I seem to be having a slow week at work, and didn’t have much at home demanding attention, so I decided to spend a day fossil hunting yesterday. I got up with intentions of checking out a new spot on the NSR, but when I looked at weather radar, there were showers in that area. The parts of NSR that I have seen are pretty tough to get into and out of when things are wet, so I changed my mind and made a drive to Post Oak Creek. One trip this spring was the only time I’d been there, and I didn’t know what to expect in mid summer, but it is one of the most fossiliferous places I’ve ever seen, so I was sure a trip there would be fun.

And just like my first trip there, I found teeth. I’ve found very few teeth of any kind in all the other places I’ve fossil hunted, so I really enjoyed my time crawling on knee pads, looking for teeth. I considered bringing my sifter, but decided I would just stick to searching the sand bars. It was a dark day for the most part, with light rain on and off, so not the best day for trying to spot tiny teeth on the sand bars, but I did find enough to really enjoy myself, and the clouds did help keep the heat from getting too bad.

The really small tooth in the upper left corner was the only Ptychodus tooth I found yesterday. Lots of the teeth are broken, damage from tumbling on the rocks, I guess. I always marvel at how sharp many of them are. Click the photos to be able to zoom in and get a closer look.

The number of bivalve and oyster fossils at POC just amazes me. They’re everywhere. I always have to pick up a few of the most beautiful ones. Look at the striking pattern on both sides of this bivalve.

This little bone caught my eye. It looks like a femur from some kind of small creature. The thought in The Fossil Forum is that it’s from a turtle.
