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

Day Two ; Locality One (or Six if you include Day One) Black Sahara, South of Erfoud 20th February 2019 Well this is where things really get interesting, so stick with this thread as there are dozens of photos of fossils coming up. Looks at the tags if you want clues. I was up bright and early and wandered out at about 7 am to watch the sun rise over the still mighty Erg Chebbi dunes. And as night's candles were burnt out and jocund day stood tiptoe over the misty duney tops, the chaps came to join me and managed lots of photos. Here's one, if you w

How rare are phragmocones from cephlapods? Are they something you need to get into a quarry to find, or can you recover them out of roadcuts? This is for the Midwest, like Illinois, Wisconsin etc.

Final Round of Real vs. Fake
Lucid_Bot posted a topic in Is It Real? How to Recognize Fossil Fabrications
This is actually quite enjoyable finding out which fossils are real and fake. First pic we have a fossil flower stamen from the Green River Formation in Utah. The second piece was quite cheap, but it's from Morocco (Anti-Atlas Mtns.) and it seemed odd to me that the bottom Orthoceras has the same pattern as the matrix below it. But perhaps you have an explanation for that. The third piece is a Ginkgo leaf from the Sentinel Butte Formation of North Dakota. The final piece is a Juvenile Megalodon tooth from Pungo River Formation of North Carolina. Thanks again to everyone who's helped out, I'm -
Graf, Iowa Orthocone Shell remnant or epibiont?
Crusty_Crab posted a topic in General Fossil Discussion
This is Isorthoceras sociale (Hall, 1877) from the Ordovician Elgin member of the Maquoketa from the well known Graf, Iowa location. They exhibit unusual preservation, including nacre and hollow camerae. According to Invertebrate Fossils (1952) by Moore, et al,, shells of nautiloids have an inner annulus layer, middle nacreous layer and outer porcelaneous layer. Is the circular pitted texture on the outside then the remnant of the porcelaneous layer of the shell or some sort of epibiont like a bryozoan? Plate 220 of Shimer and Shrock's Index Fossils o -
Hi everyone. I am new to the group and would like to ask for some help in identifying this fossil. To my eyes it looks like a cephalopod but never seen one this big. Can some one help? I found it along Etobicoke creek. Any help would be much appreciated .

Good evening to all participants! I have accumulated a lot of local (from Ukraine) material - I decided to sort it out, and recurring fossils, or not of interest to me, offers you an exchange. Everything in the photos is one lot. Consists of: 1. Tile from Carboniferous period with fern print; 2. A fragment of the armor of a armored fish Podolaspis Lerichei of the Devonian period; 3. Tile with Silrian brachiopods and tentaculites; 4. Mollusk of Neogene; 5. A small fragment of a fossilized araucaria of the Carboniferous period with quartzite crystals; 6. 2 fragments of orthocer

I was trying to find the longest straight shelled cephalopod length but was unsuccessful, I heard anywhere from 7-14 feet. What's the real answer? Thanks.

Hi! A recent walk in the woods resulted in the discovery of this nautiloid. I found it in Wilson County, TN which is Ordovician. I am super excited about this because we found it in the woods on the property where I grew up, which means I probably walked past it a million times, and it's 3D so it shows the the siphuncle, and the outside of the phragmocone. We did not have anything to measure it with but I would estimate it to be about 12cm (5in). So my questions are these: I think first verify what I think this is and what I see as I am new to this. I have looked around t

What type of fossilization is if we see a flat white orthoceras on a black stone? Many sellers cut the stone in the shape of orthoceras shell, to believe that is the whole animal sell. Please help, because i can't understand what type of fossilization is this.

Bought this for $5.00 at an estate sale this weekend..........so.......there's absolutely no information on it, but someone prepped this. I believe it contains two species of Orthoceras? - off to the side, is this a different species?, or just a different plane of the same species?.......sorry- don't have specific measurements but the prominent one is about 1" wide and 7" long.......thanks!

I am back from my trip to morocco. It is a 14 days trip and I got 4 days for fossil hunting. It was so imagine, fossils are everywhere and even though I won't be able to dig, I still get plenty to bring home. Since my guide doesn't speak good English, I am not be able to ask him must so I need help to identify the fossil. On the first day, my guide took me to a place near Erfoud to search for dinosaur teeth. It is very close to the highway. We found a well that the local people dig to get Spinosaur teeth and bone. My husband went down to one but couldn't find anything because

Hi! A friend of mine sent me some photos of some objects he have found on Gotland. I guess the first one is coral, the second may be an orthoceras?, The third I have no clue about. What do you think?

After a bust season in Florida for the Peace River, it has been way too high. I am excited to be planning a trip back to Newberry, Mi. Two years ago when I was there, I was able to collect at a degrading hill side east of the town. There is a quarry of Collingwood Shale south of the town, but I was fortunate to find drift cobbles, and some Collingwood Shale on a friends property. Last time I found several nice impressions of Pseudogygites , mostly just the pygidium. I also found a couple of kinds of graptolites, and brought back a 4 inch thick, 16" long slab of shale with a nice orthoceras imp

Fossil that looks like a finger, found in Puerto Rican beach site
GallinaPinta posted a topic in Fossil ID
So the beach was recently excavated and what was covered by the ocean for so many years, dried out and the sand was excavated and made into huge dunes full of old seashells and mysterious oysters and conches. I found many bivalves and i stumbled upon this weird stone that is covered in fossil like formations and shells. Any idea what it could be? Is it a fossil? Is it extinct? Its driving me NUTS. -
this year's first hunt was not entirely successful. There is still a meter of snow in some places. Found some small fossils that I don't think are possible to identify. I may show pictures of them, but saw several large orthoceras and some trilobites in a mountain wall where the snow was melted (exposed to the sun). May have to wait a few weeks, after Easter before i can go fossilhunting. The area where i took these pictures is called fossildalen/fossilvalley in slemmestad. The fossils here in the area stem from the time periods of Cambrian, Ordovician and Silur, a period of 541 million to 419
