Hi all, I have been working pretty hard to learn and identify my fossils as I collect them. I have one that I need confirmation on. I believe that it is an Orthocone Cephalopod but if someone can either confirm this or tell me what it is if I am wrong, I would appreciate it. This was found near Willow Springs, Missouri, USA. If my studying is correct, it should be from the Ordovician Period and from the Jefferson City/Cotter Formations. It measures a little over 57 mm long and at the widest point measures 22 mm across. The attached image is horrible. I cannot get any decent images with the lighting that I am using tonight. If it isn't good enough, I will take better images tomorrow. Thank you for your time and assistance. Doug

Hello, this is my first post to the site. I was out in Etobicoke Creek last Monday for the first time looking for fossils and had a few good finds. The first is what i think is a Crinoid, . The second one is part of a cephalopod (i think).

We took our girls fossil hunting near our house for the first time. We found rocks with lots of little brachiopods but I also found this. Is this a cross-section of a cephalopod maybe?

So I have partially removed an orthocone from a nodule that I found in some eroded glacial till. The rock is most likely silurian in age but I can't don't recognize this orthocone. It seems to have faint striations running lengthwise down the shell, which I haven't seen before.

Hi again! Two more ID requests - this time they're from the Bangor Limestone in Alabama, USA (Lower Carboniferous, Mississippian). Specimen #1: An orthoconic nautiloid - could it be Brachycycloceras sp.? Specimen #2: A blastoid - Pentremites sp.? Thanks for your help! Monica

To continue discussion on the specimen listed here, with renewed focus on it being a Cephalopod. As of right now, I'm deciding between Solenocheilus and Ephippioceras. Going directly by the book: Index Fossils of North America (1944, 1980 printing), I can see positives for both. Solenocheilus (Lower Mississippian to Lower Permian, IN, IL, MO, KS, TX and Europe) Recommended by a local expert, but doesn't specialize in Cephalopods. Ephippioceras (Mississippian in Europe, Pennsylvanian, Ohio to Kentucky, Nebraska to Texas) The raised line along the midline of the plate photo is what is selling me on this one. My specimen is much larger than the plate, but not quite double the size. So, two new photos of the specimen. First, looking at the line: (After seeing it this way, I was looking at it 90 degrees in the wrong direction) Flipped, End over end. So, any opinions? I was thinking of removing more matrix from the matrix heavy size, but it will certainly remove the shell material and leave the steinkern.

I found this yesterday in Avoca, New York. It's about 3 cm long. The core looks like a cephalopod of some kind, but the exterior has me puzzled. If it were soft tissue, it wouldn't have preserved, but I have found impressions of a few others like this there and in another site over an hour away. The one field guide I have shows nothing like it and I may have to go hunt down the original 19th century sources. Any clues?

So this is a fossil from Beloit Wisconsin found in the Platteville formation. I am pretty sure it is a cephalopod but I have no idea what genus or species. The siphuncle is hollow except for two septa that run right through it. 3" post-it note for scale.

Hey! I just took a trip out in the pouring rain to a road cut in Oglesby, Illinois. This road cut exposes the Pennsylvanian LaSalle Limestone member of the Bond Formation (thanks to @deutscheben for this info!) I found lots of beautiful brachiopods, but as I was heading out, this guy caught my eye. What do you guys think?

I am nearly sure the top piece is Metacoceras. The middle is a clam, but what species? Perhaps Astartella concentrica? The bottom, what is that thing? 6477/6478 show it in detail. I find these a lot. Are they brachiopods? Not shown, but there is a horn coral on the back of the piece in a cross section.

This year I pulled the trigger on heading to Penn Dixie for the Dig With the Experts weekend! Definitely would highly recommend . I drove up from Boston to the Buffalo area on Thursday and spent the day Friday digging with @Malcolmt and @JamesAndTheFossilPeach. It was a blast! Thanks again guys for giving me a lay of the land. Credit to @JamesAndTheFossilPeach for the find of the day with a giant Eldredgeops (pic below). Saturday and Sunday were spent looking for trilobites in the roped off Dig With the Experts section of excavated shale with some success. Monday I drove back to Boston, and stopped to stretch my legs in Glenerie, NY to walk a stretch of road looking for Devonian brachiopods and gastropods. Got a couple! All in all, a great trip... although I'm nice and sore . Here are my takeaways from the weekend. I tried to get a bit of the entire Penn Dixie Ecosystem keeping at least one of everything and as many trilobites as I could find. I wish I took more pictures Saturday and Sunday, but I was too busy splitting shale . Cheers, Barret

A walk down the creek in Longbranch yields marine fossils
markjw posted a topic in Fossil Hunting Trips
A 15cm fossil from "Nautiloid Alley" alongside the creek in Long Branch, Ontario. Also separate images from a "two-fer". For some reason, one sometimes encounters 2 or 3 close together in the same medium sized rock.

5/13/19 Oglesby, IL Roadcut- Pennsylvanian shark bits, brachiopods and more
deutscheben posted a topic in Fossil Hunting Trips
A week ago today, I took the day off work to hit one of my favorite sites, a roadcut above the Illinois River in Oglesby, Illinois. This cut exposes the Pennsylvanian LaSalle Limestone member of the Bond Formation and produces abundant brachiopods as well as occasional other fauna including gastropods, cephalopods, coral, trilobites, and shark teeth. The weather was perfect, sunny but not too warm, when I pulled up. The cut is a somewhat unstable slope of cobbles and boulders of varying size, almost all with at least some fossils in them. To get up to the slope, you have to hop across a small ditch with running water. I have a good sampling of the common brachiopods from here, so I am looking for unusual fossils when I go now. I was very happy to quickly find a piece of trilobite as I started to search the rocks at the base of the hill. (I will put pics of everything I brought home in a response post) One interesting find that I was not able to bring home was this Linoproductus brachiopod with some shell preserved and a really pretty dendritic pattern on it- it was very delicate and firmly embedded in the middle of an ~80 lb boulder. I was able to stay for 4 hours, and I felt like I gave most of the site at least a quick look. I am very happy with what I found- I was able to check off many of the rarer things I was looking for, including shark teeth, a trilobite, cephalopod material, and a brachiopod with spines attached, as well as some nice crystallized brachiopods. I will post all of my finds below.

I’ve been air scribing this piece out and I figured it was a Mooreoceras. However, the ridge going up the front is something I haven’t seen on this species. Is it just squashed a bit? It’s a pointed oval in shape. The length is nearly 3 inches.

Found this cephalopod at Caesar Creek a month ago, just now got the chance to clean it up now that school is done. It's about 4.5 inches long and 1.5 inches wide. My best guess at ID is Cameroceras but if anyone thinks it may be something else please let me know. Looking at about 450 million years old. Before After

I've been cleaning up a few boxes with devonian fossils from the past few months and came around this nice little fellow. I cleaned him up and gave him a paraloid treatment to preserve the pyrite. It is a complete specimen of a Bactrites sp. from the Matagne shales ( Frasnian, late Devonian ) from Belgium, both phragmocone and body chamber are preserved. They are a little unusual, as the do not belong to the nautiloids as his first appearance might suggest but they have their own subclass and are considered to be the ancestors of the ammonids ( they have a ventral syphuncle like all the ammonoids ) Fragments of them often pop up from the shales, but I rarely find them complete. This one is going in the display cabinets

This could be my fossil of the day… but I would like to get your expert opinion please.

Back in May 2017, I brought back some nice fossil plates from Ohio, I believe Ordovician in age. First photo is plate 1. Next photo (of plate 1) shows a close-up of parts of the trilobite Isotelus, next photo - a nautiloid (unknown species), next photo shows valves of the brachiopod Strophomera, along with many bryozoan fossils. Next photo is a close-up of crinoids on plate 3. (Not much on plate 2). And last photo is of quite a few crinoids on plate 4.

Hey, I posted my trip to California from Washington yesterday. I have now looked through my rocks and noticed that one of these rocks are different from the rest. I took a picture of the Buchia Bivalve in the first image, to show that it has a different shape and markings than the bivalves I found there. If anyone can give me a genus that would be great. Is this another shell or something more? Thanks guys
-
Found this while searching the creeks located around my farm. I find a lot of bryozoans, brachiopods, crinoid stems and that’s about it. Never have found a fossil like this around here before, though I know Northern Kentucky has found orthocone fossils before. Interested in what you all think!

Hey guys, I am fairly certain that this is a straight-shelled nautiloid cephlapod but this one is different from others I find. I find a lot of fragments from cephlapods in Cincinnati with only a few segments. This one seems like the whole shell, though it is 7.5 centimeters in length. Also one side has a bunch of holes which I am curious about. Any more info on this specimen would be much appreciated. Found in a creek so it has probably been weathered a lot. These next pictures are the top and bottom, (i dont know why they are flipped to the left)
