  1. Had a mega trip to Dorset this weekend, finally found a couple of fairly complete nautilus, how would you prep this? Not done much, have an electric scribe and elbow grease..
  2. CWS

    Bite mark??

    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.
  3. 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!

    Cephalopod Shell Color!

    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, bu
  5. 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:

    Baby ammonite or possibly a Nautilus

    Found at runswick bay.. very small but doesn’t look like an ammonite to me… but I know nothing !!!
  7. 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.
  8. 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

    Nautilus ID and bite mark?

    I preped this nautilus fossil recently, Wondering if the damage on the shell was caused by predation? And is it Cenoceras sp.? Thanks Information about this: location:Gard,France age: Jurassic

    Nautilus Chamber? from Al Ain

    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)

    Nautilus pompilius

    I've been taking a drawing course over the last few months, learning to do portraits of people and animals, but I've been neglecting the fossils. So I figured it was about time to do at least a recent shell. I've also been experimenting with pastels, so it's colorful this time instead of just black & white.

    Nautilus pompilius

    From the album: Sketches

    A recent shell from the Pacific Ocean. Soft pastels.
  13. Mochaccino

    What is this shell?

    Seller lists this as a pyritized nautilus/cephalopod from the devonian, but no other info. Any idea what this could be? A belemnite phragmocone maybe? Thanks.

    Nautilus fossil?

    Is this a nautilus fossil?I don't have any informations about it,I guess it's from Madagascar? Thanks everyone
  15. Hi everyone, Last week after getting lots of recommendations from people I spend a couple of days at Cap Blanc Nez in France to look for some fossils. And while it wasn't to most bountyfull hunt I did have a lot of fun and I was very pleased with the little finds that I managed to do. We had very nice weather, it was sunny and the temperature was just perfect for fossil hunting, and the cliffs and beach (and landscape overall) were absolutely stunning. The fossils in Cap Blanc Nez date back to the Cretaceous and there are deposits from the Turonian, Cenoma

    Hi i found this nautilus fossil 25 km west of Riyadh. It was a surface fossil and I don’t know when this lived. the geological period is middle late jurrasic but I would like to narrow that down a bit what species is this thanks

  18. Yesterday I somewhat unexpectedly ended up with a day off of work, and as it's too hot to enjoy hiking, I decided it was time to hit up my favorite exposure of the Fayetteville Shale. I found myself thinking on my way out, I've picked this place pretty clean, I don't think I'll find too much. Luckily for me though, the -20F freeze and extremely wet spring we've had did a nice job of eroding the shale. Almost as soon as I got into the creek, I saw a pickerel frog tucked away in a little hole. Not too much further, I hit the beginning of the exposed shale. The bed of
  19. I haven't been collecting from the Lias of Dorset or Somerset (in the UK) for a couple of years, for various reasons, obviously Covid being a major one over the last year. I'd begun to think I'd not really be able to go much again, but then we moved to Somerset, close to many exposures of material from the lower Lias (Hettangian, approx 200m years ago). So these days, I'm able to walk on the beaches every day. Living the dream! So far I've only found two small icthyosaur vertebra, but ammonites and bivalves have been a little more forthcoming. Here's a few photos of so
  20. Hey everyone, I just posted a video where i share my best nautilus fossil at the end. This was found on the Yorkshire Coast and is pretty rare to find a Nautilus. It's the only near complete one i've found pretty much

    Two Texas DFW Cretaceous Nautilus

    When I was visiting my parents for Christmas, there was a surprise for me in my favorite local creek bed, and it wasn't just how cold the water was! I've found plenty of ammos there, but these are my first two nautilus. I tried to find out what they are, but I pretty much got redirected to ammo IDs. I was also wondering if it's worth buying the HGMS ID books. I'm curious, but don't really want to spend the money. These were found in a marl layer, but I'm not really sure which one. Grayson Marl I believe. Found in Tarrant County. Are they cymatoceras? Cracked one is about 2" diameter,

    Fossil Nautilus?

    Hi there - Been following this forum for years now but this is my first time posting! Figured I should finally try to figure out what this mystery fossil is that I have... Years ago - probably 10 years ago at this point - I found this fossil washed up on the beach at Bald Head Island NC. Because of its markings, I assumed it was likely a nautilus, but everything I found online or in fossil books of NC looked dissimilar from this particular piece. So, I'll ask you all - what do you think it is? Am I right to think it's a nautilus of some kind, or perhaps something e
