From the album: Post Oak Creek
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. -

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 trilobite, or an impression of one, but as it is the same color as the stone surrounding it, it just doesn’t seem to be right. I could use some knowledgable help. My guess is a ptychodus tooth - but I am way out of my depth here Thanks

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.-

Tooth of P. whipplei. Collected 6/21/19. -
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!!!

Recently I started looking a little more closely at the small gravels in the creek. This little Ptychodus tooth, the smallest I've found to date, is the fifth I've found in Austin. I've reviewed the pinned topic on Ptychodus, but can't nail down the ID from there. What do you think?
