Hello, everyone! Below are a few finds from the North Sulphur River and Post Oak Creek, and I’d love to get some help with identification. The ruler is in centimeters. 1. This first picture includes two mammal teeth (top two)(fossilized or no?), ???, and a small bone that appears to be fossilized. these were found at Post Oak Creek. 2. This bone was found at the North Sulphur River. 3. Nautilus found at NSR. Could anyone help with identifying the species? 4. Jaw fragment? Found at NSR. 5. Coprolite? It appears to have fragments of bone(?) in it. Found at NSR. 6. I found this tooth at NSR a while back, but someone recently IDed it as Latoplatecarpus (mosasaur). I can’t find too much literature on Latoplatecarpus; could anyone give me more information on this tooth and the animal it comes from? Thank you!

I had to stop by a work clients construction site today (he builds houses), a mere 3-4 miles from where I live. They had just dug trenches for the waterlines, so I glanced around..Lo and behold, I found the biggest Cymatoceras nautiloid I’ve ever found. Fat Albert must have eaten everything else on the surrounding acre, because I barely found anything else..LOL! I was pretty thrilled. It’s over 11.5 pounds. A friend asked me if it was an Eopachydiscus..nope, it’s a Tarrant county Grayson formation nautiloid!

Hello, I managed to obtain this nautilus from the internet. The former owner told me she got it 60 years ago from an employee from Shell. He took it from the desert in Oman. He told her, there where many more fossils to find there, but that the accesibility was very complicated. She could'nt tell me the age from the deposits. So I tried to google some information. At first, looking at the pictures I thought about a jurassic nautilus. But the more I am diving in to search the possibilities and the fact that it is quite slender for a nautilus I'm leaning towards a Eocene nautilus. Deltoidonautilus would be a possibility. It is 27 cm. Can anyone help me with the ID, or pherhaps put me on a good path to find it? Greetings Walter

Grayson formation nautiloids- Tarrant County TX
Shaun-DFW Fossils posted a topic in Member Collections
I would love to learn from some of you regarding what species of nautiloids these are (maybe multiple species). They’re different than the larger ones I find more often in similar areas and I like the pattern detail visible on some of them. They almost always have a very distinct curve at the outer edge. These are mostly from 2 spots in burleson TX. The unusual nautiloid with lots of details visible and crystallized (looks brown in the photo) on the inside was from a different spot (maybe Fort Worth formation?) where I find mortoniceras ammonites.- 19 replies

I previously posted my woodbine ammonite collection (calycoceras/conlinoceras). I’ve since sliced 2-3 that were without hope of reflecting external beauty, for lack of a better description as to why. Haha..I find a lot of nautiloids where I live due to proximity to Fort Worth/Grayson formations. Oftentimes, the spots that have mortoniceras ammonites also have occasional nautiloids. I exposed a small amount of crystallization while removing this nautilus, so I experimented with slicing this one. I’m glad I did! What a beauty. I have plenty of whole specimens (some QUITE large) that will stay whole, but this one is unique!

Hello Again. Today I would like help with what I think is called a concretion that I found in Llantwit Major, South Wales on the beach on Saturday 16th Sept 23. There is something inside like a Nautilus, I think. I had a go at it with a rotating Dremel and a chisel and hammer, but I scratched the fossil, so I stopped. I have bought a Dremel 290 Engraver that is reciprocating, but I haven't used it yet. I wanted to get some advise first. So if you know what this is, I would love to hear from you. I also nearly broke my back retrieving this, so I want to get in right.

Hi, We are just trying to figure out if this is a real fossil or not. It was given to us by an elderly neighbor with no backstory. Thank you so much for your help!

When I picked up this partial, larger wave battered nautilus at Whitby I didnt have much hope for it. Nautilus are rare from the Yorkshire Coast, this is from the upper lias. I gave it to my friend Malcom who has done a fantastic job removing the incomplete outerwhorls and has left me with a beautifully preserved middle. It even has some of the outerwhorl as a lovely display stand.

MiniP had to pick a topic for a science presentation at school. We chatted about volcanoes, weather and such as potential ideas. Eventually, she settled on the subject of Ammonites and Nautilus (brings a tear to he ol' dads eye )..which morphed into a story of survival. She worked hard on this project and seemed to really enjoy it. When it came to the actual presentation, she killed it! She passed around Ammonites from @nala, @Uncle Siphuncle, @old dead things and @Ludwigia to show examples of variation, while comparing Nautilus fossils to a modern Nautilus shell to show how it really didn't change much. She theorized of why the Nautilus may have survived the impact/KT boundary, but the ammonites didn't, using ideas of suture shape and water depth. Towards the end, the kids got to ask questions. How she handled it made me proud...she answered them all with confidence, which told me she was really understanding her project. After she wrangled up all her specimens, she passed out an activity to her classmates...a create and color packet... ...for them to work on as a class and discuss. I left with a big smile on my face ...figured I would take a minute to share it here... ...Nautilus: a story of survival. (insert nautilus emoticon here)

Found this critter in what I believe to be the Brush Creek Limestone. It is Carboniferous (Pennsylvanian), Glenshaw Formation, and looks like a nautilus to me, so I'd guess Solenochilus. Thanks for the help.

My aim for the last year or so has been to find a Nautilus on the jurassic coast in Dorset Uk. On my last visit I did find a few chunks, that feel like I am barking up the right tree! I know the first photo is of just a section, but am I looking at the right sort of thing to hit my Nautilus goal? It is approximately 15inches across. And the second image is a reverse side which has been heavily eroded but the shell is protruding around the entire outer edge of the stone. If so, what would anyone suggest regarding prepping these and even if they are suitable/ worth attempting? I only have basic tools i.e. my dremel with fossil tips from zoic palaeo, and the standard pointy tools for manual picking, etc 20221130_140810.mp4

Picked this up in Dorset, I've only cleaned in fresh water and that hole appeared in the keel of the Nautilus. Its very well defined, what do you think, possible tooth damage? Appreciate your thoughts.

Hello, found what I think are nautiloids and brachiopods. I found the rock in a stream and I can't say what limestone (maybe brush creek or pine creek), but the area is Glenshaw Formation in northern Allegheny County, Pennsylvania. It's quite difficult for me to get good pictures, let alone good pictures with scale, so I'll tell you that the first two pictures are 2 cm (same organism), the second is 5.5 cm and the largest Nautilus in the last pictures is about 6 cm. All information is appreciated, thanks!

Hello all! Recently I have been obsessed with cephalopods and realized there is a real lack of reconstructions of the color patterns on extinct nautiloids and ammonites! This led me to compile a list of known fossil color patterns on cephalopods. After a year of on and off research, I found about 90 species of cephalopods retaining official or undescribed, original patterning on their shells. These are the first 15 species on my list. The color markings are based both on descriptions and photographs of the fossil material. The shades of the markings are based on the fossils, but also inferred. I Hope you will appreciate my work!

Hello, Here are three fossils whose provenance is unknown...but likely somewhere in the US, and possibly Colorado. Does anyone have ideas for more specific IDs and possible provenances for them? Thanks. The first is what appears to be an echinoid, Eupatangus maybe? The second to me looks like a nautiloid steinkern/internal cast: Third is this plate of starfish:

I recently bought this on online with no provenance, from a buyer with 1 feedback and some rubbish photos. To be honest I figured either nothing would turn up or itd be concrete, which is what I was hoping for (needed a doorstop) 'Unfortunately', it appears to be real, and now I'm interested. I'd appreciate any input. I've tried to show the shell patterns in some of the photos, as well as other fossils in the matrix base.

Impromptu Construction Site Hunt. Grayson Marl and Pawpaw Formation
Mikrogeophagus posted a topic in Fossil ID
Following a refreshing swim at the lake with a few friends over the weekend, I decided to take a spur-of-the-moment stop at a construction site I happened to be driving by. The sun was setting, cooling the area and finally making it hospitable despite the recent heat wave. I was not familiar with the exact geology of where I was, but with only an hour and a half of daylight left I decided to not waste too much time and immediately began scouring the dirt. I quickly noticed that the ground was composed of two distinct formations. The higher layer was a grey limestone while the layer underneath was bright red and filled with a wide range of greens and yellows among other colors. It was only until I got home that I realized these were the Grayson Marl (/Mainstreet limestone?) and Pawpaw formation respectively. My first find was an unexpected, but welcome one. Coming from the grey rock, I noticed a rounded form that stood out against the jagged terrain surrounding it. After prying it out, I was surprised to find that it was indeed a large nautilus (A). Not too long after, I found a couple more that were in slightly worse condition. Continuing my search in the greyish area led me to later find a chunk of Mariella heteromorph ammonite (B) as well. I particularly like this specimen as it is interesting to compare it with my Mariella micromorphs from the Waco Pit and other locations. I also managed to snag a few pretty little brachiopods (C). I have a really difficult time differentiating between brachiopods so my ID for them is a bit iffy, but for now I'll go with Kingena wacoensis. The cool thing about this site is the fact that it sits on the border of two very distinct formations. As a result, one can find a wide variety of fossil life. The rest of the things I brought home from this trip were found in the red Pawpaw formation. For whatever reason, Texas loves to produce pyritized micromorphs. I was surprised to come across a multitude of ammonite genera with that classic bronze coloration I've come to be all too familiar with. I found a few un-pictured fragments of Mariella and other ammonite pieces. I was also able to pocket a few chunks of my favorite ammonite, Engonoceras (D). I didn't really capture its beauty well on camera, but something about the way light bounces off of the broad reflective shell is mesmerizing. I hope to one day come across a complete one. To round off the hunt, I found one last slightly enigmatic specimen (E) that came out of the Pawpaw. Its a big rock with lots of holes running in and out of it. The holes are covered with countless tiny divots. My guess is they are what's left of some crustacean burrows as they bear some resemblance to the poopy burrows I have seen elsewhere online. Some of the burrows have crystallization. Here are the finds: A). A large nautiloid and a smaller one coming from the Grayson Marl. I believe them both to be Cymatoceras. There is some extra matrix on the outside that I am debating on chiseling off. B). A fragment of Mariella heteromorph ammonite from the Grayson Marl. C). Kingena wacoensis? from the Grayson Marl. They have some nice detail! D). Pyritized Engonoceras fragments from the Pawpaw Formation. E). Crab burrows from the Pawpaw? All in all, I'm glad I made a quick stop at this particular site. It's a pretty interesting place with a wide variety of things to be found in a couple of formations I have only just begun to explore. I will likely make another trip there in the future! Thanks for reading!- 7 replies

Hello again. I am currently in Al Ain (an Emirate of the United Arab Emirates), my absolute favourite place to be! I have found many fossils here, but I was quite excited when I picked this one up today. I think it's a nautilus chamber. At the same location there are tousands of nummulites, many shell steinkerns, and some urchin fossils (schizaster along with some others). I would like some confirmation! (The square is 5cm by 5cm)
