I’d like for my Post Oak Creek collection identified (specifically the shark teeth), but I can’t find much information online about the species of shark whose teeth are found here (Post Oak Creek in Sherman, Texas). When I HAVE come across general information about the creek and other peoples findings online, there aren’t any pictures of the teeth or nobody else knows exactly what they have. It’s also hard to tell if I’m grouping them correctly, so I apologize if I’m mixing some species together. The longer teeth have very similar characteristics, but greatly differ in size. And the only teeth

I’ve decided to post this one separately. Very unusual composition. If you watch the video, you’ll see that light refracts off of tiny crystals in the center of each segment (which I’ve circled in red in another image). It’s hardly noticeable. The specimen is very smooth and rounded. Another member said in a different post of mine that it could possibly be an inoceramid hinge, though my own research resulted in nothing. I can’t find anything online that remotely resembles my specimen (inoceramid or otherwise). I found it at Post Oak Creek in Sherman, Texas. FullSize

Hello again forum! Remember that bucket “goodie bag” I took home from the torn up Post Oak Creek a few months ago? I finally went through it and found some excellent stuff! (Im actually wow’d with some of this stuff because I’m just an amateur!) Surprisingly- I found tons of other stuff that ARENT shark teeth for once! I grabbed a 5 quart bucket and took a big shovel scoop of gravel/mud from various parts of the entrance of the creek where the construction was and some from the first sandbar. Im working on an educational frame display I might actually eventually donate (there IS

This is a Cretaceous oyster that I found in Post Oak Creek in Sherman, Texas. The oyster has traces of a yellowish calcite-cemented sandstone found in the upper part of the Arcadia Park Formation of the Eagle Ford Group. "Pediformis" in the name, Ostrea alifera var. pediformis, means foot-shaped or pediform because the oyster looks like a foot or boot. In Hill 1898, the author eliminated the Ostrea alifera Cragin, and Ostrea alifera var. pediformis Cragin names because he considered them to be Ostrea lugubris Conrad. I disagree with Hill's decision because my oyste

As it looks like I won't be able to make it back out to Charleston for quite a while, I was wondering what the fossil hunting scene looks like here in Texas. I've heard that there's some miocene material to be had around Galveston and Bolivar, and I've heard about the Eagle Ford Formation and Post Oak Creek, but I haven't come across a whole lot of information. I do know there are some invertebrate fossils along the Brazos, but I'm not super big on snails. I'm in the Houston area, so a day trip down to the coast is definitely feasible, but I need to do some more research before I commit to mak

As usual, we found the usual shark teeth in Post Oak Creek in Grayson County, but I’m unsure about this tooth. I’m very new at this, but it doesn’t have a flat backside like the typical shark tooth that we find, but it is almost a perfect oval shape. Any help is greatly appreciated. Have a great day!

Left: Lissodus sp.; right: Onchopristis sp. These are so rare, don't even bother looking for them. Lissodus is a Hybodontiform shark more commonly found in freshwater ecosystems (guess it also tolerated salt water). Onchopristis is a sawskate, but a rarer genus at this locality than Ptychotrygon. -

The shell of a "foram" (test). It looks like a snail or ammonite, but is actually a marine protist (only found in the oceans). -

Rhinobatos teeth are so small they make me angry Here you see a dozen guitar fish teeth sitting on the face of a dime! The largest is a bit under 1 mm tall. R. incertus has a pointed crown, R. caseiri has no point. -

This is a septarian concretion from POC. It's about the size of a good strawberry. Collected 9/28/19.- 2 comments

I'm pretty sure these are S. raphiodon teeth. They are much smaller than S. texanus with a narrow main cusp and finer striations than S. texanus. Compare: http://oceansofkansas.com/sharks/Kansas/shscap3.jpg -

I'm fairly certain this is a posterior Cretodus - a shark known for producing Texas-sized teeth! At just 1 mm tall, this may be the smallest Cretodus tooth possible. -

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. -
