Hi! This shark tooth (?) was found along a Delaware, USA beach. Though I do find great joy in finding fossils/artifacts, I am not a hunter, nor do I have any knowledge of this type of thing. What I know: - Found in Delaware, USA on the sandy shoreline of the beach. - It is about 4cm (~1.5 inches) at the top. - Photos below! Can you tell me: - Who this belonged to? - How old it is? Thank you so very much! front front back

Hi All I found my largest shark tooth this past weekend here in New Zealand. I thought it was a Great White at first but a few people have thought it might be a transitional one. I was wondering if one of the shark tooth experts could have a look and let me know their thought Here is a bit of video of it as well: https://youtu.be/U-i8W2aOtLE?t=373 Thanks!

The first Megalodon for a Chinese enthusiast
15652353758 posted a topic in Is It Real? How to Recognize Fossil Fabrications
A brief description of the situation. It looks nice on the front, very structured. Over five inches long on each side, beautiful V-shaped. The disadvantage is that one side of the serration is damaged, and the root of the back tooth is slightly corroded? There are fossilized shells on the tooth roots? …..🥺 -
Hi everyone! After more than 7 years of putting it off, I finally returned to Green Mill Run last weekend. There were lots and lots of giant Exogyra in the creek, which was interesting since I’ve never really seen trip reports mention those; not sure if something happened to bring them all there. Especially since I assumed most of the Cretaceous stuff in GMR is washed from upstream, but I can't see so many of those big shells being washed all the way to the same spot. But anyways, here are some fossils I’d like an ID or a clarification on! Ignore the ruler pattern haha Burrow casts? There were a few of these, they looked rock-like but with a unique weight and texture, and they were colored differently from the usual black GMR fossils Hybodont clasper? I know most/all of these are Squalicorax, including this absolute beast here, but any idea on species? C. hastalis? Brachiopod? Some kind of shark teeth but not certain about species Either goblin or sand tiger? Bryozoan? Thanks everyone!

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?

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?
