I went to the Ramanessin brook a few months ago for the first time, while I was busy looking at my cretaceous shark teeth I completely forgot about this thing I found. To me it looks just like a bone but I have never found any type of bone in New Jersey before, I'm curious if it is one. And if it is, is it possible to identify what this could possibly be from.

Hey all. Seems with me not getting out to the river today, due to finally having some rain, I was looking at my verts. I assume the different shapes are due to different species and not age as they vary a lot. Is there a site or book, or something that has a listed with pics of the differences? I would like to see if I can label any of the 50+ to keep them together. Thanks for any help.

Hello, Is anyone able to narrow this down more specifically? It is listed as end of a Mosasaur jaw---but if someone can narrow it down to a species, that would be great. No teeth unfortunately. I'd quite like it, if a species can possibly be narrowed down becaause then I can display it alongside the teeth. I got one from the same seller, with a tooth that was ID'd on here as Prognathodon which looks similar. But, I figure it best to post it in case this is from a different, similar species. it's from Khouribga, Morocco. Height = 4cm, length=8 cm, width=5cm Thanks

Here are my finds from my latest POC visit. Made a decent haul with my best Ptychodus yet and my largest tooth so far here. The tooth was about 1.5 inches. I also found a small ptychodus with no root but it did have very defined grooves. Pictures 2 and 3 are the large Ptychodus and picture 4 is the 1.5 inch tooth. 5 and 6 are the small Ptychodus. Picture 7 is the creek wall matrix I was looking in for teeth and 8 and 9 are the actual teeth I found in the matrix. Does anyone know if this is original matrix? I was able to find several teeth sticking out but several of them were also just pieces of teeth, like you find on the gravel bars, and not complete intact teeth. I was hoping if they were from the original matrix the teeth would be complete. And Finally I have a game for you. See if you can find the tooth in picture 10. For some reason many of the teeth I found this trip were highly camouflaged haha. The rest of the pictures are just closeups. I initially thought I found some mosasaur material but the bone feels modern to me now that it is dry. I also found my first vertebrae this trip. Looking at the other posts it seems like verts and artifacts are pretty easy to find but I guess I just don't have the eye for them as I have only found this one vert and have never found an artifact. Enjoy. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14.

Here are some finds from two trips in early November. Several ptychodus with one nice large one, a ton of shark teeth shards, a couple pieces of mammal enamel, and some unknowns. Im posting the shark teeth first and then will post the pictures of some of the others. Let me know what you think. Anyone know the species of the teeth in picture 1? I was specifically wondering about number 3 from the first picture. Pictures 6-10 are closeups. 1. 2. 3. 4. 5. 6. 7. 8. 9.

Here is a trip I took to the NSR back in 2008 and had some great finds. Many bones and a good Mosasaur vertebrate. I don't know what is in the top center of the last two pictures. Also a tooth of what appears to be a fossil of a more recent mammal is right under it. Any ideas on either one? Sorry I didn't use anything to scale but it should all be pretty typical of the type of fossils from this area.

Howdy! Took a quick trip up to Dallas last week (kitten transport to two lucky families!) and I got a little fossil hunting in as well. The creek was Woodbine Form. Found this partial vertebra and was thinking it was mosasaur (FINALLY FOUND ONE! even if it is pretty banged up) but a friend says maybe not? Any thoughts? And also found this lovely little shark vert. Any way of telling what kind? (I think it's a shark vert, anyways. I might be wrong...lemme know!) Measurement in Inches

Hello everyone, i saw this on a auction site. Looks really impressive and legit. But I have some doubts if the work that has been done there is good or not. Do you want think teeth or anything elsewhere are fixed with composite ? if anything seemed weird to you, I’ll be happy to know thanks in advance

Good afternoon, fossil friends! This post is a bit of a long shot, but I figured I’d rather ask than not! This may be the incorrect thread to PLAN trips, so if it is, please let me know and I’ll delete it! I certainly intend to share some stories from past trips, but I’ve found myself with free time Wednesday in the first half of the day and I’d love to go on an adventure fossil hunting with someone who is also available, should anyone be up for that! I’m also down to plan future trips for other dates! I live in Denton county and I’m more than willing to travel a couple hours for a productive site! I myself have only explored the well-known north Texas sites such as Mineral Wells, Post Oak Creek, and Lake Texoma. If anybody would like to go there, NSR, or any other places they know of, it’d be really cool to explore with another fossil fanatic. My girlfriend is a great partner, but I always feel bad boring her with my rocks! Plus, I haven’t gotten to explore or learn as much about the fossils of this region as I’d like. I was a part of Dallas Paleo for a while, but after moving out of my parents’ house I haven’t had the time to rejoin, but hope to in the future! For now, I’d like to take some of my free time to learn with other paleo nerds when I can. Please reply if you’re interested in meeting up sometime and heading out to find some ancient friends!

Hello everyone! I just acquired this piece but the only thing I know is that it's a mosasaur from morocco and it shows the lower jaw and the pterigoid teeth from the upper jaw. Can any mosasaur experts here help me identify the species? I'm thinking of prognathodon maybe?. Also as far as I know it's not fake or composite but would be great if you could confirm it. Thank you very much for your help, very appreciated! Greetings from Spain.

NJ Cretaceous Mosasaur partial tooth and Enchodus or X-Fish fang?
Fishinfossil posted a topic in Fossil ID
Morning out a few weeks back in NJ Cretaceous streams and found what I think is a enamel chip from a mosasaur tooth. The other appears to be possible fang from Enchodus or X-Fish? Any confirmations on either of those? Thanks. Please excuse picture clarity, just have Iphone today.

This post series will attempt to illustrate a minor prep project of a Moroccan mosasaur fossil. It is hoped it will encourage others to attempt a similar project, using simple tools. Thanks to Forum members @DPS Ammonite and @LordTrilobite for their helpful pre-acquisition comments. Special thanks to @jnoun11 for his ID verification of the piece and clarification of the fossil's precise place of origin. The Moroccan seller listed the fossil simply as "Mosasaur, 9 cm X 6.5 cm, Cretaceous, Khouribga, Morocco" Here is a photo from the seller. Note the large coprolite resting beneath the rearmost tooth. Unfortunately and not unexpectedly, the piece arrived damaged. At first glance it did not appear too severe. However close inspection revealed cracks in the matrix that ran to and beneath the two rear teeth. As an interesting aside, the break in the coprolite revealed an internal color pattern. To be continued.....

*Just a note that this is a follow-up post to the VFOTM post that I wanted to share.* After reading a few posts here on the forum I decided I’d go to the NSR when I got the chance. I’d read it was good for beginners and the opportunity presented itself in April, 2020. I decided I’d make the trip and see what I could find. The first trip I hunted I found very little and walked a great deal until the very end of the day when I finally found two small mosasaur teeth. One of which was a Globidens sp. I was instantly hooked. Two weeks later, on my second ever fossil hunting trip I spotted the exposed section of the tip of the dentary which was only an inch above the marl, and kept walking thinking that it was just wood sticking out of the riverbed. Keep in mind it was after a two hour drive and seven hour hike, I hadn’t read much about fossils, and had no idea about how to properly collect a more complete vertebrate. I continued walking and my exhausted heat addled brain finally processed that the chances of there being an old black piece of wood stuck in the bottom of the riverbed wasn’t that likely. So I walked a few yards back and was lucky enough to find it. Beginners luck! I didn’t take a picture of it until I exposed the first tooth. First picture though is just the anatomy of my find as I understand it. This was the first picture I did take of the right dentary. The NSR can rise pretty fast, especially when it’s raining out west and it was slowly rising so my find started going under water. I was stuck between trying to get it exposed and out of the ground in as best shape as possible and risking it going under which I didn’t know how would effect it. To top it all off the only tool I had was a screwdriver. Here is the dentary nearly exposed. And exposed. I dug a little channel that diverted some of the water away, but it was only effective for a few minutes. And here’s the shape it left in the river bottom. By the time I had the find out of the ground the water level was well over the site and the sun was going down. I decided I'd go back as soon as possible to see if I could find any more.

Hi again. I have another one for you. I think I could tell if it wasn't broken! Found in green mill run. It is 1.5 inches or 3.8 cm. There is a definite ridge on one side. I tried to get a good picture of its location, the cavity seems slightly oval. Thank you again! I really appreciate you all teaching and helping me!

How were there so many mosasaur species in the same place? Niche partitioning. This one looked like a gharial with long interlaced teeth. https://phys.org/news/2020-10-paleontologists-species-mosasaur.amp

Fun with Fakes- Moroccan Mosasaur
LabRatKing posted a topic in Is It Real? How to Recognize Fossil Fabrications
So after the oreodont fun, I’ve be checking my entire collection and the university collection. This is a known Mosasaur fake I got for 10$ and often use as a doorstop in my office. looks like I have some Chiplodocus and Chunkasaurus reckt instead of the usual camel and goat. Note the blue green fluorescence is dust from the synthetic carpet.

Found this thick bone piece in a new jersey cretaceous creek and wonder if its possible to maybe id since one side has a distinct rough texture while the other is flatter and striated, I would guess either large turtle, mosasaur, or dinosaur. My friend joked its a theropod maxilary skull fragment, but we all know around here that material seems close to impossible to come across haha. Interested to hear any other thoughts.
