Pathologic sand tiger tooth, most likely Striatolamia striata© bthemoose

From the album: Aquia Formation
Teeth of Striatolamia striata are by far the most common shark teeth found in the Aquia Formation. From the thousands I've collected, I believe some that I originally classified as Striatolamia striata may be Sylvestrilamia teretidens instead, based on the more triangular cusplets and other differences. That said, these could also just be variations within Striatolamia.© bthemoose

I have a single shark tooth from an Eocene Cook Mountain Formation location in Newton County, Mississippi. I would like confirmation or correction on the ID, please. My best guess is Striatolamia macrota, but I could easily be very wrong. Unfortunately about half the root is missing and I'm not sure whether a nutrient groove was present of not. The blade is clearly not serrated. Total height is a hair under 2.1 cm and restored width is estimated at 2.1 cm also. Any and all help would be appreciated. Here are three pictures to show the shape (scale bar divisions are cm): And here is one close up view of the one remaining cusplet: Thanks for looking. Mike

Upper Paleocene Lamniforms (Mitsukurinidae and Odontaspididae) ID from Chile
terminatordiego posted a topic in Fossil ID
Hello to all guys!!!, I would like to ask again for help in the ID of some teeth. I´ve been searching in a local university's museum for teeth of the original strata (Upper Paleocene), and I have found a very interesting set of boxes containing a bunch of different teeth, all labeled as "Scapanorhynchus sp.", maybe existing a missidentification. The question would be if any of you guys can ID the pieces and how to differentiate the Scapanorhynchus sp. from Striatolamia striata or Sylvestrilamia teretidens, the options I´m leaning for the ID of the teeth. I would also like to check if you guys @will stevenson , @MarcoSr or @bthemoose have any info about it. You guys are awesome!! The ruler is a 1mm step grid, and I'll try to order them from anterior to posterior (I am aware that each one can be of different taxa), all of them have a stronger or weaker folded surface in lingual side. Any help or info is welcome, thanks guys!!! and greetings from Chile. 1) 2) 3) 4) 5) 6) 7) 8) 9) 10) 11) 12) Finally, this one has the weakest folding:- 7 replies

***Need professional help with Paleogene/Eocene shark teeth identification***
Morte posted a topic in Fossil ID
Hello everyone!)) Need help of paleontologists and paleoichthyologists with identification of eocene shark teeth from Russia. I'm not professional, just a fan and rooky, so I choose possible species options for every tooth, according to books and scientific publications which I have. Hope I make right something at least. Be glad and thankful if somebody will help me figure it out)).- 3 replies

I recently purchased some more Moroccan fossils, including several shark teeth...I tried IDing them on my own, here are my guesses (scale is in inches; 1 inch = 2.5 cm), am I close? I don’t have much experience IDing Eocene teeth, so I’m not sure. Thanks!!! 1. Otodus obliquus 2. Cretolamna appendiculata 3. Cretolamna aschersoni 4. Striatolamia macrota 5. Jaekelotodus spp. 6. Brachycarcharias atlasi 7. Tooth I have no idea on (had cusps but they broke off) 8. Jaw bone section I have no idea on 9. Fossil I have no idea on

ID requested: Eocene shark teeth from Tielt Formation, Egem (Belgium)
ziggycardon posted a topic in Fossil ID
Hi everyone, today I arrived a small batch of shark teeth which came from the Egem Clay, Tielt Formation, Egem, Belgium that date back to the Ypresian, Eocene (53 mya). I attempted to ID them but as usual I would like to see what your imput is on my ID's. Tooth 1: Striatolamia macrota or maybe even Cretalamna sp. Tooth 2: Brachycarcharias lerichei? Tooth 3: Striatolamia macrota Tooth 4: Striatolamia macrota Tooth 5: Hypotodus verticalis or Striatolamia macrota Tooth 6: Odontaspis winkleri- 3 replies

Hi all, My wife and I often find these on the beach at Walton on the Naze, Essex, UK and have assumed that they are striatolamia from the extreme side of the jaw. Are we correct or are these a different species? Thanks in advance and apologies if I have used the wrong terminology. Best regards, Carl

Striatolamia Macrota with Pathologic Deformities found at Purse State Park MD
Gneave posted a topic in Fossil Hunting Trips
Before quarantine took effect, I had a chance to visit Purse State park. I normally frequent Brownie Beach, but the recent cliff collapse forced me to try some other spots. I was also interested in finding some much older fossils from the Paleocene formations along the Potomac. I found tons of turritella gastropod molds, and many smaller lamnid teeth. Some of the larger ones I found were pretty easy to identify as Striatolamia species, most likely S. macrota that had slight surface wear from being washed around in the Potomac. Most teeth from this location seem to be similarly eroded, and almost all my S. macrota specimens seem to be missing their telltale crown striations. I found some nice looking ones I found, all approximately an inch in length and with a hint of blue coloring. Towards the end of the trip I also stumbled upon a likely pathological lateral tooth, probably another Striatolamia. It definitely caught my eye, and I really liked the weird curvature of the crown. This one was about half an inch in length, and although it might not be easy to tell from the photo, it had a much stubbier tip that was not the result of chipping or erosion. Anyways, I just thought I'd share an interesting find from last month since I'm losing my mind in quarantine. It sucks not being able to go on hunts when the weather is so nice, but I hope everyone is staying safe. -
