I thought I better post a legitimate coprolite contribution.

jasoninsd what did you use to take above photo? It looks a lot prettier on my phone screen than my laptop.

I thought I better post a legitimate coprolite contribution. I notice that little crumbly pocket at 7 o'clock. I occasionally find these in coprolites and I have assumed they are simply regions that did not petrify for whatever reason. They often seem to be much less dense material and even "rotten." Nice green color, btw.

I occasionally find these in coprolites and I have assumed they are simply regions that did not petrify for whatever reason. They often seem to be much less dense material and even "rotten." Nice green color, btw. I've cut some pieces recently - Thundereggs and a Black Skin Agate, which have some tubular formations in them. In some of the tubes, the interior of the tube is a greenish color and seems solid. But in some of the tubes, they seem "hollow" and dried out. It reminds me of the crumbly pocket in this one. They're probably completely unrelated, but there seems to be a similarity to me. I was going through my slabs of coprolite last night and was thinking about possibly making some cabs out of this one. However, there were more fractures in this piece than what I originally thought. It could still produce some cabs, but I was wanting some a bit larger than this piece would allow. So, I picked out some other poop pieces. I suppose that "crumbly" section could just be uncooked cookie dough though! LOL

That crumbly stuff looks like blue cheese crumbles to me.

My mother and I were at a rock show, and she was buying pieces for resale at her shop. I held out a lovely polished slab that was mounted on a stand and advised her to buy it. She asked what it was and I told her... she was disinclined to purchase it. I assured her it was a good price and that someone would want it. She finally did buy it. Wouldn't you know it was one of the first things she sold? At a good profit too!

Seems the tourists are mostly buying it in southern Utah rock shops I frequent and I'd guess the novelty of it is attractive.

This photo is significant because that dark layer is a marker for the Morrison formation in southern Utah which is what I watch for in my coprolite hunting endeavors. It's not always present as depicted here but it generally helps my efforts.

One of the things that has piqued my curiosity is the number of dinosaurs that have roamed the earth. If you think that the human population on earth is more than 7.5 billion people and we have only been wandering the surface of this planet for a couple hundred thousand years, how many dinosaurs dominated life for 165 million years, how many dinosaurs were alive at any one time? Over that 165 million years? It turns out, some scientists have made some calculations for T. Rex. Based on lifespan, size, etc., they estimate that 20,000 lived at any one time and survived through 127,000 generations. All that means that some 2.5 billion T. Rex existed over a span of 2.5 million years. Here's a link to the article on CNN. If that number isn't mind-boggling enough, they also estimate that only 1 in 80,000,000 T. Rex skeletons remain as fossils. To keep this post on topic, the average lifespan of a T. Rex was in the late 20s. If a T. Rex pooped once a day, at an average lifespan of 25 years, T. Rex would have pooped 22,812,500,000,000 times. That's a lot of poop. Edited to add link to original story in Science Magazine: science.sciencemag.org/content/372/6539/284

The amount of dino dung produced must have been amazing.

A cow can poop up to 15 times a day." Just a quick Google search and this was taken from fergusonfoundation.org/lessons/cow_in_out/cowmoreinfo.shtmlSo, if a cow can poop 15 times a day, I think the large herbivore dinosaurs may have that beat...which makes your number of lifetime poops slightly larger in fact... I tried to find the amount of times an alligator or crocodile poops in a day, but I just found information that their poop is white...and really smells. I thought a crocodilian might be a closer comparison to your T-rex numbers, but I was thwarted on finding out any more info on their bowel movements! LOL

Consider this: An elephant can poop up to 300 lbs. a day. That's 54.75 tons a year. An African elephant can live up to 70 years. That's 3,832.5 tons of poop during it's lifetime.

Well, at this stage o’ the game, I’m good for about thirteen tons.

LOL I also saw an estimate that large herbivores would have generated about a ton of poop a day. That is a lot of poop. I did the same search on alligators to see how much they pooped and spent way too much time reading about why their poop turns white while not finding the info I was looking for.

Gotta love where the twists and turns of the conversation on this thread can lead. It's now getting more clear why I've found literally "rivers of coprolite" on some hill sides. All that was probably required was an area with a bunch of hadrosaurs that got a flash flood or an ash fall, or some other burial event, and bingo, there's a bunch of turds covered with dirt just waiting to petrify.
