  1. Mosasaurus Fossil ID

    Was curious of what was inside of the matrix that my mosasaurus tooth was in, I'm mostly curious on what the fossil on number 6, 7 & 8 is. I'm guessing that it is a root of a mosasaurus tooth?
  2. Mosasaur tooth

    I got this tooth as a freebie when I bought some fossils a while ago. I know it's a mosasaur tooth of some description and my guess would be Prognathodon sp. based on how common they are, but I'd like confirmation (if possible) for my own peace of mind. I know it's not easy ID'ing based on tooth crowns, but hope springs eternal. The tooth is about 3.5 cm long.
  3. What do you guys think about this Mosasaur tooth, with a emerging replacement tooth? Composite or not? I have bought many times from the reseller and no problems, he guarantees the authenticity, but with this tooth I doubt..
  4. Hi everyone. So I've an old HS fb friend who found this doing tractor mowing in an area called Sand Knob. Ky is littered with these knobs, similar to a mountain range. My question is, could this possibly be an 85 million yr old fossil from the Cretaceous Period? (The last time oceans were in Western ky) It appears to be a whale vertebrae to me and others but they insist it was "dropped" or "planted". This 100% was not randomly buried by a trickster in a remote area of Casey Co. This sandy Knob region could be the banks of the Mississippian range. They are actually. Similar to how beached whales wash up on the beach, this creature, with a rise in sea levels, could very well have been deposited here. It's approximately 200mls away to the western region that known Cretaceous fossils have been found. Could this change the map in terms of Period location? Do the sandy knobs represent the banks of a past, epic event in sea levels rising? What catastrophic event would send sea levels 200mls East? Meteor? Ice caps melting? Mosasaur was known to crawl to land to give birth could this have been the leftovers of a takeaway dinner? Lol
  5. Ahoi. Another marine tetrapod. To be perfectly clear, This is a commercially bought Model which I changed to my ideas.Like my marine sloth and most of my dino- and other saurian ,models, but not my whales. I ordered the model from geoworld because some of the line had been quite nice. When I first saw it I didn´t think I could make something for my collection out of it. Tried it anyway. Because of the size in my chosen scale of 1/20 I decided to model it on Platecarpus, although I don´t claim to be accurate to even genus level. It´s just the medium sized Mosasaur to go with my whales and other seacritters. The flippers may need further detailwork. But for now I am content with the result. The base is a recent tuna vert by the way. Aloha!
  6. I saw this at a Fossil convention in Vienna it was priced around 230 euros that's about 250$. Is it real?
  7. Welcome to my first Fossil ID Post! I bought this fossil at a Market in Johannesburg. The seller claims it to be a juvenile Mosasaur. The sediment layer seems to be derived from seabed but I am no expert. Seller claims to have retrieved the specimen from Morocco. Kingdom: Animalia Phylum: Chordata Class: Reptilia Order: Squamata Clade: Platynota
  8. Last week i was at the natural history museum in maastricht,netherlands,there was a fantastic mosasaurus' skeleton that impressed me

  10. New Jersey Mosasaur tooth ID help

    Greetings! I recently found this partial (what I believe to be) Mosasaur tooth and the texture of the enamel isn't typical of the Mosasaur I have found. I was wondering if this is consistent with any particular species of Mosasaur or if it's just a different type of preservation than I am used to. It was found in the Monmouth County NJ Cretaceous and the bottom part of the tooth is broken. Thanks in advance for your help! -Frank .6 inch Two cutting edges
  11. Hi! I'm looking if anybody wants to trade mosasaurus or croc,gator teeth with me! I'm offering Miocene lake shells and plant parts which i've found in Marl stone mine in Popovac,they're 14m years old.If anybody is interested let me know
  12. North Sulphur river bones

    Went to North Sulphur river yesterday. Found couple bone fragments, not sure if there is enough for a positive ID, but hopefully someone will recognize them. Thanks in advance. 1. rib? are those teeth marks? 2. ? 3. Bony fish centrum? 4. ? 5. ? 6. Coral?
  13. Mosasaurus tooth?

    Hi all, Am I on the right track here? Is this a Mosasaurus tooth? It was found in Iron Ore Creek in Grayson Co. Texas. Upper cretaceous, Austin chalk runs throughout this area of Grayson co. so believe it's within the same strata as Post oak creek in Sherman. About 15/16" long and 3/8" wide.
  14. Maastrichtian Mosasaurus

    Hello everyone, I mounted this skull, but I'm not sure you have identified the species. I think it's Mosasaurus prognathodon, but I see a strong resemblance Eremiasaurus Heterodontus. What do you think? thank you Snen

  18. Hi all I just wanted to share a project that Ebrocklds and I finished up and shipped over to Europe a few weeks ago. It is a fantastic 14 foot Halisaurus sp? from Morocco. It is quite different anatomically form Halisaurus arambourgi in that is has several strange skull proportions and features, as well as a few skeletal anomalies. Its skull was 100% complete, which allowed us to do many comparisons. As you can see from the pictures, the parietal eye is raised nearly 1/2 inch above the rest of the skull. The Maxillary on each side at the nasal opening has a raised, cylindrical, ridge. The post-orbital/frontal are very thin and flattened and sit at a very strange angle that was not altered by compression. All-in-all, it is a very unique and interesting animal. (Yes those are my adorable daughters) Enjoy.

  25. How long is mosasaurus?

    Hello, I'm a new member to this forum and a year 7 student, and I'm wondering how long mosasaurus is? The sources I've found on the internet and in books vary dramatically (10m and 24m!). I'm fairly sure that the actual length is in-between these lengths but I'm not certain! Also, related to this problem, I've found it difficult to locate an up to date book/site that shows accurate and updated portrayals of dino's. Any help? greatly appreciated, Aaron UPDATE: Thank you all for these articles! A lot of it went over my head but I now the actual size now, 6 metres! Thanks SOOOOOOO much!
