  14. Over the month of December, I've gotten the opportunity to check out several sites across the state of Texas. In my fossil interests, I have to admit that I am certainly a bit vertebrate-centric, but that does not mean I will pass up the chance to marvel at a beautiful invertebrate specimen when given the chance. For better or worse, these past four mini hunts have not really delivered on the vertebrate end, but have made up the difference in terms of inverts. I've decided to combine these smaller hunts into one report. For those with invertebrate addictions, I hope this sampler of Texas fossils will meet your medically-necessitated daily dose of invertebrate content. Enjoy! Maastrichtian No Mas Kemp Clay and Corsicana Formation Leading up to my eventual move away from Austin back to DFW, I made sure to visit a nearby site that possessed some Maastrichtian exposures. Back up in Dallas, the nearest exposures of similar age are a bit of a drive, so I wanted to take the opportunity to travel to a convenient spot while I still had a chance. I had previously seen this spot mentioned in some old literature, where it was described as exposing the Kemp Clay at the top of a bluff and Corsicana below. Since I had no prior experience with these formations, I wasn't sure what to expect or what to look for in terms of identifying formations. One Saturday afternoon, I carved out a few hours to take the drive and a brief hike out to the spot. I was excited to finally hunt a stage of the Cretaceous I had never searched before. The landscape was quite dramatic and I could see out for miles. Pictures really do not do the place justice. The drop from the trail to the creek bed is much higher than the picture makes it out to be. After navigating my way down, I was immediately confused by the formation the creek bed was composed of. Perhaps I am just too Ozan-minded, but the shale looked almost indistinguishable from my usual Ozan hunting spots elsewhere in the area. It had that classic bluish grey color and was even filled with rather large Exogyra oysters. I began to wonder if so much time and weathering had passed that the creek had finally reached down to the Ozan far below. However, a closer inspection showed that there were some subtle key differences. The wavy shells of the oysters were not indicative of the species E. ponderosa, but instead of E. costata, which is present in the Corsicana Formation at least according to the paper I had read about the site prior. There was also a pronounced presence of tiny phosphatic bivalves that I had never seen in the Ozan. With this information, I was relieved to know that my goal of collecting in the Maastrichtian could continue without issue. Some leftovers from an earlier fossil hunter. Not all of these are E. costata since they washed down from older strata upstream. With little direction as to where to look first, I decided to plop down and try splitting open some chunks of mudstone that had fallen down from a grey and brown formation at the top of the cliff (Kemp Clay I'm assuming). Initially, I didn't find much, but eventually some invertebrate fossils began showing up. I was intrigued by the presence of the original shell on a few gastropods (I hadn't been to the Whiskey Bridge at this point so this was a first for me). They were ornamented, unlike the steinkerns I had been accustomed to for the entirety of my Cretaceous fossilizing career before. Unfortunately, none of them were preserved well and were more so just crushed messes too fragile to take back. In the same rocks, I came across various bivalves that were fairly nice to look at and ended up keeping an orange 2D one, though I am having a difficult time identifying it. A gastropod with the original shell from the Kemp Clay(?) A flattened bivalve(?) from the Kemp Clay(?). It's about 30 mm across, orange, and has thin red lines between the ribbing. At first, I wondered if it was a smushed trigonia, but I'm doubting that now. Afterwards, I surface collected along the bed and climbed some of the cliff where Corsicana was exposed. There wasn't much in the way of large finds, but getting close to the ground revealed a plethora of smaller finds to be had. The first objects of interest were highly detailed button corals. The closest thing I could find online as an ID was the genus Micrabacia which is known from the Peedee formation (also Maastrichtian). I came across a couple bits of crab claws as well. My vertebrate hopes for ginglymostoma were never fulfilled, sadly. Instead, I found only three sharks teeth that were all missing roots . I don't think they can be identified, but I welcome you all to toss out ideas if you have any. An in situ of what could be a Micrabacia button coral. As I walked along the cliffs, I couldn't help but think about the time period I was traversing through. In the formations beneath me were the Cretaceous layers I had grown so used to. In those days, mosasaurs and dinosaurs dominated the world. It's mind boggling to realize that the strata just above the Kemp Clay was the geological blink of an eye that saw an end to all of it. All those billions of ammonites and not a single one made it through such a barrier. Even something so simple yet prolific like exogyra was put to a complete stop. The Maastrichtian was not a final stand by any means either. That day 66 million years ago may have started just like any other, but ended with the world being permanently changed in a way that is almost unimaginable. Speaking of days ending, the time was 30 minutes till sunset. With the day winding down, I decided to circle back and try splitting some more mudstones from the Kemp Clay in hopes of finding a shark tooth before calling it quits. Rock after rock, I couldn't seem to find anything other than the usual tiny clams and crushed snails. As the light started to dim, I was finally greeted by the sheen of shiny black enamel. It had a strange shape to it, but this being a new place for me, it could have just been a weird shark for all I knew. As I chipped away at the rock, more and more of the specimens figure was revealed. Finally, I realized that all of my labor had been put into exposing a simple enchodus fang, no different from the hundreds I had seen before! And yet, I was still happy with it. After the disappointment of the broken shark teeth from before, it was nice to at last have a complete tooth from the Maastrichtian, no matter how common the animal may be. With that, another stage of the Cretaceous was crossed off the list. Some pics of all of the finds: Strange bivalve, a gastropod, Micrabacia(?) corals, and perhaps a scaphopod? Top row L to R: Crustacean claw bits, and the enchodus (petrosus?) fang. Bottom L to R: Worm tube, and three rootless shark teeth Eocene Escargot Stone City Formation Fast forward about a week, and the time had come for me to pack my things and leave my dorm once and for all. I usually drive straight to Dallas from Austin, but this year things were different. My carless brother started his first semester at A&M, so I volunteered to pick him up on the way home for the break. Being the person that I am, I simply cannot drive all the way out there and NOT visit the world-class site known as the Whiskey Bridge. I made sure to turn in my dorm key early in the morning and head on out for a quick hunt in the Stone City Formation along the Brazos. I was hoping @Jared C could join in the fun, but he unfortunately had a final that same morning . I'm pretty sure passing the class wasn't that important, but I won't hold it against ya . Before making the drive, I had also done a bit of research into which layers yielded the most vertebrate material. Even with the information, however, I still had measured expectations as the Stone City Formation is of course much more famous for its rich invertebrate fauna. The goal for the day was to find some vertebrate material and perhaps a complete cone snail. When I arrived, the place was still covered in mud from the storm a couple days before. With hopes that the popular site had been replenished, I carefully made my way down to the water, passing by a couple of hunters just finishing up their session. The plan was originally to head straight for a productive spot a ways from the bridge, but of course the newness of the place and its fauna had me stopping in my tracks every few steps to pick up a gastropod. When I finally got to the spot, I slowly climbed up the slope to meet the fine hash layers atop the ledge. There is never a dull moment at this locality. Every square inch of surface is covered with bits of white shell. The first oddball that caught my eye was a strange looking piece of coral. Madracis johnsoni Side stepping to the right while hugging the wall of soil led me to my next noteworthy find and the first of the vertebrates! The skinny crown and wrinkling of the enamel was a familiar sight for someone who has collected so many scapanorhynchus teeth in the past. However, it would seem that, for this formation, a sand tiger shark was the more likely ID. I'm guessing this is from Striatolamia macrota. The weathering on it is likely due to prehistoric reworking I would assume. Striatolamia macrota? Not so long after, I sidestepped my way into finding my first ray plate! Unfortunately this one was also in not-so-perfect condition. Myliobatis sp. fragment I couldn't stick around for too long since my brother was waiting for his pickup. I rounded off the trip by filling up a couple bags with fine shell hash matrix for future screening for microfossils. I didn't take too much though, as I have a secret side project involving many bags of micromatrix that is currently occupying most of my micro attention. If I find anything special from the hash, I will be sure to add an update to this topic. Overall, it was a solid first visit to a famous site. I managed to find some vertebrate bits and bobs that I'm happy with. I am a little bummed I never got a complete cone snail, but I guess that will just have to wait for a future outing. Overview of the finds: Top: Dentalium scaphopods Bottom L to R: Striatolamia macrota tooth, Myliobatis ray tooth fragment, reworked Carcharhinus mancinae? tooth, and Conus sauridens fragments Top L to R: Lunulites bouei and Schizorthosecos sp. bryozoans, and Turbinolia pharetra coral. Bottom L to R: Fish otoliths (not sure how/don't want to ID), Balanophyllia desmophyllum, and Madracis johnsoni Top L to R: Weathered Architectonica elaborata?, and probably Venericardia densata that looks strange since it doesn't seem to curve like others. Mid L to R: Anomia ephippioides, Vokesula smithvillensis, Notocorbula texana, and perhaps a worm tube? Bottom L to R: Large Anomia ephippiodes, and a trio of Venericardia densata Top L to R: Athleta petrosus, Ancilla staminea, and Pseudoliva vestusa Bottom L to R: Athleta lisbonensis, Architectonica scrobiculata, and Sinum arctatum Top: Michela trabeatoides Bottom L to R: Protosurcula gabbii, Hesperiturris nodocarinatus, Cochlespira engonata, and Protosurcula gabii though they look different from the one on the left of the row. Top L to R: Distorsio septemdentata, and Latirus moorei Bottom L to R: Mesalia clairbornensis, Turritella nasuta, and Gegania anitquata Phew that was a lot to identify. I'm sure I got plenty wrong, so feel free to correct me on any of these. I will probably find a ton of new species in the micro matrix that I can add in a later update!

    Not in my books...

    I was at a sand bag station pile and found some goodies .... I think the rounded top cones on the bottom are Conus Carlottae- they show a very particular pattern under UV light and this is the 2nd time now finding these shells at this location. Wish I knew where the dirt came from....! Then we have this volute looking thing that I haven't seen before either ... anyone know what that is? On the left is what we would call a zigzag flat today...a deep water scallop that's top is flat and bottom is more deeply curved than a Calico. You can see the casting of the inside of the bottom shell and the top mineralized in there it's pretty neat For reference, we have an old Alphabet cone moon snail and murex and some olives, all from the same pile ... along with a heavier clam that is a bigger version of today's Beautiful Crassatella. Those 3 in the second row from the top are ones I am having trouble finding. The leftie cone on the bottom is a Conus Adversarius with a busted tip....
  20. Hello, here are some pics of my finds from Whiskey Bridge that I did earlier this year. I really enjoy this site as to the variety of fossils to be found and the nice preservation of them. First one is: Rotularia lepstostoma (worm tube) I thought it was a funky gastropod until I looked it up.
