Hey All, I'm doing a series of these posts so I don't overload any one post with too many pictures and so I can keep things grouped together in a way that makes sense (See earlier post on North Sulhur River identification). I've got some bones that my wife and I found on our last trip to the North Sulphur River. The first two images appear to be from either a jaw bone or a paddle/ flipper. My wife and I are in disagreement as to what part of the skeleton this could be from so I would love a second opinion. I suspect this is likely from a mosasaur or something similar. I think it is too thin for a jaw bone which is why I think it is from a paddle. The last three pictures are a half of a vertebrae that I really wish was whole, but such is the life of a fossil hunter. I've only ever found one like this and I know it is some kind of fish. I've ruled out shark and I have it narrowed down to Xiphactinus or Enchodus. Again, I would appreciate any opinions on these specimens. Thanks!

I found this today at Big Brook Preserve in New Jersey. Is this a Mosasaur tooth? Or Prognathodon. Thanks for any help you can provide. Are they any experts inSouth/Central Jersey I can confirm with?
-
I am about 84.9% sure that this is a fragment of a mosasaur tooth. However I have been wrong when trying to id Mosasaur teeth before so I just wanted a few more opinions. It is from Big brook New Jersey and was found in May 2023.

First ever fossil! Is it actually a mosasaur and what are the fragments?
Rhysand4rch posted a topic in Fossil ID
I went to a crystal festival today and a few stalls had fossils so I bought one! it was labelled "Mosasaurus, upper Cretaceous, Khouribga, Morocco" It's really neat and I like it a lot, but just wanted to see if anyone could tell me 1, is it actually a mosasaur? and 2, what are all the fragments? I know next to nothing about actual fossil identification so any help is much appreciated! if you want any closer images of a specific part of it just tell me

I found this cool jaw and I know they are faked a lot. If you can reply soon (next 10 minutes. I know it is a lot to ask. Sorry) as I am in the shop for a limited time. If it is real, what is the precise identitity?

Hello, I've just bought this 8cm long, certainly pathological, rooted moroccan Mosasaur tooth. It has some weird, standing out striations, and a split, extra carina. It certainly appears not prognathodontine to me, but it looks more like a Halisaurine mosasaur tooth in my opinion. And please let us focus on the crown, and not the possibility that the root might be fake, this time Thanks for any help ! @pachy-pleuro-whatnot-odon, @Praefectus, what would be a mosasaur tooth ID topic without your tags...

Publication - New find of Globidens alabamaensis cranial remains described from the Ozan Formation
pachy-pleuro-whatnot-odon posted a topic in Partners in Paleontology - Member Contributions to Science
Globidens alabamaensis is one of the rarest mosasaurs known from the United States of America, with most finds existing of teeth alone. In our latest article we describe newly discovered fossil remains that can be attribute to the species. https://www.researchgate.net/publication/383117647_New_remains_of_the_mosasaur_Globidens_alabamaensis_from_the_North_Sulphur_River_of_Texas Authors: @Praefectus @BrennanThePaleoDude @pachy-pleuro-whatnot-odon Abstract: Here, we report on the important discovery of two well-preserved maxillae from the durophagous mosasaur Globidens alabamaensis Gilmore, 1912. The maxillae were found in the Ozan Formation embedded in the North Sulphur River channel near Ladonia, Fannin County, Texas, USA. Both maxillae preserve nearly complete tooth rows. In North America, Globidens is amongst the rarest mosasaurs, with remains consisting predominantly of isolated teeth and jaw fragments. This has been another excellent project to work on with you guys, and I grateful to have been part of this journey! Thanks go to Courtney Travanini for making her discovery of the Globidens fossils available for study, and to Nathan Dehaut (@ekhyl_ on Instagram) for his artistic reconstruction. Left maxilla in labial view (top) and right maxilla in labial view (bottom). Associated rooted tooth in labial view. Lingual view of the right maxilla showing germ tooth in 7th tooth position.

Hello all, I have been working on this for sometime. All the fossils were found in the same place in a 2ft square spot in pierre shale in south central Nebraska. I have pieced what I was sure about (obviously keyed or "fit" together well). All were found randomly in the 2ft square location. Some of my questions are: 1- Is this a small Mosasaur or is it a similar reptile? 2- Can more of the pieces be IDed? I can take further pictures of any piece with a scale reference. Also, I will lay the pieces out and write a number next to it for clarity. 3- what is a good method of adding pieces to the skull that will be "floating" or missing surrounding pieces to attach to?

Fossil mosasaur jaw - How to tell if fake or not
Siegchomimus posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everyone, I have been looking for a while for a mosasaur jaw to add to my collection, but I struggle with the distinction between fake and real. I know there are, saddly, a lot of fake or Frankenstein fossil from Morocco. Got tricked once with a spinosaurus tooth that ended up being mostly resin and fragment of actuall fossil. The problem is that almost all the fossils of mosasaur jaws I see online look weird, uncanny, deformed, or just a photocopy of one another. It seems impossible to find one that clearly shows some bone and not glued sand shaped vaguely to look like a jaw. And even the ones that look like they are made of actual bone, look weird. I heard they sometimes use animal bones to create a fake jaw and then add mosasaur teeth...... I just struggle so much at telling if any of the ones I see are real and feel like I missed one actually real jaw on multiple occasions. Saw one online that looked good, but I still had doubt and waited for too long, and someone else brought it. Managed to save one picture of it as I wanted to look at it in detail before buying....

Found this tooth within the first 10 minutes of walking through the North Sulphur River in northeast Texas yesterday! My suspicion is mosasaur, but someone on another site cast doubt on that notion, so I would just like to confirm whether or not it belongs to a mosasaur. Additionally, if at all possible, I would love to have an ID on it. Edit for clarity: not shown in the pictures, but the tooth is fairly conical and has one blade edge, which is on the outside curve (sorry, I don’t know the official terminology). I can provide extra pictures if needed.

Hello!!! On this topic, I would LOVE to see everybody's mosasaur fossils!!!!!!!!!!!!! Here's my Halisaurus (probably) tooth fossil!

Here is a beautiful Mosasaur upper jaw with still it's original teeth. Though over the weeks had some discussions with multiple people wondering or claiming what it is. I got told: Eremaiasaurus, Prognathodon sp., Mosasaurine sp, unidentified species?, even baugei. Anyone possible to help me? Or may start a nice discussion over this specimen. Found in Sidi Chennane, Couche 3 Morocco phosphatic deposites Biggest crown measures just above 5 Cm.

Can't decide... looks like tooth enamel in spots, or maybe just another Big Brook concretion trick on the eyes. Bad shape of course.. Big Brook, NJ.

Since I have gone "down the rabbit hole" of Micro Matrix fossil hunting, I'm going to start a series of posts on the main time periods and locations I am collecting. I'll start off with the Best Of and then add in new finds. Of course, Texas Cretaceous is my primary interest, but will also have posts on Texas Pennsylvanian, Permian, Eocene and Pleistocene. Plus other posts on various locations around the country (and world!) SO if you like Micro fossils, keep an eye out for them! So Texas Cretaceous Best Micro Finds to start!

Are these Mosasaur jaws real?
M3gal0don_M4n posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi everyone. I am Back again with questions about Mosasaur jaws, only this time, same store, different products. You don’t need to get back too soon as I don’t have anywhere near enough to buy them, but depending on its legitimacy I will save for it.

Is Khinjaria acuta the rarest mosasaur in the moroccan phosphate mines ?
Brevicollis posted a topic in Questions & Answers
Hello, I have a question. Is Khinjaria acuta the rarest mosasaur to find in the Moroccan phosphate mines ? I only know that one partial skull has been found of this species so far, and I recently saw that one of the mosa experts had published two photos of a Khinjaria tooth. And now I saw an already sold tooth, that really looked like Khinjaria. Maybe I'll post about it later. -
Hello, I saw this already sold tooth and want to know the species it belongs to. It doesnt seem to match with croc, plesiosaur, or fish. The pictures of it are'nt the clearest, but Im able to spot some slight prismarism only at the base. The rest of the tooth has no prismarism, only enamel patterns. I also saw these two pictures of a Khinjaria acuta tooth, and thought when I compared them, that he might be a candidate. @Praefectus The Khinjaria acuta tooth : The tooth this topic is about :

The last 30 days have been great. Not the largest numbers of fossils, but high quality. I went to a highway median lower Eagle Ford exposure in South Grand Prairie, Texas, and another nearby Tarrant formation exposure on 3 occasions in the last few weeks. I have a lot of firsts from these excursions: unknown gastropod absolute unit of an ammonite, a 5.1 pound acanthoceras amphibolum with huge spikes concretion with conlinoceras tarrantense with original shell and septarian veins mosasaur vertebra partial (?) lobster in a pre-broken concretion metiococeras ammonite (rough one but my first) numerous conlinoceras tarrantense ammonites 2-4 inches diameter

Howdy all, Recently picked up this mosasaur tooth from the Khouribga Basin and I'm pretty sure it's a Thalassotitan atrox, but, considering there are over 40 mosasaur genera known from that locality, I'm hoping for a second opinion. Note: both carina are present and have tiny, almost microscopic serrations.
