Today, I hunted for my 3rd time in June.. Once every 3 days is not bad, but I will be traveling North for 3 of the next 5 weeks... It will be more difficult to get out 10 times in June or July, so I make the most of every opportunity. It is also good exercise and I also need that... When I first started hunting, I would occasionally find a P. contortus. They were relatively rare in my sections of the Peace River. Every one I found , I would evaluate as aduncus or contortus. They looked like this and were almost always smaller than the numerous lemon, bull and dusky in the Peace River.. This was one of my best and has some colors. Most shark teeth in the Peace river are black blades with black roots. Also, this one has its serrations. Because it is Miocene Era, contortus teeth are generally worn smooth. x So, along with many other interesting fossils, I found a Physogaleus contortus while hunting today at a site that has more Miocene material than others I frequent. It is a pretty tooth, so I wanted to share.. So this makes me wonder if ALL 3 of the teeth I pictured above are indeed Physogaleus contortus and , if so, why did it take so long for me to meet the robust version of P. contortus? Maybe , in order to grow larger teeth, a shark needed to live longer and grow larger by eating more... and have less competition from Megs, GWs, Makos, Hemis, etc Could be other causes, comments always appreciated,, Jack

This specimen was found in micro matrix purchased from the Aurora, North Carolina Fossil Museum. Description: Teeth are very similar to the genus Galeocerdo with finely serrated, long, thick and warped crowns; pronounced notch, small serrations on heel of distal side. Undulating margin and fine serrations on mesial edge. U-shaped root with a prominent protuberance on lingual face and transverse groove (Fig. 5.10). Physogaleus contortus differs from the genus Galeocerdo in having very prominent and bulging root with the deep notch, and a much more erect crown in lateral view.

Galeocerdo aduncus/Physogaleus contortus artificial tooth set
bthemoose posted a topic in Member Collections
Below is my third artificial tooth set for an extinct shark, this time for the Maryland Miocene tiger/tiger-like shark(s) Galeocerdo aduncus/Physogaleus contortus. This adds to the artificial tooth sets I previously constructed for Striatolamia striata and Hemipristis serra. For this tooth set, I’ve presented G. aduncus and P. contortus as the same species, with the former contributing the upper and the latter the lower teeth in the dentition. The possibility that these species are the same is further discussed in a recent topic started by @WhodamanHD here; I relied on Applegate’s construction posted by @Al Dente in that thread as my model. In addition to being an interesting proposal, I don’t have the teeth to make a full G. aduncus or full P. contortus dentition (if they are separate species), so the combined approach was borne out of necessity! The largest teeth below measure about 7/8” on the slant. I haven’t yet found an upper symphyseal for G. aduncus so there’s a placeholder for that tooth in my set for now. These teeth were collected by me from Matoaka Beach over the last year or so. The full tooth set: Quadrants: Final with labels:- 5 replies
