    Crow shark positions

    From the album: Post Oak Creek

    Reconstructed tooth set from a "Crow" shark - Squalicorax (could be S. falcatus) - illustrating the variety of tooth positions. Anterior teeth have erect, triangular cusps. Lateral teeth and posteriors are more common and have an increasingly posteriorly slanted crown, resembling the teeth of modern tiger sharks.

  5. 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
  6. Hello! I have a question. The Squalicorax species, kaupi and basanii: Are they the same species? For example: I got a Squalicorax from Morocco. With the label Squalicorax kaupi but I have seen the same shark teeth being named Squalicorax basanii. Is it kaupi or basanii? Here is a photo of a "Squalicorax kaupi" (not mine) but similar : Regards Adriano

    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

    COVID Containment Collecting

    After spending a great deal of time in the house lately do to COVID and days and days of rain, I took the family on a nice leisurely walk to our favorite hunting spot on this beautiful North Texas day. While the kids wwere off collecting some beautiful Turitellas and oysters, I had only one thing on the mind, shark teeth. Cretalamna seems to dominate this site, however some large Cretodus semiplicatus have been found. A Ptychodus latissimus and 2 Plesiosaur teeth have also been found at the site, filling us with hope on each trip for an incredible find. The trip was a p
  9. Hello, I'm looking at this shark tooth for sale, which is listed as Squalicorax bassani from the Phosphate beds of Morocco (scale in cm). I quite trust the seller and as far as I can tell it looks to be the correct species based on a cursory search. However since I am a complete rookie to teeth and have never bought any before, I wanted to ask for a confirmation on the species, and ask how is the quality? Is it good/medium/bad? The other S. bassani teeth I see don't usually have this reddish brown coloration, rather they are ivory/black and shiny, com

    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.
  12. 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,
  13. 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
  14. 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.
  19. 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
