I realize that a lot of my in situ shots are of ptychodus, but they seem to be more visible and photogenic. Taken 12/31/19.-

Tooth of P. whipplei. Collected 6/21/19. -
I recently took my 9-year-old daughter hunting at Post Oak Creek in Sherman, TX. We collected these about 200 meters upstream (NW) from the S. Travis Street Bridge. While she did not enjoy the bugs and frogs, we both had a blast finding shark teeth and other cool stuff. It was our first trip fossil hunting and I am complete uninitiated in identification. Can you guys take a look at these and let me know what's a fossil and what's a pretty rock? Trust me, she will be perfectly happy if they are all just pretty rocks. Besides what's pictured, we found about a dozen shark teeth and en

Stethacanthus + other shark teeth for trade
fossilsonwheels posted a topic in Member Fossil Trades Bulletin Board
We completed our first trade on the fossil forum recently and it was awesome. We got a great fossil and a cool new friend. I am putting up one of my Stethacanthus altonensis teeth because I want to bulk up our shark education program just a bit. It is really the only tooth we could trade that has much appeal. Here are the details on the teeth we have to offer. I actually think this one of our anvil shark teeth. This one is smaller but has the tip intact.

Our Shark Education Program- The Ginsu and The Crushers
fossilsonwheels posted a topic in Member Collections
Our last post ended with goblin sharks and the next era up in the presentation is one of my favorites. We get to the large sharks of the Cretaceous. This is also where the adaptations get more specific and where the science gets more heavy duty for the kids such as discussing regional endothermy. I am a firm believer than you do not "dumb down" complicated science to elementary students. You simplify and explain, you do not dumb it down. First up are the giant crushing sharks, Ptychodus. We present both P. mortoni and p. whipplei though most of the discussion is about mortoni. The- 4 replies
