An interesting article on the morphometrics of C. megalodon teeth from Italy Fossil teeth of Carcharocles megalodon: The Collection of the University Museum of Chieti (Italy). Part I: Morphometric Analysis https://www.academia.edu/37963297/Fossil_teeth_of_Carcharocles_megalodon_The_Collection_of_the_University_Museum_of_Chieti_Italy_Part_I_Morphometric_Analysis?email_work_card=title -
Hi guys I’m from NSW Australia and have been finding teeth for the last couple years and just wondering if someone can help identify a tooth and two vertebrae. Thanks!

I recently acquired some matrix via trade from @will stevenson. This matrix is from Hallencourt France. Just the second time we gotten to go through the entire process of breaking down matrix to a searchable form. I am still in the process of breaking it down and only have searched probably less than 20%. I wanted to begin the post now as I had a few minutes to write. The material is Early Campanian in age and from the North of France. Unlike my first experience breaking matrix down which was from a location with no publication, there is a publication. Sharks from the Late Cretaceous of France and England by Guinot, Underwood, Capetta, and Ward. There is an additional publication on the Batoids. The publication covers the Anglo-Paris Basin. Hallencourt has a pretty diverse fauna according to the paper and gives us an opportunity to explore Cretaceous micros from Europe for the first time. Most of what we got were pretty small pieces with 4 I’d call medium sized. It is very hard chalk and is pretty challenging to actually break down. It has given me the opportunity to experiment with different methods for breaking down matrix. I’ve used hot water treatments, vinegar and for the largest piece, freeze and thaw for the first time. It has been an exercise in patience lol It is also proving to be an invaluable experience going forward. We haven’t searched enough to really have a full sense of this particular matrix but the early results are mostly Chiloscyllium and Anomotodon. So far, 22 Chiloscyllium teeth and 11 Anomotodon though almost all are partial. Very few complete teeth except the Bamboo teeth. Most surprising find so far is easily a Synechodus. Only one tooth was found during the study according to the paper. We have also found Squalicorax (1), Carcharias (2), Scyliorhinus (1), Squatiscyllium (3) and our first ever Eoptolamna tooth ! There is A LOT of dermal denticles in this matrix and at least 5 distinct types. We also found one small Shark vert. Its a grind. Quite a bit of work. Way less dense in shark teeth than our Mesaverde stuff was and not real diverse so far but there is a lot of searching left to do. The lack of density does make any find pretty cool though. I will update this with better pictures after everything is completed and I have the final results. I’d like to thank Will for the trade that brought the matrix. Very cool TFF Member!!!! 1st pic the bag of matrix before breaking down 2nd pic Anomotodon hermani 3rd pic a slide with a few of the finds

How Scarce are Fossilized Great White Shark Teeth
Jurassic_Joe posted a topic in Questions & Answers
Hello everyone! So something that I have been wondering recently is what is the prevalence of fossilized great white shark teeth? Any time I go online, into shops or shows there seems to be a lack of fossilized great white shark teeth. I always see megalodon teeth, mako teeth, and other fossilized teeth from all kinds of species of sharks but rarely do I see fossilized great white shark teeth. Is this because they aren't as common? Or are they just not as high of a demand as other teeth such as megs or makos? From what I understand they can be found in the Carolinas, Chile, and even here sometimes in south Florida in creeks and sometimes in Bone Valley. I own a few of my own but they weren't easy to find. Please let me know your thoughts. If you own some yourself please feel free to share! I would love to see them! -
Sometime last week I went to a creek in Southeast Alabama to find shark teeth. I got thirty nine teeth and what I believe is a partial glyptodon scute. I believe that the majority are sandtiger teeth (but from YouTube and online images could be goblin) and a few mackerel shark teeth. I also got my first tiger shark tooth from this site. I was hoping someone here could help identify the scute and supposed sandtiger teeth.

Before going back to the ESCONI Gem and Fossil Show, I decided to leave the house early and make the 75 minute trip to Oglesby, Illinois to a roadcut that I like to collect and was last there 19 days ago. This roadcut, exposes the Pennsylvanian LaSalle Member of the Bond Formation. Within those 19 days, portions of the head wall came down, dropping several thousands of pounds of rock. As I have stated in previous posts, this is not a road cut for younger collectors and people who are not sure-footed. Here are a few pics of the exposure as I found it this morning. This tree branch….. broke off of this tree after being hit but a lot of rock. The rock that I am holding broke off of the larger piece in the background during the fall. The large boulder in the left of the picture that has my Estwing stick on top fell all of the way down to the base of the cut. I am guessing that it is a distance of about 50+ feet. Here are a couple pictures of some of my finds. Three different species of brachiopods in this freshly freed piece. Here is my first Conularida and it is next to an inarticulate brachiopod. I will post a better pic at the end of the post.

Trip to Florida last week was quick and exhausting. Wimped out on the planned Peace river trip, as was in 30s unexpectedly and I had not brought appropriate clothes. Instead did nearby Bone ValleybFossil Farm and enjoyed the day sitting in a lawn chair with a hose, washing out material (laziest AND muddiest fossilhunting ever). Couple next to me found 2 megs, I found three partial megs, dolphin tooth, partial whale tooth (?), fish plate, and about 20 other partial and complete shark teeth (bull, lemon, hemi). Found small piece (2?) of mastodon/mammoth/gomphothere tooth, pretty color and thick, but not enough material to distinguish. And a partial bison(?) In addition found several larger coral pieces in mixed rock/gravel/debris along road near Ft Myers. (weather damaged, construction damage, but good for my collection)! One small mystery piece there, too.

Wanted to share one of my first trips to a new location I went to last year. I was only checking the area for fossil evidence and was blown away at what I found. I was there for 2.5 hrs and could not believe what I left with. Completely surprised and could not be happier. This place has stayed on my mind ever since. lol. <·,^ ><

Microscope recommendation for taking photos of shark teeth
hemipristis posted a topic in Collecting Gear
hafa adi folks, I am looking for suggestions/recommendations on UDB microscopes for the predominant purpose of taking pictures of shark teeth, generally small fish material, coins and thumbnail mineral specimens. I did a search through the topics on FN figuring that mine can't be a new question. While I found a couple of threads but they were a bit dated, and I wondered if there are new equipment on the market. While I'm not overly budget conscious, I'm hoping for something around for a couple of hundred bucks (USD) or less. Now for the dumb question: I assume that I will need a different scope, something more akin to a dissecting scope, for hand specimens? I appreciate any response, and thank you. signed,.jpeg.2c207575181dff559da774efc370b5d0.jpeg)

From the album: Sharks
I ran out of room in the other display, so I split the collection into extinct/extant species. I probably still need another riker! For scale, the big great white tooth is about 2 1/4" slant height. In red are species that are endangered or critically endangered. The only teeth I regret having are the modern Makos, I had gotten them for comparative reasons (both are anterior, left is upper, right is lower). The fossil Mako is actually an I. desori (a big one!), but I included it since it's so morphologically similar to the extant species, and a few people would say they're synonymous. Species included (obviously will grow): Alopias superscilliousus Alopias cf. vulpinus Sphyrna zygaena Sphyrna mokarran Carcharhinus obscurus Carcharhinus plumbeus Carcharhinus brachyurus Carcharhinus falciformis Carcharhinus leucas Carcharodon carcharias Carcharias taurus Galeocerdo cuvier Isurus oxyrhinchus Lamna nasus Negaprion brevirostris Rhincodon cf. typus -
3-1-22 Oglesby, Illinois Pennsylvanian Roadcut Collecting
Nimravis posted a topic in Fossil Hunting Trips
On Sunday I took trip to a roadcut that I like to collect. This roadcut, about 75 minutes from my house exposes the Pennsylvanian LaSalle Member of the Bond Formation. I have been to this site numerous times, as have @deutscheben and @connorp. If you search using the word “Oglesby”, you will find numerous posts with some great stuff that comes out of this roadcut. Well back to the post. On Sunday the site still had too much snow cover to try and collect at this location, so I left. So today I had a choice, go to the Mazon Creek area since it was the official opening day for the collecting season or head out to Oglesby. I choose Oglesby and I was the only person there. I spent a few hour searching, cracking and collecting at the site. Found the usual suspects in brachiopods, collected some, left most for others. Found a slab of rock that had fallen off of the head wall a few years ago, but this thing I decided to break it up. I found numerous, what I believe are shark teeth, some I know for sure, others not too positive. Unfortunately, nothing was complete. If I would have broke it up a couple years ago, the biggest one might have been intact and complete, but who knows. Here are a couple pics the the site. Here are some pictures of fossils, as stated previously, I did not collect all of these.

Hello, I am a retired paleontologist who has been away from the field for 25 years and still look for fossils on occasion.

Found these on Shark Tooth Island near Tybee Island Georgia. Can anyone help me identify them? Let me know if more pics are needed

My best guess is the black shark tooth is a sand shark and maybe the grey is a great white . . . have no idea what the gold sample is! Any thoughts?

I have taken almost six months off from my favorite fossil adventure - shark tooth hunting. I was a little hunted out after a torrid pace in 6 years that saw me and my wife finding over 1000 Ptychodus teeth and some rare pliosaur and mosasaur teeth during maybe 50 to 100 small outings each year. We even traveled to Wyoming and the Dakotas "to check off some unvisited United States". But, much to her chagrin, I/we got a lot of fossil hunting time in at the expense of other trip priorities. Yes - I was obsessed with Ptychodus. But, I think that I am now a little more even-keeled. During the six-month hiatus, I took the time to pass on some of my local knowledge to help @Jared C. in his Central Texas area fossil adventures. He and his brother found and excavated a partial basal mosasaur skull from somewhere locally. I asked him not to tell me where (I have no idea) because I enjoyed helping him and I didn't want to spoil his enjoyment of the chase. Note to experienced fossil hunters - new eyes often see things in an unconventional way. And, that is a good thing! I try to look for and learn new things every time I hunt the same area. So, in middle February 2022, there we were together for a couple of hours in the creek in one of my favorite outcrops. It wasn't the sunny day, I had hoped for, but most importantly it fit my wife's schedule. She gave me a Christmas gift of monthly fossil hunts with her! Such a gift, even after dragging her through the baby mosquito hatch in South Dakota to find a rainbow colored ammonite! Now, that's love! Not the ammonite! You can find 8 or 9 species of Ptychodus in 30 vertical feet of Eagle Ford and Austin Chalk - Atco outcrop - all at predictable stratigraphic levels along a 400 yard long stretch of creek. I learned that Ptychodus strata marker fossil trick from Shawn Hamm. Here are pictures of a few teeth from this hunting spot from one of my favorite Ptychodus species (occidentalis). One, I found in the February 2022 hunt and another in 2021. The third tooth in early 2019. The first one has a little snail-like curl at the middle of the crown. The second is a rare upper medial file - so, strange in shape and form. They are both 10 mm or less in size, but nearly flawless and unique. Still hoping for another 25 mm+ size P. occidentalis from there but without the smashed off crown top (third one in last two pics). Happy hunting! But, I encourage you to stay even keeled. Don't get too crazy! It's just a pretty rock! But, it still can be amazing!

Here are 8 teeth from Douglas Point, MD. Aquia Formation. Thought I’d get opinions. The first 6 are around 5.25 mm. The last 2 are 2 mm. I have 75 more to go through and decide on ID.

I’m heading to The Netherlands at the end of March. Does anyone have current information on the best sites to collect shark teeth or other fossils? Thanks!
