  1. Squalicorax Symphyseal

    From the album Post Oak Creek

    Very narrow tooth with serrations indicates it must be Squalicorax sp.
  2. Squalicorax pathology

    From the album Post Oak Creek

    Notice the dimple, not sure what caused it...
  3. 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 in case it's hard to tell from the photos.
  4. 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 listed as Squalicorax kaupi. It is collected from Lincoln Limestone member of Greenhorn Limestone formation. I suspect this tooth is misidentified and it should be Squalicorax falcatus, a paleobucket taxa for Squalicorax sp. variations. I thought Squalicorax kaupi is found from Santonian to Maastrichtian and Lincoln Limestone member is Cenomanian. I spent quite a bit looking up on here and Ocean of Kansas website comparing Squalicorax sp. tooths before posting! Although I am more confident in some of the members' identification skills than I am with mine. Regardless of identifications (or misidentifications), I am happy with both and is excited to have them arrive soon!
  5. 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).
  6. So, I came across yet another bag of teeth I had collected back in the 90's (I HATE being able to say "back in the 90s" like that) and packed away for later perusal. Now, what I did not do, which I usually do, is mark the bag as to where I collected it. *sigh* Luckily, there are only 2 places I have collected Squalicorax. Green Mill Run and Cape Fear river. I am relatively certain these are from GMR as I collected in Cape Fear later than the 90s and this was in a box packed before that. Plus they just dont look like the stuff I got in Cape Fear.
  7. Here are my new fossils! And how my collection looks now. For size comparison the enchodus tooth to the right in the picture of the entire collection is 5,6cm long (2.2 Inches long)
  8. 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 pretty good haul, 11 teeth found in 2 hours. Not bad for a nice family outing. The real highlight though were 2 shark verebrae (about the size of a bottle cap), not large, but still my first ones I've ever found which put me over the moon. They were found just a few feet away from each other, so odds are they belonged to the same critter which is even more incredible! And now it's time for everyone's favorite game, FIND THAT FOSSIL!
