    Mosasaur vertebrae??

    Hello, I'd love to know your opinion about these reptilian vertebrae coming from the lower santonian of northern Spain. Fisrt photo is view from above and second from beneath I've made some guesses about this piece, and I hope some of you could give me your opinion about them. Here come muy guesses: -Taken that it comes from clear ancient marine strata, its general morfphology and its Santonian age, I think it probably is a mosasaur vertebrae. The problem is that there hasn' been any mosasaur reports in these places, basically because vertebra
  2. Perhaps the most definitive, lasting project I've had during my short time in paleo is the excavation and study of a basal mosasaur skeleton my step brother and I found in September of 2021 (If you missed it, it's in my blogs on my profile). The site is on a fairly inconspicuous outcrop of the Eagle Ford formation, in a zone that's atypical for the upper eagle ford, as the rock itself is very condensed compared to what is usual for the upper kef. Notably, while Mosasaur material is very, very rare in the kef (kef is an abbreviation for the Eagle Ford formation), it pokes out with greater frequ

    From same creature? SD

    Found these 3 fossils 1ft apart from each other at bottom of a hill. Are the 2 vertebrae from the same area of the body as the mosasaur paddle arm bone? What's the chance this is all from same 1 animal? If so I might try looking for where they came from. Is there a technique to removing a side of a hill to find the source? Thanks

    Mosasaurs #5

    Hi guys got a few more for idenitification thanks for your help 1. this was broken in shipment and is completely hollow even the root is this normal? The rounded cross section makes me think T.atrox 2. slightly more compressed, eramiasaurus? 3. gavialiminus? 4. another gavialiminus, any idea why both of these are so compressed? Preservation?
  5. Hola, necesito ayuda para poder determinar la especie de este fósil, procede del sur de Marruecos y está encajado en una pieza de 155cmx 113cm, sabemos que petenece a la familia Mosasauridae pero tenemos dudas con respecto al género y si es un adulto o una cría. (Translation added and post moved...) Hello, I would appreciate your help to identify a fossil, it comes from southern Morocco and is embedded in a bed of clay, its measurements are 155cmx113. We've been told it's a Mosasaurus, but we have some doubts about the genus.

    Mosasaur spine

    Hello, I have found in a shop this "mosasaur spine" fossil. Is it a mosasaur? For what I see the vertebras are procoelous which is what you would expect, but I would like some expertise council on this. And moreover is it possible to identify the which type of vertebras are those? And to which mosasaur they belong? The full plate measures 55cm x 20cm and each vertebra measures 8-9cm more or less. It's from Thanks! Edit: It's from morocco.

    Ramanessin Bone Id

    Hi all, me again, I wanted to share a closeup of the bone fragments that I found in Ramanessin to see if I could get them ID'd further since I know how the brook tends to make fake fossil bones i want to check that the ones I found are real fossil bone 1) the big one, i think it might be a cretaceous turtle shell, it passed the burn, and the lick test. 1A) I believe these are also enchodus jaw fragments. 2) 2A)

    Ramanessin reptile Tooth ID

    Here are the two fragments I found in Ramanessin of what i believe to be mosasaur. the right one im unsure of, i still think its a cretaceous reptile. the left one, I am more certain is a mosasaur. but let me know what you think!
  12. Stick around, this one's a read but I'll try to make it fun. So, I have been to big brook last year, and While I enjoyed it, since I went in early feb, the ground was frozen which prevented me from finding much, as the brook was stingy that day. Nonetheless I decided to try my luck with Ramanessin as i heard good things about it. Because none of my family or friends could be bothered, I decided to take a day off work and drive 4 hours to the area and spend the night so I could get the most out of the location. what follows is the result of 2 days straight of fossil hunting. which I

    Globidens alabamaensis

    From the album: Ozan Formation

    Globidens alabamaensis, NSR Campanian, Cretaceous Mar, 2023 A shell-crushing mosasaur not uncommon for the NSR. They first showed up in the Early Cretaceous, shortly after the disappearance of ptychodus from the seas.

    Tylosaurus proriger

    From the album: Ozan Formation

    Tylosaurus proriger, NSR Campanian, Cretaceous Mar, 2023 A fantastic mosasaur crown from the renowned NSR. Complements my rooted tooth well as that specimen is beat up around the crown.

    Mosasaur Jaw

    Hello, I bought a Mosasaur Jaw fragment from Morocco at a local expo, at first sight I thought that maybe it's prognathodon sp. but I would like to know your opinion. The jaw has 3 teeth that I could check that belong 100% to the jaw and the other at least seemed to have the same morphology but it's not possible to know if the belogned to the jaw or not. Any way, knowing this I thought the price was fair so I bought it. I have marked with red the teeth that for sure belong to the jaw so it can help with the ID. If it helps with the ID, the teeth have 2 edges, one on each side. On t

    A Classic Hunt on the NSR

    I think North Texans will relate when I say that now and then, the urge to take a drive out to the NSR and spend the day hunting some Campanian gravel bars can spontaneously take complete hold. I had one of those moments just after the series of heavy rains and powerful winds our region encountered some days ago. Previously, my luck with weather at the NSR had been rather poor. Each time, the temps were either nearing a hundred degrees or only just above freezing, making a full on adventure crossing muddy waters and crawling atop unshaded gravel beds too much to handle. I had yet to experience
  17. I was finally able to take a trip to the NSR in 2023. We had a good 11 foot rise so I was optimistic. My whole goal this trip was to find a point, I couldn't find one to save my life, I however did find a few cool fossils. I don't know if i just don't have the eye for it or if i am just looking in the wrong places. The last two pictures are of an item im not sure about anyone have an idea? Possibly a set of fused vertebrae with the two end ones broken off? The haul The vert The mosasaur thing The in-situ
  18. Found on Holden Beach, North Carolina. If you need certain measurements let me know, thank you.
  19. Hello everyone! I just got some but I have no idea about it.The only information that seller gave me is those mosasaur bones from Ozan fm, Texas. So I will post some photos of them for you to have a look if you familiar with them and can tell the ID. here are they: Bone 1: Bone 2: Thank you!

    Anyway to identify some isolated mosasaur teeth? I got these from one of those little fossil kits when I was a kid. I'm assuming they're from Morocco.

    Mosasaur tooth id

    Hi. New collector here and first time here at the forum. Im trying to collect some mosasaur teeth and realized that Im unable to recocnize Eremiasaurus heterodontus tooth. My first thoughts with this tooth was that its an prognathadon kind tooth (Thalassotitan), but I could use some help so I know was my first thoughts wrong and how I recognize the Eremiasaurus tooth in the future? Never seen any and don't know what too look for. Tooth is 3cm. Quite smooth cutting edge on a front. Moroccon. Thanks for the help.
