  1. 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.....
  2. Green mill run mosasaur or crocodile?

    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!
  3. Skull growth of the mosasaur Tylosaurus is presented in this paper https://peerj.com/articles/10145/
  4. 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.
  5. Large NJ Cretaceous Bone

    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.
  6. Hi everyone! I saw these few mosasaur teeth online for pretty cheap and I'm wondering if they are real?
  7. *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.
  8. New Mosasaur Species

    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
  9. Dear Fellow Forum Members, On this day, the 4th of October in the year 2020, @itsronni @Masp @Trevor and @Jeffrey P ventured to a frequented late cretaceous stream in New Jersey. I first met up with Jeff and did some sifting before later locating itsronni and Masp further downstream. Finds came somewhat slowly after we first stopped to sift but after some time we gradually found more fossils. We stayed in one area for the majority of the day up until Jeff had to leave. After some deliberation, the remaining members and I walked a quarter mile upstream and then left shortly afterwards. It was a nice day to meet fellow forum members and also a nice day to collect fossils. Here are my finds, the others will post theirs when they can:
  10. A Gift from a Friend - Mosasaur?

    Welll....I got a lovely gift box in the mail from a friend who knew I liked fossils. I WAS SO NOT EXPECTING THIS IN THE MAIL! Imagine my excitement on finding a Green River fish, a nice big Megaladon and....pretty sure this is a Mosasaur tooth from Morocco? That's my best guess anyways. It kind of looks "staged" with the vert, but I don't care, it's really cool. So am I right in my attempt at ID as mosasaur? Since I haven't FOUND ONE YET I don't have any to compare! (And yes, I have been 'visuallizing" a mosasaur tooth and vert something fierce and the universe decided to play a trick on me and gave me one....but not one I FOUND. hahahhahahah).
  11. Mosasaur jaw

    Hello everybody, i received this mosasaur jaw (a dentary) from morocco, i don’t have any information on. The teeth are missing but i count 14 alveoli. According to the mosasaur thread of Jnoun 11, i think it’s maybe Mosasaurus beaugei or hoffmanni but i’m not sure for the identification, someone can help me to put a specie on this enigmatic dentary ?
  12. Here is a link to the story run by Utah State University: "Jaws of Death" LINK to original post about this discovery. Here is my story: My name is Gary Thompson, when I was a young boy our class was learning about fossils including some of the terrain and ground indicators for finding fossils. We took a field trip into the Escalante Canyon between Delta and Grand Junction Colorado. During this trip we were told that people have found dinosaur bones and petrified dinosaur dung in the canyon. During that trip I found a few interesting pieces. It was that experience that intrigued me and began my fascination for interesting rocks and fossils and started me hunting for them every chance I got. The year mom and I were about to move from Colorado to New Mexico I wanted to fossil hunt one more time before we left. I had been fishing in the Surface Creek many times in the past and was familiar with the terrain in that part of town. I asked my mom to drop me off out near the rodeo grounds where I thought I could do some good rock and fossil hunting. There was a road that goes up the side of the mesa were you could see layering exposed on the hills beside the road. Down at the bottom of the mesa where she dropped me off at Main and Cedar Mesa/Surface Creek rd there is an area that had loose dirt where I began to scan the area for anything that looked interesting. I noticed a darker dirt layer edging the top of the cliff like hill side. I climbed up towards the darker top edge and noticed some rust staining in the lighter soil layer right below the darker layering, which I had learned about in science class could be an indication of good fossil possibilities. In that lighter layer facing, I could see roundish oblong fossils with a segmented fern like fracturing pattern with a kind of caramel coloring. Some side views and some end views. I began investigating and digging out that area finding more shell fossils and the other fossils I later learned where called Baculites. After I got tired of that area I started walking up the road along the side of the mesa, scanning the edges for anything interesting. About half way up, I noticed an area a little bit back from the road with some mounding dirt that looked interesting. I walked back into that area and began inspected the ground for rocks and fossils. I was looking through the dirt and I happened to notice some scattered rock fragments on the ground that stood out to me. I have always had a knack for seeing differences and things that seem out of place. I began picking them up and inspecting them. After examining them more closely I noticed that they had a certain look, color and texture that indicated to me that it might be petrified wood or bone fossil. I continued to pick up and inspect these pieces when I found a little piece about 1 ½” wide and kind of oblong that had a more defined shape to it that looked like the end of a bone, looking at it as if it were sectioned, and you could see the circular bone outline of a marrow middle . I gathered up those pieces and then with my hands and a rock I started scraping the surface of the area to try to find more like those. As I scrapped and dug around I began to find what looked like long oval bones about an inch across and maybe 8-12 inches long, that kind of resembled rib bones. At that point I was certain it was bone fossil. I followed along that bone line clearing the dirt around the edges with my hands and a little stone. That section ran into what I could identify as large vertebrae about 6in across. It was then that I realized it was not a rib bone I had started out following but a part of a very large vertebrae. I excitedly began digging and clearing the dirt off the vertebrae section. In my child’s mind I was excitedly thinking I might have found a dinosaur. As I removed more dirt I exposed more vertebrae and it began to curve back into the mound of dirt a bit. I dug about 4 and a half feet of it out , leaving it in the ground but clearing the edges, revealing more of the vertebrae with the extending bones. At that point I realized that it was a very significant find I had made and that I needed to stop digging and report it. Because my mom and I were getting ready to move to Truth or Consequences, New Mexico that week, I did not want to leave it exposed and unprotected without telling someone about it. I felt that my science teacher Mr. Jones could help me contact the correct people so it could be protected, excavated and taken care of properly. I did gather up a few small samples, and I found some plastic garbage along the side of the road that I used to cover the bones that I had exposed. I then put dirt on top on the plastic to protect and hide my find. I walked home with my little bag of fossils and shared the exciting discovery with my mom Helen Louise Moore and showed her the samples I had collected. The next morning I brought the samples to Mr. Jones seeking his advise and help with the proper course of action. Mr. Jones was extremely curious about the samples I had found and what I describe to him. He kept the sample pieces and he asked me to take him to the site. I believe it was the same afternoon after school that Mr. Jones and I went back to the site in Mr. Jones’ vehicle. We parked near where I had found the shell fossils and walked all the way up to the large bone fossil I had begun to excavate and reburied previously. When we reached the site I began to carefully re-expose the bones I previously found. Mr. Jones could see there was something significant that I had discovered and excitedly began helping me pull the dirt back out from where I had previously dug and replaced it. When we had re-exposed the 4 1/2 feet of the fossil vertebrae that I had discovered and cleared previously, he confirm to me that it was a very important discovery. At that time we covered it back up with the plastic and dirt and Mr. Jones took me home. The next day I returned to school and I remember Mr. Jones was telling the class how I had found the bone fossils and he was talking about them to the class. My mom and I moved a few days after I discovered the bones and showed Mr. Jones my discovery. Before we left Cedaredge we had visited my grandparents to say goodbye and I told my grandmother about my exciting discovery. I left Cedaredge knowing that Mr. Jones verified my discovery and believing he would do the right things with my discovered bones and that they would not be destroyed. I was a kid at the time so I did not know how to follow up with the teacher or the project. Sometime later I received an envelope from my grandmother, Helen Moore that contained a Delta County Independence newspaper that had an article written by Muriel Marshall. She had written the story about the activity at the site and that I had discovered the fossil. It was very satisfying to see my name in the article and to know Mr. Jones had spoken with her verifying my find. In this article I also learned that my discovery was a really significant and exciting find and Dr. Jim Jensen (dinosaur Jim) from BYU was excavating the site and that he had not yet been able to identify it but thought it could be a new species of some kind. I was happy to learn that my discovery was so significant and relieved that my discovery had been properly reported by Mr. Jones to Paleontologist ‘Dinosaur Jim’ of BYU and that it was being properly cared for. But, I was also sad that I could not be there to be a part of it. The article also told of the school kids taking a field trip to the dig. It had talked about the young Scheetz brothers who had been helping Dinosaur Jim at a previous dig site, and had come to help him and Mr. Jones at the Cedaredge site as well. Upon detailed research of the mosasaur’s skeleton and a phylogenetic analysis, Joshua Lively PhD determined the BYU specimen is not closely related to other species of the genus Prognathodon and needed to be renamed. He reclassified the mosasaur as Gnathomortis stadtmani, meaning "Jaws of Death", and reports his findings in the most recent issue of the Journal of Vertebrate Paleontology.
  13. North Sulphur River 2008

    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.
  14. North Sulphur River 9-25-20

    Here are some pictures from my latest trip to the NSR. Nothing special this trip but I was wondering what the last two pictures are of. Seems like a more recent fossil possible a tooth of a mammal?
