hafa adai I recently purchased a flat of fossils from a guy I've been buying from in Indonesia (I know a guy... LOL). The ID card with this one said "rhinoceros", Miocene from Java, Indonesia. I have only ever seen rhino molars from there, which this is clearly not. Internet searches for rhino incisors however, yield teeth which are more tusk-like. I'm not really familiar with rhino dentition, so I thought I would appeal for assistance. Is it rhinoceras? thanks!

Hi all, I was recently gifted a lovely fossil from a friend. He told me it comes from a reliable digger from Sangiran and it is a rhino horn. However, I have my doubts Rhino horns as I understand, are made of keratin which means they do not fossilize easily. Also, this fossil here is almost surely a bone. My friend tells me it is permineralized keratin but I am not sure if I agree with that. While there are indeed lines that flow from the base to the tip, I can't tell if they are carved or not My friend mentioned this is a river find, hence the dark coloration. I rubbed it with acetone and revealed a different color underneath. I am 95% sure this is not wood however as there are no wood grains and the weight is more consistent with bone What leads me to the conclusion that this is a real bone and not wood is the cross section. There is actual bone structure here So, what is this "horn" exactly? My guess right now is that it is an actual bone (judging from the base) that was carved into the shape of a horn. There is a honeycomb pattern which you can see on the base. Traces of this pattern can be seen exposed by acetone. Perhaps most of the honeycomb surface pattern was destroyed by carving? Anyway, I could be totally wrong. Maybe this is indeed a true fossil rhino horn and I am just over-paranoid. I would like your thoughts please, thank you

hello folks, I recently acquired a series of 3 teeth identified by the dealer as belonging to Coelondonta antiquitatis (woolly rhino) from 'Russia' (whatever that means). The teeth are certainly from the rhino family (that's as close as I can personally get), but these particular teeth are huge, t least twice the size of any other woolly rhino (or Teleoceras sp. ) teeth that I have (sample size about 20), or any scaled photos of woolly rhino teeth and jaws with teeth that I've found online (note: lots of photos available online, few with scale, alas). I've include two photos below showing the teeth, and a tape measure for scale. Two additional photos follow that include a woolly rhino jaw with teeth and a separate tooth for comparison to these three It got me wondering if these aren't from a woolly rhino but another member of the family?. In scanning the Asiatic rhino family tree, Elasmotherium sp. (Pleistocene) and Paraceratherium sp. (Oligocene) are the only two that exhibit a notable size difference from ol' Woolly. Unfortunately, there are maddeningly few images of teeth or jaws from these two animals, and nothing with scale that I can find. Thoughts? Any references to recommend? thanks in advance!
