  1. Due to the hurricane I got an extra day off from offshore so I hit the North Sulphur River for a few hours. I found a nice big Tylosaur vert, small mosasaur vert, fish ribs, arrowhead and a big Native American chopper tool. The arrowhead is ugly but I like it lol.

    North Sulphur River Bone

    I found this bone today at the North Sulphur River Texas. I think it's a type of mosasaur bone based on weight and color but I can't tell what it is.

    Short NSR Hunt!

    I got in a 3 hr hunt before the rain and flooding. Once the water started coming up I had to make a quick exit but still got wet. I managed to find a few things.
  4. Hey everyone, my name is Joe and finally joined the Fossil Forum website, ive been on the Facebook group for quite a while now so figured why not give the site a try. I hunt the North Sulfur River for Western Interior Sea way Material and find Pleistocene material. I also hunt Creeks in the Metroplex itself and also find Shark teeth and other bone when in Florida on Vacation. I love finding Mosasaur vertebra particularly big ones. I'm sure they're other Sulfur hunters on here so look forward to connecting and sharing my love for fossils with yall.

    I'm Back!

    I had a great day on the North Sulphur River Texas. I kayaked a few miles but found most of my quality items right by the first bridge and surrounded by tracks. The shark verts were in situ coming out of the clay. I only found 3 but I feel more will come out with another rise. I will come back and check the location. The big piece of turtle shell looked like old metal in the water so I'm sure people had been walking over it. The mosasaur tooth is nice but broken on one side. The artifacts were a nice bonus.

    Tethysaurus?

    Hello! Just after some opinions on this. The teeth look a bit like they belong to Tethysaurus but I'm not 100 percent sure. I'm still getting to grips with mosasaurus etc! It seems to have an okay amount present within the rock. Jaws, sections of the skull, some vertebra. Does it look good or another potential composite? To me it looks pretty natural, however some composites are getting good these days! Thanks for the help, I'm still learning what to look out for!
  7. I walked in tracks all day hunting but still managed a few finds. I really like the coprolite full of little fish bones and the Pleistocene horse ankle bone. I believe the little fish jaw is Saurodon.
  8. I'm interested in this skull, I have always wanted a Halisaurus specimen! Region -Morocco, Khoribga Size- 16.93 Inches This skull looks good to me, but is obviously missing parts, such as the rear of the lower jaw, some teeth, areas around the Eyes2. I'd like to get people's opinions if possible? The seller is very honest, and trustworthy in my opinion, The skull does look like its gone a few rounds in a ring, however this is my holy grail and something I've wanted since being a kid! which is what its all about right? However, I don't want the 5 year old within me to make silly judgments as it is listed for just over a grand. Is the skull a composite? Worth restoring myself? Genuine but rough? Worth obsessing over? I know it's one of those things were people will say "well it all depends on how much it is worth to you" however I don't want my naivety to cause me getting ripped off. Thanks for the help!

    Mosasaur jaw fragment

    From the album: Denton County, TX

    9-28-18
  10. Hey guys. Newb here. I picked up this mosasaur tooth at a local shop today, I’ve read through the forums about some fake settings with the jaws and whatnot but was wondering if just from the pics if anyone can tell me whether this setting with the root looks real, or did i just buy some teeth set in a fake mold.
  11. Looks like a complete fabrication, barring the crowns? @Tidgy's Dad @-Andy- @Troodon
  12. Hi everyone, With this thread I wanted to start a discussion about what the feeding habits would be for most mosasaur species, how you think they would have fed. I personally love mosasaurs, they are one of my favorite prehistoric animals for a number of reasons and I’ve recently even bought my first Prognathodon jaw and I also live in an area that is not only known for their fossils but also for the discovery of mosasaurs. I’ve been doing a bit of reading lately about mosasaurs but I can’t really find anything difinitive on their feeding habits. Their diet yes. But exactly how they consumed their prey, not yet. I personally work with reptiles on a daily base, both with my job and with my hobby and I know quite a bit of different feeding behaviours with these animals. And as I was feeding the ball pythons (Python regius) at work I was kinda wondering, how would a large marine reptile like a mosasaurus eat? Would they just tear off chunks of meat like their closest living relatives the monitor lizards? Or would they perform deathroll like crocodiles do to tear of chunks of meat of their prey? Or when we talk about smaller prey, would they just swallow them whole like a snake does with it’s two lower jaws that can move independently, would a mosasaur be capable of that? Or would it be a mix of all those things or something entirely different? So I was just wondering what are your thoughts on the subject? I love to hear your theories and own finds and observations or if anyone ever read something in a scientific paper about the matter. I am dying to know your thoughts on the matter, as I want to learn as much as I can about these magnificent beasts!

    Mosasaur tooth with replacement tooth

    From the album: Marine reptiles and mammals

    Mosasaur tooth with the replacement tooth still in place. I always wondered what the weird round/oval holes were on the side of mosasaur roots. Finally it all falls into place!
  14. Hi everyone! I know mosasaur teeth are fairly common and you can pick them up really cheap, this means they're not usually faked. I was wondering what makes the price of a jaw vary so much? I won this as an auction so the price doesn't necessarily represent quality but I was fairly sure it's real. Certainly the teeth seem to be. However, I've heard the jaws themselves can be made and the teeth then set in to it. As there's not a lot of detail to go on, is there any way of authenticating them? I'm really happy with what I've got regardless. Aesthetically it's a nice jaw. I can't find any for sale that are identical at least! Any tips appreciated! Thanks.

    Mosasaur premaxillary bones

    From the album: Marine reptiles and mammals

    2 unidentified mosasaur species' anterior end of premaxillary bones. One with teeth broken off just beyond the skull, and the other has 2 remaining teeth, with the rest broken off at the level of the skull. the larger fossil was found in the phosphate mines of Khouribga, Morocco. ive since lost the information for the smaller fossil, sadly.

    Mini Mosasaur collection

    From the album: Marine reptiles and mammals

    A little collection of assorted mosasaur fossils from 2 different places that I got when I first started collecting. 2 different types of vertebrae, one is mosasaur, and the other is a questionable claim of mosasaur, a corprolite that was claimed to be that of a mosasaur, a tooth, & 7 rib fragments. 2 ribs have predation marks, as well as the large vertebra. The large vert has a round tooth indent on the very center. The 2nd rib down has tooth scratches along the surfaces, & 3rd rib down has a round tooth indent in the center, which is probably what caused a strip across the middle to break off. There are 2 other tooth marks on that rib as well, forming a diagonal line from above left of the center indent, breaking off a piece along the top, to below right.

    Mosasaur vertebra

    From the album: In-Situ Shots(various locations)

    9-2-18 Collin County, TX
  18. I took delivery of this jaw today. I bought it over the weekend, having seen it and been offered a reasonable price on it. The initial pictures I saw were of very poor quality (the one above is mine), and it looked relatively convincing. In further photos, it also looked pretty convincing. The seller, I should point out, was not an expert or commercial seller, he was someone who'd bought it a few years ago and now wanted rid of it. Some of you are probably looking at the photo above and thinking to yourselves 'that's not at all convincing, what were you thinking?', and you'd be right to think that, since all of the teeth are fake (or rather, the roots are fake and the crowns were composited in). I've been collecting these jaws for several years, and I really should have known better. Dodgy photos or not, something doesn't look right about the alignment of the teeth or the shape of the roots. I let my enthusiasm get the better of me, as a result of which I splurged money I could ill-afford on something which is mostly faked. The jaw bone is entirely real, but there's not an awful lot of jaw to speak of. That said, it wasn't very expensive and is, if nothing else, an interesting piece of ethnographic art, and far better than those dismal $25 fakes that you see everywhere. One of the things that helped convince me was the tooth on the far left, which I felt looked quite realistic: The teeth on the right are less so, with roots which bulge in every direction, which appear to end at the point where they touch the matrix, and which in one area appear to be smudged on top of the jaw bone. They aren't the worst fakes I have ever seen, but they aren't great either. Up close they appear to be the usual mix of brown-ish plaster and sand. I post this as a warning, really. If you're ever unsure, post it here before buying, if only for a sanity check. You don't necessarily need to be a newbie to make a newbie error (although it helps if, like me, you're an idiot).

    Mosasaur or crocodile teeth?

    Dear all, I started this new topic to receive your help in identify those teeth. I bought them many, many years ago as crocodile teeth. I do not remember exactly, but maybe I bought the bigger one in Morocco (not sure!). Today I would say that are mosasaur teeth. Crocodile or mosasaur? Thank you!
  20. I have been offered this mosasaur jaw section, and am looking for some information on what parts may actually be here. There are two sections of jaw (the one on top very thin, which makes me wonder if it may be a pterygoid jaw?), although the bones on the right confuse me - are they part of the back of the skull? I'm not sure quite what to make of it, since it's not what you normally see. Based on this picture (the only one I have) I would say that the teeth have been butchered, but this blurry photo is all I have to go on. Any comments on the piece would be welcomes. I shall tag @LordTrilobite since he is very good at these things!
  21. While I was cleaning up my room, I came across this drawing of a rather elongated and serpentine Tylosaurus in my seventh-grade school binder. Thought that I could give it some light here. This drawing is unfinished, but I'm not an expert in handling antique documents.
