I found this nice chunk of mosasaur (?) bone over the weekend at the North Sulphur River in Ladonia, Texas. It has beautiful black enamel on each side that is very smooth and shiny. It has a bowl shaped curve to it on one side. I was thinking it was a rib chunk, but I wasn’t sure with it having the curve. What do you all think? Thank you in advance!

I managed to get in 3 hunts on my 14 days off from offshore this time. I found more artifacts than fossils but I did manage to find a nice Mosasaur vert, shark teeth and a really old coke bottle. This is a mix from Post Oak Creek and one more creek that I hunt. I gave away all the teeth except for the perfect ones to my buddy since it was his first time ever hunting.

Hello. Just another mosasaur jaw thread! This one puzzles me a little. Obviously it has the replaced teeth, as usual. But it doesn't look right to me. For starters, all of those straight edges. It looks an awful lot like a composite. Almost like three or four chunks of jaw cobbled together with some random skull bones. Am I being paranoid, could these be natural breaks? My experience tells me that jaws don't break along these straight lines, but I thought I'd throw it out there to see what people think. Thanks for your help.

Recently collected a few mosasaur teeth near Bakrit Morocco late Cretaceous

Hi all, At the local market yesterday I bought these 4 teeth (in total for a very low price). All 4 are said to come from Morocco, but the seller didn't say the exact location. But I suppose that they are either from Kem Kem or Khouribga. Anyways I would just like your opinion on them (what species, 100% original or slightly reconstructed, anything I could do to "improve" them, etc). Thanks in advance! Best regards, Max Tooth #1: sold as a spinosaur tooth (so I suppose it's from Kem Kem).

Greetings! I recently found this partial (what I believe to be) Mosasaur tooth and the texture of the enamel isn't typical of the Mosasaur I have found. I was wondering if this is consistent with any particular species of Mosasaur or if it's just a different type of preservation than I am used to. It was found in the Monmouth County NJ Cretaceous and the bottom part of the tooth is broken. Thanks in advance for your help! -Frank .6 inch Two cutting edges

I started working on a Mosasaur snout end, and so far it is coming well. I have been running into one issue though with starting to use a sandblaster, and that is that I can't figure out how to clean the extra dolomite off the piece when I am done. I have tried blowing it off with an air compressor, which gets most of it, and using water, which has caused some problems. The water seems to get into cracks and destabilize the matrix, leading to breakage. Any ideas? On this one it dissolved some elmer's glue that was used in a repair, and on some trilobites it broke the matrix. Thanks! Nathan Progress so far.

I headed to the North Sulphur River last Friday and found a magnificent coprolite in situ in the otherwise soft gray shale. I cleaned it up a bit, but as with most fossils from the NSR, the surrounding shale largely flaked away leaving the nearly 15 pound coprolite a fairly solid mass. Coincidentally, I had found a large isolated mosasaur tooth only a few feet from the spot two weeks prior. I positioned the tooth in one of the empty sockets and it would appear to be a fit. There had been a fairly good rain in the interim that looks to have dissolved a good portion of the matrix previously surrounding the chunk. My original instinct was that it had been deposited by a mosasaur, but the teeth marks in the jaw section look more shark-related to me. Too bad there's not a Coprolite of the Month. I am guessing that I might have a pretty good shot at it. Not quite the distinction of Vertebrate of the Month, but it's a start.

I got this jaw in the post today. It's 26 inches long, and seems to be the upper left jaw of a large-ish mosasaur, perhaps Prognathodon? The teeth don't provide much of a clue, since the crowns are, sorry to say, all added in afterwards. I knew this when I bought it, and I paid what I consider to be a fair price for a jaw of this size with botched-up teeth. My aim is ultimately to extract it, and mount it. At that point, I can sort the teeth out to a better standard, and replace the worst examples. I'm interested in any thoughts about the jaw in general - whether you see any obvious signs of tampering or anything unusual. I really wish people wouldn't interfere with these fossils to begin with! Thanks.

REAL? 3 Mosasaur Roots on Matrix
keithmegalodon posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hey TFF, I know these mosasaur roots can be quite tricky to see if they have been restored/ faked roots or if they are real (well at least for me it is ) I found these mosasaur roots on matrix with the plaster to protect it and is being sold in a reliable website but was wondering if the roots of these teeth have been faked or if they are real. I just really like this piece and would really like to purchase it. Thanks guys.

Here's some of my best Texas teeth. All personal finds except for the partial Tyrannosaurid tooth. The little red tooth on the bottom is also Mosasaur.

So I've gotten myself into an extremely rare deal- a mosasaur and pliosaur tooth both in the US for a great price. The goodies arrived today, and I might as well show em off. First off, we have a mosasaur tooth from the Ozan Formation of Fannin County. Knowing that the NSR flows inside Fannin County and is also part of the Ozan Formation, This tooth is probably also from the NSR itself. Although the seller didn't have time to do a full ID on the tooth and simply labeled it as unidentified, by extensive comparing with other mosasaur teeth from the area, I can promptly assume that this is cf. Tylosaurus proriger, meaning that after 11+ years of my life, I finally have a T. proriger tooth . Next, we got a tooth that has been sought out for by countless collectors- a north american pliosaur tooth. As with other Texan pliosaur teeth, this one was from the Britton Formation near Dallas. Again, the seller labeled it as an unidentified pliosaur. This time though, IDing is difficult. Based on my knowledge, the two possible candidates are Brachauchenius lucasi and Polyptychodon hudsoni, which both have been found in this area. But as its hard to tell the difference between the two in teeth, I can't make a solid pinpoint. Maybe I'll just be biased and label it as cf. Brachauchenius lucasi because brachs are more iconic to me and due to the unstableness of the polyptychodon taxon. Although not as large as other's tylosaurus teeth, this one still kicks over 4 cm which is still pretty big to me. The pliosaur tooth is just over 2 cm, making it quite small but worth due to its rarity.

Here's a few of my finds from my last couple of Northeast Texas creek hunts. It's been pretty slow but I'm trying again tomorrow. I did find a killer Ginsu shark tooth and cool fish vert with partial process. I didn't know what the little penny trinket thing was until an older gentleman told me lol. The one vert with four pics is Pleistocene but I have no clue from what. We did find a large nest of cottonmouths where two males were fighting for a large female. We saw herds of wild hogs and had quite the kayak adventure. One kayak trip was 5 miles deep in the woods where we had to go over 7 log piles with the kayaks. I'm also unsure what the little white tooth is with multiple pics by the trinket. It has thick enamel whatever it is. Hope you enjoy the pics.

What kind of mosasaurus vertabrae might this be? What possible species? ( sorry about not posting this in my previous post )
-
Two Mosasaur jaw sections arrived today. They are marked "A" & "B" in the photos. Each is approx. 4.5 to 5 ". Please look them over and comment. Including, but not limited to; accuracy of ID info, life position of each section (upper/lower, right/left), how you would proceed with additional prep (if any). Info from the seller: Halisaurus; Upper Cretaceous, Maastrichtian; Ouled Abdoun Basin (phosphate beds); Oued Zem, Morocco.

Hi, Im new to the forum and was happy to find it. I'm an amateur geologist, and fossil collector. I have excavation experience in late Roman early Christian archaeology in Winchester England back in college, so I still have my trowel and dental tools Now I enjoy the hobbies with my son when we take a break from life in Manhattan, New York City. I purchased a Mosasaur tooth , from Morocco mines and in the matrix that it came with I was able to expose another tooth....but what is it??? Its 1.5 in long including the root. I kind of like the specimen as a clump rather than just two teeth so I stoped exposing more. Any help greatly appreciated.

Hello, everyone. Thanks in advance for any help you can offer. I found this fossilized bone in a creek outside of Austin. On a separate occasion I found a very nice Mosasaur vert in the same area (literally a few feet away from where this was found). It looks to be a vertebra, but two people (Paleontologists) have looked at it, but feel that it's NOT from a Mosasaur. Possibly from a turtle? Can anyone offer any thoughts?
