Hello, first post here, found what I think might be a belemnite? Unsure though. Found in dirt near drainage ditch just outside loop 1604 South side of I35, map says pecan Gap chalk but I'm no good at IDing formations, any help is appreciated. PS I have other fossils I'm unsure of from another area, new thread or here? Thanks, Raymond.

Hi, I posted a fossil ID question last week, and today I went back to the very same location and searched for a few hours. I think I found some more fossils, but they look very different from what I am used to find, so I'm not sure even all of them are fossils? Thank you for your time! All the best/ Linus ----- For reference this is the previous fossil ID question with the very detailed sponge -> 1. I'm pretty confident this is a fossil. I also found a belemnite at the same location that I added for reference. It looks round, I don't think it is broken more than the "top". 2. For the record, I didn't crack the stone, It was already cracked. Inside there is something that looks very much like a sponge or very large seed. But I'm puzzled by how the stone looks overall? 3. I'm not sure this is a fossil. But perhaps it is the base of a coral? 4. I'm not sure this is a fossil either... but there were a few samples that had this peculiar look. 5. There were also a few samples of these "sausage fingers", I placed them along with the belemnite for reference..

@TqB Typical fractured belemnite Cylindroteuthis pusozianna guard but with curvature towards the tip, could this be a preservational feature or maby some sort of pathology. From the Lower Oxford Clay, Peterborough formation, Callovian stage.

Hey, I’ve finally spent some time on the Jurassic Coast the last few days around Portland, Lulworth Cove and Lyme Regis / Charmouth beach and thought I would share what I’ve found. Not loads but my own first fossil which I’m pretty proud of even if it’s tiny lol! It’s part of a infant ichthyosaur neck vertebrae if I’m correct. Also some photos of Ammonite imprints on some big rocks and a rock I found and broke open with an ammonite imprint and possible tooth imbedded in it? Also random photos of not sure what lol let me know please what you think.

Is this a belemnite phragmocone? I found this today in yorkshire.

Hey! Picked up this really interesting belemnite 1 month ago when I was in Lyme Regis, England. It is very weirdly curved, I was wondering if it could be pathological. (Don’t even know if it’s possible). Maybe just a rare fossilization??? What do you think? Ps: it broke naturally so I had to repair it with glue (black line)

From the album: Vaches Noires spring 2018 and a bit of 2016
a pyritized belemnite phragmocone from the callovian of "les Vaches Noires" Cliffs - collected during april 2018 -
Hi all, Can anyone help me identify these belemnites from Speeton? They were found in the rare Kimmeridge Clay beach exposures, all in situ. The first is a stunner at 19cm long and has no distinguishing features. The second is about 12.5cm long and has a deep groove running from the tip to about halfway - is this cylindroteuthis? The third is smaller, at 8cm long, and you can just make out a similar groove (but shallower) down half of its length from the tip. Many thanks! Gillian

At over 4" across, this is the last few chambers of by far the largest diameter belemnite phragmocone I've ever seen. (If anyone has one from a Megateuthis, I'd love to see it! - they don't seem ever to be preserved.) Given to me by a friend, it is in a nodule from the Jet Rock (Upper Lias, Lower Jurassic) of Port Mulgrave, north Yorkshire coast. It must have belonged to an exceptionally large Acrocoelites trisulculosus which is probably the only belemnite to occur in this bed. It's a large species anyway - typical rostra of it are 5 - 7" long but about 9" has very rarely been recorded so a bit longer may be possible. Photo 6: Not having such a large Acrocoelites in my collection, I've done a conservative mock-up of it with a smallish (9") Megateuthis and another piece of phragmocone which is my second largest... A total length of 20 - 24" seems about right. Photo 7: For comparison , I have a complete but crushed example of A. trisulculosus about 12" long, the rostrum being 6.5". 1) 2) 3) 4) 5) 6) This should probably be stretched more... 7) A normal size Acrocoelites trisulculosus with crushed phragmocone (the strange ridged structure on top of it is a crushed on-edge Harpoceras shell mouth)

Chitinobelus, a strange and rare belemnite? from the Posidonienschiefer
TqB posted a topic in Member Collections
Extremely rare, I never thought I'd get the chance to acquire one of these so I was very pleased when one came up for sale. Chitinobelus acifer Fischer 1981, a belemnite (or possibly belemnotheutid) whose rostrum was originally composed of aragonite with organic material. As a result, it's preserved as a compressed organic film with the aragonite lost to diagenesis. Belemnites are nearly always mostly calcite (largely thought to be primary) and preserve 3D in all sorts of rock. There is argument (quite complex) over whether this is an unusual aragonitic belemnite or something a bit different. There are prominent striations which are similar to those in the "normal" belemnite, Salpingoteuthis. From the Jurassic, Lower Toarcian Posidonienschiefer of Zell (not far from Holzmaden, Germany). As far as I know, this is the only locality it's been found. Phragmocone chambers just visible.

This is a very recent find from the Cahaba River Valley. One person on the Facebook page identified this as a belemnite. Is this the general consensus? To my knowledge I have never seen one. I have a regular paper clip for size reference.

Greetings again TTF! The Billings formation is just filled with stuff that I can't identify! This time, I have found some glossy, cylinder-shaped things in the Billings Shale. I know that conodont elements are known from some parts Ontario and Quebec, but I think that it might be a belemnite as well. They seen to be associated with crinoid stems, brachiopods, and one Pseudogygites Lantimarginatus pygidium. They are each roughly one centimetre long. They are in the centre of the first picture and the second picture.

Belemnite Madagascar?
Seguidora-de-Isis posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello! Good afternoon to all! I have noticed that every year, the Chinese import tons of these supposed belemnites from Madagascar to resell over the internet. And now, I noticed that a Chinese seller announced on our favorite auction site that these belemnites are of the species belemnopsis tangarensis. My question is whether these belemnites of Madagascar are real even, and is there any scientific study that could actually define them as being of the belemnopsis tangarensis species? And what is the age in millions of years of these supposed belemnites? Thank you for all kind of help!

Whatdup guys! I've got this piece from one friend of mine and idk what it is.Your help would be nice as always! I was thinking that this is maybe a belemnite part cause my friend is telling me that he gave me a fossil but i'm not quite sure! Thanks anyway!

A very nice Belemnite, uncommon at this site. At 83.7 mm or 3.29 inches, a fairly good sized one.

Belemnite Fossils SITE LOCATION: Lias Altdorf, Germany TIME PERIOD: Jurassic Period (~ 180 million years ago) Data: Belemnitida (or belemnites) is an extinct order of cephalopods which existed during the Mesozoic era, from the Hettangian age of the Lower Jurassic to the Maastrichtian age of the Upper Cretaceous. The belemnite is the state fossil of Delaware. Belemnites were superficially squid-like. They possessed ten arms of equal length studded with small inward-curving hooks used for grasping prey. However, they lacked the pair of specialized tentacles present in modern squid. Belemnites (and other belemnoids) were distinct from modern squid by possessing hard internal skeletons. The internal skeleton was composed of the guard or rostrum (plural: rostra), a heavy solid structure at the posterior of the animals. The rostrum was usually bullet-shaped and projects prominently backward, but in the suborder Belemnotheutina, it was only present as a thin layer. While the inherited camerate portion of the internal skeleton (see below) was of aragonite, the evolutionarily novel rostrum was composed of calcite. Due to its more geologically stable calcite constitution, the rostrum is often the only remains of the animals preserved, often in very large numbers in a given area. The rostrum is in turn attached to a chambered conical shell known as the phragmocone. At the tip of the phragmocone beneath the rostrum is a tiny spherical or cuplike nodule known as the protoconch, the remains of the embryonic shell. The space between the phragmocone and the rostrum is known as the alveolus (plural: alveoli). At the forward part of the phragmocone is a thin very fragile structure known as the proostracum (plural: proostraca). It is usually spoon-like in shape. It extends over the dorsal part of the mantle. Fossils which preserve the soft parts of belemnites indicate that like modern coleoids, they possessed an ink sac, hard beaks, tail fins that were either apical or lateral, and large eyes. Additionally they had a pro-ostracum which is a tongue-like projection from the main body of the shell. Well preserved specimens have even retained evidence of strong muscular fibers in the mantle, indicating that they were powerful swimmers like modern squid and unlike other cephalopods of their time such as ammonoids and cymatoceratid nautiloids. Kingdom: Animalia Phylum: Mollusca Class: Cephalopoda Order: †Belemnitida -
I went on a forage with @Barerootbonsai in the summer. We walked from Charmouth to Stonebarrow and found some great belemnites between Golden Cap and Stonebarrow Hill. They are from the Belemnite marls, Lower Jurassic ,Pliensbachian. I’m thinking there are two species here. Top two are the same and bottom one different. @TqB

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.

Please help identify this fossil found in Big Brook NJ. Similar to Belemnite but much larger than what is normally found in Big Brook, and has the pocked outer surface (see Belemnite samples in 3rd picture for comparison)..

The phragmocone is partly in a nodule, the rostrum protruding from it - quite rare in these beds. It has the remains of an epirostrum. Assigned to Megateuthis in: Doyle, P. 1990-92 The British Toacian (Lower Jurassic) Belemnites. Monograph of the Palaeontographical Society, London: Part 2, 50-79, pls.18-28 (Publ. No. 587, vol. 145 Contentious taxonomy down the years - diagnostic features include the pair of dorsolateral apical grooves. Similar specimens of Acrocoelites sp. are supposed to have an additional ventral groove but this is variable ...

German Jurassic Belemnite bought online. -
Hi Again ...I'm posting another nice for New Jersey Fossil .....its a Belemnitella Americana they are very common fossil for New Jersey but its very hard to find them with anywhere close to being complete...The rostrum that is. I put the two Exogyra's on the block for the fun of it but the Belemnite was found insitu laying long wise just exposing itself. I left the Belemnite in the block that I dug it out of and the Rostrum measures 4 3/4 inches.

After splitting some clay shales this morning I wondered how these two fossils would have come together. Thank you for looking

Following on from a post in the questions forum, I was trying to identify this species of belemnite that I picked up on Friday from the Oxford Clay at Whittlesey, and learn generally how to identify species myself, rather than squeak 'thunderbolt' excitedly. It struck me as unusual partly because its shape is different from most of the belemnites I see in the Oxford Clay, but also because of the strange white coating. Aragonite is preserved at the site, and I thought perhaps it had aragonite around the calcium carbonate rostrum. Sadly it broke as I extracted it from the clay. It is conical, depressed, very acute and has a deep groove. I was using Fossils of the Oxford Clay to identify it, but although it is most similar to Belemnopsis bessina, I then decided it couldn't be because it is not hastate. But rereading the description it does say it can be weakly hastate, and it might be. Also in favour of this specimen being this species is the flattened apex and kidney shaped transverse section caused by the deep groove. I was possibly overthinking things. It would be reassuring to have other people's input Other features include a strange ridge on the reverse. Not seen that before. Also, just for fun, an 8mm belemnite. I'm not expecting to ever identify it, but it's cute and I thought I'd share.
