  1. Hello! This is a small fossil from the White River Formation of Weld County, Colorado. To me it appears to be a set of front incisors rooted to a small piece of the maxilla or mandible. There are no teeth or tooth sockets next to the two that are there, and so this makes them look like the two incisors characteristic of rodents and lagomorphs. Interested if anyone can tell me anything else about them. Two photos are through a stereo dissecting microscope at 20X magnification, the other two, though blurry, should give a sense of scale. The entire fossil is about 9 mm tall, with the tooth crowns themselves being about 4 mm tall. Thanks!
  2. I made a drive to explore a new creek in Hill County Friday morning. It ended up being some of the toughest hiking in a creek bottom I've done. This is another Eagle Ford outcrop, and in satellite photos, the blue-gray shale went from the sides of the creek walls all the way to the bottom of the creek bed, just like the Ellis County creek I visited last week. In real life on Friday, the creek bed was full of mud, and it covered much of the lower walls of the creek too. I've never seen such a difference in a reasonably recent satellite photo and actual appearance. To make matters worse, it rained Thursday. I didn't think the showers had reached that far west, but I was mistaken. It didn't raise the water too much, but it made the creek bottom a muddy mess. I've never before gotten this muddy hiking a creek, and it really wore me down, sloggin through that. With the mud that high, there was no finding any fossiliferous layers of matrix anywhere in the creek walls, but there were plenty of broken pieces of it, along with shale pieces, in the bottom of the creek. So, I spent my time looking for individual fossils on the gravel bars (more like mud bars). But the rain had turned the shale really dark, and that along with the dark brown mud, made spotting fossils really tough. I picked up lots of likely looking pieces of matrix too, and I did find a few things. Here are the only teeth I found that weren't seriously encased in matrix. I really should stop picking up modern bison teeth, but can never seem to resist them.
  3. Rays tooth for id

    Hello! Help please with identification. Age: most probably - Miocene.. Western Ukraine. Thanks!
  4. These two teeth look similar to me, and I think are probably from the same type of animal, but I'm not sure. They were found close together on a central east coast Florida beach. Each is just over a quarter inch wide. The rule marks on the one picture are 1/8 inch. Thanks for all your help.
  5. Can these 3 be ID’d?

    Tiny items, 1/2 - 1/4 inches, picked up in Big Brook that caught my attention and warranted being brought home. Teeth? Bivalves? Concretions? As always thank you for sharing your expertise
  6. Very small shark tooth for ID

    Hello! Sorry for bad quallity photos and I understand that tooth is broken, but this tooth is very small (max. length ~1,5 mm) and has interesting shape. May its possible to identify? Western Ukraine. Most probably - miocene. Thanks in advance!
  7. Diplodocus teeth

    It is easy to find diplodocus and camarasaurus teeth on fossil e-shops? I have see 2-3 teeth over 2 years ago.
  8. Hi everyone! This tooth was found at Perú, at Nazca desert zone. I'm supposing that is a Megalodon tooth but maybe, you experts, could give me some more extra information about kind of Megalodon, size or age... I don't know really, but my son is asking me about and some more expert information will help me a lot ;-). The size for rule is in centimeters. Thank you very much for your kindness!
  9. Who was the former owner for this tooth?

    Hi everyone! With my 6 years old son we have bought this precious tooth in a prestigious shop at Barcelona. They have tell us that is a Mosasaurus tooth, but I think not. It looks more a Spinosaurus tooth, maybe (sorry if I'm talking absurdity, I'm totally newbie...). The teller at shop was not the usual one, and it was not possible to ask him more information. Please, may you help me to identify the correct "former owner" for this tooth? My son and I will be very grateful for that. I'm posting some photos for the piece. The first one is from the other pieces at shop, that we didn’t bought. The size for rule is in centimeters. Thanks a lot for your kindness!
  10. Fossil found Ponte Vedra Beach

    Found this fossil on Ponte Vedra Beach. Looks like some sort of mammal tooth maybe but I’m really not sure. About 1 inch wide and tall and .5 inches width.
  11. Here is a tiny jaw with three teeth. It is small. The three teeth together measure about 5/8 inches wide. The marks on the rule are .25 inches. Thanks for your help. The item is from a beach near Jensen Florida.
  12. Hope everyones week is going well. Over the past week I found a couple teeth and something that looks like a fried egg. I just wanted to get some confirmation regarding the teeth and I have no idea what the 3rd item is. Thanks for all the help. 1. I think this is symphyseal tooth but not sure. 2-3 MM 2. Thresher shark 3MM; not sure because the root seems to fat. 3. Fried Egg looking thing; It is the same on both sides 2.5MM
  13. I have been wanting to make it back to the Ellis County creek where I found so many teeth, but by the time I could do it, it had rained enough to raise the creek quite a bit. The water level has just now dropped again. I was working near Ellis County this morning, and when I finished very early, it seemed the perfect time to go back. Rain is forecast for this evening and the next couple of days that will likely bring the creek up again. Below is what I found that was either loose, or easily removed from matrix.
  14. Hello! in the early 2000's, the Ring Road project in Hardin, County (Elizabethtown, KY) had been in progress. My father had a coworker friend who lived along the road and was able to obtain a few loads of the rock busted by contractors to be used in his yard. My dad scored some as well and it was used for landscaping. Ever the budding Geologist, I of course explored the rock pile and found this particular find to be both intriguing and perplexing. I've attempted to positively ID it for years. I've shown it to a shark expert, local geologists and the KY Geological Survey...none have a clue. Though they offered to buy it for a museum haha. They did say they think a fish or shark is most likely probability. Although I was looking forward to identifying it myself, I've wasted quite a bit of time attempting to do so and would like some assistance confirming the identification theories I have. Thank you! State: Kentucky | County: Hardin | City: Elizabethtown Strata: Since I'm uncertain the exact location, I used the Rockd app to determine the strata in the area. Results are: Ste. Genevieve Limestone, St. Louis Limestone, Salem Limestone. All late Mississippian.
  15. What is a micro?

    Good morning. Is there an accepted demarcation of what constitutes a micro? Is it 1/4 inch or smaller? These two Crows are 5/16 inches. The other photo is, I think, just a cusp which is 1/8 inch. Thanks all.
  16. Unknown teeth from Russia

    This teeth was found on Azov See shore, Russia. Taxonomic identification and geological time of this find doesn't know. Age of rocks from the late Miocene to the late Pleistocene.
  17. Im looking for my collection different megalodon teeth and vertebrae. If you want to trade I offer fossils from Europe. Thanks!
  18. Teeth Identification Assistance

    I am so new to this world that I'm still wet. But I'm super excited about the opportunity to learn and have fun. My first dive into the St. Johns River in Florida, and along with a bunch of sharks teeth, I pulled up these. The first one matches a picture of mastodon teeth that I came across, but these are tiny. Any idea what it is? The second one looks like the front teeth of some type of canine. Any ideas here? Please let me know if these types of questions, and my ignorance, is not proper. Thanks in advance.
  19. White River Teeth ID

    Hello, everyone, Lately this summer I’ve been doing a bit of casual fossil collecting (with explicit permission!) on some land that a very close family friend owns in Weld County, Colorado that has a lot of exposure of the White River Formation, and I’ve collected a sizable amount of material including some pretty awesome finds. Being an amateur, I need some help identifying some of the fossils I’ve collected. Since the forum has a photo upload limit per post, I’ll be making a few threads for different finds, I hope that is ok. The following are two teeth that I found very near to (but not attached to) a piece of jaw bone. My current hypothesis is that these two teeth are associated with the same jaw. From Weld County, CO. Though hard to tell from the pictures, tooth #1 does have a distinctive ridge at the apex of the crown, though this could just be wear. Tooth #2 appears only to be a fragment, and a small fragment at that, and so may or may not be identifiable unless it turns out they’re from the same animal and the first tooth is identified. #1: #2: Thanks!
  20. Work has been interfering with both my cycling and fossil hunting time lately. I managed a day off today and started the day with a 30 mile bike ride. But there's a creek in Ellis County I've been wanting to hunt, and I really wanted to get my first look at it while the water is low. With Hurricane Laura bearing down on the coast, I decided to make that hunting trip today, not being at all sure how much longer the water will be this low. It's an Eagle Ford outcrop I went to in this creek. With my late start, it was 11:00 before my hike down the creek got me to the outcrop. I left at 2:00, so only had three hours for my first time exploring it. The temperature was in the 90's and the humidity was high, so it was definitely stifling hot. It did cloud up at times, and actually rained for a few minutes. But it was mostly just sunny and hot. The outcrop is the typical blue-gray clay you find with Eagle Ford.
  21. Theropod teeth with no ID

    So I bought these tooth-fragments at a fossil show back in December in Hamburg, Germany. The seller had a lot of different fossils, including a huge ilium bone of a sauropod from the Kem Kem beds, as well as a tibia from a large indet. theropod (Which according to the seller was Spinosaurus). Other than that, he sold large tooth fragments from the Montana, Hell Creek formation, probably Rex, but no complete Rex teeth. Some dromaeosaurid teeth from the Hell Creek formation, and various herbivorous dinosaur teeth from the same formation too. A lot of ichthyosaur bones from Dotternhausen, Germany. Some fossil amphibian skulls, can't remember where from or what species exact, some of them were still in a matrix, the bones were almost red and looked a bit similar to that of Eryops. He also sold small plastic containers of tooth fragments from China/Mongolia, labelled "Tarbosaurus". I bought one of these containers. The seller told me they were collected near the border between China and Mongolia. I was never truly sure if they were 100% Tarbosaurus, could literally be any other theropod. And considering there was no specific location or formation, it's really hard to tell what I've actually bought. I've had some people write to me, wanting to buy the fragments, and have each and every time told them, that I really can't know for sure what these fragments belonged to. Just recently I bumped into this tooth (as seen below here) online for sale: It is described as a Carcharodontosaurus indet. tooth from the Kem Kem beds of Morocco. And the coloration looked oddly similar to one of the fragments I bought at the fossil show. Now, before you say anything, I know that coloration varies a lot within every location, and some locations may yield fossils that look identical in coloration to other locations' fossils, but I just thought the reddish tone underneath the enamel seemed very familiar in regards to especially 1 of the fragments, which is a partial tooth, and also the most complete one from the little container I bought. (See the partial tooth below): The tooth on the above pictures has the following serration counts: Mesial carinae: ~18 serrations per cm, roughly 2 per mm. Distal carinae: ~20 serrations per cm, roughly 2 per mm. It measures: 2,5 cm at its longest dimension. 1,4 cm wide. About 0,9 cm thick at the thickest point. After seeing the picture of the Carcharodontosaurus indet. tooth for sale, I thought maybe this could be a Kem Kem tooth too. Anyone who's got a guess or a hunch?
  22. Teeth and more

    Dear TFF Members, these are the fossils I found during my last fossil hunt - I need help with ID No. 1 Skull and vert of? No. 2 A part of jaw with 1 tooth No. 3 Teeth of?
  23. Meg or great white teeth?

    Hi all! ive had these teeth in my collection for probably more then 4 decades and I always had them in with my meg teeth. But recent posts I’ve seen have me questioning that. They were given to Me When I was a kid starting out so I have no location or formation information. They may be too badly damaged for a positive I.d. But I thought I’d give it a try. Number 2 I’m still fairly sure is a meg Becuase the burlette is pronounced but number 1 and 3 are the ones I’m questioning. Thank you in advance!
  24. Is it a tooth?

  25. Starting to ID some of my peace river finds from last season and I'm going to need some help. I found these teeth all in the same hole I don't believe they're all the same animal though. Thanks, Dave
