Hello everyone , I have been trying to identify this fossil for a while now, nobody seems to know. This is a fin spine from the upper cretaceous (campanian) of israel. Recovered from phosphorite rich marine deposits. It reminds me of hybodontiformes, but its different as it lacks their characteristic serrations, and by that time period they should have gone extinct in the ocean. Any help would be incredible!!

I know this little guy is worn, but can it be IDed? Could it be a meg? Slant height of 8 mm and width of 8 mm. Found in the Summerville area. Thank you!

I've had this tooth for at least a few months, but just came across it again and am wondering what it is. I see features of a few different sharks, but not enough of any particular one to be confident in an ID. 9 mm slant height by 8 mm across. It would have come from my usual areas near Summerville or the beach. Thank you!

So is this a pathological (or very posterior) Hemipristis serra lower, or is it a Physagoleous contortus? @Al Dente @hemipristis

It was a very nice day out on the bay. The site I was at exposed both the choptank, and the st. Mary’s formation. I was really hoping to find a large megalodon since there had been a massive storm the other day but that didn’t happen. Oh well, I still stumbled onto some great finds. This beach was pretty much in the middle of nowhere, so there wasn’t a soul to be found here. I was the only one there. It was quite peaceful. Here are the finds: The complete grab: The complete grab flipped: All the better finds: These fossils include a mako, three snagged toothed sharks, a pathological carcharinus, two awesome crab claws, a ray plate, and my longest bird bone to date. All and all not a bad day! The best find flipped: The pathological tooth: Flipped: There weren’t any teeth the size of my hand found like I was expecting but this was just a fun day as always. Now what I’m really excited for is this weekend coming up. I think you guys are going to be pleasantly surprised with this weekends finds.

Any thoughts on the type of teeth found here? Found recently in a Monmouth county creek. One appears to be a crow shark, possibly a shark vertebrate and unsure of the others.

Any thoughts on what type of tooth?

Here's a tooth I bought with several other specimens from the same locality (Upper Burlington Limestone, Biggsville, Henderson County, Illinois) back in the 90's. It has smooth enamel and is 1 1/2 inches (37mm) along its longest dimension. I have another tooth much like it but it is much smaller and I've seen other teeth like it but this one is the largest I've seen. Years ago, one collector thought it could be Chomatodus but that doesn't match what I see elsewhere. I think it is a tooth form that has been tentatively identified as Orodus or a relative in the past but I don't know Carboniferous teeth like I know Cretaceous-Cenozoic teeth. This may be a lateral tooth of a taxon with different anterior teeth.

Hello I've been "fossil dormant" for quite a while, but was on the beach yesterday and found these (the recent storms have churned/coughed up some new layers I think) the start tooth may be hard to ID without any of the bourlette, but I can tell you that it has absolutely no serrations - perfectly smooth cutting edges. Mako? As for the small conical tooth, I think it is alligator, but I'm not sure if alligator teeth have distinct sharp crease from tip to base on opposite sides like this tooth does. Thanks for any advice

Hello, I am making a great of in-situ pictures of my fossil hunting trips for this year. We now have a foot of snow in the ground so fossil hunting season is over. ☹️ These pictures occur in Wyoming, Montana, South Dakota and North Dakota. Mostly Cretaceous aged sites but some Eocene from ND. They are mostly tooth related. I hope everyone likes in-situ pics as much as I do!

I friend of mine has sent me this,I searched on internet but we can't find what it is.can anyone tell me what is this.it look like old teeth but I'm not sure.tnx for help

Could you please tell me which shark this tooth belongs to? It is from Ukraine

Hello everyone, I'm going to start my shark teeth collection and actually I don't know how to identify a fossil shark tooth and differentiate from a modern shark tooth. I hope you can help me because I am really enjoying this topic and I want to learn more about it.

Dug into this park on Tuesday for a few hours. I really have no experience with Mesozoic strata, aside from Coon Creek of Tennesse. The water was inconsistent in it's depth due to a local beaver dam causing higher than normal water levels. Material here consists of unconsolidated clays, gravel and sand. Here are two large bivalves I recovered from the upper beds containing clams. I believe these are Exogyra costata which are common at this location. This tooth belongs to Scapanorhynchus texanus in which the teeth are referred to as belonging to goblin sharks. This is untrue, as this taxa is distantly related to modern goblins but I believe they are within the same family? This is a pair of small bivalves, species possibly being miniscule Gryphaeostrea vomer? A single Agerostrea mesenterica. Finally pictured below, an unknown, based on corrected advice it is a worn Pycnodonte. This trip was long, but the report ended up being brief due to the difficulty I had getting into the productive zones at this site. In which happened to be straight down, through the toughest clay I have ever seen. I did however end up meeting one of the park volunteers named Doug, who was more than helpful, he frequents the area and is very friendly.

Thank you for opening this topic. This is my first post here and I am very interested in what I found. I would be more than happy to include more details or pictures needed. Just let me know. Info below: This was found at the beach near Panama City, Florida. It was found just rolling around in the breaking waves. The sinus cavities caught my attention It is approximately 1.5 inches or 3.8 centimeters long

A small Johnlongia Sharks tooth from Cretaceous material NW Queensland this is the first one we have found this year.

Hello everyone, I found these shark and ray teeth on the seashore between Knokke and Het Zwin, in Belgium. Could someone help me to identify them? Thank you in advance.

A couple of weeks ago, @Jackito, his son, and I took a trip out to one of his favorite Eagle Ford sites. For those of you who are familiar with Carter's posts, this was once the famed location of the so-called "giving rock", so the bar was set high for the day. I've come across some of Austin's eagle ford material in the past, but it was always only the leftovers of what had been washed through miles of rushing creek water. This was my first time getting to poke through the source material, so I was eager to see what could be found. The water was low and the temperature mild. I was thankful I wouldn't have to suffer trudging around in soggy shoes. As we walked beside the creek, Carter explained the various layers and where the best stuff could be found. He pointed out the notable spots where things like pseudomegachasma and pliosaur teeth had been dug up. I knew to not get my hopes THAT high up, but it was certainly a good motivator to stay attentive and expect the unexpectable. It took me a while to get the hang of pinpointing which slabs were best to open and how. Carter was nice enough to share some of his finds, and I must admit, not everything pictured below was necessarily first spotted by me . I was quickly surprised by the sheer number of shark teeth we started finding. Being the completionist that I am, I would immediately try to excavate every tooth I found. Carter advised me that simply bringing the matrix home and processing it there would be the most efficient use of time which I have come to agree with. Every tooth had fantastic preservation and would often pop right out of the shale (though not necessarily in one piece). The Ptychodus teeth were the most mesmerizing. They basically broke off without a speck of matrix still attached and had a beautiful shine. Thankfully, they were also robust and rarely fell apart. A decently sized Ptychodus still in matrix The amount of Cretoxyrhina to be found was also staggering. Unfortunately, they required a little bit more delicate prep than what I had to offer in the field, so my ratio of broken to unbroken teeth was higher than I'd like to admit. In my defense, I managed to lower that ratio as the day progressed. Squalicorax was also a common sight along with various fish teeth. Carter's son managed to find some turtle material... that was still alive and may or may not have come from out of the stream . For most of the hunt, Carter and I had some nice discussions on things to be found here in Austin along with various chats about life. The hours seemed to fly by so fast, it wasn't long until Carter and Jack had to head on out. They'd been wanting to find some mosasaur material for a while, so I sent info on one of my favorite sites (the place where I came out with 4 mosasaur verts in a day). Hopefully we'll get to hunt together over there some time in the near future. I stuck around as I had a couple hours to kill before needing to drive to a friend's birthday. The rest of the time was spent doing more of the same. I managed to come across a huge Cretodus tooth, but the root was unfortunately nowhere to be found. I also started gathering some of the leftover matrix for later processing for microfossils. The layer was just so rich, how could there not be something cool to find? I filled up a couple Ziploc bags with the stuff and made my way out, thinking of ways I could clean this while residing in a college dorm. The richness of fossils in the matrix. This piece was a little too stony to break down though. Might try vinegar. Suffice it to say, I figured out a way to clean it without clogging the communal sinks, but it's a slow process. Though, I must admit, it's nice to come home each day to a cup's worth of dried micro matrix ready for screening. In only my first batch, I found something I think is pretty amazing. What was at first just a shiny little speck, upon closer analyzing, may, in fact, be a tiny coniasaur tooth! It has that characteristic bulging crown that is instantly recognizable. Hopefully I'm not jumping the gun on this one. A couple rounds later, and many many puny Ptychodus teeth, I managed to spot what appeared to be the tooth plate to a Pycnodont fish or something similar. After some delicate cleaning and lots of paraloid, it's still a little bit scuffed, but there are definitely some little round bulbous teeth in close association. The tooth plate before and after cleaning. Can anyone confirm if it's Pycnodont? There was plenty bony fish and shark material. Interspersed within them were some that eluded my identification (including mayyybe Paraisurus?). I've got plenty of matrix to still go through, so I will post updates if anything cool is found. For now, here are some pictures summarizing the finds: Please excuse the hand pics. It's just that the details come out better on a slightly darker surface as opposed to white paper. Closeups of Coniasaur(?) Tooth L to R: Bony bits, "Coniasaur" tooth, and "Pycnodont" tooth plate The best of the Ptychodus and a close up of the smallest one. The bottom left is smoothed over. Is this maybe feeding damage? Also, any ID for species is much appreciated : Cretoxyrhina mantelli. My favorite is the fat one on the left Best of the Squalicorax falcatus. Right two are a little strange. Possibly symphyseal? Best of Scapanorhynchus and huge rootless Cretodus (hard to see in pic, but its got the wrinkling): Paraisurus? I saw that genus mentioned in a Shawn Hamm publication on the Atco and thought it could be a match. The roots are very skinny on both specimens and the teeth seem vertically stretched. The larger tooth on the left initially appears to be missing half the root, but it is actually nearly complete. The only break is a tiny portion of the root at the very top. The right specimen is very fragmented. No signs of cusps nor nutrient groove on either one. Cantioscyllium orals and Sawfish Rostral Teeth: L to R: Enchodus, Protosphyraena, and Pachyrhizodus Some oddballs. The left is a fragment of some sort of multi-cusped shark tooth. The middle is a a segment of some barbed material that seems similar in appearance to the fishy bits found in the matrix. The right specimen is a shiny crescent shaped thing that I have found in other micro matrixes from Moss Creek and POC. Never kept them, but now I'm curious after finding them again: Thanks for reading!

Yesterday I went on a combined field trip with ESCONI and LOESS to the Starved Rock Clay Products pit in Utica, Illinois. ( @connorp was there too!) This open pit exposes the Pennsylvanian Mecca Quarry black shale, Francis Creek shale, Colchester Coal, and an underclay below the coal- an assembly of strata that have produced world-renowned fossils elsewhere, including Mazon Creek fossils further east and complete sharks from the Mecca Quarry Shale in Indiana. At this location, unfortunately, the concretions are almost all blanks but the black shale does produce isolated fauna including bivalves, brachiopods, cephalopods, and shark teeth and scales. The underclay also contains petrified and pyritized wood and root traces. About 30 of us gathered at a nearby McDonalds before heading to the pit- dark clouds on the horizon brought intermittent hard rain that kindly let up by the time we reached the pit floor. My interest for this trip was in the black shale, with hopes of finding shark material in particular. With the recent rains everything was muddy, and the black shale could be found in chunks strewn along the slumping highwall. Some folks were splitting the shale, but I did not have any luck with that-all of my finds were already exposed. The mud really made it hard to see whether or not there were fossils in the exposed black shale, but I was happy to be able to find a few pieces worth taking home- as often seems to be the case for me when fossil hunting, I found my best stuff in the first hour and virtually nothing the rest of the time I was there.

Its to my understanding that many Megalodon teeth come with Unfortunate modifications, in order to artificially boost price. My question on thus particular tooth is, does the root look reconstructed, or does it appear to be unmodified? I'll post more pictures if everything checks out.

Had a good time with my club yesterday when down at Batesford Quarry and got a nice haul for a first time down there. Not to many larger shark teeth in the piles but there were millions of regular fossils (mostly spines) but always a welcome sight to behold either way

Here is a selection of some of my finds from Sharktooth Hill near Bakersfield California. IDs would be appreciated.
