From the album: Post Oak Creek
The famous "ginsu shark" is a rarer species that can be found here. This is a lateral position; a tooth farther back in the mouth. I've only found a handful and none are complete.-

Symphyseal teeth are found in the midline of the shark's jaw. They are usually small and squashed-looking. Since only a few rows produce these teeth, they are much rarer than other positions.-

The fossils in the creek can have varying levels of preservation: from the pristine glassy enamel seen at the top, to more river-worn seen below.-

These oysters are common in the creek, and support the Turonian age of the fossils.-

From the album: Sharks
An odd shark from the Cretaceous of North Texas - these sharks had crushing teeth suited for hard-bodied prey.- 3 comments

The "big guy" to find at POC. Though, this one is smaller, the preservation is as good as it gets for this location. In fact, it makes me believe that POC could draw from layers adjacent to the Eagle Ford Group. I've found matrix pieces that are consistent with the geology of EFG, but need to find matrix pieces with this kind of preservation to confirm Atco or something else. I'm also not sure that this is C. crassidens anymore since this smaller, narrower form differs so much from the holotype. I currently believe it's an undescribed species since I haven't found something that matches. Please let me know if you find a paper that fits this tooth (and the others at POC).-

Reconstructed tooth set from a "Crow" shark - Squalicorax (could be S. falcatus) - illustrating the variety of tooth positions. Anterior teeth have erect, triangular cusps. Lateral teeth and posteriors are more common and have an increasingly posteriorly slanted crown, resembling the teeth of modern tiger sharks.-

Lower anterior from the modern Great Hammerhead: You don't see many teeth from this location - they're hard to find (somehow, I found this one at night! It was on the beach right next to the hotel.).-

Rhinobatos teeth are probably the smallest teeth you can hope to find here - they are about as small as grains of sand.-

I found theses fossils 20 years ago or so, while visiting My Very Good Friends (and former house mates) in San Antonio Texas. I had brought a flyrod on the trip as I knew there were some creeks near their house and I wanted to spend sometime fishing them. One afternoon I grabbed my flyrod and a box of Wooly Buggers and walked the 3/4 of a mile to the nearest creek. as I was rigging the rod I started noticing the Devil's Toe Nails laying along the banks of the creek. I began picking them up as they looked pretty cool and I knew what their common name was. Fishing was pretty good as I caught a number of small Bass and a few species of Sunfish on the flies. I kept picking up the Toe Nails as I fished and soon had my pockets filled up with them. I stopped picking them up, but kept fishing for a few hours. returning to my friends' house I washed them off and dried them off on paper towels. they looked really nice after washing them of the dirt. I knew they were of Cretaceous age and I knew they are called 'Devil's Toe Nails" but I have never learned more about them. If anyone can Identify them for me that would be soo appreciated. Thanks for any help!, Dean ~~~

I found several well-produced and entertaining Youtube, videos about fossils and fossil collecting, many about Texas localities. A very articulate young lady, KOI, showed and asked for help to identify Texas fossils. The fossils in the videos are well lit, focused and have species titles with them. Check out here the video "300 Million-Year-Old Fossils..." at 11:58 into the video and at 4:15 into the Whiskey Bridge fossil video. See her videos: https://www.youtube.com/channel/UCE91a7T2yWjeZsRDo0pm-wg/videos Could someone who is signed up with Youtube help her ID her fossils or better yet ask her to post her fossils that need an ID on TFF. She would be worthwhile member. Thanks, John

Hi all, Am I on the right track here? Is this a Mosasaurus tooth? It was found in Iron Ore Creek in Grayson Co. Texas. Upper cretaceous, Austin chalk runs throughout this area of Grayson co. so believe it's within the same strata as Post oak creek in Sherman. About 15/16" long and 3/8" wide.
