  1. Hello! These were all found in Monmouth County, New Jersey (Late Cretaceous). I have believed the first tooth to be Xiphactinus Vetus for years but am a little thrown off by the general texture of it and after searching images of Xiphactinus teeth, I can't find another that looks similar. I have found deteriorated Mosasaur teeth with a similar appearance so I was wondering if it could just be stream-worn. The tooth is about an 1.5 inches long, has two very defined cutting edges and a nice curve (which are all consistent with X. Vetus). The last thing I could add - it either has 'fluting' or is faceted but I'm not sure how to determine that. The second set of pictures is of different shark teeth from the same location. As always, all help is greatly appreciated! -Frank
  2. Western Interior Sea way finds

    Ive been hunting the Sulfur River for 10 years and here is a small handful of the Sulfur River finds of mine including the partial Toxochelid I found sticking out of the shale and the 35 pieces of shell and a couple pieces of bone I recovered.
  3. NJ Cretaceous & Mammal Teeth

    Hello everyone, this is Trevor. I have been meaning to post this for a long time and finally got around to doing it. I would appreciate help identifying these finds. Also, stay tuned I have a trip report coming out later this week, probably Friday. What type of ammonite is this? (middle)
  4. Partial Xiphactinus Jaw

  5. Unknown Cretaceous tooth

    I found this tooth last week in the blufftown formation that runs through South Alabama. It was found on the same bar as the fully rooted Xiphactinus tooth I posted a couple of weeks ago. To me, it appears to be another tooth with a partial root but I’m unsure. It has characteristics of both Xiphactinus audax and vetus so that’s what has me so puzzled. It’s just over 1.25 inches long and a .25 inches wide. Any thoughts/comments would be greatly appreciated!

  7. Xiphactinus jaws advice

    I need some advice here. It's been a dream of mine to have a xiphactinus jaw, and here I have two. They are both dentaries: right and left side. (Let me say I will not be purchasing these for probably a good few years.) I wanted to know if it's possible to separate them and remount them to make an inflated lower jaw? I would probably have to send them out to have a professional do it because I have a feeling this is a job for the masters.
  8. Unknown Cretaceous tooth

    I’m pretty sure this is an xiphactinus tooth but I’ve never seen one that’s fully rooted before so that’s what has me questioning my original thought. I have several X-fish in my collection but all appear to sheds or broken off where the root would’ve been. I found this tooth last Sunday on a bar where I’ve found 10-12 other X-fish. It was found in the Blufftown formation of Alabama and is 1-5/8” long, 5-16” wide. Any thoughts or comments would be greatly appreciated!

  10. I haven't had much time to hunt lately but I did manage to squeeze in a North Sulphur River creek hunt. My finds were not great but I did manage to find a nice variety. The fossil horse cannon bone is probably my favorite due to the preservation. It's solid rock. Lol my grandson carried it around the house all night when I brought it home. The Xiphactinus vert, old bottles and artifacts were a nice bonus to the usual Mosasaur material. This creek has some killer flint in it so I can see a nice arrowhead coming soon.

  16. Is this a good idea?

    Hi all. First off it's a dream of mine to one day have a skull from a xiphactinus audax. I have here a xiphactinus skull, but as you can see it is heavily disarticulated. Would it be a bad or good idea to try and have this skull professionally restored?
  17. Weird question i know, but i found this large coprolite from a Cretaceous inland sea site near Richmond in QLD, Australia and it is by far the largest single coprolite i have collected. As you can see it is almost the size of my hand, though if whole it would have actually been even bigger as there is a clear break on one edge where it would have continued further. The sea at this time was inhabited by a range of marine reptiles (7m ichthyosaurs, 10m long necked elasmosaurs and 10m short necked pliosaurs) but also by some pretty big fish, the largest of which was the ichthyodectid Cooyoo australis (a relative of the more famous Xiphactinus audux). This species could grow to about 2.5 - 3m long. There isn't really a sure way of knowing what produced this coprolite, but i was hoping maybe i could rule out fish simply based on the large size. Assuming a maximum sized Cooyoo, would a 3 metre fish be able to produce a poo of this size? Or can i safely assume it belongs to one of the larger marine reptiles? This is probably a question best aimed at collectors of the Smoky Hill Chalk as they may be familiar with the size of large fish coprolites such as those of Xiphactinus. @KansasFossilHunter @Xiphactinus Interestingly there is a small belemnite poking out of the coprolite on one side, so whatever it came from must have been eating belemnites. I'm thinking ichthyosaur is most likely.
  18. three vertebrae in question

    Good evening, I have acquired these three vertebrae from a creek in Travis county where I regularly find shark teeth and echinoids. I have my suspicions on what they might be but would like a definite ID, thanks. Disregard the background ha
  19. @KimTexan asked to see some of my jaw sections so here's a few from the North Sulphur River Texas. This is a nice mix of Xiphactinus and at least 2 species of Mosasaur.
  20. Smoky Hill Chalk, Kansas ID Help

    Today I came across a flat of Cretaceous Niobrara Formation / Smoky Hill Chalk- Kansas fish fossils, from a couple years ago. I was hoping that @Xiphactinus or other members might be able to help with and / or correct son ID's that I made on the following specimens. Any help would be appreciated. Xiphactinus audax Vert. Enchodus Tooth Saurodon leanus Jaw Sections Cimolichthys Jaw Sections Unknown Jaw Section Unknown Tail / Fin Pieces Unknown Fish Vert.
  21. Hot NSR Trip!

    Hot long NSR trip. My legs are sore lol. Nice variety today including attached verts, bison tooth, mosasaur verts, multiple fish jaw sections, turtle shell, gastropods etc.

    Found this fish tail yesterday, and was wondering if there is enough here for an ID? Thanks
