    Pathology or normal?

    Hi all, I found this pristodontus tooth at Big Brook. Of all the Squalicorax teeth I've collected and seen, I haven't seen any with ridges on its lingual or labial sides. Would anyone be able to share if this is a normal feature or pathology? Thanks.
  3. I made a trip to a Navarro County creek yesterday morning. This is the same creek I visited a few weeks ago, but I was a little bit further downstream yesterday. It was still a Wolfe City formation area. It ended up being one of those days where I spent more time hiking and exploring than I should have. I was looking for likely outcrops in this creek, and just didn't find any. I eventually started checking the unlikely looking ones closely, but never did find any fossils that way. I finally spent some time crawling gravel bars, and found a few things there. I'm still a relative newbie at this,
  4. I live near the western edge of Henderson County in Texas. It's a fairly flat area with few outcrops of any kind exposed, and even when they are, they aren't very fossiliferous. The county just west of me is Navarro County, and it does actually have some formations that hold fossils. But I haven't had much luck finding anything in Navarro County. I keep looking, since it's so close. I did a long hike down a Navarro County creek yesterday. For most of the day, it looked like another of those trips where I just don't find anything. But one thing I've learned about fossil hunting is that even aft
  5. I recently went on two fossil hunting trips to Cretaceous sediments of Eastern North Carolina, the second of which was earlier today. Today’s trip to the Bladen formation yielded baculites ammonites, some worn mosasaur teeth, the nicest goblin shark teeth I’ve personally collected, some fish mouth plates, turtle shell fragments, and some other goodies. My first trip a couple weeks ago was to Tar Heel formation sediments and I collected several small mosasaur teeth, a mosasaur vertebra, a piece of petrified lignite, lots of goblin and crow shark teeth, lots of turtle shell, a very wor

    6/17/21 Trip

    From the album: Post Oak Creek

    Nothing extraordinary, but I found an area with several chunks of matrix with teeth in them.
  10. Dear Fossilforum members, I was wondering if the echinoid on this piece of matrix is indeed a Gauthieria radiata and if so, does that appoint this fossil to the lower, middle or upper Turonian? The shark tooth is a Squalicorax falcatus and the piece was found in the Ardennes departement of France. I know the age of a few locations nearby, but the age of the location where this piece is from is nowhere to be found in literature. I also am not sure if I may say where it was (it took a lot of questioning to find out where it can from haha). Therefore I hope that the echinoid perh

    Posterior Squalicorax tooth

    Hello, I have a squalicorax tooth, it is posterior. Is it rare, and if it is how much would it cost
  12. I’ve had Big Brook and Ramanessin on my shark tooth hunting list for a while and finally made it up to both today. It’s a 6-hour roundtrip drive from where I live and with the days still pretty short this time of year, I had originally planned to spend my limited time just at Big Brook. After an hour-and-a-half of mostly striking out on shark teeth there, however, I decided to head over to Ramanessin, which both @Bob-ay and @PaleoNoel had recommended. Luckily, the two spots are only about 10 minutes apart, so I didn’t waste much time in transit, and I was rewarded with much better gravels at R
  13. This last weekend I hit the NSR along with the crowds and decided to start at the Ladonia Fossil park. I got there shortly after dawn and already there were several groups of people down in the river. I don't mind walking in others footsteps and in fact quite a few of my good finds have been within feet of where others have already walked so I started off and within about an hour of slipping and sliding around on the marl I found two of the ugliest associated mosasaur verts I've yet to lay eyes on. Maybe they will clean up nicer than they look now but in my experience the preservation in the h
  14. I'm wondering what the rounded fossil might be? The place it was found contains mostly sand, and smaller shark teeths here and there. I think later createous? Really small shark teeth sometimes, not more than 2-3 mm sometimes. The rounded fossil is about 1cm on the long side. It might just be a pebble, or a fish tooth or a gastric stone, or a miss-grown shark teeth? I really don't know? I'll add some of the shark teeths for reference so you guys know the setting it was found in.
  15. Hello forum members! With the new Coronavirus raging across the world, I thought it would be nice to start some kind of advent calendar, using my own Squalicorax collection. Everyday I will post one or multiple Squalicorax teeth from one location. Let's see what ends sooner, my collection or the virus outbreak. I will start with the oldest tooth from the Albian substage and end with the teeth from the uppermost substage; the Maastrichtian. The first one is the oldest and also one of the smallest teeth in my collection. Unfortunately it is so sma
  16. I'm a newbie who lives in the Austin area with a lot of passion for ancient life, but I'm having trouble making a decisive start with with my searches. I have a particular interest in large western interior seaway predators, most notably xiphactinus, but also the mosasaurs and sharks that lived in the area as well. Finding a vertebrae, of perhaps even teeth from these groups would be absolutely wonderful, but of the few creeks in the Austin area I've scouted, I've been able to turn up nothing besides gastropods. This is still despite heavily studying the sometimes confusing Texas geological ma

    Squalicorax pathology

    From the album: Post Oak Creek

    Notice the dimple, not sure what caused it...
  19. Here are the Squalicorax sp. shark teeth I mentioned in my earlier post. As with the others, these didn't come with specific location information, but were most likely collected in the North Texas area. My IDs may be way off, so please correct me if I'm wrong. Thanks for looking! The scale in the photos is in centimeters. #1 - Squalicorax baharijensis #2 - Squalicorax pawpawensis #3 - Squalicorax falcutus #4 - Squalicorax sp. - I'm not sure what species this might be. The blade is finely serrated

    Squalicorax sp.

    Recently I purchased these two Squalicorax sp. tooths from an auction website and both are currently on the way. I have a few questions about identification since I know very little about shark tooths and also please correct any misidentifications. Seller A sold me this tooth and it was listed as Squalicorax hartwelli. It is collected from Niobrara formation in western Kansas. Is Squalicorax hartwelli considered a variation of Squalicorax falcatus? Do you agree with seller A's identification above? Seller B sold me this tooth and it was li

    8/16/20 Trip

    From the album: Post Oak Creek

    Didn't find much this time. I don't think it's rained in a while - the water looked stagnant. Also was picked over well. Favorite find is the mostly complete Cretodus (found it under a fallen tree).
