From the album: Texas Campanian (Cretaceous)
Two Mosasaur caudal vertebrae Campanian Texas These two caudal vertebrae, found in the same stream, demonstrate some of the size variation seen in mosasaurs. Notice the two pits of the bottom vert - those are for the haemal arches, and with no other bony attachments except for the base of the neural spine (on the other side), we can infer that this vert came from close to the end of the tail, probably putting its owner in the 30+ foot range. Alternatively, though very worn, it seems that the smaller vert came from a position closer to the pelvis (though still caudal). Likely from a juvenile of what had to already have been a different, very small species.- 1 comment

Recently I took a trip to a new spot in the Maastrichtian of Maryland. I did not manage to recover too much vertebrate material, though I have been quite intrigued by one piece that I collected. The main question regarding this piece is whether it is bone or whether it is simply a suggestively shaped rock. If it does turn out to be bone, would it be possible to determine what it may have come from? The main marine reptiles that are recovered from these deposits are mosasaur and marine turtle. A few photographs of the specimen in question. If better photographs are needed/photographs from a different angle, I would be more than happy to attach some to this thread. Thanks in advance for all suggestions and opinions!

Mosasaur Skull I’d like to acquire
JJ Lavoie posted a topic in Is It Real? How to Recognize Fossil Fabrications
This is what is said to be an authentic mosasaur skull being sold from the location of MOROCCO. They said it was glued from the fossils found at the site. I am really interested in buying it but know they love to fake some fossils there. It doesn’t look like the terrible alligator looking ones I see on online auction site and around other sites. Matches what they normally look like but am not sure if anyone can tell from the pictures provided.

The jaw looks 50/50? Looks like theres erosion. Im stuck between fake and real. The teeth all looks set in.

Khorigba, morocco looks like matrix instead of jaw.

Jaw looks real but it doesnt look like it belongs to globidens. The globidens teeth look haphazardly slapped into the jaw. khourigba, morocco

12.6" Mosasaur Prognathodon Fossil, 2 lbs 6 ounces, 4.7 inches wide, 1.5 inches thick Location- Qued Zem, Morocco Seller doesn’t mention anything about repair or restoration so I’m not sure about that I’m wondering if it’s restored. Are the teeth original to the jaw? And are those bite marks

Happy almost Halloween! Show us the scariest thing that has ever happened to one of your fossils or something about fossils that is related to halloween. Mine is this. I'd bought a fake mosasaur jaw but I didn't know it was fake. I'd put it in the sink to clean it off and then the whole thing crumbled. I did get some mosasaur teeth out of it though.

Hello everyone! Yesterday I got a chance to dig in one of New Jersey's famous Cretaceous streams. Once again I planned out a fossilhunt to coincide with my Son's Marching Band competition at Metlife stadium. I have been doing this the past few years as a way to kill two birds with one stone. My wife and I left our house in New York around 5:15 am and arrived at the stream around 10 am. Since my wife has no desire to climb around a stream getting wet and dirty, she left me for a few hours to go shopping. I will say that I had low expectations for this trip. The past few years I have been finding less in the streams. They have become increasingly popular and get searched very hard. I chose to go to a spot that @frankh8147 took me to a few years ago. He told me that in his experience, it produced more reptile fossils then other areas. Indeed i ended up finding my first small complete Mosasaur tooth there the following year, even though i have been hunting these streams since 2006-7? Though that tooth was much smaller then what would come on this dig. So i started off digging in a particular spot that i happen to like. I found a couple small decent sharkteeth right away. I thought to myself that this was a good sign. Well i dug this particular spot for awhile and all i got was small broken bits off sharkteeth for the next hour. So i started randomly picking new spot to dig and things were not looking good. Absolutely nothing. Then i noticed a small gravel bed that was wedged in between some fallen tree branches. I decided to give it a shot. After a few scoops of gravel in the screen I wasn't finding anything. I almost decided to move on, but I had a nagging feeling that I should stay just a little longer. Then after a couple more scoops I looked down a saw a nice mosasaur tooth! I was very excited as this was alot bigger than the first one I found. It has a little tip, and cutting edge damage as well as some missing enamel but from the teeth that I have seen come out of these streams, I am happy with it. After this I decided to dig in this spot longer. I found what I believe to be a beat up crocodile tooth as well as a chunk of rock with gastropod impressions and molds. After this things went dead. I moved around checking other gravel beds and didn't find a scrap of anything except bits of belemnites. I guess this goes to show that even when you think everything has been picked over, sometimes perseverance pays off. Here are some pics

I recently received some American Mosasaurus (and other) teeth. I would like to identify this, but that is proving difficult. Hopefully we can figure it out together. Tooth number 1, maybe Mosasaurus missouriensis? length: 1.5 centimeters Origin: Tombigbee river, Monroe county, Mississippi, USA Period: Eutaw formation, Cretaceous

Trio of mosasaur teeth in matrix
Georgemckenzie posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hiya everyone I’m interested in this allocation of mosasaur teeth I know the roots are often faked so any help would be great.
-
Hi all - found this in Central Texas. It was a surface find in an area mapped as Ozan formation. Thought it was an old railroad spike at first. Is there enough left of it to give a general ID? Kind of looks like some mosasaur vert pics I’ve seen. Any ideas appreciated. Thanks!

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.

Hello!!! On this topic, I would LOVE to see everybody's mosasaur fossils!!!!!!!!!!!!! Here's my Halisaurus (probably) tooth fossil!
-
This is our collection so far of our favorite finds. All found at Holden beach. Pics consist of shark teeth, mosasaur teeth, horse teeth, sloth tooth, barracuda teeth, stingray teeth, sawfish teeth, enchodus teeth, enchodus jaw fragments, scute, ivory, mouth plate for puffer fish, shark vertebrae, mosasaur vertebrae. We accumulated this in 10 months and they were the best 10 months. My next goal is to start searching creeks. I'd love to dive too. Lots of different adventures to look forward to.

I took off early last Wednesday morning and drove to the North Sulfur River. I hadn't been there since early in the year and wanted to see it again, even though I knew that after such a long dry spell, it might be tough finding much. That thought proved to be right. The stretch of river bed I walked was completely dry, and had obviously seen lots of visitors. I hiked quite a distance, slowing down in all the areas that had been productive in the past, but picked up nothing. So I put on the kneepads, and began searching for smaller fossils. I've always had a tough time hunting NSR for small stuff. There are Hamulus worm tubes everywhere, and I always have to pick up some, but finding anything else small is always hard for me, and Wednesday was no exception. It was slim pickings. But I did have questions about a couple of the things I did find, so I'll post this report. Here are some in situ photos.

Mosasaur: Hainosaurus Skull - Curious on further input
gigaman posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi All! I once again come to you for expert opinion and input on a Mosasaur skull/ The anatomy is a bit more accurate, but I cannot say for sure if it is a genuine fossil. Any insights would be much appreciated as far as if this is a composite specimen or looks to be from the same extraction (which I doubt) I am mainly curious if the majority looks authentic or somehow synthesized. Also the seller identified this as a Hainosaurus: the slender skull seems accurate but the teeth running to the end of the snout does not align with popular scientific finding/opinions - gives me reason to believe that the fossils may be authentic but a composite of a few specimens. Would love any and all opinions as I am interested to know if there is any authenticity to this specimen. Thanks for any and all input in advance!! Pictures below:

Hello! I am trying to clean this beautiful mosasaur pictured below, but I am really struggling with some old paleobond thats already been used on it. I have been somewhat successful with using a liberal amount of acetone on the bone, which I scrub in with a toothbrush. This has worked, but there are certain regions where the the glue was used on gypsum crystals and model clay, which has effectively cemented the bones of the lower jaw together. I've also been using a regular paleoarrow. My goal here is to get it as clean as possible, NOT to specifically separate the natural occlusion of the teeth. The plan is to display it at a museum (Also, any wild guesses as to the genus of this pretty lady? I was thinking latoplatecarpus)
