I found this poking out of my horse corral, I think the first summer I was here. That was 2012 and we were in the middle of a severe drought. It was dry and dusty but made for good rock picking. I dug around for more of it with no luck. My farm is in southern Wisconsin, about 5 miles north of the Illinois border and about dead center on the east-west axis. We are on the eastern edge of the Driftless - the rugged western side of the state that was missed by most of the glacial ice sheets. Most of my rock is limestone (I think) from Ordovician seabeds. 440-490 million years old I think it might be an Othonyboceras. It's about 4 inches long and about the size of my wrist. One end is round and the other end widens and flattens out. I think the flat end was open and that's where the "squid" part was. There are some long, dark marks on the underside that may be from soft tissue like arms or tentacles? I find it interesting that the shell was cracked before it fossilized. I can post more pictures but I wasn't sure if my files were the right size.

Hi everyone, I'm not big on forums but I made an account here because I've got something.. weird and need answers. I wanted to email a professor or something but didn't really know how or if I would get an answer so I figured this would be a good start. Anyway, I was visiting Florida with family and my mom told me she found a weird spiral shell she thought I would like on the beach and gave me this: needless to say I was a bit alarmed. I don't know of any extant animal with a shell this shape and I can't imagine a fossil washing up on a beach like that. It doesn't look fossilized in the first place. If this isn't some kind of magical late surviving ammonoid or something it's probably something at least as strange. Oh also the inside is curved and covers the inside of the shell with a tiny hole at the bottom. What do you think I'm looking at here?

I was checking out a new Devonian spot and came across a section that contained a lot of deepwater marine species - cephalopods, very large clam internals, orthonoceras, etc. Didn't have much time at the site but I was scanning some large boulders and concretions up to 3 or 4 feet long and spotted this gem sitting on a boulder. It has nautiloid features but I'm not familiar with this fossil category so any observations or opinions will be much appreciated. This fossil is 14 centimeters long. As you can see this is a very distinctive and unusual fossil and it has just become one of my favorite Devonian finds since we started fossil collecting. This is the photo I snapped at the site today - I'll post a better image tomorrow. (see more pictures on Page 2 of this thread) I'm thinking maybe Cephalopod Goniatites (a Middle Devonian Nautiloid)? UPDATE! - 13.Sept.2013 - The consensus is that this is an ammonoid known as Agoniatites vanuxemi, which existed between 385.3 and 392 million years ago. It thought to be the only species of Agoniatites found in the Mahantango Formation. It is also rare to find this fossil in Pennsylvania.

I just wanna share this cuz I never found an endoceras this big before, which is kinda special and unique for me . I was out fossil hunting at the Humber river area here in Toronto with a good exposure back on Saturday and I came across this big phragmocone part sticking out of the bedrock. It was tiring having to dig it out. Siphuncle sticking out Dug out.

Hello everyone! At around at the end of August I started making frequent visits to Mimico creek in order to collect fossils before the next winter comes (hopefully it wouldn't be as cold like the previous one was), and also the other reason was because of the developments going on at the creek. I was fearing that they would eventually cover up all the exposures I know of. I made my way through the woods and shrubby areas to reach certain exposures.

Hi, I'm currently undertaking some fieldwork in south-east France, looking at Jurassic and Cretaceous carbonates, and I found a fossil that has me stumped. The fossil was found in a Berrisian (I think) rhythmite sequence within a limestone bed. The beds contained lots of other ammonites (of multiple species) and lots of belemnites too. The fossil is coiled and has prominent ridges spaced about 3cm apart, but otherwise the surface is quite flat. It has a strange, almost elongate shape. I'm not even sure whether this is an ammonite or nautiloid, let along a species for it. Any help would be greatly appreciated. Thanks

Here are all my unknowns from the past few months of collecting and snapping pics before joining the forum. Some are weathered, but any help identifying is greatly appreciated The first two are glen rose formation dino prints about 16 inches from heel to to toe. The third is a nautilus (eutrepoceras?) from central san antonio i extracted from a soft limestone boulder. Its about 9 inches across and the lower of the three well-defined sutures i think is eroded into a deeper curve than it would have originally had.

From the album: Lower Devonian
Unidentified nautiloid section Lower Devonian Kalkberg Formation Helderberg Group Schoharie, NY Dug this out of a quarry wall on an NYPS outing. Realized when I got home that the end piece might still be lying on the ground near where I found this. -
I've purchase this Nautiloid, that comes from the Moroccan Devonian. I know that belongs to the Clymenia family...But that's all! No idea of the exact strata or place from it belongs, or it's exact name. Can somebody help me?

Just had this photo sent to me for id. All I know is it is 7/8 of an inch wide, and was found somewhere in Texas. Looks like a cephalopod to me. Any help would be appreciated.

Stumped - Seed Pod? Rhyncholite? Chiton? Late Cretaceous New Jersey

I found these in the latest Maastrichtian, uppermost New Egypt fm. of NJ. Both pieces were basically found together which leads me to believe they are somehow related. I have never found anything else like it although I could have easily missed other similar objects since they are small and somewhat nondescript. The preservation reminds me of invert steinkerns found in the same layer. I thought these might possibly be pieces of some larger invert, but I have no idea what. And they really do look like 2 discrete structures instead of pieces of something larger. The local ammonite/invert expert of the Atlantic Coastal Plain, Ralph Johnson, was stumped as well, but suggested that they might be rhyncholites. I can definitely see a little resemblance to rhyncholites, but I would like to hear any and all opinions. Eutrophoceras is fairly common in this formation so it would make sense that these might be from a nautiloid. But please share any ideas and opinions on these that you might have! http://www.youtube.com/watch?v=g4JZWcsHflY -
I spotted this thing from a moving car in a forest preserve in Winnebago Co, northern IL. I unfortunately do not have much info regarding its origin, except that all of the bedrock in this area is Ordovician, and most of it is Galena and Platteville groups. I assume it's from a nearby quarry. I think it's a HUGE straight-shelled nautiloid, but I'd like some more opinions. If my guess is right though, how long do you suppose it might have been in its entirety?

I found these and many more in creek areas in two sites here in San Antonio. I love that my greatest finds have been here in my hometown of San Antonio. While Austin is my main source for a grand looking Exogyra Ponderosa, would you believe that its equal in size and shape is down here in San Antonio. I don't know which variety but the striations are very different and the horn curl is equally different at times. I will post some more soon and of Austin. Thank you for looking.
