I found this tooth (2.75 mm length) while sorting micro-matrix from Post Oak Creek in Texas (Turonian). I had originally hoped this might be a posterior Coniasaurus tooth based on the more conical tooth type and root but have since found in publications that some Pycnodont tooth forms closely overlap posterior Coniasaurus teeth in general morphology. My guess would now be some kind of less common type of Pycnodont tooth form (the flat types are common in the samples) but I wanted to see what others thought.

I recently acquired this nice little tooth from the Carlile Shale of north central Kansas, which I believe is Turonian in age. It looks like Cardabiodon ?venator to me, but I don't have much experience with the genus. What do others think? The tooth measures 27.17 mm along the slant and is 21.66 mm wide.

During the Christmas holiday we had the opportunity to go on 2 field trips to the north of France. 1st one was just after Christmas when we visited the Turonian part of the cliffs. Here we found a couple of nice ammonites ( Mammites nodosoides and a realy nice Fagesia catinus ) and a big flint echinoid. (with @Natalie81 and @Euhoplites) The second trip was last weekend, but we had no luck with the weather this time and we had heavy rainfall for most of the day. Also lots of competition that day. Not a lot of fossils to be found that day: a small flint echinoid, a big Mariella sp. but not the best preservation and an Acanthoceras, but this one is still completely in the matrix, I don’t know how this one will turn out. pic's from the 1st day: The echinoids from the construction site: Fagesia catinus all cleaned up the 2nd field trip: a wel hidden Acanthoceras rhotomagense: Rain, rain, rain,.. I almost forgot, Best wishes for 2022 to all the forum members

Hey y'all, here's an ammonite I found in what I'm fairly sure is a small, unmapped Eagle Ford outcrop. I'm hoping to use it as an index fossil, as the target species that I'm hoping this outcrop will produce occurs in the late cenomanian/early turonian Bouldin Flags member of the Eagle Ford formation. I find that the written descriptions that I've read about the bouldin flags geology are inadequate for my understanding, as it seems colors, shades, and degree of textures are up to the interpretation of the reader. Maybe I'm just overthinking that though. Hopefully this ammo helps. @LSCHNELLE, I know you're familiar with the Bouldin Flags - seem familiar? (Diameter=1 inch)

New Jersey Amber (Raritan Fm., Potomac Group, 93.9-89.8 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
A small 2.5g representation of a 41.1g lot of amber from the old Crossman Clay Pit locality. This amber is mostly unsearched, and a few specimens I have inspected contain some inclusions; preparation will be needed to identify these inclusions, however. Spectroscopic and chemical analyses indicate this amber was produced by distinct, related species within the Cupressaceae family. The material from this lot was collected in the early 1990's by the late Kevin Kropiki; he collected at this locality in association with representatives from the American Museum of Natural History: his significant contributions aided and furthered the study of this amazing material and its inclusions.© Kaegen Lau

This weekend we had some nice weather for this time of the year , so we went to the beaches in the north of France for a stroll with the dog and hopefully some fossils. It is a 2h drive from were we live, so we got there around 10 o’clock. That’s around the time that the tide was starting to lower again, so we had all day access to the beach. We started our walk in Sangatte, just under Calais. And went south following the Turonian chalk cliffs. After a while we spotted our 1st fossil echinoid between the flint pebbles on the beach. Further South, the retreating tide started to uncover some interesting chalk boulders that could contain some ammonites. A few half or severely worn down specimens could be spotted, but after a while we found something really promising. A small part of different colour that could be the start of an ammonite rib was peeking out of one of the boulders. A quick hit with the chisel next to it exposed a larger part of what was indeed a large ammonite. We then took our time to clear out the whole fossil. We got it out in one piece , A 35cm wide Morrowites wingi. After this we didn’t get much further down the beach due to the weight of the ammonite in the backpack, but we kept looking in the same area for other fossils. We each found an additional echinoid on the beach and as a bonus on our way back to the car we found a ptychodus tooth.

Fossil hunting trip to Cap Blanc Nez (Cretaceous of France)
ziggycardon posted a topic in Fossil Hunting Trips
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, Cenomanian & Albian. I spent a lot of time searching in the clay deposits which lay on the beach. Besides fossils we also found some washed up marine life: A large jellyfish (Rhizostoma sp.) A washed up Harbor Porpoise (Phocoena phocoena) A washed up Small-spotted catshark (Scyliorhinus canicula) We also payed a little visit to the beach at Wissant although we didn't went there to search for fossils but to visit an old shipwreck

Dear Fossilforum members, I was wondering if the echinoid on this piece of matrix is indeed a Gauthieria radiata and if so, does that appoint this fossil to the lower, middle or upper Turonian? The shark tooth is a Squalicorax falcatus and the piece was found in the Ardennes departement of France. I know the age of a few locations nearby, but the age of the location where this piece is from is nowhere to be found in literature. I also am not sure if I may say where it was (it took a lot of questioning to find out where it can from haha). Therefore I hope that the echinoid perhaps could be used to appoint a specific age to it. In anycase, thank you very much for your answers, Kind regards, Sander

I have several Heteromorphs but none have such large protrusions. Are these called horns? I worked on this for an hour trying to expose as much as possible, it's buried in bacculites. Found in shale in north Irving TX, inc. pic of other ammonites found there.

Stabilized with Butvar B-76; repaired using an unspecified cyanoacrylate. Identified by Dr. Alexander Averianov as a sacral vertebrae of a juvenile Levnesovia transoxiana. The specimen is either from Dzarakuduk or an excavation near the city of Uchkuduk many years back.

It has been to long since we posted a fieldtrip, but the curent worldwide situation did hamper our fossil hunts. A few days before Chritmas the situation in France changed and we could again go to the beaches in the North for fossil hunts. The 24th we went to the "Grand Blanc Nez" to prospect the turonian boulders en hopfully score a few big ammonites. This time we were als prepared for big finds: we took a handcart with us, because the previous time we had trouble to bring a couple of ammonites back to the car due to their weight ( 2 km on foot with more than 30 kg of ammonites is hell ). The weather conditions of the past few days had cleared up a lot of boulders and it didn't take long for the first ammonites to appear. Natalie found the first specimen, a Lewesiceras peramplum from over 30cm in diameter and a while later a loose Mammites nodosoides. A while later It was my turn and I found an large Mammites nodosoides from around 30cm lying between the rocks. a few extra ammonites were found, but of lesser quality. Halfway our day Natalie found a chalk boulder with a few bone fragments peeking out. not sure of what it could be we took it back home to see what the preparation would give. while heading back Natalie found the last ammonite of that day, this time a Fagesia catinus wich was a nice addition since we diddent had this genus in our collection yet. The ammonites where prepped over the following couple of days, but at first sight the bones didn't seem prommising so they were left asside for a while. So earlier this week we picked it back up and tried to prep it further. tou our surprise one of the fragments turned uot to be a complete marine reptile vert Natalie was overjoyed with this fossil. Just waiting for us on the beach : The prepped specimens: Mammites nodosoides ( 30 cm ) Lewesiceras peramplum ( 34cm ) Fagesia catinus ( 27 cm ) The marine reptile vert ( probably plesiosauria )

having been unable to go out a full day to search for fossils for several months due to health problems, thanks to a recent improvement I went yesterday about 100 km from my home to see a site where rudists were found. The first fossil encountered was a huge colony of cone-shaped bryozoans which had fallen and overturned in a depression. (can be 150kg?). I forgot to take my centimeter scale, so in the photos there is my foot, my hand or my fingers .... Then, I found a rock rich in small Exogyra and rare Rhynchonella. Finally, the rudists were there, in a wall (only for the photo, impossible to extract without damage, hope they will remain visible for the next visitors) and some specimen more fragile or altered in scree. I will post photos of the collected samples later because they are very muddy and require a good bath ...(Sorry, Franz, you have to wait some days ) For me it was a great day in the sun, just before the rain returned today!

Hi everybody! Today i wanna show you one of my dearest ammonites...Choffaticeras segne! Making a search by keywords in TFF, i found only three results for this species...so i decided to enlarge the number! Now i present you my Choffaticeras segne: it comes from Goulmima in Morocco, belongs to Turonian (Upper/Late Cretaceous), it is 19cm in height and 1.461kg in weight. This specimen has been polished in both sides, obviously. It's very decorative and it makes its good looking part in my living room. I love its external sutures, how do you call this kind of suture in english? Please, let me know! For who loves taxonomy and scientific classification (like me), i leave you a little pattern that i made. Thanks for "watching" Choffaticeras segne Dominio: Eukaryota Regno: Animalia Phylum: Mollusca Classe: Cephalopoda Sottoclasse: Ammonoidea Ordine: Ammonitida Sottordine: Ammonitina Superfamiglia: Acanthoceratoidea Famiglia: Pseudotissotiidae Sottofamiglia: Pseudotissotiinae Genere: Choffaticeras Sottogenere: Choffaticeras (Choffaticeras) Specie: Choffaticeras (Choffaticeras) segne

ammonite hunting in the Turonian and Cenomanian
Manticocerasman posted a topic in Fossil Hunting Trips
Good tides and a promising weather forecast and we were ready to go for a trip to the French coast ( Cap-Blanc-Nez) High tide was set for 8AM, so we left around that same time, getting there when the tide was starting to go down giving us a whole day of opportunities to search. First stop was the beach of the “Grand Blanc Nez” with the Turonian cliffs. Since our last visit there, there have been high tides and multiple parts of the beach were cleared of the sand. The prospection of the loose boulders revealed for me a large Mamites nodosoides and a Morrowites wingi. I was especially happy whit that last one since it is the first specimen of this species that I found. Natalie found a small belemnite , although this might not seem spectacular, it is probably the best find of the day as they are incredibly rare in the Turonian at this location. On our way back to the car Natalie found another ammonite, this time a Lewiseceras peramplum. The way back to the car then became quite hard due to the weight and sizes of those fossils. In the afternoon we went a couple of kilometers further to prospect the Cenomanian boulders on the beaches near “Petit-Blanc-Nez”. On the first few meters on the beach I found a boulder with a really nice Cunningtoniceras inerme sticking out. Further down the beach we found a few smaller ammonites, but we ended distributing those to a few starting fossil collectors that were prospecting the area. The last good find of the day was made by Natalie who found a small but exquisite nautilus fossil ( Eutrephoceras sp. ) in the Turonian boulders: to late for this one: Mamites nodosoides: Morrowites wingi : Lewesiceras peramplum: in the Cenomanian boulders: Cunningtoniceras inerme: the little nautilus: Eutrephoceras sp. : of cource the pictures of the prepped specimens will follow.

Hello everyone, I saw this specimen for sale as a new species from the Vallecillo quarries. I haven’t seen something like this from this formation. Does anyone have any idea of what species might this be? The size of fossil is approximately 40 cms long. The size of the matrix is 63 cms * 43 cms. The pictures were not taken by me. Thanks everyone.

Today I had a good time with fossil hunting at the Dakota formation (early Cenomanian) sites and Greenhorn formation (Cenomanian-early Turonian) sites in Ellsworth county, Kansas. Typical view of the local countryside, but still beautiful! I keep finding these weird vertebrae-like rocks, clustered in this particular site and not other sites. I suspect it's not vertebrae but I still can't figure this out yet. These mysterious vertebrae-like rocks...reminds me of shark centrum and crinoid stems but I don't think it's them. This site is Dakota formation. I took these home just in case it is identified as fossils later. I think it's fossil vegetation of some sort. Maybe reed or horsetail? I found these jumbled at different locations but put it together and it fitted like a puzzle. I took it home and will be prepped. This is from Dakota formation. Inoceramus from Greenhorn formation. One of the best specimen of this genus I have found so far! Took this one home. Another Inoceramus, pretty good specimen! I also took this one home. Tiny fossil in the center. Greenhorn formation again. This tiny fossil, image enlarged and the ridges/grooves are visible. No idea what it was. I took this one home and will be put under the microscope for identification efforts. The storm was brewing at the distance as the cold front is heading south. It was lightning and I was at near the top of hill, the road would be impassable if wet, so it was time for me to go home! I will be posting some of those fossils on the Fossils ID section soon after it is cleaned up. Cheers!

Hello! I'm a pretty novice fossil hunter, so I look for things that stand out! Recently I found these in a span of about two weeks, I haven't seen anything like them before. The small ones all have a flat/facet on the posterior side, same teardrop shape, and the larger ones look like " big ears" to me, lol. I thought maybe iron concecretions at first, but the small ones look different, in that they are not "round". Ammonites? Reminds me of some of the pics posted of plesiosaur fossils, I have more pics, but the files are too big to post all at one time - I would really appreciate any insight! Fossil pic 3.pdf
