  1. Basement recovery part 2 Reptile Replicas?

    Part 2 of my Fathers basement I have 2 crocodile skulls and one turtle. I believe they are Replicas? but the teeth on the crocodile are Fossils? once again I believe these are out of Morocco in the 70s or 80s? Thank you
  2. Marine reptile tooth ID Lyme Regis

    Hi all, Bought this tooth online a while back. It was sold to me as "Ichthyosaurus platyodon" (which I understand to mean Temnodontosaurus platyodon) from Lyme Regis. Likely found by the seller themselves, as I know they occasionally collect fossils there. However, for the following reasons, I'm not sure about this attribution: Overall, the tooth doesn't look like your typical ichthyosaur tooth to me: It has more of an oval rather than round cross-section It's labolingually flattened Messial and distal carinae run the full length of the crown and divide the tooth into labial and lingual parts While fine striations can be seen on one side of the tooth (presumably the lingual side), the other side (which would be the labial) seems entirely smooth - though some traces of rare striations can be seen on the photographs The striations are much more similar to those of crocodile or pliosaur teeth than to the plicidentine condition so typical of ichthyosaurs The horizontal banding on the tooth surface is unfamiliar to me with respect to most marine reptile teeth I have seen, but occurs much more frequently on crocodile teeth of various species I also bought another tooth with the same attribution from the seller, more or less around the same time. This one has no striations whatsoever, has a more rounded base, is less flattened and has a more rounded tip. It also has carinae. I therefore reclassified it as a probable Goniopholis sp. crocodile tooth. Now I know that not having the root makes it more difficult to identify this particular specimen, but I was hoping someone on this forum might be able to help me, as currently it goes without label. I've considered crocodile, plesiosaur and even pliosaur, but all of these have some reservations that prevent final classification. For one, none of these groups have teeth that are typically flattened like this, nor do plesiosaurs (sensu lato, thus including pliosaurs) have carinae. Crocodiles, then again, would either have or not have striations all around the tooth. And what to make of the banding: is this just preservational, or does it reflect the internal structure of the tooth - i.e. outcome of the tooth's ontological growth? Tooth measures 18 mm and is missing the tip. Thanks in advance for your help!
  3. Crocodile Egg or Sea Urchin?

    During a trip to Egypt I found this potential fossil near the city of Aswan between the banks of the Nile River and Sahara Desert. I had thought it might have been a meteor and the sand fused around the meteor due to the Intense heat. But, I tested it with a magnet but there was absolutely no attraction. Therefore, I thought it might be a fossil given that I read about many fossils being discovered in the Sahara and the composition does appear to be any rock or stone that I've ever encountered. I assumed crocodile due to the spiky and bumpy texture, along with the historic prevalence of crocodiles in that region. What do you think this is? Thanks!
  4. Went on a kayak trip on the Potomac for Father's Day with one of my kids. We spent a couple of hours around some paleocene spots. I found yet another lucky otodus right off the bat (sadly, one cusp missing). Between the two of us we then picked up a bunch of smaller teeth and a fair number of ray plates. We also got 3 croc teeth, including a nice fat one I found on my very last pass. I think we also got a small coprolite in there, but not 100% on that, and a chunk of turtle shell. All-in-all, not a half bad Father's Day trip!
  5. Hello! I recently saw this crocodile skull fossil at a rock shop. I understand that there are many fake croc fossils from Morocco, but I'm having trouble identifying this one. I don't see any obvious signs that are present with bad fakes, but I'm a real novice at fossil identification. Are there any red flags I'm missing? For reference, the skull is approximately 11" x 4".
  6. Sarcosuchus or bust??

    Hi I purchased this tooth from a local shop and was just wondering if it is from a sarcosuchus either S. Imperator or S. Hartti? Is it even possible to tell species from a single tooth? They listed it as coming from Morocco and being from the Cretaceous ~100MYA. However the slip also mentions Elosuchus ~70MYA. My knowledge about prehistoric crocodiles is very limited. I’d be happy to just have a fossilised croc tooth as it would be my first and I didn’t pay heaps.
  7. Mosasaur or Thoracosaurus

    Hello all, Recently my girlfriend and I went up to Ramanessin in New Jersey for a fossil hunt. After a while I came across this tooth! Upon trying to identify it I couldn't exactly figure out whether it was a crocodile (Thoracosaurus) or a mosasaur from the area. The tooth is more ovular in cross section. If more pictures are needed I can send them. Im leaning more towards Thoracosaurus. Thanks!
  8. Kem Kem croc jaw fragments ID

    I've got five jaw fragments from the Kem Kem of which I think they are from crocodilians. Any ideas as to what genus or species these belong would be appriciated. 1. No idea what this jaw is from, but my best guess is some crocodilian. 2. I also don't know what this is but also probably some crocodilian. 3. This one has a hard layer of sediment covering it and it's missing the underside of the jaw. It looks a bit like the dented part of a Spinosaurus dentary but it's more likely also crocodilian. 4. Definitely crocodilian, has a typical croc texture (lots of dents). To me it looks like a right jugal with a part of the maxilla. 5. Also some crocodilian, resembles an Elosuchus jaw but it's pretty small so maybe a juvenile or some other croc. Have fun ID'ing!
  9. Hello, I'm new on this forum and I've got a fossil of which I don't know what it is so I thought I'd ask. It's from the Kem Kem. I don't know which formation but it comes from Taouz. Only one side has been preparated. I haven't preparated the other side because it's a pretty thin bone and I'm afraid it might break. It seems like it has broken and been repaired before. Also, there's an Onchopristis tooth attached to it. I think it might be a skull fragment because of it's odd shape. Specifically I think it might be some theropod's left postorbital of which only the inside has been preparated. But there aren't a lot of Kem Kem skulls to compare it to. So it might be something entirely else. Any ideas as to what it could be would be highly appreciated. Top view Front view
  10. Kem Kem Mixed bones

    Hello, I know assorted bones can be difficult, but I'm wondering if anyone can recognise any of these mixed bones? Labelled as Kem Kem Dinosaur, possibly Spinosaurus. Anyone has any idea. Whether bone, kem kem, dinosaur or spino, that would be much appreciated. Cheers
  11. Croc or dino vert?

    I saw this pair for sale, before buying, I figured I'd check if they are dino as listed rather than crocodile. If anyone could take a look, that would be great. Described as two caudal verts, larger one repaired. From Kem Kem Basin. They are small, the cube pictured is 1cm.
  12. Here is the link to an open source book published by the Calvert Marine Museum. Skeletal Anatomy of Alligator and Comparison with Thecachampsa, by George F. Klein. 2016, 75 pp. Annotated photographic atlas. (Print copy is also available for purchase.) During the Miocene epoch, large predatory crocodilians lived in a warmer southern Maryland. Their fossilized remains are now found along Calvert Cliffs. By providing a detailed annotated photographic atlas of the skeleton of the living Alligator, this work will help identify the fossilized bony remains of Thecachampsa - the marine crocodilian that shared its habitat with the likes of megalodon. http://www.calvertmarinemuseum.com/276/CMM-Publications. Also, here's the link to the museum's fossil club newsletter archive: http://calvertmarinemuseum.com/204/The-Ecphora-Newsletter. I am not affiliated with this institution, but am simply sharing some links I have on file. Enjoy.
  13. I've always been fascinated by the Cretaceous sea and its myriad of terrifying carnivores, many that would've made Jaws look meek. After watching BBC's Sea Monsters, I made it my goal to compile a box of sea monster fossils. I started this journey 10 years ago, and finally completed the box recently. Allow me to present my Predators of the Cretaceous Sea collection, and take you on a journey to the most dangerous sea of all times. The box measures 20.25 inches long. Inside are 24 unique predator fossils. I will introduce them from left to right, top to bottom: Rhombodus binkhorsti Age: 70.6 - 66 mya | late Cretaceous Formation: Severn Formation Locality: Bowie, Maryland, USA Size: 1 meters Diet: Molluscs and crustaceans art by Nobu Tamura --------------- Polyptychodon interruptus Age: 105.3 - 94.3 mya | Cretaceous Formation: Stoilensky Quarry stratigraphic unit Locality: Stary-Oskol, Belgorod Oblast, Russia Size: Maybe 7 meters (This is a tooth taxon so size is not confirmed) Diet: Anything it could catch Note: If you consider Polytychodon a nomen dubium, then this is a Pliosauridae indet. art by Mark Witton ----------------- Prognathodon giganteus Age: 70.6 - 66 mya | late Cretaceous Formation: Ouled Abdoun Basin Locality: Khouribga Phosphate Deposits, Morocco Size: 10-14 meters Diet: Everything art by SYSTEM(ZBrushCentral) --------------- Coloborhynchinae indet. Age: 99.7 - 94.3 mya | late Cretaceous Formation: Kem Kem Beds Locality: Southeast Morocco Size: 7 meters (high estimate) Diet: Fish and cephalopods
  14. With the current pandemic I decided now was as good of a time as any to get some matrix from the Aguja Formation with the help of PaleoTex! This turned out to be a great decision as I was extremely lucky, finding about basically everything I wanted to, and more in only 5 pounds of matrix! I'll be sure to post pictures but I got numerous amia and gar teeth, along with atleast 36 gar scales. Tons of Crocodile teeth including a large Deinosuchus tooth. Several shark teeth and a partial hybodus spine, also several brackish water pycnodontid teeth and tooth pallets. 4 fish or salamander jaws with teeth. Regarding dinosaur teeth I got 17 Hadrosaur teeth, including 2 partially rooted. A partial Ankylosaurus tooth. 4 Therapod teeth including a perfect Saurornitholestes tooth and a Premax. My favorite find however was the Paronychodon tooth I found! I'll be posting that picture first! Highly recommend this matrix, but I was also told that most people don't find all this stuff, so keep that in mind aswell. Stay safe! Happy hunting! (ID's for these specimens done by lab manager)
  15. UK Marine Reptile Teeth

    Hello all, I've had two teeth in my collection for many years now. I've recently moved and lost the supplied ID labels that came with them. I've taken this as a nice opportunity to see what others may think they are. I believe if memory serves me right the large tooth (Tooth A in photos) was labeled as a Simolestes. Then the smaller tooth tip (Tooth B in photos) labeled as Liopleurodon. I know both were found in the Wicklesham pit in Faringdon, Oxfordshire, UK. Upon some research, I found an article from 2014 with a Dakosaurus tooth discovered to be the largest in the UK at the time. This tooth bears some resemblance to tooth A but I'm unsure. I've attached a link to the article below. Tooth B has been worn down but still presents with grooves in the enamel. I have also labeled each photo to allow for easier identification when talking about it (Hope this helps!). Im excited to hear what others think. Thanks for reading Link to articles on Dakosaurus- http://www.sci-news.com/paleontology/science-tooth-fossil-dakosaurus-maximus-01954.html
  16. Mystery mammal tooth?

    Found this tooth the other day at a miocene exposure along the Potomac River in Virginia (Westmoreland State Park). Hoping someone can help me identify Thanks in advance - Mitch
  17. Spinosaur tooth or crocodile tooth?

    I have this tooth from the KemKem basin in my collection. I have always assumed it is Spinosaur but having looked at it again I am starting to wonder if it is crocodile. Can anyone confirm the identification? Thanks, Daniel
  18. Hi there i continue to maintain my very very amateur status but I've been trying to read the different threads on here regarding spinosaurus jaw and what I gathered so far is pitting is reflective of croc jaw and if it only has a single socket or also makes it difficult to determine if its spino or croc. I found this one on our favorite auction site and wanted to get your opinion
  19. Found this tooth in Ramanessin in Holmdel, NJ. It is about 1.4" long, and it is missing about 1/4 of the top. There are striations along the entire length on all sides, and the top of the tooth has a very faint slightly raised line, but not to the extent of the Mosasaur teeth that I've found previously, so I'm leaning towards it being a Crocodile tooth, or possibly some other species. I figured I would ask for some opinions, since I am far from an expert. Thanks in advance for any input.
  20. Kem Kem Vertebrae ID (Croc/Dino?)

    Looking for a little help identifying some small Kem Kem vertebrae. I have some ideas as to what they might be, but I'm sure I'll be corrected. Hopefully the answers will prove useful to anyone else trying to identify Kem Kem verts too! So here's what I think these are: Vert 1: Small theropod, possibly a juvenile spino? (or maybe crocodile) Vert 2: Crocodile Vert 3: Crocodile? Vert 4: Theropod dinosaur Vert 5: Theropod dinosaur (looked a little similar to an Abelisaur vertebra I've come across on the forum before)
  21. Found this odd fossil on Myrtle Beach 2-18-2020. Never found one like this. Personal opinion it resembles a crocodile tooth that broke, and point recessed into the larger portion. However it is very solid, and there seem to be no seams to confirm this (and it was a wild guess on my part anyway). Hopefully one of you has a more educated opinion. I'd love to hear from you if so. Thanks for looking and happy hunting.
  22. Aquia Formation bone fragment

    Hi all, I found this chunk of bone at Purse State Park this November. It is from the Aquia Formation, which is of Paleocene Age. I was wondering if it could be identified to either crocodile or turtle, considering that these are the only two bony vertebrates that exist in large amounts in this formation. Or, of course, it could be nailed down to chunkosaurus status considering that it is relatively worn and isn’t very large. Thanks in advance!
  23. Croc or Turtle Ungual?

    Curious if anyone actually knows the difference between croc or turtle/tortoise unguals? Are there any diagnostic features? Have this ungual that we've always been in-between as to what it is:
  24. Hello, this is my first post on the forum so firstly I apologise if I have done anything wrong. I brought these teeth a number of years ago and have only just got round to sorting them out. The first one was listed as Jurassic crocodile tooth and the second as Jurassic Plesiosaur tooth, they both come from the Oxford clay around Peterborough. I would really like to put a species name to these teeth if possible so any help would be greatly appreciated. My initial thoughts were Metriorhynchus for the crocodile tooth and Cryptoclidus for the Plesiosaur but I am a complete amateur and would love some help from professionals. Finding information online about the Oxford clay seems to be very difficult. Thanks in advance for your help.
