  1. In the last three and a half months I'd say I finally had the true college experience - always tired, hungry, and getting strangled by ochem 2 . But, my last final was yesterday, so time for a long overdue trip report. I'll go consecutively, with brief notes on the sights and interests encountered along the way, culminating with a prep update on the Plesiosaur I found over the summer with @Ptychodus04 and Joe. Unfortunately, the block containing the Coniasaur from the same trip hasn't been scanned yet. I'm also twiddling my thumbs for updates August/September:
  2. I’m planning my return trip to Lake Texoma and I was wondering if y’all had any suggestions for tools to bring. Preferably batter-powered (no generator) and powerful enough to excavate large ammonites from hard limestone. Explosives, battery acid, and hydrochloric acid are out of the question. I’d settle for gas-powered tools, but only as a last resort.
  3. My son found this last week while poking around Post Oak Creek in Sherman Tx. The bumps and ridges on the sides are symmetrical, and it has a smooth hollowed out portion. Not sure if it’s part of a fossil or just an odd rock formation. Hoping someone here can help us out. Thanks!!

    Duck Creek Formation Shark Tooth

    Over the weekend I found this tiny (~3mm) shark tooth on a loose rock at a site exposing the Duck Creek Formation (and maybe the overlying Fort Worth Limestone). I have tried to match it with the teeth in The Collector's Guide to Fossil Sharks and Rays From the Cretaceous of Texas but the closest I have been able to get is Squalicorax sp. and even that doesn't seem to quite match and the book states that Squalicorax in the Texas Albian have only been found in the Weno and Pawpaw Formations. Unfortunately it only seems like the blade of the tooth is preserved as there is a bit of a lip where th

    Texas Nautiloid With A Surprise

    A few weeks ago my brother and I took a weekend trip to do some sightseeing in the Dallas-Fort Worth area. I had been meaning to check out an area of interest in the Late Cretaceous Period, Early Cenomanian Grayson Marl, so early Sunday morning before the museums in Dallas opened I made a quick stop to the site to at least cross it off my list. The outcrop itself was small but I was able to find the usual suspects- Ilymatogyra oysters and Neithea scallops, partial Mariella bosquensis heteromorph ammonites, and a Stoliczkaia conlini ammonite that is sadly missing its juvenile whorls. The real h

    NSR Red Zone Ammonites ID Help

    A couple of weeks ago I made my first ever trip to the North Sulphur River "red zone." I had a blast collecting some of the ammonites there- and I thought I did pretty well- but boy is hiking through the river a lot of work. I was really happy to be able to find a nice variety of ammonites, including these two ammonites that I cannot quite seem to fit within the ammonite faunal lists I have seen for the Ozan Formation. I also found this tiny phosphate chunk in a concretion of the "red zone." I would normally say that it is a random chunk of phosphate, but I thought that the banding was unusual

    4 Mosasaur Verts in a Day! Austin TX

    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

    Whiskey Bridge Gastropod ID Help

    Many months ago I visited the famed Whiskey Bridge locality. Perhaps due to laziness or a desire to collect other fossils in Texas I have only now gotten around to cleaning, consolidating, and identifying my finds. Using the Emerson book I have largely been successful in identifying my finds. However, I have been stumped on the last dozen or so gastropods. Most of them are tiny, and likely juveniles, which has made identification even tougher. I was wondering if anyone recognized these gastropods. They are Middle Eocene in age, from the Stone City. Any help would be greatly appreciated. Thank

    A Physicist's Collection

    While my prime focus is essentially learning how to accurately describe Nature in the precise language of mathematics, I've always been intrigued by natural history - it's actually what started me on the path to physics. The sort of interrogation that paleontology practices provoked me to think and question even further, down to the fundamental science which makes it all work. Collecting fossils has brought a large amount of enjoyment to my life, and is often a welcome distraction from what can sometimes be straining work. The knowledge that I accumulate along the way is also part

    Waco Pit ID Help

    Although the primary draw of the Waco Research Pit (Cretaceous; Del Rio Formation) is its tiny micromorph ammonites, I have also found a number of other fauna at the site, including these bivalves. These are the last fossils from the Waco Pit that I have not yet been able to identify. I was hoping that someone with more familiarity with the site or bivalves of the Texas Cretaceous might know what they are. Any help would be greatly appreciated. Thank you so much! #1- ??? #2- Striarca washitensis? #3- ??? #4- ???

    Texas Pennsylvanian Brachiopods ID Help

    Over a couple of trips to several exposures of the Late Pennsylvanian Colony Creek Shale, I have collected a few larger brachiopods that I am not completely sure of an identification for. I was hoping that someone might know what these are. Any help would be greatly appreciated. Thank you so much! #1- ??? #2- ??? #3- Antiquatonia portlockiana? #4- Kutorginella lasallensis?

    Wilson’s Clay Pit Unknown

    I found this over the weekend at Wilson’s Clay Pit (Harpersville Fm, Pennsylvanian). I know that there are a number of strange looking rocks there that look like something but are really nothing. I ended up picking it up and keeping it because it was unique and I thought that it could maybe be something. Does anyone know what this could be? Is it just one of those rocks that look like something but is really nothing?
  13. A projection of rain in the forecast for Saturday caused me to change my plans at the last minute and venture a little further west than I had initially planned and hoped to go. Since I had not yet visited Whiskey Bridge since moving to Texas at the beginning of September I decided that it posed as a nice alternative, especially when trying to decide on Friday night where to go the following morning. Plus this way I could also collect some petrified wood in College Station. This petrified wood is from the Late Middle Eocene Yegua Formation and is absolutely abundant in the Bryan-College Statio

    Fresh Ammonite Fossil

    We actually found this about 1.5 years ago, just before moving to Florida. (Moved here a year ago). My son got it while he was at my parent's house in the outskirts of east DFW (we lived in north DFW, they lived in east DFW - we both relocated to FL). Their area was well known for dinosaur bones and the likes, which is super crazy lol!! Common to dig them up in yards while doing fences and whatnot. Anyway - my stepdad took my son to the cul-de-sac (2 houses down), one day where they were starting to build more houses. Kiddo wanted to check out the dirt & rock piles... He ended findi

    First Texas Cretaceous Hunt

    Well it is not my first ever hunt in the Texas Cretaceous, but it is at least my first hunt since moving to Texas at the start of this month. This past Sunday I had the chance to journey to several sites that expose the Early Cretaceous Glen Rose Formation. Through some research on known sites and scanning Google Maps for other potential localities worth checking out, I came up with a list of about more than a dozen nooks and crannies in Central Texas worth exploring. Virtually every place I stopped showed potential, although I did not find echinoids at every site, but that also meant that I c

    Pointy Spiral Shell

    Helotes, Tx Part of this shell was sticking out of a chunk of sediment. I used a water pick to clear the rest of it. In trying to determine what kind of shell it is, I’ve found several that are similar, but none with the shell spiral as tight. The closest thing that I could find is below. This doesn’t seem correct considering my location. Placostylus porphyrostomus is a species of large air-breathing land snail, a pulmonate gastropod mollusk in the family Bothriembryontidae. This species is endemic to New Caledonia.

    Rock or Fossil?

    I found this rock on the edge of the hill in my backyard in Helotes, Tx. The previous heavy rains have exposed a lot on my hillside. I am in sure what the wood looking pieces are in pictures 3&4. If anyone is familiar, that would be great.

  21. I found this partial nautiloid at Jacksboro. Finis Shale member, Graham Formation, Pennsylvanian. The odd part is how deep the umbilicus is. There was just enough of it to see a piece of intact inner whorl for the profile and some septa to know about how much bigger it could have been if an adult. There was also a piece of the flank broken back with tubercles. I made the clay model of what it might have looked like whole but left off most of the tubercles. I will add photos comparing it to a Metacoceras fragment of about the same diameter that shows the depth from the flank to the previous who
