Jaekelotodus trigonalis ? from Kazakhstan, Mangyshlak,
Brett Breakin' Rocks posted a topic in Fossil ID
Hi There, I just wanted to confirm that I think (?) these are examples of the large Sand Tiger shark from the Chattian. Jaekelotodus trigonalis ? ... This time period is not one I'm yet familiar with. Though, it is in a similar area to where the O. auriculatus I just received was found. Mangystau (Mangyshlak), Kazakhstan The preservation in this area is poor but the teeth are much larger. You can see the cusps have been worn down/away @Al Dente Cheers, Brett

Hi All, I found these two teeth in Bracklesham Bay, Sussex, UK. After a good while looking at various websites I found a virtually identical tooth marked as Jaekelotodus trigonalis & this species is found at Bracklesham Bay however, I thought the teeth from this shark generally have two cusplets on either side? Other species from this site the teeth are similar to are Hypotodus Atlanticus & Hypotodus verticalis. I don't think it is Striatolamia macrota as there are no striations on the enamel / the cusplets are not scalloped... The height for each is roughly 2.5 cm, there are no serrations along the edges and the second tooth is curved upwards as shown in the second photo (would this difference be as one is from the upper jaw & one from the lower?). Just wanted to check if anyone collects the same species from other locations and could help me with the ID? Any suggestions greatly appreciated!!! Thank you. Richard
