Newbie Notes I’ve had these fossils for a while. I’ve had a chance to research them and I have an idea of what they might be . . . but as a newbie I’m not positive. So, I defer to the professionals for the final ID. With the help of the veterans at this forum, (11) fossils were ID in my first two posts. Thanks. The following pics are group number four. The first fossil in this group was found a great distance away, but the depositional environment appears to be the same or similar.

The last fossil in the group you’ll notice the depositional environment is different. It was found where the creek flows into the river. I sat down to eat lunch and there was the fossil.

Newbie Notes Updated and revised from 6/28 ~ September 2020 I decided to become a fossil hunter. I searched the internet and found the North Sulfur River. My first three visits I found coral fragments and small fossil wood. I was still hopeful. I then reviewed several maps of the area and decided on the road less traveled by. Went there November 2020 and found my first fossil. I followed the strata in which that fossil was found. The strata led me up a creek and that creek was laden with fossils. I hunted that creek countless times and found a bunch of nice fossils. On my last two visits they were scarce, so I stayed away for six months. I returned this May and it was the same as it ever was. I’ve had these fossils for a while. I’ve had a chance to research them and I have an idea of what they might be . . . but as a newbie I’m not positive. In the first group I posted for ID, I thought a cervical vert was a pygal/postpygal and a scapula was a coracoid. So, and as it should be, I defer to the professionals for the final ID. With the help of the veterans at this forum, (7) fossils were ID in my first post; they made it look easy. Thanks The following pics are set number two. I thought the fossil dated 1/18 was a piece of wood until I turned it over. The second and third on 2/7 came in quick succession. Three months later I found the fourth fossil in this set. I did review Russells's Manual and found the last fossil on page 50 . . . I've got more here related to these, just got to process the pics.

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 site. I hope to read it once it's published! Anyways, the day was miserably hot as expected, but the scenery and air of discovery made up for it. My brother and I took a more secluded route, traveling downstream whereas most headed upstream. After a bit of searching, I came across a part of the creek bed that was red and, upon close inspection, was filled with tiny black phosphatic fossils. Because the matrix of the layer is so sticky, we couldn't really sift through it at the site. Instead, we, like everyone else, filled up a bucket and took it back to our car. It was a fun day and I met a lot of interesting people. One member told me to use baking soda to break up the matrix and that advice worked like a charm! I'm not sure about a lot of these IDs so feel free to correct me. If you know any species names feel free to drop those too . Here are the pictures of the highlight finds. Sorry the quality is bad... taking pictures of things this small was more difficult than expected: Fishes Lots of Enchodus Fangs and Jaw Sections Lots of Hadrodus Teeth Pachyrhizodus? Teeth Protosphyraena? Teeth. Really not 100% on this ID Pycnodont Teeth Fish Neural Spine. 2nd photo is compared to an X-Fish neural spine I found in Austin. Love the size discrepancy of the two. Fish Verts (Left) and Shark Vert (Right) Sharks Hybodont Shark Tooth. This is one of my favorites. Looks like Lonchidion? but that's just my guess. Lots of Pseudocorax Teeth Lots of un-ID Shark Teeth. Distinguishing between Scapanorhynchus, Carcharias, etc. is way above my pay grade . Trust me, I tried... Cretalamna appendiculata Tooth. By far the biggest tooth. Protolamna? Teeth Squalicorax Teeth. For some reason they all came out broken. Unidentified Tooth. Pathological? The crown is just a flat edge. Shark Coprolite? It's ringed like the ones I've seen online. Sawfish Ischyrhiza Oral Teeth Ischyrhiza? Rostral Teeth Ptychotrygon? Oral Teeth Cantioscyllium? Oral Teeth Misc./Enigmatic Finds Brittle Star Parts? Part of an Urchin? It's rounded and the center has a protrusion for where a spine once was. Kinda looks like a denticle, but may be some weird tooth? Bivalves If you would like any additional pics, let me know. Thanks for reading!

Newbie Notes Long story short. September 2020 I decided to become a fossil hunter. I searched the internet and found the North Sulfur River. My first three visits I found coral fragments and small fossil wood. I was still hopeful. I then reviewed several maps of the area and decided on the road less traveled by. Went there November 2020 and found my first fossil. I followed the strata in which that fossil was found. The strata led me up a creek and that creek was laden with fossils. I hunted that creek countless times and found a bunch of nice fossils. On my last two visits they were scarce, so I stayed away for six months. I returned this May and it was the same as it ever was. I searched the internet and I have an idea of what these fossils might be . . . but as a newbie I’m not so sure, so I need help to ID. The following first set of pics include the first fossil and one of the latest. Thanks in advance for your time to ID. I hope you find these fossils as interesting and fascinating as I have. ~

From the album: Squamates
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 a different spot on the North Sulfur River this morning. I had been to this spot one time last year, but an unforecast rain shower showed up and turned the river into such a muddy mess that I turned around and left without finding anything. With a 100 degree high forecast for today, I didn't figure rain would be a problem. I found some of the usual things you expect to find at NSR, Hamulus worm tubes, a gastropod, a perfectly preserved complete bivalve, some interesting bones, and lots of bacculites. The only bacculite I brought home was the one in this photo, with the great suture lines.
