FossilsandScience Posted August 7, 2019 Share Posted August 7, 2019 Hey everyone, I am thinking of purchasing this dinosaur Coprolite but I want to make sure it is authentic first. The tag didn’t mention where it was from. Thanks! Link to comment Share on other sites More sharing options...

DPS Ammonite Posted August 7, 2019 Share Posted August 7, 2019 They look like the stuff from Utah that are unlikely to be coprolites since no typical things such as plant/ bones/ shells can be seen.

FossilNerd Posted August 8, 2019 Share Posted August 8, 2019 They do look more geological to me than coprolite, but I’m no expert. I’d wait for other opinions.

RJB Posted August 9, 2019 Share Posted August 9, 2019 Ive seen lot of this before 25 years ago. It was always sold as dino poo and looks like the same stuff. Can say if it really is coprolite though? RB Link to comment Share on other sites More sharing options...
GeschWhat Posted August 15, 2019 Share Posted August 15, 2019 The jury is still out on that type of "coprolite." It is more likely geological. I file these as dubiocoprolites. Not worth that price, for sure. Here is an example of real dino poo. It contains undigested bone inclusions. Without evidence of dietary inclusions (bones, scales, plant material, etc.) or backfilled burrows from dung beetles, it is impossible to identify them positively as coprolites. 5 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
-Andy- Posted August 15, 2019 Share Posted August 15, 2019 I was told these are agatized pseudomorphs Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday! Link to comment Share on other sites More sharing options...
Abyss Posted August 24, 2019 Share Posted August 24, 2019 I'm really curious to know the same thing as the OP in regards to the picture he posted, because I've bought some thinking it was coprolite & couldn't find any answers plus many people are selling it as that. My thoughts, out of all these years no one can(or did they ?) come up with a definite answer is this Dino coprolite or geological ? I'd think someone might of did some kind of tests out of curiosity, what are these made of. Instead of I think its this or that. Link to comment Share on other sites More sharing options...

We know exactly what they are made of. The problem is that we can not be sure of what they were before the current material replaced what they originally were. We weren't there to check it out when it happened and if we start an experiment today to make that determination it will be at least a few thousand years before we can see the result, and possibly millions of years instead.
