  2. I noticed the fossils of more 'modern' reptiles are not commonly shown/displayed (partly because I think they are fairly common in the U.S. and not viewed as too spectacular), so I thought we might do so here. I'd love to see your croc/alligator and turtle material, especially from various locations!
  3. Thinking tapir tibia but not sure

    Found in Florida river. Previously found tapir in the area and was wondering if this was tapir tibia.
  4. Pleistocene gator and deer fossil ? Brunswick, GA

    Hi Guys, This would be the first alligator tooth that I've run across .. but it is really the deer skull fragment that I'm curious about ? I'm calling it that because that is my assumption seeing what I think is the interior of the skull with the brain impression and the lower part of the antler base ? These deposits are dredge spoil piles and have a mish-mash literally of marine and terrestrial fossils. I tossed in an image of the G. cuvier for kicks because the preservation is pretty good coming from a land site. If you need additional images let me know. For Kicks. Cheers, Brett
  5. Alligator Tooth?

    This reminds me of an alligator tooth? Seems a bit large...
  6. Alligator teeth fossil or just a rock

    I'm not even sure if this is a fossil, looks like a baby alligators teeth. I do know that the teeth should have a different color than the rock. This was found in Venice Florida
  7. Non Shark Teeth from Peace River

    I'm relatively new at fossil hunting in the Peace River but I found a few nuggets that I am not able to identify so asking for expert schooling here. I assume the first is a long tooth but broken at both ends. The second (3-4" marks) is much smoother and has a twist to it. The 3rd at 5" is just a conical tip of something. The two at 6 & 7 appear to be vertebra of some type but I don't know what, these were found almost a mile apart. The pieces at 8" and 9" are unknown to me, at first I thought it was a curious formation but now I've seen 4 or more of these so I started saving them. I don't know if they are fish tooth or a "claw" or just funny rocks? The final question is an oddball that seemed to "unusual" to be just a "rock" but other than describing it as "brain like" I don't know what it would be? Fish ballast? Thanks in advance!

  8. I've sorted two general groups of specimens as shown in images looks like some dolphin and alligator teeth to me, and then some things that don't- specimen A is a dome shaped hemisphere G is flatter and could be enamel H also looks like enamel anyway appreciate any comments
  9. Composite skeletone

    Hello all, I already posted this topic in Paleo Re-creations, but nobody answered there. I want to make a composite skeleton from an extinct animal, but I don't know witch species I take best. I already tought about Oreodont, cave bear, bison... Do you guys know an animal whose it is possible to collect all the bones (skull is not necassary, but I would love a real skull) Keichousaur is not a good example, because I want have the fun for searching, buying and making a composite. It think mammals are the only option, because reptiles are expensive and difficult to collect all the bones, maybe alligator is possible? What do you guys think about it? Greetings
  10. I've written trip reports before about volunteering with the Florida Museum of Natural History (FLMNH) at their various dig sites in Florida. The currently (very) active site is called Montbrook for a small town that used to be in the area (but is no more). Here are a few links from FLMNH which provide some contextual information about the site: https://www.flmnh.ufl.edu/museum-voices/montbrook/ https://www.flmnh.ufl.edu/florida-vertebrate-fossils/sites/mont/ https://www.flmnh.ufl.edu/museum-voices/montbrook/2016/09/07/why-montbrook/ The site has yielded an impressive number of specimens and is very important scientifically as it provides the best view of Florida fauna from the late Hemphillian (Hh4) North American Land Mammal Age (NALMA) from approximately 5.5-5.0 mya. The other significant locality for this age is the Palmetto Fauna a couple hundred miles south of the Montbrook site. More info here for those interested in the stratigraphy: https://www.flmnh.ufl.edu/florida-vertebrate-fossils/land-mammal-ages/hemphillian/ https://www.flmnh.ufl.edu/florida-vertebrate-fossils/sites/palmetto-fauna/ Here is a link to my Montbrook posting from 2016 showing the couple of times I managed to get out there--the last time with TFF members Daniel @calhounensis and John-Michael @Brown Bear: http://www.thefossilforum.com/index.php?/topic/63056-volunteer-dig-with-the-flmnh/ Now, enough of the links and time for a few pictures! The Montbrook site has changed quite a bit over the last year since I've been able to get out there. We had plans to return to Montbrook last October but Hurricane Matthew was an uninvited guest to Florida that week and the dig site was tarped down and the dig cancelled. Thankfully, the hurricane left my house untouched (didn't really even get rain or wind of note) and didn't mess-up the Montbrook site but we did miss an opportunity for one last trip to Montbrook in 2016. When we returned in February 2017 it took some time to get my bearings. The deeper pit to the east where several gomphothere skulls, tusks and long bones had been removed did not weather the rainy season well. This section has been backfilled with about 5 feet of sand and clay from the higher levels during the summer rain storms. For now they will concentrate digging on the main pit to the west and hope to get back to the lower "elephant" layer some time in the future--though the prep work to remove the overburden and get back to the original level will be significant. So much material has been moved from the upper western dig area that it was hard to picture exactly where we had dug nearly a year ago. I'm still not quite sure where we were in 2016 as the site has evolved greatly since our last visit. On Thursday and Friday there were mostly just a few volunteers who could make it to the site on weekdays--mainly retired folks or those with flexible schedules like us who could volunteer during the week. On Saturday there were a lot more volunteers and the dig site became a bit more crowded so you had to be aware of others digging sometimes in the grid square adjacent to yours. Here are some overall site photos I took on Saturday and you can see the line-up of cars that brought a full capacity of volunteers.
  11. Nice Sharp Tooth mosasaur?

    Hi: Me again. I found this at Aurora, NC Phosphate mine many moons ago. I am unsure if it's an alligator, mosasaur tooth or something else. Thanks for the help. David .
  12. Here are 4 very small jaw fragments??, that I would like to see if anyone could ID for me. I realize they are very small, but any help is appreciated as always. 3 pics of each jaw. Thank you, David
  13. Going fossil hunting tomorrow. Seeing dinosaurs like this makes one think twice about wading into that dark water. But it won't deter us. LINK Keep your eyes open when out there in the river.
  14. Alligator Tooth?

    Is this half an alligator tooth? Area was Miocene. It is about 1 1/8" long.
  15. My boyfriend found this extra large alligator tooth in Florida's Peace River. It measures just shy of 2" in length and is 1" in diameter at the base. Please share your giant gator teeth finds with me. Thank you! #zookeeperfossils
  16. After work last friday drove out to South Florida for a few hours of daylight to dig. But well worth it. 'Early on' found the most beautiful hemi lower, multicolored with intact tiny cusps on the side, my first. Had a gut feeling there had to be other good fossils nearby and wasn't wrong. Even found another stunning hemi eventually. Also a decent 'mako'/hastalis, couple horse teeth, big jaw section, my first quality tapir tooth, etc.. South Florida provides with hard work & many parts of luck. Overall my best fossil hunt of the year yet. I'm not sure what the skinny rib-like fossil is but I suspect fish? Only my 2nd pufferfish mouth plate, & usually I don't alter fossils too much, but there's enough solidified dirt if anyone has any tips for how I can clean it off without damaging the fossil I would deeply appreciate it. (P.S. No pics on the creek because my dry pak doesn't fit my current car key and my phone. I'll figure out something though)
  17. Croc tooth questions

    So Gang I've been watching the discussion about that Calvert Cliffs curved distinctly single grooved claw/tooth unknown and I think I understand why Harry was thinking not croc right off the bat and was looking at some of what I thought were crocodile teeth I had and want confirmation on a couple of things ... So I've got two specimens from awhile ago...Manatee County, surface finds so probably Peace River FM but I really cant confirm...Mio/Plio Pleistocene..a mix of marine/freshwater and terrestrial stuff... The first tooth has that noticeably multi small grooved striated look to it and seems essentially hollow which I thought was typical croc from other specimens I've seen. The other darker tooth has less distinct striations and seems to have a slight edge front and back to it and seems thicker and more solid...maybe its just nearer the end of the tooth and would be hollow otherwise? but that part of the upper part of the tooth is gone??? Am I dealing simply with two levels of preservation of croc teeth and the first is simply much more worn and a smaller, thinner tooth or is the 2nd an alligator or possibly even something else? All help is appreciated... Regards, Chris
  18. Prepped by transfer method. For about 30 years, I wasn't sure whether this juvenile crocodile is Diplocynodon darwini or Allognathosuchus haupti. Dr. Alex Hastings from the Virginia Museum of Natural History was so kind to determine it: "It looks to me like a young Diplocynodon darwini. I say D. darwini instead of D. deponiae mostly because of the general lack of osteoderms on the tail and legs. Allognathosuchus has more of a round snout/head, and even at this size would look more mature. The fenestrae at the back of the skull are still fairly oblong and the eyes are overly large, indicating a pretty young individual, maybe a year or two old. It looks a lot like several of the young D. darwini we had from Geiseltal, which overlaps in age and environment with Messel." Lit.: Rossmann, T. & Blume, M.

  21. Need Help Preserving Osteoderm!

    I was hunting the peace river a few days ago and found an osteoderm. I was overjoyed to be able to add it to my collection. I have wanted one since I started collecting! When I pulled it it was in great condition. I left it in a zip lock baggie so it had some moisture on the way home. I took it out and let it dry on my desk away from direct sunlight. i was picking some debris from the holes and noticed a very tiny hairline crack. Today it has grown much larger and seems to continue to widen. I don't know what to do as I am a nube. What can I do to save my osteoderm? What did I do wrong? What should I have done? What should I do in the future with specimens like this? (Sub dermal wet bone) Please help.

    Assortment of Crocodile & Alligator teeth collection from Morocco
  23. Hi all. I recently picked up this lovely specimen of a crocodile tooth. It came from the Solo River of Java, and is most likely 200,000 years to 2 million in age. I am aware that there was more than one attempt to identify the Solo River crocodile fossils in the past, but without any conclusive results. > http://www.thefossilforum.com/index.php?/topic/41300-crocodile-fossil-sangiran-indonesia/ It has two distinctive ridges that run down either ends. My extant Siamese Croc teeth have these ridges too. However, this croc tooth is slightly straighter and more cone-like. The bottom is quite unusual for a tooth. Besides C. porosus, are there any other possible species this tooth might belong to? A Google search yielded no results, and i have not located any sellers online who deals in these. Thank you.

  25. Cool Little Bone, What Is It?

    Here's a little bone I picked up today on the Brazos. I have a couple of ideas but will wait to see what the pros say first.
