Yesterday morning I drove to Grayson County and hunted yet another new spot in a creek. This one did not disappoint. With the extended drought (though parts of Grayson County did get a half inch of rain later in the day yesterday), I keep wondering how these creeks aren’t picked clean, but I’m still finding fossils. Here are a few as they lay. Click on the individual photos to be able to zoom in for a closer look.

Here is what a picked up. There are 124 teeth, but no Ptychodus teeth. It’s funny how hit or miss finding Ptychodus teeth seems to be in these creeks.

I think this a piece of a sawfish rostral tooth. I also found one of these my last trip, but didn’t recognize what it was.

I think this little guy is my favorite tooth from the day. I uploaded the other individual tooth photos from the day into this album.

And then there’s this rock. Here are views of both sides. I had to ask in The Fossil Forum what this was. It’s branching bryozoan, that attach themselves to oysters, it turns out.

I’ve had so much fun hunting teeth in Post Oak Creek that I decided to try some of the other creeks in Grayson County. Last week’s visit to another creek didn’t produce much, but today’s new spot had lots of interesting finds. Like Post Oak Creek, this one is Austin Chalk on maps, near the Eagle Ford boundary. Here are a few finds as they lay. There are two teeth in photo 2. Photo 4 requires a close look. Click on the individual photos to be able to zoom in for a closer look.

Here is what I brought home.

Here are the six Ptychodus teeth I found.

Here is a closer look at the lower right Ptychodus tooth in the last photo. It looks so much different than any Ptychodus tooth I’ve seen. It has the classic crown and ridges, but it’s much flatter than any Ptychodus tooth I’ve seen, and the root looks more like other shark tooth roots than Ptychodus tooth roots. After cleaning it up and looking at it closer, I’ve come to the conclusion that it just looks this way because so much of the root is broken off. The second photo below shows an end view of it, and that side view of it in my hand does the best job of showing how flat it it.

Here are the two biggest teeth of the day. That first one would have really been big if everything wasn’t broken.

Here are the other teeth I saw fit to take individual photos of.
