    Mosasaur Vertebra?

    Hey all This isn't mine but I've had someone ask me if I'm able to shed some light on this, it's been in her collection for some time and she wants to know if what she got is what she paid for.... it's beyond my knowledge base but I know for some of you, this is your wheelhouse! Mosasaur vertebra is what she was told it is. Scale is CM
  2. Fossils of 30-foot prehistoric marine lizard unearthed by Perot paleontologists. Called mosasaurs, the lizards were ‘great white sharks’ of the dinosaur era (From left) Mariah Slovacek, the Paleo Lab collections manager at the Perot Museum of Nature and Science, Ron Tykoski, the Perot Museum’s director of paleontology and curator of vertebrate paleontology, and Dori Contreras, a curator of paleobotany at the Perot Museum, excavates part of a mosasaur’s skull, lower jawbones and several vertebrae from its spine found in a creek bed on Friday, July 15, 2022, near the North Sulphur Rive
  3. Goal: collect all Pierre Shale formation main fossil specimens. During my fossil hunting trips I collect a lot of different fossils but never take the time to figure out what it is exactly. Here I will record my trips and finds but more importantly try to identify what it is. This list will encourage me to not just look for the big marine reptiles but also smaller things I normally ignore. I understand how unrealistic this goal is but it's fun. Any feedback or suggestions are welcomed! Specimens shown on wiki for Pierre shale. Marine vertebrates
  4. I think is marine reptile. Poorly fossilized. Also how to post many pics at once?

    Mosasaur skull piece? Pierre shale sd

    This fossil has many grooves, holes and structures. My only guess is it's a part of a skull of mosasaur or plesiosaur. Any ideas? Or good reference pics of skull parts for comparison? Thanks

    Moroccan Mystery Vertebrae

    I was looking through the auction site for the 100th time this week, and saw what are supposed to be Mosasaur vertebrae. Apart from size, they don't look like any Mosasaur verts I've seen. These look more like very large Enchodus verts to me. The slab is 19"x7". I'm not buying them at the moment. I'm just curious as to how correct I am.
  7. Found this is ramanessin brook nj. I've been going since I was a kid and have never found anything like this. Any help IDing is very much apreciated.
  8. 2ft long block. found weathered and near other marine reptile and fish fossils. Couldn't find any more parts to this. Is this a tail? Seems small compare to other mosasaur verts I find.

    Dried up North Sulfur River

    Last week I visited NSR first time since last year. It was brutually hot with 110 degrees on the river bed. There were no flowing water at all and most vegetation were turning brown. Also no signs of animals due to a drought. I managed to find piece of mosasaur vert though. Not worth visiting again until late fall or when it rains again.
  10. I was in my local rock shop today just killing some time before an appointment and I found this tooth in with his morroccan mosasaur teeth. It’s got really fine serrations on the edges so at first I thought shark but that doesn’t seem right either. The folds? Waves? In the tooth is throwing me. Any suggestions? Thank you for looking!

    Any repair or restoration?

    Hello! I was just wondering if this mosasaur tooth looks like it had any repair or restoration done to it. The tip is darker and in some angles it maybe looks repaired. But then it also maybe just looks like different degrees of enamel wear. Thanks for your help! Kevin
  12. Hey everyone! I made an account just to ask this question from some real experts: is this Mosasaur jaw real? I bought a tooth from the same shop and the matrix looked the same: some bones scattered about in the dirt and rock. (It’s the one right under my pinkie I’m the image) I’m a little thrown off because, well firstly, the shop traveled to vendor at a fair and that seems a little suspicious. Secondly, they’re selling other items that are commonly faked from Morocco like Trilobites. I really want this to be real but I can’t justify buying a fake…
  13. I made a trip to a different spot on the North Sulfur River this morning. I had been to this spot one time last year, but an unforecast rain shower showed up and turned the river into such a muddy mess that I turned around and left without finding anything. With a 100 degree high forecast for today, I didn't figure rain would be a problem. I found some of the usual things you expect to find at NSR, Hamulus worm tubes, a gastropod, a perfectly preserved complete bivalve, some interesting bones, and lots of bacculites. The only bacculite I brought home was the one in this photo, with

    Tylosaurus tooth

    From the album: Squamates

    A tooth from a large mosasaur that inhabited the Western Interior Seaway during the Late Cretaceous. Tylosaurus was an apex predator with thick teeth that allowed it to predate on anything in its ecosystem from large turtles to sharks. This particular tooth has clear feeding wear on the tip.

    Mosasaur tooth ID Tylosaur?

    Hello, I came across this morocco mosasaur tooth measuring 5.5 cm and wanted to ask whether it seems like Tylosaur? From what I can tell, it has no durophagous adaptations (so not prognathodon), seems to be straight instead of curved towards the tongue/mouth and lacks facets (so not Mosasaurus), and is very tall with a hook-like appearance due to a curvature straight backwards. It looks too tall to be something like Eremiasaurus, but that's just an amateur guess. If not Tylosaur, what could it be?
  20. I finally took a trip to the North Sulphur river last week. There have been a couple good rains so I was hoping that would uncover some stuff. The last couple of trips in 2021 were terrible. All muddy and picked over. This trip was still pretty muddy and little in terms of quality mosasaur material. However I went low and found a lot of smaller material. I wonder if the recent muddyness of the river is due to the lake construction or if the river just hasn't had enough rain lately? Is picture 2 an enchodus jaw? I believe the pictures of item 3 are of a really chipped pi

    Cretaceous fossils ID

    Two pictures of some finds from my recent trip to the W.M. Browning Cretaceous Fossil Site. I'm pretty sure the right tooth in the first pic is crocodilian but I'm thinking the left tooth might be mososaur. Any ideas? Second, the bottom pic is what I believe to be 2 pieces of corprolite, any ideas on this one as well? Thank you
  22. The best mosasaur material from my Holden Beach, NC trip! Top left two bones are prognathodon jaw fragments, top right three bones are vertebra, bottom left three bones are ribs, lower right two bones are from the flipper. For scale, the two largest mosasaur teeth are ~5cm each. Btw about a third of this stuff ppl had walked over or picked up and tossed aside..

    Russellosaurine tooth

    From the album: Squamates

    This small tooth is likely from a juvenile small, early mosasaur. In just a few million years, these aquatic reptiles would diversify and grow to large sizes.
