  1. Lance formation tooth

    I found this tooth in some matrix from the Lance formation from Wyoming. It reminds me a little of a croc tooth, but could it be something else. The division markers are 1mm. Thanks
  2. Hello everybody So this fossil here bothers me for some time now because I'm still not sure what to make of it. I'm especially asking for the roots in the jaw and if they are a composite. Also this one tooth growing out of the root of the root looks odd to me. Is this a genuine fossil or are these roots / tooth put in the jaw? I'm used to these fake teeth put on jaws as a composite form Morocco but with this one I'm still not sure what am I looking at. On one side you can actually see the root in the jaw. Would something like this be fabricated as well? And is the ID correct? It's described as a partial maxillary of an Elosuchus sp. from the Ifezouane Formation, KemKem from Taouz/Morocco. No word about any restoration/fabrication or what so ever. Size is 3.48 in (8,84 cm).
  3. Crocodilian tooth

    From the album Macro Florida Fossils

  4. Fossil Armor

    From the album Macro Florida Fossils

    I think this is crocodilian
  5. I watched a show on PBS last night, "When Whales Walked: Journeys in Deep Time." I just happened to notice it on the guide about 45 minutes before it was on. It is actually about more than the evolution of whales, the group having four-footed Early Eocene ancestors. There is a long segment roughly twenty minutes long each on crocodilians, birds, whales, and elephants. I thought it was a good show overall with interviews of researchers I know from their technical articles ( Hans-Dieter Sues, Philip Gingerich, Emmanel Gheerbrant, Christian de Muizon). However, each segment was also a little light on content for the topic and one was especially unclear. The one on birds made it appear that Deinonychus was an ancestor of later birds. They should have showed a chart showing when it lived in the Cretaceous with Archaeopteryx and the Liaoning birds millions of years before. There was a quick view of a family tree that seemed to illustrate that but it went by in a second or two. The segment on whales showed a lot of footage of modern whales and some great background on the "first whale," Pakicetus, but it didn't show any of the whales described in the past twenty years. It just mentioned that there had been recent discoveries. I thought there should have been at least a quick look at Ambulocetus and a few of the increasingly more marine-adapted forms that lived before Basilosaurus. They pretty much jumped from Pakicetus to Basilosaurus to the divergence of toothed and baleen whales. I think they could have spent the two hours just on the whales just as the title of the show led me to believe. I liked the segment on elephants because just as I was expecting the show to skip the earliest known members of the group, they go to Morocco and then talk to Emmanuel Gheerbrant who described Phosphatherium, the first probiscidean, which is known from the same early Eocene phosphate layer as a lot of the shark teeth we see at shows are from. Other extinct forms were descussed as well. Here's a link that takes to an online notice and website: https://www.pbs.org/show/when-whales-walked-journeys-deep-time/ Jess
  6. Croc or spinosaurid teeth? Kem kem

    Hi! Are these teeth croc or spino teeth? , The curvature and the robustness makes me wonder if they could be croc teeth. Both are from Kem Kem Tooth 1:
  7. Croc kem kem tooth

    Hi! I have a rather big croc tooth from kem kem and I was wondering if it could be a Elosuchus tooth because of its size? or should I just label it as Croc indet?
  8. Florida Creek Finds

    I hit my favorite creek spot again and I found a lot more new things than I usually do. I found these teeth that looked like broken shark teeth tips but I realized were to flat to be shark teeth. Sorry the seconds blurry. But they seem to be sharp on one edge and round on the other. And yes I know i have a few croc teeth mixed in.
  9. Moroccan “Croc” Repair

    I got a call last week to pick up a croc skull for repair. I excitedly went to get said skull only to find a rather poorly done fake for me to repair. I said, “you know this is fake right?” The response was “uh, yah. Go ahead and fix it.” So, I have gone from fossil preparation to “art” restoration today. This is what I had to work with. Seems easy enough right? Wrong! The hard part about fixing a fake is understanding how the fake was built in the first place. This is made of random bone fragments cemented into a “matrix” with random croc teeth cemented in place. They didn’t even try to make it look real, clean up the cement, or put teeth in the right place. So, I had to figure out where these things are “supposed to go”. After the repairs were done, I scraped off some of the “matrix” and made a paste with glue to fill the cracks...
  10. Hunting in cretacous

    Hi we the current good weather I managed to spend one day in fossil hunting I searched in upper cretaceous co.tinental deposits with the hope to find some dino remains Undortunately I found all except that : Hybodontidae fresh water shark Allodaposuchus crocodile Solemys turtle scute Dino tendon :
  11. Hi, I have what is described to me as a turtle claw from the Moroccan Phosphates. That's all the info I was given unfortunately. It has a curve as seen from the top view. It measures 44mm long. First up, is this a turtle claw? Second, is it possible to ID its family or species? Third, what could the age be? I am guessing 70.6 - 55 million years old. Fourth, can I narrow down the locality? Thank you for your help.
  12. What kind of tooth is this?

    I found a tooth here online and it claims to be a Raptor tooth from Hell Creek. It has a classic Kem Kem color and kinda looks like a croc tooth?
  13. I had a great day fossil hunting yesterday! I found my first crocodile vert! Which are even rarer than ichthyosaur verts on the yorkshire coast! Then i found articulated 4 and a half icthyosaur verts! With 3 neurals, will polish up great! It had been a very slow month for finds then i have a fantastic day like this
  14. Is there any fellow fossil addict here that could help me to: Aligator skin plate (thats called a scute, right? ) Larger Ray dental plate No need for mint/ spectacular pieces, recognisable will do. Got some trilobite bits & bobs for trade Cheers Pat
  15. Hello everyone, I am in desperate need of help with a huge debate I have been having with a friend over fossils preserved in ironstone concretions. From some of what I had read to some advice from other members I it possible to find vertebrate bone among shells and other mollusks preserved in an ironstone concretion. Whether it leaves a trace of the organism, morphs the organic material into the structure of the iron concretion through the decomposition with preserving, or whatever else it may be it seems to be possible. So recently I have hunted a place known to have recorded marine cretaceous shell and other mollusk found in ironstone concretion as well as cretaceous plants in shale, it seems like not to vast of enough study has been done there only from what I know, but since no vertebrate material had yet been discovered there though there can maybe be the possibility. I found these two particularly distinct pieces in iron concretions that exactly mimic the scute structure of soft shell turtle and croc in my opinion, I know how iron concretions are famous for leaving psuedofossils and such but these two pieces look way to exact and since its possible for shells and mollusks to preserve why not scutes? So I am here looking to end this debate, I'm looking for your opinion, can these be labeled as fossils, traces, etc? Or are these among some of the world's best iron concretions and nothing more. Your input especially if you are very experience in this subject would be tremendously appreciated.
  16. Some more Moroccan fossil listings. Wondering if any are worth looking into. Trying to properly ID. #1 Partial unidentified dino limb bone or Croc?
  17. Matoaka beach, Choptank FM, Lower Miocene Before I start out, may I just say Matoaka is a beach not known for its shark teeth. Most fossil hunters go there for invertebrates, Which are incredibly abundant. Shark teeth are usually small, a bit worn, and take lots of work to find. The old saying (that I just invented) goes “If you want a chance at a meg, go to brownies. If you want lots of sharks teeth, go to Purse. If you want a snail, go to Matoaka. If you want to be told you can’t walk under a cliff go to Calvert Cliffs state park” I decided that I was going to walk as far as I felt I could and still get back with daylight. For the first stretch I found literally nothing of interest and the nagging fear that I was going home empty handed kicked in. I had set my mind to “Ecphora mode,” because sharks teeth were not gonna be found. The tide was lower than last time, so I got to have a good look at a new slide that looked really promising. I was right, it was littered with Ecphora. Unfortunately, almost none were extractable or worth the extraction. This one was a real heart breaker, big for me but sliced in half and in really loose clay.
  18. Mosasaur or croc tooth - NJ Cretaceous

    Hello everyone! I hoping to get some clarification to help differentiate Cretaceous crocodile teeth from Mosasaur teeth. These two were found in the New Jersey Cretaceous. The first one is a shade under 1/2 an inch. It is conical and doesn't appear to have any cutting edges (but they could be worn off). I was leaning towards Mosasaur tooth on the second one because of the size of 8/10ths' of an inch, but it is slightly more slender than my other Mosasaur teeth, very conical and the root looked a bit different. It appears to have one very weak cutting edge but I'm not positive. It was pointed out to me that crocodile teeth roots tend to have concentric rings so I was wondering what everyone thought regarding these guys. Thanks! @Plax @josephstrizhak
  19. Calvert Cliff Croc bone?

    Looking for confirmation here, is this a croc skull bone or osteoderm? I was putting all my Brownies beach finds into one box and I saw it and immediately picked it up, I don’t know how I missed it! Croc material is pretty uncommon on the cliffs, so if even this one inch bit is croc I’d be super happy!
  20. Crocodile tooth or plesiosaur

    This tooth came from a NC quarry known for both Eocene and Cretaceous fossils. My first inclination was a croc tooth. Is it possibly plesiosaur? Seems like the shape could fit either.
  21. The Green River Formation is one of the most well-known fossil sites in the world, occupying present-day Colorado, Utah and Wyoming. This Lagerstätte has been noted for its well-preserved fish fossils, as well as numerous invertebrates, plants, and sometimes even reptiles and birds. Green River fossils are Eocene-aged, at 53.5 to 48.5 million years old. Thankfully, not only are Green River fossils attractive, they also remain affordable to the casual collector. Allow me to present my humble collection. Crocodile tooth Borealosuchus sp. Southwest Wyoming Water bird tracks (possibly sandpipers or plovers) Presbyorniformipes feduccii Vernal, Utah Bird feather Aves indet. Southwest Wyoming Crane flies & Mosquitoes Pronophlebia rediviva & Culex sp. Parachute Creek Member; Douglas Pass, Colorado
  22. Cretaceous Tooth

    Need help on this one please. Its pretty worn - is it a croc or maybe a mosaur? It is really flat. Thanks. Sorry pics aren't the best.
  23. Another One I'm Not Sure Of...

    I've got this one fossil that I'm not quite sure how to classify it... It\s supposed to be a fossil Pterosaur tooth found in Kem Kem Beds of Morocco.... 1.75" long... However, it doesn't match any of my Pterosaur teeth... Or Crocodile, or Spinosaurus... Is it some sort of fish tooth? Thanks in advance, more pics if needed...
  24. So I was browsing our favourite auction site, and I came across these interesting specimens. The seller claims these all belong to the same individual, while at the same time, strangely, they are selling each bone separately. And while these bones are definitely real Kem Kem bones, I'm posting it in this forum because there is reason to believe the information that these belong to the same animal is suspect. All of these are sold as being from one individual Spinosaurus. This first one is definitely a Spinosaurid cervical vertebra. a fairly nice one. But the rugose triangular area on underside shows that this is in fact from a Sigilmassasaurus, one of the Spinosaurids from Morocco. From the length of the vertebra this can be placed somewhere in the back of the neck of the animal. Next specimen is also a Spinosaurid cervical vertebra. Though due to damage this one is harder to identify as Sigilmassasaurus. Again due to the shortness this seems to be a cervical vertebra from somewhere back in the neck. The dorsal spine though worn, seems to be not that big. So this might point towards it being Sigilmassasaurus as well. So seems fairly plausible if the seller says these belong to the same individual right? Now here comes the problem. This third specimen is listed as belonging to the same individual. But this is clearly a cervical vertebra from a type of crocodile. Since it's nice and complete we can see which way is the front and which is back. The front of the centrum looks to be concave, while the back of the centrum here is convex. This is typical of some crocodiles. But on Spinosaurids it's the other way around, with the front of the centrum being convex and the back is concave. So with that this specimen casts doubt on the whole claim that some of these specimens belong to the same animal. Which is too bad 'cause the fossils seem pretty nice. There were some other specimens as well. But these three were clearly identifiable.
