A set of four coprolite fossils. They look like exactly what they are - fossils of animal dung!
This Fossil Friday is a set of fossilized droppings (coprolites)!
These were collected from the Late Cretaceous rocks of Saskatchewan by Karen Weinhold.
This is APS 1990-004, and the scale bar is 1cm.

Iron carbonate protects molecules in ancient coprolites, study shows
Curtin University researchers found iron carbonate grains preserved biomolecules in 300‑million‑year‑old coprolites from the Mazon Creek site (USA), revealing a way to study ecosystems. getnews.me/iron-carbonate-protects-... #ironcarbonate #coprolites

Christian here.
I see some pastors are preaching #Christian #Domination.
Yeah right, cuz #Jesus preached domination. I think that was in verse #Coprolites 3:19. #Hypocrites #Repent
George Frandsen is the owner and curator of the Poozeum, the largest private collection of #coprolites. As an invited speaker to this year's @geosociety.bsky.social session T154: Coprolite happens, I and my co-chairs are very excited to learn about his work with coprolites. We hope you can join!
We are looking for a #PhD Student in our group on "Environmental versus host controls on #parasite diversity in #Permian-#Triassic #vertebrate #coprolites" in the NCN project "The impact of mass #extinctions on parasite #diversity and #evolution".

I summarize the results of a really cool paper just published about what we can learn about dinosaur diversification from studying dino droppings and vomit. Then I take a twist on it and show how this data should cause many creationists to lose sleep. youtu.be/8k5LUAXBjn4?... #dinosaurs #coprolites

Fantastic, I also like to collect #coprolites . I found a fish one last week, from the Peterborough Formation. Spotted a small vertebra inside.

Poop humor is always a sure-fire way to get a child audience’s attention, which means #coprolites get a lot of traction in paleo outreach. To that end, may I recommend “The Clues are in the Poo”, coauthored by Jane Kurtz and #coprolite queen Karen Chin!

For someone who proclaimed her avoidance of all things gross, here I am back for a second week writing about just that. This time it’s “poo,” dinosaur poo. bit.ly/3QZhpd4 @writerjanie #dinosaurs #coprolites #picturebooks

#Coprolites, why did it have to be coprolites? - Yeah, it‘s 💩 research, but someone‘s got to do it. 🤷🏻♂️😉

I just finished working on #Pleistocene #groundsloth #coprolites from a New Mexico cave. So, for #FossilFriday here is a plate of #CalciumOxalate (#CaOx) #phytoliths from said poop. I rarely get to work on CaOx phytoliths and make use of my polarizers so this was a treat! #2is#1
