Natural Science Forum / Biology / Paleontology / February 2006Thinb sections of fossil bone and tooth material
I'm working on a small project and need to prepare thin sections of different types of bone and tooth material. Outside my own collection, of mostly Cenozoic material, I've supplemented my research specimens via donations, and from e-Bay purchases. Problem is that I need material with specific location information and identity (I'm a mineralogist, not a paleontologist). While there are excellent specimens that can be purchased, I do not have the resources to purchase and saw up, say a T. rex tooth, so I can make a thin section. Does anyone on the list know of a source (sources) of "discard" grade fossil bones or teeth that I could obtain at a reasonable price? Thanks.

Museums occassionally do this. Hope this helps. George Are there specific localities that you need specimens from? I've gotten rid of most of my fossils, but I have some miscellaneous stuff still around that I would be happy to contribute to a serious project -- e.g. a few very small Cretaceous shark teeth from a bone bed in the Mancos shale near Green River, Utah; a bag of Miocene Shark Tooth Hill material, and such. Is there a minimum size that you can work with, etc? Come to that, I wouldn't mind an excuse to go out and collect a few fossils when the weather warms up, but the nearest sites where I'd stand much chance finding material that might of being of use to you are a six hour drive from Northern Vermont and I'd like to know before I set out that the material (if I find any -- which is far from a certainty) would actually be useful. Hi Don, George, What I really need at this point are some adequately identified Dinosaur teeth and/or bones and any croc material, especially Mesozoic species. I got some teeth off of e-Bay last year of things like Mosasaur, and also got some donated dino teeth. After looking at them, I am uncertain if they are actually what I believed them to be. I have some Hadrosaur teeth that are pretty solidly identified, but I'm not convinced that I have either Mosasaur or Coelophysis teeth. I'm pretty well supplied with shark, ray, fish and most of the Miocene/Pleistocene vertebrates. Several people donated Dinosaur bone fragments, but a lot of them proved to be poorly preserved. I would like to have one long bone from a Dinosaur, any Dinosaur, and a well preserved long bone from a croc that I could make a transverse thin section from. I've written a paper for submission on the optical crystallography of fossil hydroxylapatite, but won't submit it until I can better confirm some of my findings with better fossil material. Since my budget for specimen acquisition is about....well, zero, I have to scrounge around and see what I can find. Thanks for responding to my post.

You will likely have to call quite a few before you find one that has what you need. But it is worth the effort if it results in usable specimens. George |
