  6. 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?
  7. 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.
  8. 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
  9. @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.
  10. 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.
  11. 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.

    A Xiphactinus vertebrae from the North Sulphur River.
  13. Texas Cretaceous Fish

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

  15. Xiphactinus Vet

  16. Xiphactinus Vert

  17. It was my first time hunting in awhile due to my crazy work schedule. Since we haven't had a good rain I figured it would be picked over. I found some really nice Mosasaur verts, coprolite and my best Clidastes jaw section yet with multiple replacement teeth showing. The fish vert is from one of the large Cretaceous fish probably Xiphactinus. The artifacts, Gastropods, Enchodus tooth, Mastodon tooth enamel and other Pleistocene tooth were a nice bonus. You can see little bones in all the coprolite. I will hit it again next week for sure.
  18. Xiphactinus Or Enchodus Id help - GMR NC

    Could someone assist in determining if these two items are an Enchodus or Xiphactinus? I found the larger one this past Saturday and the smaller one a few weeks ago, same general area at GreensMill Run in Greenville NC. Found these among whale bone, great white, tiger and crow shark teeth and a couple sharks of likely mastadon tooth - obviously a nice mix from a huge time span. I assumed enchodus until a friend mentioned the Xiphactinus, which I didn't even know was an option yet, so I would also appreciate detail on how I can discern between the two in the future - characteristics etc. 1. 2. and I also have several of these, ranging in size/condition some with enamel etc - this one as I'm taking photos I realized the tooth part of it might not actually be what I was thinking for this one, but the rest have the more rounded tooth, anyhow, are these jaw pieces with broken teeth like those above to be identified?
  19. NSR Last Saturday

    Haven't posted a trip here in a while, but have had some good ones. These are some of the finds from Saturday. My son and I combined for some nice pieces.
  20. 3-9-17 Great NSR Trip

    I took a long 8 - 10 mile hike at NSR. The weather was beautiful and wildlife abundant. I saw hogs, deer, beaver, hawks, ducks and geese among others. I picked up a nice variety of fossils. I really like the Xiphactinus jaw with replacement tooth showing. I sat down to take a break and found 4 shark teeth in one area. The little fossilized turtle scute is also cool.
  21. Xiphactinus Jaw

  22. I'm assuming all are enchodus except the bottom left 2, I'm assuming sawfish if u guys could confirm....thanks!
  23. Killer NSR Texas Hunt

    8 mile NSR hike trying to get past all the footprints. I had a great day. I found a nice variety of Pleistocene and Cretaceous fossils and all kinds of artifacts. I really like the partial Mosasaur / Pleisosaur scapula with shark feeding marks. The Mastodon tooth enamel has some great color. The Ammonite septum that size is pretty rare for NSR. 2 Mosasaur teeth in one day always makes my day.
