (among others?) right alongside dinosaur remains. Do they appear
in any strata without dino remains? My guess would be no, but then that's
worth, well, not much!

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.
