@Raggedy Man and his "phantom" wife, Laura, came up to fossil hunt for her 31st Birthday and what a hunt it was! I was busy the first day they were here with my little Airbnb Whispering Winds checking people in and out but they had a wonderful day hunting and Paul found a Bumastis trilobite - they are trilobite hunters. He will have to post his pictures. :-) On Saturday I had invited new fossil friend, Todd, from the Twin Cities to hunt with us. He had come on a paid hunt earlier (he left with 2 5 gallon pails of fossils that very long fossil hunting day) and we had bonded and this was a good opportunity for him to get some real fossil hunting done. I had heard about the "mythical" Seven Springs down a favorite sometimes dry wash and was on a mission. So off we went to hunt Orodovician fossils and Seven Springs! It was a lovely fall day in Minnesota in the 60s with leaves slowly turning brilliant colors and falling to cover the floor of the wash. The first part of the wash was not particularly fossiliferous but we had perhaps a mile or two to go to Seven Springs, so I was warning Todd not to pick up too many fossils. And yes that big plate was beautiful, but too heavy to carry out - that is what hammers are for... :-) The day was beautiful and each corner drew us around another. Paul and Laura had gone up the wash. And there were plates that just weren't going to come back with us. But the siren's call of more fossils to be found just kept us going... But this worn Fisherite showing the side structure was one I just had to have! We rounded one bend to see wild morning glories blooming against the gleaming white rocks of the Galena Formation. We were back in pretty far and hit a very fossilierous wall. I was on a mission and just had to keep going to find Seven Springs - was it real or not? Todd was happy to be left there. :-) The next corner of the wash called to me, and the next, and the next... I ran across the tracks of a large white tail and knew I must be near water. Finally! The first of Seven Springs! My mission had paid off! Seven Springs! So serene and beautiful! I had dropped my backpack back by Todd and so fossil hunting my way back was only what I could stuff into my fly fishing vest. When I finally got back, Paul and Laura had hiked down the wash to see what the old folks were up too. :-) Continued...

From the album: Cephalopods
Aturia Augustata is an Eocene Nautiloid from Lincoln Creek Formation, Grays Harbor County, WA, USA . Sutures (or suture lines) are visible as a series of narrow wavy lines on the surface of the shell, and they appear where each septum contacts the wall of the outer shell. The sutures of the nautiloids are simple in shape, being either straight or slightly curved. This is different from the "zigzag" sutures of the goniatites and the highly complex sutures of the ammonites.-

Cephalopods and a few Questions for thee experts.
fossilized6s posted a topic in Fossil Hunting Trips
I drove about 4hrs west to find trilobites, came home with cephs. I did happen to find some pretty neat trilobites, but they need prepping, so i won't post them. Hunting more for trilobites this year i come across a lot of other fossils and i find it exceedingly hard to leave a neat looking cephalopod behind, so i grab em. Most of these will be left outside, but some are nice enough for display. Here are some nice ones. I love the contrast and size on this piece. The isotelus cephalon and worm burrows don't hurt either. Continued....- 15 replies

B. americana is the Delaware State Fossil. They swam in huge schools and were the base of the food chain in the shallow sea that covered Delaware and New Jersey at the time. This one was found by a surface scan of the loose fossils at the site. They are very common in broken bits and pieces. A whole piece will have a point at the tip and a conically hollow section, the rostrum, at the other end. Whole ones are very rare. This one is nice, however, because it still has its original texture.

I got this a few years back in Canaan valley (if memory serves) West Virginia before With a bunch of other fossils. I bought it, as this was before I had learned that you could actually legally hunt fossils yourself (if I had known, that valley would have been scoured for fossils, as its geology is apparently amazing). I assume this was from the area, although this could be incorrect. This one caught my eye because of its curvature, is this the way it was when it was alive or is it just disarticulated septa? Is it possible to get a close ID on this orthocerid?

Hey!! Are these cephalopods? More specifically Dawsonoceras? Found in Vaughn Ontario near a stormwater pond - I have a feeling it's from a local quary since this pond is a man made structure. TIA!!

Hi folks, Rocky again. We had a nice shower this eve., walked the yellow shale plowed area and found these tidbits rinsed off. The longer one is the best orthoceras segment that I've found here so far. Also found the delicate little arrowhead. But as usual, it is broken. This is the first rain since the tilling. I'm hopeful (and confident) that more will pop up after several more rains and another tilling ... or 2. Kind regards.

Hi all, It's been a few years since I've posted here, but I'm hoping to bring some order to my fossil collection and prep some specimens for display. I've tried to glean info from other threads in this sub-forum, but am still trying to figure out how best to approach preserving/restoring Ordovician fossils. As a for instance, how would others approach this rock? It's a piece from southeastern Indiana and contains what I've tentatively identified as Tentaculites sterlingensis and some Flexicalymene pieces parts. Is there any way to make the Tentaculites pop out a little more and clean it up without breaking up the actual fossils? The rock is about the size of my hand. I like how others have given that glossy dark finish to Flexicalymene trilobites; can that be done here? Thanks for any tips you have and I apologize if this is not the right place to post this particular question. -Andrew

From the album: WhodamanHD's Fossil collection.
This was the first fossil in my collection, yet the age, formation, species, and place of origin are all unknown to me. I assume it was from Madagascar. Bought for me as a present.-

As I wade through the boxes of fossils I collected as a kid and try to make heads or tails of what everything is, where it was collected, and whether it is worth keeping or giving away, I've hit a road block with cephalopods. It seems cephalopod identification hinges largely on internal features that are not always accessible/preserved. I'm trying to figure out what I can and cannot identify and also what I am trying to look for. I've got two examples below; the smaller one is from Ripley County Indiana and is either from the Liberty or Waynesville Formation (I believe) of the Richmondian stage. Looking at it, I was thinking the small circle visible on both the anterior and posterior end is the siphuncle. If this is true, it looks to be ventral which would make this Cameroceras? Am I on the right track and can I get it down to species possibly? The second, larger fossil is from Franklin County Indiana and is also from either the Waynesville or Liberty Formations of the Richmondian. Based on the shape, it seems like this is an Oncocerid cephalopod and I'm torn between Diestoceras and Beloitoceras. Once again, am I in the right ballpark and can this be narrowed down any more given the condition of the fossils? I'm interesting in learning what features everyone is looking at in identifying cephalopods and what kind of preservation is needed to get to at least the genus level so I can apply the approach my other cephalopod fossils. Thanks for any help you can provide! -Andrew

Hello- We found three unidentified fossils by a lake bed several years ago. It appears to be a cephalopod of some kind. The animal has 'plates' instead of 'ridges' though. The longest fossil measures at 7". Can you please help with the identification? Thank you!

Found some amazing stuff today with @Kane @ischua @DevonianDigger @Fossildude19 and @drobare We hauled some serious rock and had somewhat of an assembly line going with splitting and processing the pieces. It was a really solid day all around and everyone walked away with some sweet finds. The following is a sample of some of the cool stuff I've found. The rest is packed away. The first is a large cephalon and will look good despite not having a body and then there's a Spyroceras cephalopod that might benefit from some very gentle prep work. I really like cephalopods because of all the neat chambers they contain.

I found this possible cephalopod in the Upper Pennsylvanian Graham Formation at the Lost Creek dam Spillway near Jacksboro Texas. It is 30mm long with a round profile 12mm across. The arrow in the picture below points to a portion of the inside layer that is broken away from the internal mold. The arrows in the picture below point to two more layers outside of the first. Here is a fourth layer on the outside of the others. Here you can see the layers on the blunt end This is the pointy end The ridges in picture below are the only hint of any ornamentation. At first I thought it was one of the enigmatic burrows we find there but they don't have all these layers or these ridges going around the shell just occasional linear grooved linings.

This coprolite is from a marine creature that swam in the Jurassic seas that once covered this parts of England. The dark inclusions that can be seen on the surface are Onychites (cephalopod hooks). In April 2016, the University of Minnesota X-ray Computed Tomography Lab scanned the specimen using a X5000 high resolution microCT system with a twin head 225 kV x-ray source and a Dexela area detector (3073 x 3889 pixels). Many of the images shown here are of individual 3D elements/features within the coprolite that were separated/isolated using Blob3D. The taxonomic classification given is for the inclusions, not the coprolite. Aside from the hooks, it is hard to definitively identify the inclusions without damage to the coprolite. The following is a list of inclusions: 241 hooks of various sizes that are at least 75% intact. 200+ plate-like fragments of various sizes (likely similar to the surface nacre). 19 ellipsoidal structures, possibly forams or parasite eggs. 2 unidentified long, straight conical structures joined at wide end (A) 1 long rod-like structure with a bulbous end (B) 1 unidentified mass that looks like it was the attachment point for 5 rod-like structures (C) 1 1ong cylindrical (rod) structure that tapers in the center. The center density is much lower than the outer shell (D) 1 irregular structure that looks I originally thought might be an ink sack or buccal mass, but the size is wrong. Experta think it is more likely foraminifera (E) 1 irregular structure, possibly a statolith (F) Acknowledgements: Thank you to Neale Monks and Christian Klug for providing input.

Hi, I came across this site last week and though it might be a good place to help me identify my latest find. While excavating for an addition on my house, I found these two fossils at about the same time in the same location. The one on the right is a trilobite, however the one on the left is the fossil I’m having trouble identifying. My property is located in southwest Michigan, in an area known for glacial deposits, so it makes it a bit challenging to determine what period the fossil is from since it may have traveled many miles before it was deposited. I have found many fossils on the property (almost every time I dig), but this one has me somewhat stumped. I’m pretty sure the substrate is marshall sandstone. In one of the photos looking at the center axis, it appears to have been agateized. Thanks for your help.

Found this fossil in a creek in middle Tennessee. I originally thought it was a crinoid column, until user ynot pointed out that it was more than likely an orthocone shell. Judging from where it was found, it seems to be from the Ordovician. So now my question is: what species of orthocone do you think it is? Note the size (5 1/2" long, 2" wide) and the segmented pattern. Thanks for the help!

Hi there! We're looking for an ID/info on a fossil my husband's cousin found in northern Michigan - Lake Michigan area (Traverse City). Info on the rarity of this specimen is also appreciated, for excitement sake. So far we have been told some type of cephalopod, though we can't seem to find any exact ID or photos of anything exactly like it. Photo and video attached. Thank you in advance!! IMG_9899.MOV

About a month or so ago, I had a few hours to kill and decided on a whim to go search for the Lecthaylus gregarius in Blue Island, Illinois. I walked down to the river and found the Lockport shale which was really fun and easy to split apart, but all I came across were lots of plates of worms like this one: I wasn't even sure if these were Silurian annelids. In the end, I was unsuccessful in finding Lecthaylus gregarius, however I did find these fossils: If anyone has more info on genus types, etc. would be greatly appreciated!

I know nothing of the real provenance of this specimen. It was found near a house here in western Missouri where everything is either Pennsylvanian or Quarternary--there is no igneous rock in the area. I have three questions about it. First, is it a fossil or is it modern? Second, is the rock on which the specimen rests igneous? Third, is it a forgery—something made for a novelty shop? Any answers or comments you can give will be appreciated. Russ
