PaleoNoel Posted July 2, 2018 Share Posted July 2, 2018 I think 12 and 13 likely come from the Porbeagle Shark, either Archaeolamna kopingensis or Cretolamna appendiculata. 1 Link to comment Share on other sites More sharing options...

I'll defer to others for the teeth. Thank you! I’ll try to post the ones that are hard to determine in clear, different, and better angles Link to comment Share on other sites More sharing options...

PaleoNoel Posted July 2, 2018 Share Posted July 2, 2018 I believe #5 is a chipped Goblin Shark tooth (S. texanus). 1 Link to comment Share on other sites More sharing options...

Looks a lot like a mosasaur tooth by comparing in the two comparison pics When compared to the mosasaur tooth from Fossilguy.com it looks really similar so I would assume its a partial tooth from one. 1 Link to comment Share on other sites More sharing options...

The Jersey Devil Posted July 2, 2018 Share Posted July 2, 2018 #1 is a gastropod. #2 is a steinkern, probably a gastropod steinkern. #3 looks like a steinkern of a bivalve. #4 is a Squalicorax lindstromi tooth. #5 is an anterior Scapanorhynchus texanus tooth. #6 is a posterior Ischyrhiza mira rostral. #7 is not a tooth, but rather a belemnite (Belemnitella americana) phragmacone. #8 and #9 are concretions. #10 is an Enchodus sp. (most likely E. petrosus) palatine tooth. #11 is an S. texanus upper lateral. #12 is a Paranomotodon angustidens lateral. #13 (left) is an Eostriatolamia holmdelensis anterior. #13 (right) is an Archaeolamna kopingensis anterior. #14 is an S. texanus (a shark) anterior. #15 looks like a Paranomotodon angustidens anterior, although there is a chance that it is an A. kopingensis (picture does not show the root area well). #17 is an I. mira partial root base. #18 (first two photos) are an Enchodus gladiolus tooth. #18 (third photo, which seems like a different tooth) is an E. petrosus lateral tooth. #19 is a modern seed. #20 is a very worn shark tooth, possibly P. angustidens. #21 is a modern nut (it is one of those nuts that squirrels like to eat, whatever you call them). #22 is a concretion. #23 is a crocodile tooth. #24 (2nd #23) is a gastropod steinkern. Your #24 is an Enchodus petrosus palatine tooth. #25 is a Choristothyris plicata bivalve. #26 is a partial Mosasaur tooth. 3 “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...

Masp Posted July 2, 2018 Author Share Posted July 2, 2018 @josephstrizhak any guess as to what type of crocodile the tooth could belong to in pic #23 and it’s a juvenile sp. correct?

The Jersey Devil Posted July 2, 2018 Share Posted July 2, 2018 @Masp No problem with the IDs. The Croc tooth is a great find for only your third trip there. It is likely a Thoracosaurus neocesariensis tooth, but you can't be 100% sure because the reptile material is pretty fragmentary here. It is probably not a juvenile tooth. The Mosasaur tooth looks like Mosasaurus conodon, although you can't be definite when it's just a piece of enamel. 1 “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...

The Jersey Devil Posted July 3, 2018 Share Posted July 3, 2018 Hi @Masp, Can you make a couple pictures at different angles of #15? I would like to confirm if it really is a thresher. Btw, I did not add that #1 is technically a gastropod steinkern.

non-remanié Posted July 3, 2018 Share Posted July 3, 2018 I'd say not a Paranomotodon, but more likely a broken Archaeolamna. Picture isn't definitive. The sand tiger is probably correct but the last one is definitely Cretalamna not Archaeolamna.

The sand tiger is probably correct but the last one is definitely Cretalamna not Archaeolamna. I somehow can't really see the first one being a broken Archaeolamna upper lateral. The root does seem fairly whole in height, which means that it is not robust enough for Archaeolamna. I always thought the morphology of the last tooth matched with a Cretalamna lower third anterior, but this pic always made me second guess that thought and think it's an Archaeolamna: http://fossilsofnj.com/NJfavorites/album/slides/ct_b1_rs_opt.html I thought the ID on that link was wrong and should be Cretalamna, especially because of the cusplets and fairly flattened shape. Would you say that tooth is actually Cretalamna (probably a lower a3)?
