Another fossil from my thrift store find. The information tag said, “1950’s collection fossils and rocks-in matrix. Mosasaur vertebrae- 300 million years old. Found in South Dakota.” Is this true? What does “in matrix” mean?

These two samples were found in Gove county Kansas in the Smoky Hill Chalk formation (part of the Niobrara formation). I was wondering what type of marine reptiles they were from??? These are two separately found samples so they do not go together. They are both a little over 3 cm long.

Found this in Myrtle Beach. Thought this was a rock at first, but resembled too much like a tooth. Also, I unfortunately don’t have a tape measure or scale with me.

Hello, Newbie to this site. I appreciate in advance any help in identifying the species this belongs to. I believe it to be a Mossasaur jawbone. This was found in a bank in the North Sulphur River in Fannin County, Texas. The overall length is around 34 inches. It's not the hardest thing as you can see from areas it has crumbled. Any advice on best practices/methods to reconstruct it and make it more stable are appreciated. My plan so far is to use E 6000 clear to match and attach pieces as best I can. This was left to me by an old best friend who passed recently. We hunted this area for years finding well over a hundred mostly intact Mossasaur vertebrae, and lots of fish bones, teeth etc. This is by far the most interesting piece. Most Mossasaur jawbones that I can locate online do not have the serrated teeth on the back of the jaw. All I see are teeth that look similar to the teeth in Pic 4. pic 3 shows the transition between the serrated (Grinding?) teeth and the incisor style carnivore teeth. Maybe this species evolved to better crush Ammonites? I'm hoping someone with knowledge here can confirm it's a mossasaur, and hopefully a species ID. Is there a way to estimate the overall size of this creature, knowing the jawbone is 3 feet long? All help, comments, or suggestions are very much appreciated.

Hello! Here I am again, with 3 unknown vertebrae… I can’t provide provenance, so I don’t expect to get the exact species. But can anyone tell me from what kind of animal they were? Are they dinosaur or something else? Thank you for your time :)

Can someone help me identify this tooth? There are 4 in total, all found within 50 yards of each other near Williams, Arizona this past weekend. This one is the largest at approximately 3 1/2 inches long and approximately 2 1/2 inches wide. Very old but not fossilized as far as I can tell. I don't know what I'm looking at. I was told they were too big to be bear teeth. There are no visible serrations, they are very large and thick, with a slightly curved angle, coming to a sharp point and a flat back side.

Mosasaur - help needed what is real or fake
ray67 posted a topic in Is It Real? How to Recognize Fossil Fabrications
HI everybody, so i´m quite new in the fossil collecting business and started watching some auctions on an auction site, recently. My one and only fossil finding event was some years ago in the south of morocco with my wife in a jeep, where we could find trilobites easy on the side of the desert tracks. one of the locals also showed us the "production" of the 100´s of trilobites they sold as souvenirs, mostly made by casts... Well, what i´m looking for now is a selection of maybe a (or 2) handful nice objects of good size and quality, and one of this pieces should be a mosasaur skull or jaw. There are a lot offered these days at the mentioned auction site, but i´m really afraid that some of them are fake. so my question to you experts is - how can i distinguish between a real mosa and a pile of resin? and is the expert-estimation on cata something you can trust - at least that´s it a real dino and no fake one? i did a little research on this topic and will post 3 pics of proven real mosa skull/lower jaws from past auctions (the 3 with the blue background) at another site and after that 4 pics of 2 mosasaurs that are on the auction this week and, well, could be interesting for us if they are no fakes. thank you so far for your feedback and best regards, ray Auctions: # 1 # 2 REAL MOSASAUR JAWS -
Found this fossil in a riverbed in Fannin County (North Texas) while hunting for fossils from the cretaceous period. (This is a follow-up from the same trip as my previous post - thank you to those of you who helped ID the mosasaur vertebra! And also thank you for correcting my terminology on mosasaur vs mosasaurus ). I'm not totally sure what this is (at first I thought it was nothing too special - possibly just a very eroded Baculite as we were finding many of those in the area), but on closer inspection, there are fine striations on the fossil that make me think it is bone. My current guess (based on those striations and the longish/slightly curved shape of the fossil) is that it is a fragment of rib, and further, (based on the facts that everything else we were finding was from the cretaceous and that mosasaur are the only large marine vertebrate that I know of being regularly found in the area), that it is a fragment of mosasaur rib. However, I am not sure about this and am hoping for some more help on identifying what I've got here. I hope these photos are good enough to see the details (i've tried to shoot them in half-decent light). If you zoom in, you can see the striations I'm talking about fairly well. (See dime for scale). Here are both sides of the fossil Here are the ends And here is a closer shot of the more intact side So in summary, I'm wondering if I'm right (or even on the right track) that this is a fragment of mosasaur rib? And following that up, whether ribs are identifiable by speciesm (probably not, but worth a shot )? Final sub-question that is probably totally speculative, but I'm curious about: there are a lot of indentations and gouges in the fossil. Is it possible that these are marks from a predator and/or scavenger (e.g. sharks) chewing on the dead creature's carcass? Or is it more likely to just be erosion? Thanks for putting up with so many questions!

Found this today in a dry creek bed where I have found previous cretaceous pieces (sharks teeth). Was just laying there in some small gravel. Roughly 3 CM and some (small) change.

Is this a real Mosasaur tooth?

My friend bought a pile of shark teeth and along with it came a reptile tooth and it could possibly be a mosasaur but I am not sure. It is from Belgium

I found this down in our creek in Tennessee and thought it looked like a vertebrae, I chiseled it out of a rock and brought it home. I don't know what it is but the closest thing i could find is a small tail vertebrae of a mosasaur. I need help ID'ing this because I'm not just gonna jump to the conclusion that thats it because a lot of times its just a look a like rock, However I have handled fossils before and this feels like bone. Let me know what you think please.

We were out with the Cub Scouts yesterday at the NSR. Found this, unsure of what it is. Any help is greatly appreciated.
