So a couple of weeks ago, I, along with my younger brother, decided to embark on our first field trip with the Dallas Paleontological Society. The destination was Moss Creek, a decently sized waterway on private property that feeds into the NSR. Just like in the main river, we were seeking a red layer exposure of the Ozan Fm (though I read that this red layer is different from the one at the river). This site is famous for its abundance of marine microfossils, namely shark/fish teeth. One of the people on the trip was a researcher (Shawn Hamm) who is currently finishing up a paper on this very

A tooth from a large mosasaur that inhabited the Western Interior Seaway during the Late Cretaceous. Tylosaurus was an apex predator with thick teeth that allowed it to predate on anything in its ecosystem from large turtles to sharks. This particular tooth has clear feeding wear on the tip.- 2 comments

I made a trip to the North Sulfur River June 21st. Among the things I found were these three bones, which I can't identify. Bones from this part of NSR are from the Ozan formation, and are usually mosasaur or fish. Here are three views of bone #1.

I finally took a trip to the North Sulphur river last week. There have been a couple good rains so I was hoping that would uncover some stuff. The last couple of trips in 2021 were terrible. All muddy and picked over. This trip was still pretty muddy and little in terms of quality mosasaur material. However I went low and found a lot of smaller material. I wonder if the recent muddyness of the river is due to the lake construction or if the river just hasn't had enough rain lately? Is picture 2 an enchodus jaw? I believe the pictures of item 3 are of a really chipped pi

Hey everyone! This came from the same Ozan spot as my previous post. I found this little specimen on a gravel bar. I think it's a fossil, but it could be man-made... I'm really not sure. My best guess is a pycnodont tooth plate which would be a first for me. I have hesitations because the teeth are "holey" as opposed to little black bulbs. Maybe this is from weathering? Here are some pictures: Thanks for reading!

Hey everyone! I thought I'd share a few of my finds from the past couple months and get yall's opinions. Over winter break, I went back home to North Texas and did some searching around Ammonite Beach at Texoma and the NSR with my family. At Texoma I had a nice time hammering out a few ammonites, collecting teeth, and surprisingly finding lots of smaller, pyritized ammonites that I did not expect to be there. The NSR was a bit slower, but I at least got a nice Squalicorax as shown in the pics below. Since school has started, I've been down in Austin. I've been finding the usual stuff, but the

Following the brief rains from earlier in the week, I decided to make a return to my new favorite Ozan outcrop where I had previously found so many mosasaur vertebrae. Though I did not get to add any new verts to my collection, I did manage to come across plenty of unique fossils and artifacts that have taken up my attention for the past couple of days. One interesting thing I have noticed from this outcrop is its abundance of pyritic bony material among other pyritic fossils (including "rusty" exogyra shells + bivalves). Most of them are unidentifiable chunks, but a few have enough distinctiv

With the end of the semester approaching, school has picked up and I have been too busy to embark on many adventures. When my schedule finally cleared up one afternoon following a brief rain in Austin, I jumped at the opportunity to do a bit of exploring. One of my goals right now is to check out new parts of the creek I hunt on. Scanning through my list of potential spots, I decided to try and be the first one out to a very promising location. Like my previous hunts, this place ran through the Ozan formation, so my expectations were set on some nice Cretaceous specimens as well as the usual n

I have two teeth of what I think is the same species, and I just can't decide what they belong to. The best speciman is this one: It's found in a creek that exposes both the Ozan and possibly the underlying Dessau formation. I see no nutrient groove, making me eliminate Scapanorynchus Seemingly no enamel wrinkling, making me not think Cretodus (can Cretodus even be found in Ozan aged rocks? I've only really seen it being found in Eagle Ford...) I don't remember Cretoxyrhina mantelli having cusps anywhere in its dentistry Doesn't
