I know there are worn or broken but would like any information on them. They are fairly large. I think the two white ones might be from the same animal or age, while the black one is very dense and was possibly much bigger than the remaining piece, but I don't know. They came from a beach near Fort Pierce Florida. You can see the rule for scale. Thanks for any thoughts.

Found this large fossil tooth at the Kaloot beach, The Netherlands while looking for fossil shark teeth. Tried cross referencing it to the local database and I think it might be a European Bison...but I'm not sure. Maybe some of you guys can ID it! It's about 10-12 cm tall (rough estimate), two deep grooves on top. Bottom is hollow. Quite worn, you can see the internal bone structure in several places. Sides are smooth. Would love to hear what you guys think!

By measuring tooth growth rings and bone blood vessels in small Jurassic mammal fossils, scientists determined that small mammals lived for 9 to 14 years back then while similarly sized mammals today would live for 1 to 3 years. https://amp.cnn.com/cnn/2020/10/12/world/mammal-teeth-reptile-intl-scli-scn-gbr/index.html

Just got back from the fossil fair at Sanford Civic Center in central Florida, had a great time and brought back some great specimens. There's quite a variety here, but I have quite specific geographic/geological data for each piece, so I'm excited for some opinions. After some careful deliberation, I've decided to make separate posts for each specimen, as I want to thoroughly inspect each piece rather than half-haphazardly glance over all of them. The tag with this fossil reads exactly: "Osteoborus cyonoides Late Miocene- "Hemphillian Ogallala Group Hemphill Co. Texas 'Coffee Ranch Fauna'" Apparently Osteoborus is a synonymous taxon for Borophagus. How does the tag hold up? Thank you very much for your time, much appreciated. NOTE: ruler is in cm, this tooth is quite small.

Here are pictures from a recent trip to Post Oak Creek in Sherman Texas. Found several shark teeth but all of them broken and most in bad shape. I also found several non-fossilized material. I'm not sure if it is modern or a little older. It is all small. The one with the jaw still has two small teeth incased in it. Also I have no idea what the teeth are that are rounded. One of the pictures is a partial shark tooth still in the matrix.

Small jaw segment with teeth (Ischyromys?) White River Formation
Opabinia Blues posted a topic in Fossil ID
Hello, this is a small jaw segment from the White River Formation (Poleslide Member of the Brule) from Weld County, CO. This is one of a few jaw segments I cannot white identify. It does not look like the Leptomeryx jaw segments that I have collected (and indeed is even too small to fit that genus), and the shape of the teeth to me do not look like they belong to an Artiodactyl of any kind, so my best guess based on picture browsing is Ischyromys but I could be very very wrong here so I appreciate any help. Thanks!

Hello! This is a canine tooth (that has been split in half) that I collected from the White River Formation (I believe Poleslide Member of the Brule) from Weld County, CO. I think it is a carnivore’s canine rather than simply an Oreodont canine just due to its size, but I could be wrong there I suppose. My best guess is Daphoeneus or similar due to its shape, it does not look like Hyaenodon to me, but again, could be totally off there. Pictured is the tooth’s lateral surface, interior (because it was split when I found it) and the “cutting surface.” Thanks!

Found this skull in a cliff in southern Maryland. Was dug out of grey clay in small cliff. Looks to be a Boar skull? Any ideas to the age?Miocene?

Took a very early morning trip to the beach with my daughter this morning and we found some very nice things. Im thinking that the shark teeth are Mako sp? And maybe white shark? Have no clue on the bones. The bigger one might be a partial whale vert? The two smaller ones I can't place at all. From what I have read on the area is that it's Miocene to late pliocene in age, terrestrial and marine species are found on this stretch of beach and further inland. Thanks for everyone's expertise.

Hi everyone, some time ago I got this fossil tooth from a European collector, the only thing the seller was able to tell me is that it was a canine of a carnivore (quite evident) and that it had been found in the most recent sediments of the Linxia basin in the HeZheng area (corresponding to late Pliocene-early Pleistocene age). Intrigued by the fossil, I decided to buy it and find out what animal it was. The first thing to do (in addition to hoping that the seller has given you correct information) is to search for articles regarding the fossil fauna and the ecology of the area where the fossil was found. In my case I found a very interesting article by paleontologist Deng Tao (Character, Age and Ecology of the Hezheng Biota, 2005) who gave me an overall view of the variety of carnivorous mammals that characterize the fossil association. Then we move on to carefully observe the fossil, based on the curvature of the tooth this would seem to be a left upper canine. Another important detail is the presence of evident grooves on the crown of the tooth, this feature suggests that the tooth belongs to a feline. Which felines were present in the fossil fauna of the area? -Panthera palaeosinensis = one of the oldest known species of Panthera, but its relationship to other Pantherinae is still debated -Felis teilhardi = an enigmatic lynx like cat -Lynx shansius (Lynx issiodorensis) = an ancestor of the current lynxes, generally it had larger size and with a more elongated snout -Sivapanthera linxaensis (Acinonyx pardinensis) = ancestor of today's cheetahs, it could reach much larger dimensions. Then we proceed by exclusion, the tooth is too slender to be a tooth from Pantherinae and also too big (62+ mm) to be Felis teilhardi's. There are therefore two options, Lynx shansius and Sivapanthera linxaensis, here the analysis becomes more complex because it is necessary to obtain precise measurements of the tooth. Therefore, the length and width of the tooth (mediolateral breadth and anteroposterior length) are obtained. The height is not important because it can be compromised by wearing or possible fractures. Using a digital caliber, I obtained a length of 12.2 mm and a width of 10.1 mm (the measurements are probably inferior than the real dimensions because the presence of the matrix and the skull did not allow a correct estimation. Probably the tooth is larger by 1-2 mm). Comparing the measurements obtained with those reported in numerous articles, we can observed that the dimensions of the tooth are slightly greater than those of a large specimen of Lynx shansius while they fall within the size range (very close to the lower limit, see graph) of Sivapanthera linxaensis. To conclude, considering the underestimation of the measures, either it is a large lynx (unlikely hypothesis due to the lack of wear on the tooth) or it is a young specimen of Sivapanthera linxaensis. Thanks for making it this far, I hope this little recognition exercise of mine can serve as a little guide on how to go about trying to identify a fossil. Clearly, if someone has a different hypothesis or a different theory, they can explain it.

Anyone know what this is from. Found under a bridge on the Smokyhill River

White River Formation small incisors - Rodent? Lagomorph?
Opabinia Blues posted a topic in Fossil ID
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!

I found this chunky fossil this morning at Myrtle Beach. I would love to think its mammal associated, but I'm not sure it's not just a mollusk fossil. I may learn more by cleaning the crusty ocean stuff off.. I don't think it's a cast based on the grain in the broken cross section. Any help would be appreciated.

Not a lot of information here. The area we are hunting generally has small shark teeth, Megalodons, a very few Great Whites, plus marine mammal teeth, verts, etc. There is an occasional land mammal identification, such as Gomphothere. I generally think middle to late Miocene. This is not my find. I am trying to Identify for a friend. My immediate reaction was not whale because I can not detect any horizontal banding and I should see it... Also I have not seen enamel caps on whale like this. I thought Dolphin, but even now, I do not find that convincing. All comments appreciated.

Here is a small tooth found on a beach near Jensen Florida. The crown length is about 7/16 inch or 1.2 cm. It is an isolated beach find. Thanks for your help.

I haven’t had much luck getting these larger bones identified in the past but this one is a little more complete so I am hoping for at least an ID on what part of the body this came from. Found in North Central Nebraska@Harry Pristis

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.

I think this is a premolar. I’m thinking camel, but maybe bison?

Another mysterious bone found near bison bones.

Hey guys! This hunt was on more than a month ago, on the 18th of July, but I haven't had time to make a trip report till today. Better late than never! In late June I invited my good friend Tijn ( @Hunter0811) to come hunt with me at the Zandmotor, and then come to my place to see my whole collection, and we had a great time talking about all things fossil-related. That evening he told me about a new location he had discovered near his house in the east of the Netherlands which also had Ice Age mammal bones, and so we made plans to meet up again soon, but this time over there, so that we could check this new place out together. He picked me up at the train station and we biked to the place. The weather was nice, although maybe just a bit too warm, but sunny and good for fossil hunting. We had to cross a small field with cows to get to the place after parking our bikes, and they were curious to see what we were doing so they approached us to say hi. The site is near a village called Lathum. It's quite literally a big pile of rocks: gravel with lots of erratic stones, all dredged from the bottom of a nearby pond. The hunting there consists of just looking in between the stones.

Questions about the eocene primate Adapis & the Ludian stage
ziggycardon posted a topic in Questions & Answers
Hi everyone. I just ordered a cast of a Adapis parisiensis to add to my Eocene display. But after searching for some info on Adapis I have learned that they are apparently extensively studied, but hardly any of the information is available on the internet. So I was wondering if anyone here could help me narrow down some of the very sparse information that is available. I have learned that they are found in the Quercy Phosphorites Formation and in the Paris Basin. But especially on the case of the Paris Basin I really can't find anything on the exact locations where fossils of these early primates were found. Regarding the age of these fossils, I have found that they are from the Ludian stage, which is a European stage that falls in the Priabonian. I know the Priabonian lasted from 37,8 mya to 33,9 mya, but I can't seem to narrow down the exact age of the Ludian. I hope some of you might be able to help me out with some of these questions. Thank you in advance! -
Found in south central South Dakota. Miocene. Assuming this is from some kind of small mammal but not sure. Thanks @Harry Pristis

Recovered a reddish brown, dense, solid fossil yesterday. Flat spot 40mm x 40mm. Widest part is 75mm x 45mm, x 55mm high. Found in Pleistocene material. I'm guessing it is part of a vertebrae/spinal column. Looked for comparative pics in galleries... was unsuccessful. Thank you in advance for ID assistance. Regards, Michael 40mm x 40mm squared area

Hi everyone, I am a very inexperienced fossil collector. I found this claw in my driveway among the gravel. I live near Austin, TX but I’m unsure where the gravel originated. Any ideas?
