Here is a Hemipristis elongatus (Snaggletooth Shark) jaw that I recently acquired. The jaw is 5.25” wide and 3.25” inches high. Here is the overall jaw: To better see tooth details double clique the below pictures. If you mouse over the pictures you will see the file name which has additional positional information. Hemipristis elongatus jaws must be weak at the symphysis because a lot of the jaws for sale have distortion to both the upper and lower symphysis. The identification and number of tooth files discussed below are based upon Compagno 1988. Hemipristis elongatus have both upper jaw and lower jaw symphyseal and medial teeth files. Upper jaw symphysis: Upper jaw symphysis showing two files of symphyseal teeth (blue) and two files of medial teeth (red): Lower jaw symphysis: Lower jaw symphysis showing two files of symphyseal teeth (blue) and two files of medial teeth (red). Note a partial separation of the lower jaw at the symphysis moved the teeth relative to each other and made it very difficult to show them: Hemipristis elongatus jaws have one upper posterior tooth file on either side. This jaw did not have a posterior tooth file on the upper right side. Upper jaw left side posterior teeth: Hemipristis elongatus jaws have two lower posterior tooth files on either side. Lower jaw left and right side posterior teeth: Hemipristis elongatus jaws have two upper anterior tooth files on either side. Here are the upper jaw A1 and A2 teeth left and right side: Continued in the next reply: Marco Sr.
