  1. 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!
  2. I took a long 8 - 10 mile hike at NSR. The weather was beautiful and wildlife abundant. I saw hogs, deer, beaver, hawks, ducks and geese among others. I picked up a nice variety of fossils. I really like the Xiphactinus jaw with replacement tooth showing. I sat down to take a break and found 4 shark teeth in one area. The little fossilized turtle scute is also cool.
  3. I only had 4 hrs to hunt today but I still managed to find one large thick piece of fossil turtle shell, possible fish fossil bone, mosasaur vert and 3/4 of a point. Such a pretty day.
  4. Found in the Austin, Texas area. Previously a mastodon tooth or gomphothere. I thought Mosasaur at first look. Then elephant cranium fragment. One side has a def. curve with thin outer bone layering. Inward is pitted similar to pitted and highly porous Mammoth cranium I have found. I will slip an all 4 sides photo of the fragment in a second.
  5. I'm posting 4 Peace River fragments with some interesting features. Not sure they are all identifiable
  6. These are a few of the pdf files (and a few Microsoft Word documents) that I've accumulated in my web browsing. MOST of these are hyperlinked to their source. If you want one that is not hyperlinked or if the link isn't working, e-mail me at and I'll be happy to send it to you. Please note that this list will be updated continuously as I find more available resources. All of these files are freely available on the Internet so there should be no copyright issues.

  7. Hi, I'm new to this fossil stuff but it fascinates me. I found this in the head waters of an east coast river of the north island of New Zealand while hunting other things. I get around some remote country and every now and then find something like this but my knowledge of this sort of thing is limited. Can anyone please tell me what it actually is and if its of any significance please. Cheers Dayle
  8. Dear Guys, I am young fossil explorer from Lithuania, Baltic States. There are some Jurassic and Cretaceous erratics in my area, where should be possible to find some reptile remains. I think this type of rock is very common in Devonian but when I showed one fragment to scientific doctor in Vilnius University he said that similar rocks can be found even to Cretaceous. The tooth is quite uncommon in the majority of bony fishes because of its appearance, I think. It is more characteristic to crocodiles or other reptiles. The length of the tooth is 8 mm. The turtle scutes in my opinion are too big to placoderms like Asterolepis or Bothriolepis, and they are also very thick. There are three fragments of them, the largest is 2,5 cm in length and 4 mm thickness, the second is 2,1 cm in length and 3 mm thickness, and the third- 1,6 cm in length and ~2,5 mm thickness. Please help me to confirm these ideas if you can. Best Regards, Domas
  9. Hi, I thought I'd share some of my best finds from yesterday's trip to Hamstead. It was definitely one of the best trips I've had in terms of the sheer number and variety of fossils I picked up. Tide was going out slowly so had to spend a lot of time climbing over and through the fallen trees that litter the beach from the landslides, but it was definitely worth it. As usual fragments of Emys carapace were by far the most common find along with loads of worn pieces of crocodile scute and fish vertebrae. I also found quite a few of the nicer pieces that come out of the Bouldnor formation including a diplocynodon tooth, mammal teeth and bones (which seem to be quite common at the moment), 3 diplocynodon vertebrae, a large section of diplocynodon mandible, and the largest fragment of Trionychid carapace/plastron I've ever found! The coast is always very productive but the strong winds and rain we had here for much of last week seem to have exposed/brought in lots of new material. I'll attach images of the highlights from the trip below (will have to do it in multiple posts because of size limits). (Below) The best Emys fragments of the day, a large plastron piece, a neural plate, and a peripheral piece.
  10. Found this last Friday on the North Sulphur River. Was thinking possible turtle fossil of some type but haven't really been able to confirm this.
  11. Hi all! I found this specimen recently at a site in NE Mississippi (cretaceous). I kept it because I thought there may be a chance it was a piece of a turtle shell. I say this because one side is flat, and the other has a porous/spongy appearance. Am I on the right track, or do I have a nice rock? Thanks!
  12. Can anyone identify any of these pieced. I'm not sure if they are turtle shell fragments, dermal scutes or something else. There's four pieces in the photo - back and front images of a couple. Thanks in advance.
  13. A fossil my father found on the dunes of Venice, Florida. We thought it was fossilized turtle shell, but not 100% sure.
  14. wondering if this is a procoracoid from a turtle.
  15. Hi this fossil was given to me and I think it was found on the jurassic coast uk. I have been told it is part of a turtle , crocodile skin or part of fish brest plate. So I would like to throw it out there and see what comes back. It does have a fold shape to it , like skin? Thanks for your time in reading this post Bobby
  16. Was on the Peace River Florida- am sorting the findings had several flat pieces I think are mostly turtle scutes-but I'm not sure about a couple, and wouldn't mind more specific information on any image 1 shows the top of 8 scutes/flat pieces except it shows the underside of specimen 3. Image two is the reverse of specimen 3 I can make higher resolution or other views as needed.
  17. 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: 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: 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: 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.
  18. Long 10 mile hike at NSR and some meager finds. The weather was beautiful so I didn't mind. I found lots of Pleistocene tooth enamel. This particular area of NSR I seem to find more Pleistocene material and points than Cretaceous material.
  19. North Sulphur River Texas was pretty picked over but I managed to find a nice variety. I found Mosasaur, Cretaceous Turtle, Ammonite, Enchodus / Shark Teeth, Ice Age Tooth, Rudists, Mastodon Tooth Enamel and one artifact in the creek. NSR needs a good rain.
  20. I am interested in this turtle. According to the seller, it is from the Cretaceous of Liaoning, China. What do you think - is it real?
  21. I have a turtle fossil that I need help with type and time period, found in Texas, 7-8" long, 6" wide 2-3" thick weights almost 4.5 lbs. thanks for any help
  22. Hello: I am going through my collection of fossils when I was a kid over 30 years ago and it seems that I either forgot what these are or they were mislabeled. So any help is appreciated. Most of these fossils that I will post are either from the beaches of North Carolina or of some fossils quarries, like Aurora Phosphate mine, Castle Hayne, etc. I appreciate it! David
  23. I've found these 2 skulls in the lower eocene of southwest France I gave them to the MNHN of Paris because they are a new genus Adan Perez Garcia published a study and gave the name of species in my honour. Thanks for him
