Hello, first time poster - long time admirer. I moved to a new place and have been walking over this every day while getting exercise. What is it? KC Group, Middle Zarah Subgroup, Wyandotte Formation, Quindaro; aprox 4cm across at widest. This is in Kansas City, once the fringes of a great inland sea - so shallow marine fossils abound! It is located on the top edge of a natural bluff, enhanced by being an interstate highway cut, and is actually on the floor of an old stone quarry from the 1940’s - hence the probable erosion. At first glance I thought it the thorax of a

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. -

One of my favorite teeth to find, Ptychodus was a large shark that likely feed on hard-bodied animals like shells, crustaceans, or maybe ammonites. Most of the teeth here are from P. whipplei but there are a couple that could be P. anonymus. -

I found less stuff than last time, but I found a nice centrum and a shard of a mosasaur tooth. A couple teeth grouped with Scapanorynchus may be Serratolamna sp. -

Large shark teeth including cretoxyrhina, cretodus, and ptychodus. (The left ptychodus would've been massive had it been complete.) Scale bar = 1 cm. Collected 7/18/19. -

This came from the bottom of the Eagle Ford formation in Texas, could even be the top of the Woodbine formation. Ptychodus lattisimis? last pic for scale

So in my few months of collecting, I’ve really found my favorite tooth to collect is the Ptychodus. Not sure if it’s the fact that it’s a shark tooth but not your normal sharp at a razor style, or just because they are all so different. I am really wanting to start just a collection of Ptychodus teeth. In the mean time, I want to live vicariously through everyone else. I really wanted to start this topic just to see who has the biggest one out there in fossil land! So if you all don’t mind, please post!!!

Our Shark Education Program- The Ginsu and The Crushers

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

I purchased some Ptychodus teeth and I can not determine the exact ID on my own. They are smaller than P. whippeli or P. mortoni teeth I have and bigger than the single P. anonymous tooth I have though that is the species I originally though, and still think these are. They are from the Kamp Ranch section of Eagle Ford in Texas. I consulted a very well put together ID guide here but am still just not sure what I have, other than nice Ptychodus teeth lol Any help would be appreciated.

So my 8 year old son and I did our first ever trip to go find fossils. Attached is what we found in our very untrained 2 hour trip! Haha I literally have no experience outside of reading on this forum from time to time. We may have just picked up some rocks but they looked like fossils to us. I know most most of the teeth are probably goblin and I believe we found 2 Ptychodus. The main things I’m wondering about are the long piece slim piece next to the Ptychodus (possible whale tooth?), two vertebrae looking pieces, the egg shaped piece, and the white piec

We just started hunting for shark teeth in August and have found many, but finding the ptychodus teeth is my favorite. I just wanted to show you guys our collection of them so far. Are these all whipplei?

I found this Ptychodus marginalis on a sandbar on a river this spring after a large flood. The river cuts through the lower Smoky Hill Chalk of Northwest Kansas. After I picked it up, I asked myself "is this real?" It is!!! 54mm across.
