Meganeura Posted May 21, 2022 Share Posted May 21, 2022 Found this in some gravel near peace River - not sure if this is coprolite or not, wanted to get some opinions! Still very new on identifying most fossils. Fossils? I dig it. Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 21, 2022 Share Posted May 21, 2022 Could just be a phosphate nodule. 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Meganeura Posted May 21, 2022 Author Share Posted May 21, 2022 Considering it's from a phosphate mine, that would make a lot of sense. Thanks! Fossils? I dig it. Link to comment Share on other sites More sharing options...
digit Posted May 21, 2022 Share Posted May 21, 2022 Yup. I see a lot of phosphate nodules that get crushed or squished and end up looking a lot like that. @GeschWhat is our local expert in all things coprolitic. Perhaps she'll weigh in with an authoritative opinion soon. At the Montbrook site up here in north central Florida we are digging in an old river system and encounter lots of alligator fossils. Apparently, gators digest their food (turtles, fishes, birds) so well that the bones are dissolved as well. Excess calcium that is not needed by the gator is expelled in their waste. Gator coprolites that we find (fairly regularly) have the consistency of drywall--quite chalky. This is likely what preserves them preferentially over other species. When picking through the micro-matrix from Florida sites (Peace River, Cookiecutter Creek, Montbrook) I find tiny coprolites (likely fish but possibly other types of animals) to be quite common. The first image below was composed by Lori (our Queen of Coprolites, Duchess of Dookie), the other two are my assemblages of coprolitic diversity. Next time you are out fossil hunting you might consider collecting some micro-matrix to pick through at home.

Also Ralph already got me onto microfossils so I'm probably gonna collect some when I head out to Peace River tomorrow, hold onto it for when I get a set of smaller sifters. In other news though, I swear I have a couple of those mini-coprolites that I thought were just shells, I'll have to look to confirm but that's really near regardless! 2 Fossils? I dig it.

digit Posted May 21, 2022 Share Posted May 21, 2022 Nope. A coil with a decreasing diameter is more indicative of an internal mold (steinkern) of a gastropod (snail). Cheers. -Ken 4 Link to comment Share on other sites More sharing options...
GeschWhat Posted June 27, 2022 Share Posted June 27, 2022 Sorry I'm chiming in so late. I don't get much of a chance to check in on the forum much anymore (making sure coprolites aren't forming in my grandbabies diapers). That looks like a coprolite to me. It appears to have a pinch (sphincter) mark on one end. @Fossildude19, I'm really curious. If there is a phosphate mining in Florida, could they be mining coprolites? I know they used to do it in England. In a super quick Google search I saw a mention of phosphate pebbles being found and mined along the Peace River as early as 1888. If what they are mining calcium phosphate, I would bet it is coprolite. I would love to see in situ photos of what they are actually mining. 1 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
