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?

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!!!

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

Good evening I just now found this tooth so I begin digging around and have discovered the maxilla in the mandible including a whole bunch of teeth! But they are falling apart! I have pieces parts of everything else besides this one tooth! Does anybody happen to know what animal would have A tooth like this?

Mammal jaw from Big Brook, NJ (+ a few other questionable bits...)
Diplotomodon posted a topic in Fossil ID
On a whim I decided to stop by the Big Brook site in NJ to see what might have washed up after the rain yesterday...not a lot of shark teeth at all but plenty of weird mammal bits for some reason! I'm not good at all with figuring out mammal material so I figured I'd post some pictures to the forum and get people's thoughts. (Also I suppose it remains to be seen whether this is genuine Pleistocene material or stained, semi-recent bones...) These are smartphone pics (& Android at that) so excuse the quality. This first one is a tiny jaw of what I'm assuming is a rodent of some kind - the size is really throwing me off here. The same jaw is here on the bottom alongside a couple goblin sharks, plus an end of a random limb bone up top. Horse teeth? (The ends on both are broken, unfortunately - these are the most distinctive edges) (image size limit reached, more in next post)

Found a tooth walking along the gravel/sandbars of a creek in central Iowa (Des Moines lobe) and came across the tooth on the right. I was surprised to find both these jaws about 1,000 ft apart and a mile downstream. I assumed they were the source, but looks like the loose tooth may be an upper (it's larger) and both these jaws seem to be full. The teeth don't seem to match up symmetrically either, making me think it might be different individuals. Modern and ancient bison remains are pretty commonly found here (the former being extirpated ~100 years ago), but I figure cows are just common enough to confound things. They seem to have the stylids I read about, but I can't tell if they are strong/prominent enough to be Bison. Any help would be appreciated!

Hello member of TFF. I finally got a chance to really dig (sort of pun intended) into some matrix I bought back in December of 2013 from I believe tj102569 (but it's been so long I cannot find the sale post anymore). If I remember correctly the matrix was from a quarry in possibly Grant county South Dakota. But it was definitely from a quarry in South Dakota (yeah I know there are more than one). The matrix is pretty hard. Engraver and dental pick don't do much more than scratch the stuff. The seller at the time said he used a hammer to just break it open and find sharks teeth. But I was after large and micro fossils so I didn't like that path. I started to use regular 3% peroxide with a small amount of success and combined with the engraver found a few things, but not as well as I would like. So I store the matrix away until I could find a better solution. Flash forward to now in my new prep room and some 12% food grade peroxide and I get results I like. The 12% really breaks down some matrix. Word of warning though I measured temps of 167.4 Fahrenheit so if you chose this method be sure to use containers that are good with cooking temps (old food grade containers are what I use). Anyway low and behold I believe I have found a mandible. But it broke on me as I was picking it up with tweezers. What do you think? And this is the starter matrix. Thanks for your help.

From the Meherrin River in NE North Csrolina. Local geology and preservation suffuse Plio-Pleistocene. I've eliminated tuna, grouper, wahoo, seabass, drum, sturgeon and tarpon. Im out of ideas. Thoughts?

I have two mandibles from Asia probably Siberia that I need help IDing. #1 is a hair over 4" and the most complete tooth has a pointed premolar. #2 is 6 1/2" and all the teeth are complete besides the first molar. It looks very similar to some deer mandibles I have but the teeth are twice the height and half the width. Thank you for looking! #1

Here some pictures of my FOTM prep. Unfortunely, I have no pictures of the skull prep. Only the mandible

The plesiosaur has long been one of my favorite prehistoric creatures of all, especially after reading tales of the Loch Ness Monster. I've always wanted a jaw from one, thankfully @StevenJDennis recently scouted this beauty for me from Tucson. I estimate roughly 30% restoration, mainly to the rear portion of the joint(?) and some filler. Also, majority of the teeth have been planted from Zarafasaura oceanis, another elasmosaur. Still, he's earned a spot as one of my showpiece fossils. He measures 17 inches long and 7 inches wide. Plesiosaur Mandible Elasmosauridae (Libonectes atlasense Buchy, 2005) 94.3 - 89.3 million years old | Turonian, late Cretaceous Akrabou Formation Asfla Village, Goulmima, Errachidia Province, Morocco I assume this is an erupting tooth

Item 1: This has been suggested to be dire wolf or cat. Can we get more specific?

We were exploring the Hell Creek Formation in Montana, and found very similar sections of jaw bone. It seems like structurally, this section was the strongest and most likely to survive. As you can see, they are very small... Any idea on what these might have come from?? Thanks for any tips!

Hi dears colleagues!! I found this jaw fragment with 3 teeth. appear to be incisive and the mandibular fragment includes part of the mandibular symphysis.Does anyone have any idea what it is? Regards

HiI've had this section of a mandible for a while. It was from a rock collection left under a house when tenants left. Think it's Mammalian, but possibly reptilian? Could use help to determine. Thanks.

I found this in a creek bottom in central Ohio after a flood that caused extensive erosion. I'm thinking it might be a fox or coyote, but really don't know. I was hoping someone with more expertise in this area could assist me in identifying it. Thanks, Mark

This is not a fossil, but I brought it home any way from a river hunt. Is it domestic dog or coyote? I have looked at several images on line and cannot see a difference.

Hello everyone! My name is Jack, and I am hoping one of you can help me out. To be clear, I have zero experience or knowledge when it comes to fossils. I absolutely loved dinosaurs when I was a kid, which led to my parents buying me this fossil of a partial mandible and teeth. I've starred at it ever since, always wondering what it might have been. I was cleaning out old boxes and I happen to find it! Last time I laid eyes on it was in the late 90's so I never had a chance to get it looked at. If there is anyone who would be able to give me some information on it, it would be fantastic. What kind of creature, what time period and quality of the sample etc.. any help would be greatly appreciated!

I recently aquired this at a local shop in China. I'm assuming it's real (as there are many fakes), because of the weight and feel and the crystalization, where the tooth is broken. I'm not sure how to begin the fossil identification process. If you have any tips about the process of elimination, please let me know, I'm very curious about the date period and of course ID'ing what they would have belonged to. Thanks for your support!

From White River formation South Dakota. Has some appearance of Oreodont but it seems small.

New member, 1st post. Lifelong collector, recently re-enthused after finding this in South Dakota during a hunting trip. Take pity on the new guy and my first attempt at fossil photography. Would love to put a name to this!

Found in western Washington state. Note the premaxillary tooth or tusk structure. Any identification help is appreciated. Thanks.

Hi, 1st time post here, been collecting fossils like ammonites, chrinoids, trilobites etc for a while, but I came across a couple of fossils at a curio shop and was looking for help with ID, the owner of the shop found them near Whitby bay alongside other "ice age" fossils and estimated age at around 10,000BC. There is a large bone, around 13 inches in length and pretty thick and weighty, the best guess he could give me was part of an ox or bison leg, but curious if anyone can shed more light for me, would be interesting to know which bone and which animal The second one is clearly a mandible, he didn't give me any information but by looking appears to have belonged to a wild pig/boar, but not sure as it's not a complete jawbone, only about a 6 inch section and any more help would be great. Apologies for the pictures, had to take them on my phone and the camera isn't brilliant and have a few extras from different angles if people need. Many thanks for any light anyone can shed on them in advance.

I have two associated Hyaenodon horridus mandibles from Nebraska. They puzzled me because they appear to be from an adult but when I removed some matrix is saw gaps for a molar and a tip of tooth peeping out. I looked into it and it seems that the last molar doesn't reupt until age 3-4 so that is roughly the age of this animal. To verify, I asked a good mate to xray it. You can clearly see the tooth roots below the crowns of the teeth and below the gum line (ie embedded into the bone). You can also clearly make out the mandibular canal (long dark line running ventrally (below) the teeth - it's where the major veins, arteries and nerves of the bone run. Great view of millions of years old bone and teeth! Confirms that the teeth are erupting molars and gives me a great idea of the age. Not, quite juvenile, more like subadult.
