Following up on the artificial tooth set I recently constructed for the Paleocene sand tiger shark Striatolamia striata, I decided to see if I could put one together for the Miocene snaggletooth, Hemipristis serra, using teeth I've collected along the Calvert Cliffs in Maryland. I haven't found a great resource for an H. serra dentition, but I consulted a few different sources to get a sense for the arrangement, including Fossilguy.com, J-elasmo (which has a dentition for the extant H. elongata), and various TFF threads. The resulting tooth set is below. While I've found quite a few H. serra teeth, their abundance from the cliffs isn't anywhere near that of S. striata from the Potomac River, so this one was a bit more challenging to construct. In addition to several fairly worn teeth in my set, some that I've slotted into various jaw positions are likely a bit more fanciful than the last one. The best extreme posteriors I've collected are proportionally too large, so I also had to use less good substitutes for those positions. The largest teeth below are about 1.25" inches in length. Most of these were collected from Matoaka Beach over the last year, but I found a few of them from Brownie's Beach and Calvert Cliffs State Park. The full tooth set: Quadrants: Finally, here are some better examples of extreme posterior teeth. Both of these are a tad over 0.7" long.

I did not find this one - it came from Harry Pristis. But it's in my collection! -
This hemi’s shorter side is longer than 4 cm, about 1.6 inches. I think it might be longer than 2 inches if the other root lobe is still there, so I used the clay trying to figure out the original size of this tooth. The results is almost 2, but I’m not sure if I doing it right?

Need some help confirming what type of tooth this partial specimen is. I found it along the Potomac in Virginia. I think it is a snaggletooth, but something seems weird about that diagnosis. Thanks!

Made my first fossil hunting trip to South Carolina, went to some areas around Summerville, thought I’d share pics of some of the fossils I collected! The best finds were some echovenator-like teeth, Angies, great whites, some intact sections of dugong ribs, and several associated pieces of a sea turtle shell. Felt like Indiana Jones exploring all the creeks trying to find productive spots haha. Fun trip, hope to return in the future!

Extant Hemipristis elongatus (Snaggletooth Shark) jaw
MarcoSr posted a topic in General Fossil Discussion
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.
