  1. Please help identify

    Hello, my name is Brandon Rogers. My mother has entrusted me in scouring the internet and other sources to determine what exactly it is. A Chinese woman she once worked with gave her this and told her that it would bring her good luck. It appears to be two baby turtles fossilized together but no one on the family has the proper skills or knowledge to identify whether or not it is indeed a fossil. Please help!
  2. Is this genuine? Any repairs? It is so perfect that I’m not sure if it’s genuine.
  3. Hi, I'm new here. My husband and I bought a house in the Mojave desert last spring and have found many rock treasures there over the summer. The area we're in used to have volcanic activity in addition to ocean streams. We've found huge bones, tons of petrified wood, some oddly shaped rocks, points & frequently find seashells. Initially I thought this rock might be some old Paleoindian art. It looks a lot like a tortoise except I don't believe they've had teeth for millions of years. I found some photos of old tortoises which have a strange small white row of something bony along the bottom insides of their mouths so maybe? It could be some sort of petrified extinct reptile I don't know about - maybe it was buried in ash which preserved it's details, otherwise I can't explain why there are no holes as a typical skull would have. The back and side are broken off but I'm hoping to dig around and try to find them (and maybe a body?) on our next trip to the property. I'm confident there are other missing parts as the broken back and sides look nothing like the smooth side shown. I'm willing to accept this may just be a very cool looking rock and nothing more but I think the area I found it in being known for this type of reptile, the size, the perfect placement of the eye socket, 2 dots for the nose, and lower jawline would be a pretty amazing coincidence. If you look closely there are also scales outlined along the top portion. So cool rock or maybe something more, what do we think?
  4. A Pregnant Tortoise? Please Help

    Hi I found this in West Central Mn, it is 9inx7in and about 3.5in thick. It appears that what crushed it left a foot print. But looks are deceiving any help would be great. thank you
  5. Is this aggregate of tortoises genuine? How could that be possible to have so many tortoises piled up and turned into fossil?
  6. Tortoise fossil

    These two well preserved tortoise are from Gansu, China. I am not sure about what species they are.
  7. Is It A Fossil?

    Hi I am new to this forum. I live in Ca and collect minerals, fossils and as an amateur photographer, I am photographing some of my collections. These photos are of an unopened small geode (3 cm, or 1.25 inches tall). They are all of 1 specimen taken at different angles. Many decades ago I received a bag of small geodes all formed in the same light green volcanic ash. This was among them. No other geodes in the bag had this texture or pattern on the outside. I put it aside thinking it may be a fossilized impression from a prehistoric reptile or tortoise foot. I have never gotten a definitive answer. Sadly I can’t recall for certain the location for the source of the geodes, but perhaps it was Chihuahua Mexico. Is this a fossil, or merely some crystallization causing the surface to appear this way? Any help would be appreciated Thanks Tom
  8. From Butte to Beaut

    Thought I'd share a few photos of a tortoise prep I just completed. This is from the white river group of Chadron, NE (circa 33 mya). Here is a series of photos from discovery to excavation to restoration and preparation. The discovery: broken shell (As usual, I forgot to take a true "before photo". I've already probed a bit here). After some digging, it was discovered that this individual is upside-down. Here, the plastron is being revealed.
  9. Hi, I work at a fossil shop in Moab U.T., and for the life of me, I can't figure out what species or period it's from. I have reason to believe it's from China, but I can't confirm this. This has been on my mind for a long time, and any help would be greatly appreciated!
  10. Dear friends, Some weeks ago I bought a cretaceous skull from the Cretaceous Cenomanian from Morocco, but I am trying to classify it and I don´t find the proper classification in the bibliography from Morocco. I am considering that could be some type of species of turtle or even some type of species of other reptile (such as a sea snake). Could you please help me to define it? Many thanks!
  11. Reptile head?

    Found in landscaping rocks around my home. my son (10 years old) is very interested in it, so I'm trying to help him identify what it is.
  12. So I got gobs of turtle stuff as many of us Floridians have and there were all kinds of these guys crawling and swimming around here. I was wondering if any of you have run across complete turtle/tortoise jaw/dentary's and might confirm these fragments might be. So here are 3 fragments that have interesting textures. All 3 have a gentle curve/arch/narrowing to them. 1) seems to have a porosity/pitting very similar to alligator or croc and I'm not sure if that immediately excludes it as part of a turtle jaw.
  13. ...at least for me for this season. I'll be out of the country over the next two weekends and then off to Greece on vacation for most of June so I'll likely not get another chance at hunting the Peace River this season unless something really unusual happens with the weather. I expect rainy season to have started by the time I'm back from Greece and the Peace will likely be several feet higher that it is at the moment. Currently, the Peace is as low as I've seen it this season. During a heavy drought several years back I've seen the Peace about a foot lower than it is now which made for a long trip from Brownville to Arcadia with a lot of time out of the canoe pushing it over shallow sandy areas. Yesterday, we had to get out a number of times and that combined with the headwind we fought all the way back to Arcadia meant we had to allocate more travel time which left less time for digging and sifting. On the (Canoe Outpost) bus ride up from Arcadia to Brownville we spotted a couple sitting the seat in front of us who looked to be new to fossil hunting on the Peace. They had loaner sifting screens and a shovel from Canoe Outpost and I figured we might help introduce them to a fun (and addicting) passtime. We hadn't planned on spending much time at the large (well-known and hard-hit) gravel bed just downstream from Brownville but changed our plans to help Mike and Samantha (if I haven't misremembered their names by now--names, not my strong suit). After a brief stop before the main gravel bed we stopped at another area with very chunky gravel that is even closer to the boat ramp at Brownville. This area is well within walking distance from Brownville Park and I suspect it gets hit hard by walk-ins. Lots of gravel to be found at that spot but it wasn't even giving up small shark teeth so we soon moved down to the primary gravel bed near Brownville. I gave some tips and pointers on how to hunt the area and let them use our larger sifting screen with 1/4" mesh while we poked around with the 1/"2 mesh sifter trying to find an area that was producing fossils. The gravel bed at this location is virtually from bank to bank and runs for somewhere between 100-150 feet so it is not a tiny area. Even though it is large it is by no means cryptic and it attracts lots of attention. Evidence of holes and piles litter the bottom here (till they are erased like a big Etch-a-sketch each summer during flood stage). The big trick to hunting this site is to find some place where you are not digging through someone's spoils. Prospecting lots of sites in this location till you hit an area that is producing some nice finds is the best way (IMHO) of working this location. We poked around without much luck till we found an area that my probe told me had some gravel under a topping of sand. Within a few minutes digging there I pulled out a rather large chunk of giant tortoise (Hesperotestudo) carapace that should have been identified and kept by any previous hunters. This made me feel more certain about spending more effort in this spot. Before long we were pulling out some larger shark teeth (and fraglodons) as well as a few other things like gator teeth and mammoth and mastodon tooth fragments. Every so often I'd bring over some donated finds to our new "students" so they could start to understand the diversity of finds that can be pulled from the Peace. I continued to dig in the spot we finally landed on as it was giving up a variety of small prizes which were useful in demonstrating the types of things to look for in the Peace. Shark teeth are relatively easy to find and identify but more obscure fossils require obtaining a search image to be able to spot effectively. Shortly after I had shown the river's two newest fossil hunters a small piece of mammoth tooth we pulled something interesting out of our sifting screen. Tammy got to it first (she works the sifter while I man the shovel). Initially, she thought it was an odd piece of turtle shell (a good assumption as the Peace has lots of varied pieces of turtle and tortoise carapace). She had picked it up and was holding it sideways. I took it from her to look closer and upon rotating it saw the occlusal surface. "Horse tooth," I said instantly seeing the crenulated enamel ridges on the top of the tooth. But something was odd about it--it just didn't look right. Lower horse teeth are more narrow and elongated (better to fit into the narrow lower jawbone) while upper horse molars are more squarish. This piece wasn't quite square nor was it as elongated as a lower tooth should be. It was the right size for an Equus molar but the square peg just wasn't fitting into the round hole. Finally, the penny dropped and I excitedly understood why this horse molar looked so odd--it wasn't equine at all! It was mammoth--BABY mammoth! I went over to show this new find to our fossil partners do jour and while I was explaining to them how you could tell it was mammoth (by the very characteristic bands and loops of enamel sandwiched together with layers of cementum) Tammy came over and said, "Guess what I found?" I hadn't a clue--the Peace can give up a wide variety of items. She held out in her hand another chunk of baby mammoth tooth--one entire loop of enamel. It only took a few seconds to verify that this piece fit neatly into the chunk we had just found--the tooth was growing! You can be sure we dug around in that spot for another hour or more but never found another scrap of this tiny tooth. Likely it had previously fragmented on its path from where it was eroded out of the river bank to the spot we recovered it. The two pieces had probably recently separated but didn't make it far from each other--they may have even separated just with the agitation of shaking the sand out of the sifting screen. I'm glad we were able to reunite this pieces. Still, by no means a complete baby mammoth molar but a good size chunk and my trip-maker for the day. I had originally planned on skipping past this location and prospecting some other gravel spots we have hunted in the past but haven't tried for several years. I'm glad the decision to instruct some newbie fossil hunters paid off so quickly with fossil Karma. Before too long our new acquaintances headed off down river and we soon gave up our search for any more of this molar and continued down as well. On the way down we spotted a large gator in the same spot as we saw one when we were there last time. It looked to be about the same size (9-10 foot) and I suspect it was the same individual in its current favorite sunning spot. We prospected a bit here and there but had spend so much time near Brownville that we wanted to make it down to our favorite spot near Oak Hill. We stopped again at this location to hunt for a bit because it has chunky gravel and sometimes gives up nice prizes. Mostly, it's just big chunks of matrix with lots of dugong rib bones and very few shark teeth but this is the same spot that gave up two nice gator osteoderms last time out. The water is quite low without much current at the moment. If fact, the wind that was blowing steadily from the south was actually pushing my sifting screen upstream. You can see from the photos below that the water is also quite cloudy as there is a major algae bloom going on presently. This is making the normally tea-colored clear river water quite opaque and greenish. Vertical visibility is less than a foot. This lack of clarity is not impacting fossil hunting too much but it makes the paddling downstream more difficult as it is making the sand bars and deeper water channels more difficult to discern. Hidden logs below the surface are also more difficult to see making for more dangerous navigation. We had to think more while traveling but since we know this stretch of the river pretty well we didn't have major difficulties. Here I am enjoying the Peace for my final trip of the season. This second stop of the day didn't give up any large prizes but did produce a nice diversity of items. The second find of the day was this tiny jaw with several molars in place. It looks to be something from the a rodent or lagomorph but I'll need to spend more time getting an ID on this.
  14. Tortoise Prep

    I've just received a massive tortoise prep job, which will be my summer project. It measures nearly 14 inches long, and somewhere around 12 inches wide. At its peak it's six inches tall. This will be quite the project (though after I clean and replace the broken side, it'll be a breeze compared to some other preps) I'm still in the planning proccess of this prep but I'll start by assembling the smalles peices togethor, and work up to larger chunks. I'm glad to actually be on the forum again.
  15. Domed shelled tortoise

    Cylindraspis peltastes (Chelonoidis nigra) type
  16. Tortoise shell repair

    Well I finally started repairing the shell I got in Denver. Starting with the bigger parts, with obvious placement and working out. Currently holding a part as the glue dries Im using a 5 minute epoxy on these two sections, mainly due to difficulty holding long enough for a 30 minute or two hour one. The shell is not as yellow as in this picture. warning, this will be a long documentation of my work as I go along
  17. Stylemys nebrascensis in situ

    From the album Fossil Discoveries

    I wanted to capture an angle that evoked the feeling of encountering this animal's fossilized remains where it may have actually died.

  18. Stylemys nebrascensis in situ

    From the album Fossil Discoveries

    I visited the Badlands National Park in spring 2016 and photographed this badly weathered fossil turtle where it died some 30 million years ago. I subsequently informed a park ranger where I had seen the specimen.

  19. I'm fairly certain this is a humerus, but to what? I am a herpetologist and spend a lot of time along rivers. I came across this today as I was searching for frogs, and I decided to hang on to it to ID it. So far, I have been unsuccessful and I assume you guys are way better at this than me. The bone/fossil doesn't feel as heavy as most fossils I have come across, but it is definitely heavier than bone. It is completely black underneath the crispy tan layer shown in the photographs. It was found in an area along the river bank that had recently been washed out due to recent rains. So I'm not certain if it originated high above the bank or in the wet sand. Thank you, Buddy
