I found this tooth at Calvert Cliffs, Md. The root looks to thick to be a Bull shark. A small Mako is my my best guess. Does anyone know?

We found this shark tooth fossil and wondered what type of shark and how old it could be. This was found on Casey Key beach FLA.

Hello dear forum participants. I present to your attention a tooth that has caused some discussion among us. The main version is that this is a rounded Physogaleus tooth, but in appearance it seems that its roots are not broken. Curious to know your opinion. The tooth was shown to specialists, and there is literature on our regional sharks. It appears to be Physogaleus but would like more clarity. Age: Upper Eocene, Middle Urals Thanks for your attention Question - if there are new questions and findings, is it possible to continue posting in this topic or is it better to create a new one based on our findings, if, of course, the reader is interested? Best regards, Anton.

Hello again! Yesterday’s finds we’re another learning experience but I AM learning, so here goes. Wife found this today on Venice Beach in Florida. It was deposited more-less at our feet by a wave (it’s choppy today.) I think it looks more like somebody dropped it and it’s a fake. Any thoughts? measurements in centimeters.

Hello everyone Couple of unusual finds for me from diving in the Cooper River, near Charleston, SC. This river cuts through Oligocene to modern deposits so it can be tough to ID finds. The first looks like a Castoroides sp? broken beaver tooth? The shark tooth has a U shaped root, no serrations on the blade, and has cusps that appear to have a gap between the root and blade. Looks like a cusped P. Benedeni or possibly an upper lateral sand tiger (based on looking through elasmo.com). Doesn't look like an O. Angustidens or A. Grandis to me? I've seen a few cusped Benedeni's identified on the forum and was curious if that is what I found Thanks for looking

Hi All, I'm very new to the world of fossils and already have a question... This fossil was found among the rocks on a beach in Anglesea, Wales (UK). From trying to research, my best guess is otodus obliquus (upper L8/L9) going off crown size. However, I can't find any info about finding these in the UK - all the ones I've seen similar are from Morocco. Is Anglesea a possible location for these sharks or is my ID way off? Thanks in advance!!

Dear all, For as long as I can remember, I’ve always been interested in fossils. I am originally from the Netherlands but I grew up in the South of France. As a kid, you could always find me in the old abandoned quarry near to our house, looking for ammonite & sea urchin fossils on a heap of old stones! I am now 30 and I have moved to the Dutch Caribbean for work. Not having looked for fossils for about a decade, I decided with a friend to have a go at this old hobby of mine on a Sunday, on a spot rumored to feature loads of nice fossils. After 2 hours of searching and not finding jack and having been chased by a pack of wild dogs we decided to return home. But on our way back, on a spot that seemed interesting, we decided to have a final look and managed to find a whole heep of shark teeth. About 40 of them! I am very curious whether some shark teeth enthusiasts would be able to identify the species of sharks that once shedded these shining beauties! Especially the larger ones! Could they have been from great whites? or perhaps the Otodus sokolovi? Friendly regards, M.

A shark tooth from my collection: a Cretalamna maroccana specimen
gond posted a topic in Member Collections
Hello everyone, it's been a while since I last posted on the forum In the last year my collection has reached 33 specimens, so I guess that "road to 35" is extremely close! Today I wanted to show you a specimen I acquired very recently, specifically last March! Species: Cretalamna maroccana (Arambourg, 1935) Size: 2.5 tall, ~3.0 cm long Age: 72-66 mya (Late Cretaceous, Maastrichtian) Origin: Ouled Abdoun basin (Morocco) About this fossil: a nicely preserverd shark tooth, with only a small hole on the front part of the tooth's root; I especially appreciate the two lateral cusplets, which are extremely nice to admire. Definitely one of my favorites!- 8 replies

Hi there, I recently received a large modern mako tooth that has a silver cap attached that is glued on, I would like to remove the cap and the glue but unsure what the best way without damaging the tooth or root in the process, see photo attached

These are photos of some, what I assume are, teeth, that were in a specimen tray containing many well-known forms of shark teeth in an old collection. None of the pieces were labelled or had a locale. These have me stumped. I've googled "leaf-shape, paddle-shaped, flat, weird, unusual, shark, and odd teeth" with no success. Can somebody please help? Maybe they aren't teeth at all?

The dentition of Centrophorus sp., a group of deep sea sharks
Dino9876 posted a topic in Member Collections
The genus Centrophorus sp. represents a very interesting group of sharks within the Centrophoridae (Squaliformes), which can be found up to about 3000m below the sea surface. The largest representatives of this group reach a body length of 170cm. Not only because the sharks of this group are among my favorite sharks, but also because fossil finds of this species are extremely rare, I decided to write about this topic and compare fossil and recent Centrophorus species with each other, as well as collect the known information about them. The modern genus Centrophorus has been repeatedly revised, rewritten, rearranged, species synonymized and added again in recent years, which makes it difficult to keep an overview. According to my count, the genus currently includes a maximum of 17 described species and is distributed in all deep-sea regions worldwide. The 17 known modern Centrophorus species are: C. acus (synonymous with C. granulosus according to White 2013, but still often considered independent), C. atromarginatus, C. granulosus, C. harrissoni, C. isodon, C. lesliei, C. longipinnis, C. lusitanicus (probably a cluster of different species), C. machiquensis (doubtful), C. moluccensis, C. niaukang (synonymous with C. granulosus according to White 2013, but still often considered independent), C. seychellorum, C. squamosus, C. tessellatus , C. uyato, C. westraliensis, C. zeehaani The fossil records are limited to 3 species, Centrophorus granulosus, squamosus and primaevus. They appear from the late Cretaceous (Haumurian) or early Paleocene (Keyes, 1984). It is possible to distinguish different species based on their teeth, but in many cases it is very difficult, especially without locality data and due to the lack of and contradictory information. I would like to show you the teeth of 9 extant Centrophorus species from my collection and the 3 known fossil species. I would particularly like to focus on their teeth, as they are almost the only thing that can be detected as fossils and also what is most likely to get from the recent species. Since my English is unfortunately not good enough to describe the tooth shape perfectly, I will let the pictures do this The tooth formula describes the number of teeth in the upper and lower jaw. I have summarized them myself from the literature for most of the species, since there were often different numbers to be found. Centrophorus squamosus Is one of the largest representatives of this group (up to approx. 170cm) and is distributed worldwide. It can be found down to a depth of 2400m. The fossil record is currently limited to New Zealand (Keyes, 1984). Tooth formula: 30-38 / 24-32 Keyes, 1984 (fossils, found at different localities in New Zealand): Extant teeth/ jaw from my collection (35 / 30; 15x12cm): Centrophorus primaevus Extinct representative of this group (lived in the Late Cretaceous, Santonian). It is a relatively small representative with a body length of approx. 0.5m (previously known). Tooth formula: Unknown The fossils shown are from Lebanon (Kriwet & Klug, 2009): Centrophorus granulosus Also a large representative of this group (up to 170cm). The species is distributed worldwide, but not in the Mediterranean where it is replaced by C. uyato. It occurs to a depth of about 1500m. The fossil records are currently limited to France (Ledoux, 1972). Tooth formula: 36-43 / 28-32 Ledoux, 1972 (fossils from France): Ebert & Dando, 2021: My collection (39 / 30; 9x8cm): However, most fossil Centrophorus teeth found in publications are not assigned to a specific species, but only as Centrophorus sp.. Here are a few sample images from various publications: Mannering & Hiller, 2008 / Schutter & Wijnker, 2012: Below I would like to post pictures of the remaining extant Centrophorus species. Unfortunately, for some species the information is very scarce and, as I said, often contradictory.- 12 replies

Holden Beach, NC in the middle of Myrtle Beach, SC & Wilmington, NC if you went along the coast. Conflicted on this ID due to the possible serrations on tooth and cusps. Is that wear/damage or legitimate serrations? Additionally, I'm having a difficult time determining if Serratolamna or Cretalamna had serrations? Anyone else have an accurate ID with these photos?

Found this at Carolina Beach. It’s the same color and texture as another confirmed shark tooth that we found and it has a triangular shape but it’s missing that top ridge part so I’m unsure if it is a shark tooth or not. If it is, is it possible to ID the kind? Thank you!

I could use some help in identifying this very small shark tooth I found in a brook in Monmouth County, NJ. I am thinking that it could be an anterior tooth from a baby Goblin shark (Scapanorhynchus) because of the deep nutrient groove and the slight curvature of the tooth. However, it's very skinny with a very long root and the striations do not appear to continue onto the root. It stands out from the many Goblin Shark teeth I found so far, and I am not 100% sure what it is. Perhaps it's a small symphyseal tooth from a goblin shark? I am still learning to properly ID these things and could use confirmation from someone who is better at it. Thank you in advance.

Hello, I hope all is well. I'm looking for some help with ID'ing two items I found on North Myrtle Beach (between 13th and 15th avenue's). The city is in the process of building a new drainage system around 18th avenue that extends out into the ocean (kind of looks like a pier). So there a a fair amount of offshore digging going on. I looked around on the web, a few other resources and a book and couldn't come to a conclusion on the ID for these items. One is a sharks tooth (#1 is the front with ruler for size, #2 is the back, #3 is the front a little closer)...I'm thinking maybe Dusky. The other is a bone or possibly turtle (#4 side view, #5 is the back, #6 is the front, and #7 is with a ruler for size). Any help you can provide would be greatly appreciated

I’m still fairly new to shark teeth hunting/ID (started a couple of years ago). I think this is a shark tooth, but I’m not 100% because it’s hollow/missing root. However, I’ve read a few other threads on here about hollow shark teeth, so I understand it is possible. Assuming this is one, I’m curious if anyone can help me ID it? (And of course, if you think it’s not, please let me know too) I found it today near Swansboro, NC. My identification book makes me think maybe Mako, but it also says those are pretty rare in NC. Thoughts? ps- I’m new here, so please be kind, but let me know if I’ve made any mistakes with forum rules/etiquette. Thanks so much!
