Trilobite of the week #374 is Micragnostus chiushuensis of Late Cambrian age, from the Sandu Formation at Jingxi, Guangxi, China. This is a tiny trilobite, about 3 mm long. The Basilicus weighed about 3 million times as much. As is often the case with agnostids, I'd give about a 50% chance that I have this one shown heads up.

You are mixing your stratigraphic terms. Early, Middle and Late refer to Ordovician epochs, not series. Epochs are divided into ages and not stages. The Cinncinnatian Epoch and Richmondian Age are local terms and not used in newer stratigraphic charts such as the one from the GSA:- 6 replies

#1 could be some kind of tusk shell fossil, but I can’t tell exactly just trying to help.

@JD1969 Please correct the spelling of meteorite in the title and tags otherwise few will be able to search for your post in the future unless they also misspell meteorite. You have two days from the post creation to edit. You can bring your rocks to the Mineralogical Society of Arizona meeting in Paradise Valley to get mineral experts to look at it. https://www.msaaz.org

Thanks! I considered ray plate but it didn't have any of the characteristic ridges. Can anyone confirm if the croc tooth is likely to be Eosuchus minor? Any thoughts on 6?

I've often wondered about the actual provenance of this fossil. It's said it came from near Uvalde, in the Buda limestone... but I'm extremely skeptical of a Buda limestone origin. Apart from this, I've never seen nor heard of Ptychodus out of that formation. I've been told Shawn Hamm saw this specimen and guessed an ID of P. decurrens. The preservation and matrix of the Mexican specimens reminded me of this one instantly, and the only ID that the authors on the above paper made with confidence was P. decurrens on one of the specimens. The Texas through time specimen has no work done on it that I'm aware of, I hope someone spends some time with it and looks at the matrix. I have a suspicion it might be a wayward mexican specimen, but for now who knows.

I found it on the beach in southern Delaware. I've also found 2-300 yrs old pottery shades, arrowheads and sharks teeth along with mostly plant fossils and numerous bones of various origins

Certainly, we need more skepticism in this world. I too look forward to independent analyses. I think this apparent "leap" in understanding is due to a leap in evidence; we went from naught but teeth and denticles to complete articulated body fossils with soft tissue. A specimen of a similar caliber that should be included in future work is the articulated specimen in the Texas Through Time museum, which I'm sure you all know about and may have seen. It too looks to be a low-crowned species.

Ha de ha! Yeah, funny that. Thanks for looking and commenting. Thanks, Mike. If you do get around to getting some of this marvelous matrix, it would be nice if you posted some of your finds here. Yeah, I started off with a particularly nice one that was perhaps a bit easier to identify. A lot of them are just like this one: Nice enough but not too thrilling Maybe one of several genera. @Anomotodon, hello,old chap, could this be Anomotodon novus, a goblin shark? Thanks, mate, nice that you found the thread. And, yes, enormously generous and a lot of fun!. Thanks, Jamie, lots more weird and wonderful stuff to come, it's very productive matrix, you'd love it. And I'm sure your super photography skills would do the specimens far more justice than my shoddy snaps. Very kind of you to say so. But I'm mostly relying on elasmo.com for the ids and it's making my head spin. I have no idea what I am doing, really. As usual. Thanks, Waynesville Formation, I expect somebody will be along who knows the material sooner or later. in the meantime I shall have to read a bit more

My vote: not a meteorite. Iron meteorites as their name suggests are >90% iron, are extremely dense and will absolutely stick to a magnet.

Fossils in FL panhandle(?)
Shellseeker replied to OverCaffeinated's topic in General Fossil Discussion
I have lived in Florida for 30 years and hunted extensively for the last 30 years.. in Southwest Florida. Fossil hunting is not as easy in the Panhandle. That seems to always be true. Someone asking for help and getting no answers. So this is going to be hard... Nothing easy like just asking. Depends on whether you can do hard things over time. Do you live in the panhandle ? That is a good start... Florida is full of fossils and has tons of rivers and creeks. On your weekends or free time, start investigate those rivers and creeks. The state of Florida owns 95% of all creek or river bottoms and grants you the right to walk on those creek/river bottoms. Here is an OLD , OLD OLD map that was prepared by the University of Florida to tell people where they believed there were fossil locations in the State. Who knows.. there might be a fossil or 2 left at those old sites... on the map in the panhandle. https://original-ufdc.uflib.ufl.edu/UF90000378/00001/1x If you want to find fossils in the Peace River, it is pretty easy.. but in the panhandle, it is not. -
Welcome to the Forum. Not sure on 1 and 2. 2 does look like a brachiopod on the upper left, but then maybe the inside of the shell is below that? Not sure. 3 could be a crinoid stem, or an orthocone nautiloid/cephalopod. 4, 5, 7, 8 are all crinoid stem/columnal pieces. There are some bivalves and brachiopods mixed in with them. 9 looks like the imprints of crinoid calices, or crinoid "crowns" . 6 looks like counter septarian structures, to me.

Welcome to the Forum. Give us a better, more specific locality and we may be able to determine the age of the oyster and what rock layer it came from.

This was found in a dry river bed inland from the west coast of California. Would appreciate some help IDing it. Could it be a scallop shell fossil? Thanks for the assist.

FossilNerd replied to Newbie_1971's topic in Fossil Hunting Trips
I think you are on the right track and of course agree with you. I know he usually hunts in areas similar in age (if not exactly the same) as St. Leon, so I think your assumption is right with Richmondian in age. I’d even venture a further guess and say he typically hunts the Liberty Formation looking for the flexi rollers found in the “butter shale” there, but that is only an educated guess from his previous finds and these might possibly have come from other Richmondian Formations like Whitewater, or Myville…errr… I mean Waynesville…- 6 replies
