Hi all, I'm hoping some of the resident experts here can help confirm or correct my IDs of the three fossil shark teeth and what I believe is a cetacean lumbar vert shown in the pictures below. I found these recently on a beach along the Calvert Cliffs in Maryland (Miocene exposure). Thanks for your help! For the shark teeth, I believe the the two on the left are both Carcharodon hastalis (though am more confident in my ID for #1) while the one on the right is possibly Isurus oxyrinchus though may also be Carcharias sp. All three have worn roots so I realize that may complicate the IDs. See pictures further below for scale bars and labial and side views of these. From pictures online, I believe this is a cetacean lumbar vertebra. The "bumpy" surface in the two lefthand photos also signifies that the epiphysis is missing, and thus this came from a juvenile, correct? Is it possible to further identify this as from a particular species or genus? Thanks in advance for your help!

I found these teeth years ago on Kure Beach, NC. They are pretty worn so I know an ID may be tough if not impossible. Please let me know if I need to provide any closer images and/or any additional information. I’ll number these 1-5 from left to right to make it easier to discuss the individual teeth.

Hello All, I am brand new to finding Fossils. I usually go along the beach to find shark's teeth but we went to Gainesville a week ago and found a ton of cool fossilized teeth including a few dolphin teeth. We are now hooked and my wife has been making artistic creations with the teeth we found. I know some people do not like that but it is a way that my wife gets involved and she is my best friend so it is so cool that we are doing something together. We are going again next week to find more!

Hi, I’ve been working on my project for a while now and I’ve decided to ask everyone to show there Alberta Tyrannosaur fossils! And if it’s teeth would you be able to put the Mesial and Distal serration count over 2mm. Thank you!

Hello, I was doing a study on the T. rex and Nanotyrannus teeth specimens I had, and I wanted to compare them against a list of known T. rex teeth with measurement. The paper: Dental Morphology and Variation in Theropod Dinosaurs: Implications for the Taxonomic Identification of Isolated Teeth (JOSHUA B. SMITH, DAVID R. VANN, AND PETER DODSON) contains a list of 115 T. rex teeth. To make it easier to compare and read the data, I combined the measurements into a single chart, added colors and lines for ease of reading, and added the size and names of the T. rex used in the study Feel free to refer to the below chart for T. rex teeth measurements. I had to split the chart into 2 due to size limitations, but if you want the full-sized PDF version (25 MB), please message me so I can send it to you by email. If you have any suggestions to improve readability, or have your own data to add, go ahead and post it here! I will be posting pics and measurements of my various T. rex and Nanotyrannus teeth here @Troodon

Show Us Your Wide Boys! A Thread For The Widest And Fattest Megalodon Teeth
Kurufossils posted a topic in Member Collections
Heres a fun thread for those to show off their widest and fattest looking megalodon teeth fossils in thier collections. I'll set the tone with the widest fat boy in my collection, I don't have digital calipers but it measure roughly 5.4 inches wide by 6.1 inches long. When I close my hand together it looks even more monstrous. Share yours and join the wide boyclub Got the idea while thinking about what the widest megalodon tooth ever found measures, if anyone does know do share in this thread!

The teeth below are said to be dinosaur teeth from Liaoning, China. Are they dinosaur teeth or teeth of marine reptiles?

Found these teeth with a bunch of other items on a lake beach today. Anybody know what they could be? I have some modern sheep, horse and cow teeth. None of them compare, I do not have full sets of teeth to compare either. These ones are much harder and wiegh much more than the ones I have. Any ideas?

Hello all i believe these are both mosasaur teeth but wanted confirmation by folks with much more knowledge. The bigger of the two is 7/8 inches long thank you for your help

I'd quite like to add a new theropod tooth to my collection. I saw these three for sale, just wondering if they are Nano/theropod as described and not, say, raptor teeth. Thanks Pictures 1 - 3 is 0.56 inch. This has a more oval base, does this mean it's not nano? Because aren't there teeth more rectangular with an indented middle? Pictures 4 and 5 is 0.47 inch -- No pictures of base for this one. Pictures 6 and 7 is 1.06 inch long, but has a repaired tip and is in matrix. Any help will be great. If they check out, I will select one of these. If not, I'll have a browse for some others.

Hello, These three teeth were found at a land site in Manatee County, Florida. They are a bit beat up, especially the third one, but hoping an ID is still possible. Thank you very much for looking. Cheers, Marie

A selection of Mosasaur jaw and teeth
FF7_Yuffie posted a topic in Is It Real? How to Recognize Fossil Fabrications
I know these are often composited, but if anyone can have a look, see how these are, that wpuld be great. I intend to get 1 globidens and one Mosasaurus Anceps. Ancepz I will put on post 2 1 - 15cm long from Benguerir 2 - 12 cm long --the different shading at the root, is that a sign the teeth are added? 3 - 10.5 cm

Yesterday I received a parcel from a member of the forum, containing fish and plant fossils from the Scottish coal measures, as well as a tooth which I found in West Yorkshire (UK) and sent to be prepared. My favourite of the Scottish fossils is a tooth which I am fairly confident is Strepsodus sp. Since little is known about Rhizodont teeth, it’s often very difficult to put a genus name to a particular species. Despite this, when I first saw this tooth the shape immediately made me suspect it is Strepsodus, so I decided to have a closer look at the striations. I was pleased to see that the striations look a very good match to Strepsodus sp in my opinion. I am therefore about 90% sure it is Strepsodus, and it’s the only tooth in my collection that I would call Strepsodus with any confidence. Sorry for the low quality photo, it’s quite small (5mm) and the shiny surface made it difficult to show the detail. Here is the tooth from West Yorkshire, before and after prep. It measures 12mm long, and is the largest tooth I have found in the Yorkshire coal field. It also the best preserved coal measures tooth I have found. This tooth comes from a mussel band, in which fish remains are quite rare, apart from in very thin fish layers which sometimes occur in the band. However, this is not within one of the fish layers. I’m not sure what fish this tooth is from, I suspect an identification would be almost impossible until more information about these fish is discovered and published. It is from the Pennine Lower Coal Measures formation (upper Carboniferous).

Hi there! While looking for shark teeth, in southern Iberia, we found this strange fish teeth(?). Any ideas?
-
Found these in alluvial sediments on the Eastern Shore of Maryland. They are silica but very odd shapes, almost look like teeth. Anyone have any idea what these are? Are they fossils or just oddly formed silica?

Hello everyone, found this mysterious tooth in a cretaceous stream in New Jersey. Haven't come across any similar or anything I can really compare it to, plus its kinda worn. Which doesn't help but the leaf-like shape alone is very interesting, hopefully this one can be figured out.

Found these two teeth still attached to a segment of jawbone on the Brazos River just southwest of Houston today. They're definitely mineralized, so I believe I can rule out ordinary cows. However, after doing some research online the teeth seem to be much too flat to be bison, so maybe horse? They both look like molars, although one of the roots is broken off of the first tooth - I honestly have no idea how it managed to hang on for so long. Either way, I was incredibly excited to find this, especially after braving the 90 degree plus heat for several hours without sunscreen. Any help on an ID would be much appreciated. Thank you!

9This is my shark tooth collection. Thought it would be cool to share here. My collection is a very small one, and is nothing compared to what some people have, but I am quite proud of it. (Image is in reply below)

Hi guys! I’m new to this, but my wife and I have been shark tooth hunting for the past month thanks to “quarantine”. We have found some interesting things, but can’t seem to pin point what they are exactly. We believe some may be megalodon teeth, great white teeth, and a dugong bone. All were found at Onslow beach,NC. We appreciate your guys help!
