Hello everyone, Some time ago I was talking about a gastropod fossil with an individual online who thought that it was an ammonite, During this conversation one thing was brought up that I have wondered about for a long time but have not actually been able to answer, and that is what exactly do we consider an ammonite? I have always thought that ammonites are the cephalopods with an external shell containing complex sutures which occur throughout the Mesozoic, but people have pointed out that certain sites talk about ammonites going back to the Devonian. I have always thought t

Last Saturday we went on a new fieldtrip on one of our favorite hunting spots for Devonian fossils. Not a lot of fossils were found and the only large goniatite, although pretty at first sight turned out to be a nightmare to prep with little to no preservation further down in the nodule. On the other hand we had verry sunny day with nice views over the area and the first flowers taking advantage of the sunlight on the older scree piles. We also brought home a few small nodules with tornoceras fossils , they will take a while to prepp before we will see if they were worthwhile.

Hi all, Last part of my finds of the year. In autumn, between lockdown 1 & and lockdown 2, we managed another 3 days hunts. First day was spent in our usual trilobites spot, which happened to be on the way to our main destination this time. You have already seen in my first part some of the trilos we did find on that day, which was a rather good one for me. Day two was spent in Nanteuil quarry not far from Niort. the quarry got mostly bajocian and aalenian. the aalenian is on the "ground of the quarry" and was mostly drown at that time of year. So Bajocian- 3 replies

Taking advantage of my time spent home, I finally got a couple of glass display cases to showcase fossil specimens from my collection. Finding ones that were affordable and blended with the style of our home, was challenge, and I took my time choosing. Despite a bit of criticism I receive from some of my fossil collecting friends, I am a generalist collector who doesn't specialize in anything. Having said that, my collection does feature some rare faunas; Devonian and Cretaceous bivalves, Lower and Middle Devonian brachiopods and gastropods, Cretaceous vertebrates, etc. The focus is largely on

So I found this fossil skull... Kidding! Anyway, back digging in the needmore formation outside Winchester VA and I’ve started finding a lot (like in one small part of the exposure, a whole lot) of these sorts of shells. Initial thought was some kind of ammonite. Searched for mid Devonian and got agoniatites vanuxemi but I don’t get any hits in this formation/location. Still looks right though, although I guess it could be some kind of gastropod? Mostly a little over 5 cm at the largest. Also, they’re generally the same color/consistency, save for this one very colorful specimen (very dis

Identification for a large variety of different fossils (Georgian Bay Formation)
Emthegem posted a topic in Fossil ID
Hello all! So I've been looking through my collection and noticed a bunch of fossils that I haven't yet identified yet. Some of them are quite peculiar, as I've never seen some of them until now. This'll be a long post with 12 different fossils in need of a name so brace yourselves hahah: All fossils found in Toronto creeks - Ordovician Era - Georgian Bay Formation 1. I thought this was the typical Treptoceras crebriseptum that I always find at my local creek, but when I cracked it out from the matrix I noticed it was perfectly smooth. Maybe its the living ch -
Hello! Just wanted to show off some VERY nice fossils (by our standards) I found this past weekend in Etobicoke creek right around the border of Mississauga/Toronto! Me and my dad decided to get back in the groove for some fossil hunting and spent a while biking off road until we came across the mother-of-all rock deposits (by Toronto standards). I posted a couple pictures of the big/best finds below, sorry I didn't have a ruler on me for reference so Canadian currency will have to do for those not from Canada: *To make the lives of those outside of Canada slightly

Belemnite "squid" with interesting bore hole found in NJ creek
CityDweller posted a topic in Fossil Hunting Trips
Hi TFF, I recently was in New Jersey and stopped by a creek where I found this. This is a part of a belemnite, an extinct order of squid-like cephalopods that existed from the Late Triassic to Late Cretaceous (~214-80 mya); these are common to the NJ area and the NE USA (as well as all over the world). The cone (rostrum) you are looking at was inside the animal and served as part of an internal skeleton-like structure; it also served as a counter-weight while moving in the water. On the cross-section (C & D), notice the radial symmetry which sprouts from a central a- 11 replies

Today on day 2, I spent about six hours in the on and off rain, near Lawrenceburg, Indiana collecting Ordovician fossils. I found numerous trilobite parts, but nothing complete. Things that believe are parts of trilobites- "Isotelus" fragments. These two pieces were on a very large block that was not feasible to try and move. I figured that I would try and get them out, but unfortunately, I was not successful . Many Cephalopods – Brachiopods- "Platystrophia"

This Monday we went on the last fieldtrip for this year, the weather forcast was cold but sunny so a good excuse to get out. We took te dog along and went to the quarry, A lonely excavator was operating in the far end of the pit, I went for a quick chat to let him know we were prospecting in the other side of the quarry and to ask if it was no issue for him. The fossil rich deposits had'nt moved since our last visit, but we still did find a few cephalopods. Natalie found a very promising one, the goniatite looks to be preserved completely in white calcite, I cant wait to get tha

Cephalopods from Bois Blanc and Onondaga formations
dinosaur man posted a topic in Questions & Answers
Hi I was wondering are there any Cephalopods in the Bois Blanc and Onondaga formations? Thanks! @Kane -
I bought a new old cabinet last winter and spent several months filling it with newly labeled specimens, most of them now stored in jewelry boxes. I took photos of it to show Tim, Fossildude19 and he suggested I post them in the Members Collections section. I followed his suggestion. The collection started in 2011 with a few fossil purchases off a well known public auction site. By the early spring of 2012 I was collecting in the field and the vast majority of my collection was self collected in that manner from sites, primarily in the Northeast and Ohio Valley as well as ones collected on tri

Greetings from Texas! So I have posted previously about my hunt to find all the species of Echinoids in Texas. Well, I am also on the same fossil quest for all the ammonites, nautiloids, baculites, turrilites and belemnites I can find as well! When looking for one, you might as well look for the other! So I thought I'd start a post of my ongoing hunt for all the cephalopods. I'll start with some of my finds from the recent past and I am still working on my identifications, so please do assist if you notice the wrong ID! Thanks and also post some of your finds! I'd love to see 'em!

Michelenoceras ssp. and portion of Tornoceras uniangulare Devonian Hamburg, NY Found 2019 -
Last Autumn, I took a side trip to Graf, Iowa in search of it's "elusive" cephalopods. Fortunately for me, a large piece of rock had released itself from the overhanging cliff and I proceeded to use my sledge hammer on it until broken into eight 50 lb pieces. This then was loaded into my truck without further exploration as I knew, each chunk contained maybe 50 cephalopods within it. These chunks of matrix were to provide me with a little winter entertainment while the landscape of Minnesota remained white. Two weeks ago I began splitting these boulders, looking for the treasure

Hi all, Here are some fossils I found at this summer in Carniol, and I would like to know what they are. If the species can be said that would be fantastic. So, the fossils are all from Carniol, France. They are from the "Gargasian", of the Aptian stage of the Cretaceous, some 120'000 years old. Looks like they're all pyrite-replaced. I believe they're some kind of cephalopods, but I'm really not sure. What are your thoughts? Thanks in advance! Max

Monday was Labor Day, a holiday. I was going to be off work and home alone. I woke up early for a day off really motivated to get up and get out to the North Sulfur River (NSR), but I was feeling a bit lazy. I didn’t want to wear myself out too much. I am on call all week and being worn out isn’t a good way to start being on call if you have to stay up all night working. I had not been out to the NSR since June, because I nearly did myself in last trip with heat exhaustion. I had plenty of fluids, but the 100 degree heat with no shade was too much for me. Anyway, the weather on Monday was

Hi all, Here is one of the Aconoceras nisus ammonites I found in Carniol, prepped. Now unfortunately the center is gone Luckily... it has some incredible sutures! They are very nicely visible, and give the ammonite a really cool look IMO. The real reason for the sutures to be so clear is actually because there is still a bit of clay in between the suture lines. So to be perfectly honest, that means that the prep isn't 100% complete. But I'm purposefully gonna leave it as it is, because this way the wonderful really stand out. Pyrite ammonite Ac

Found this that I believe is a cephalopod today at a devonian spot with imported material, I haven't seen a cephalopod with a bulbed tip before so I am not sure if it's some sort of pathology of a species or it's own species.

I have something of a cephalopod hash plate from the Britton Formation in Collin County Texas that I am working on. I don’t have great tools and so I’m prepping this completely manually, by hand. It has a layer of pyrite that is pretty tough to work with by hand. I am wondering, could I use Iron Out to soften or remove the pyrite without doing harm to the fossils or the cohesiveness of the plate? If so what would be the best way and dilution to use it at? These are pics of the little plate. I consider this the bottom. You can see the thin gray layer here an

Here is an entertaining article about the history of cephalopods that has really nice illustrations of what they may have looked like. It also points out why soft tissue fossils are nearly nonexistent. A tidbit: fossils once were thought to grow in the rocks. http://www.eartharchives.org/articles/500-million-years-of-cephalopod-fossils/
