  1. I found this mandible last year, and have been trying to id it. I think it's squirrel, but I'm not sure. Difficult for me, since it's just a partial. If it is squirrel, genus/species ideas would be greatly appreciated. Thank you! Glacial deposits, E Kansas, USA Has no teeth. Missing lower and rear section of mandible.
  2. I collected this piece myself from the surface during a short stroll down the hill from the roadside stop where I had earlier purchased several interesting fossils from the local kids; they were apparently very used to having tourists stop at their hut alongside the main road from Mahajanga to Antananarivo. This appears to be a nearly-toothless mandible, but it has features that just don't match the standard shape of mammalian or reptilian mandibles. Yesterday, I showed the piece to an expert paleontologist at the Natural History Museum in my hometown, Basel, Switzerland. He performed his PhD work on evolutionary history of ruminants, and he pointed out that my "mandible" lacks 1) obvious dentition; and 2) the thinning of the dorsal aspect of the mandible that is necessary for attachment of the masseter muscle. He did not know what to make of it. I've spent quite some time today comparing mandibles from a variety of ruminants, and I find nothing similar to this fossil. Can anyone here place it? Can you explain why there appears to be only one, or possible two tooth holes along the mandible? Thank you for any pointers you may have. Mike

    Help ID Fossil

    Hello, A family friend passed away and left me his rock, mineral, and fossil collection. Much of it was labeled, but there were several boxes of odds and ends that I’ve been working to identify. I believe this is fossilized bone as it’s heavy for its size. Forgive me if this is just bone. I don’t know where this is from, but my friend collected in CA primarily in the 70s through 80s. Most of his stuff was from local shows around that time. Any ideas of what this might be?

    Whale bone, but what?

    Largest piece i've come across. Yorktown formation - VA. It was found with what I believe was a bunch of smaller whale skull pieces. I'm at a loss for what this could be. Doesn't look quite look like a skull piece, or mandible, or rib, but i'm not an expert. There is one smooth section on the inside of piece, maybe helpful in identification. I would love others thoughts on what they think it is? Thanks!

    Mosasaur Mandible Genus ID

    Good morning y'all! First post here so lemme know if I am breaking etiquette or something ^^ I'm very much so a novice when it comes to identification, and am having trouble with this particular specimen. I know for sure this guy comes from the Pierre Shale in Wyoming, and it was found several years before my time. I am leaning towards Platecarpus because of the lithe frame and smaller size (appx. 300.0 cm from dentary to articular), and the fact that it seems to only have 11/12 teeth.

    Jaw bone of what?

    Found both of these jaws in Joshua creek that runs into the peace river. Any ideas on what they can be ?
  7. Hey folks, this is my second post attempting to identify a potential fossil. The last time members confirmed I had found a 350 million year old horn, coral fossil. Thrilling!potential fossil #2 is a very interesting looking rock. I recently picked up in Sequatchie Valley Tennessee. The more I looked at it the more I started to see a potential mandible, fossil or possibly teeth. Please review the pictures and let me know what you think probably seen one two mini PBS documentaries. Lol
  8. Need some help with this piece of Mandible please. Thank you!

    Basilosaurus jaw?

    Is it just me, or does this look like there’s a good chance that it’s either totally separate pieces with significant restoration connecting it, or even just quite a bit of fake areas? I feel like especially from the right side, it appears to be a huge amount of just matrix visible, and even on the left side a good deal of area that’s just matrix. I know that matrix isn’t unusual on pieces, and I wouldn’t mind small amounts of restoration/places of matrix filing in missing areas, but not large portions of something.

    Bobcat Mandible?

    Found in West Texas (Rocksprings, Texas.. Sutton county). Found this while walking a ranch. Pretty sure it's a bobcat mandible, but wanted confirmation since I'm new at this. Anything helps!

    Creodont from Quercy

    Hello, everyone I recently got this nice carnivore mandible from the upper Miocene of the phosphorites of Quercy. Unfortunately only two molars are preserved but their morphology are definitely Creodont like (Hyaenodontid). Now in Quercy several different Creodonts are been found. I searched through bibliography and photos and I think the morphology and dimensions of the mandible are very similar to Cynohyaenodon (cayluxi). What do you think about it? Do you have other hypothesis and ideas?
  12. Hi everyone, I'm looking to trade this big Mammoth lower mandible (+M3 molar) to trade for Megalodon tooth / teeth. Looking to find chilean, peruvian especially. Shipping will be split or evened out. - 43cm - 23cm molar - 7 kilogram - Netherlands, North Sea - Small crack filled professionally You are interested. Please DM me.

    Another small jaw

    Small jaw found in Southeast Texas. Looks consistent with the other Pleistocene fossils I've found in the area. Since everyone was able to help with the other jaw, I figured I'd give this one a shot. Thanks for any help!

    3 teeth and half a mandible

    Hello all. I have a few fossils for you guys to take a look at. Hope it’s ok if I stick all 4 of them in one topic. My father pulled these out of the wall or side of a 50 m/164 ft deep lake on one of his diving expeditions, Vinkeveense Plassen in the Netherlands. The lake where these were found was formed when a layer of peat/turf was removed to be used as fuel, below it was a vast layer of sand which was dredged up to a depth of about 50 meters m / 164 ft. The fossils themselves were found at depths of 30 m / 98 ft to 40 m / 131 ft. As my dad told it to me, they were basically sticking out of the peat wall that formed the edge of the lake and he just plucked them out. Considering how deep these were buried, I suppose they could have been deposited somewhere during the last ice age. I photographed these over a year ago and totally forgot to put ‘m up here back then. Unfortunately I also forgot to put a ruler next to them for scale, but if needed for identification I can still do that. Very curious to see what you guys make of these.

    Rodent jaw

    I found this mandible (I think) near Bloomington, Indiana over the weekend and was wondering if anyone could give me an ID on it. I believe it's the mandible of a rodent, but that's about as far as I get. Seems to large for a mouse or rat, but maybe a muskrat, shrew (if those are bigger?), or squirrel? And I'm guessing it's more recent rather than fossil?
  16. Hello everyone, can you help me identifying this mandible fragment, I'm unsure of what it can be, maybe Raccoon or a mustelid. I'm sure some Florida expert can determine much better than me what this can be

    Nimravid! But which one?

    Hi guys! Recently I got in a trade this nimravid mandible from the white river formation in Shannon County. Now I want to ask your help to determine the genus, if possible. Being incomplete and missing all the teeth it's quite difficult but it has a quite elongate mandible flange and by the number of the alveoli it had three teeth. I think it can be Hoplophoneus, what do you think about it?

    New member fossil ID

    Hello Everyone, I am a new member on fossil forum! However, I am not new to paleontology. I am 13 and have been obsessed with fossils since before I could walk. I have two fossils I need identified, the first one is a jawbone I bought at a sale from a private collector. I recognize that it is probably not valuable, but I would like it identified. The man who sold it (he was a naturalist) identified it as a herbivorous lizard's partial mandible, anybody able to shed some light on it? The other fossil is what I presume to be a footprint cast, I have had two geologists look at it and they can't find anything to disprove the fact that it might be a very small cast of a Theropod footprint! I found it in some yard rocks (like most of my finds) and it doesn't seem to be your typical Grallator. This is either an interesting find or the pareidolia hoax of the century! If anyone can prove/disprove it, let me know. Thanks! (I'm going to reply with pictures of the jaw since they exceed 3.95)

    Cameloid skull and ramus- NE SD ?

    Whew. Last one with identifying marks to identify. Is a museum cast. UNSM 4616 Sure, I could email the collections curator at Morril Hall, but I’m afraid to wear out my welcome. As of yet have been unable to find data on this one on my own. Figure I’ll give yinze a crack at it before I bother the museum for the twentieth time. My research shows this to be a camel of some sort. It is likely Nebraska or South Dakota in origin for the original due to the provenance of the other casts yinze have seen me dealing with the last few weeks. This is a pretty poor cast with lots of missing parts broken off from poor storage. In fact, it is so bad I’m considering doing a full on arty reconstruction as it is not suitable for display or education in its current form. Due to the pigmented plaster, it does not photograph well. Cannot find a single reference to this number online. ( doesn’t help there’s a wristwatch and a snake fossil with similar ID numbers) Any ideas? I really want to finish ID of these casts so I can focus on real fossils!
  20. Location: Missouri Time period: Pennsylvanian Formation: Muncie Creek Shale Specimen 1: Fish Coprolite? 1.8cm (nodule size) Specimen 2: Coprolite? 2cm (nodule size) Specimen 3: Fish Mandible? (2.6cm) Specimen 4: Coprolite or Maybe Braincase (I think it is very unlikely that it is) 2.8cm Nodule size 1.5cm (fossil size) Specimen 5: (2.9cm) Note: The placement of the fossilized material might be wrong as this was one of my first nodules and the fossilized material fell out. I recovered what I could. (Opened roughly 2 months ago) Specimen 6: Tessellated Cartilage with some Skin impressions ? (2.5cm) Specimine 7: Fish material? Thank you for reading and viewing this, I hope I can better understand these images so I can use them as references in the future!

    Calvert cetacean mandible ID

    Found this mandible in a rock fall at Calvert cliffs in June. I believe it’s mysticete because of the lack of tooth sockets, but am open to complete redirection if I’ve got it all wrong. Any ideas?

    Possible bison find?

    Hey everyone, So I found some old bones as I was out hiking yesterday (a good way to social distance ). I have a suspicion they may be bison, but I realize I am in ag country were cows are plentiful. I found a scapula, a chunk of upper jaw with teeth, two femurs, and one mandible. I have been trying to possibly identify them but I have no way of proving anything without some help. I grabbed a cow skull, scapula, and mandible at a friends farm to help compare. I guess I should also point out that I believe these have fossilized- they are heavy and the burn test seemed to yield no burnt hair smell. Photo 1: Fossil Scapula (left) vs Cow Scapula (right) So the scapula I found is bigger but I don't believe that is conclusive evidence. Photo 2: Fossil upper molars (left) vs Cow upper molars (right) It appears the fossil molars are larger than the cow molars.... possibly indicating a larger bovid (aka Bison)? Photo 3: Fossil mandible (below) vs (Broken) cow mandible (above) I know the cow mandible is broken (and the opposite side as the mandible I found) but it is shorter and has more bulk at the bottom of its lower jaw curve. Not only this, but the dentary also appears different. Well everyone, what do you think? Just a regular old cow? Or something more unique? Thanks!!!

    First for my collection

    Found this a couple of days back... how hard could it be to identify? A lower predator mandible with 1 complete carnassial and two half teeth, vertically split. How many small predators existed in the Florida fossil record? Look at the m1. That is different from both the canid (fox, coyote) m1 and felis (margay, bobcat) m1 you can find on TFF ID threads. So I checked out raccoon and possum ... nope!! Then I started looking at research papers comparing different type of predator m1s. I was always looking for the smaller predators. Then I stumbled on an old TFF thread, http://www.thefossilforum.com/index.php?/topic/78879-mammal-tooth/ and once again @Harry Pristis makes an ID. His photo pictures across the internet are an invaluable resource to the Florida Fossil Hunter. Most TFF members, except Harry, will need to go to the thread above to find the ID. This is the very first fossil I have from this animal, and I am very pleased to add to the collection. I have always had a curious mind. No surprise that I have questions: 1) What is going on in that 1st photo? Is this some creature like the worm bore that carries a little chain saw, and slices off half of the p3, half of the p4, and leaves a demarcation line down the side of the m1? Exactly at the halfway point of all 3 teeth. Sometimes I feel paranoiac.. 2) More specifically, for those that have one of these in their collections, large, medium, small example? 3) Is there one specific animal in the Florida fossil record or a couple of options. So far I have seen at least one latin name and imagine there are others. Thanks for the good wishes , any and all comments. Jack .cc @jcbshark
