Natural Science Forum / Physics / Optics / October 2006vole bones preparation
I gotten hooked on owl pellets. Yes I know I need a life. Today I was trying a new technique and a vole skull came out almost intact. The brain case is very fragile and any movement causes cracks and fragmentation. Question: I thought about taking a small brush and Elmer white glue and try to cover it. This "should" created a harden surface to prevent anymore cracks. Later if this works I could try and reconstruct the skull case from other specimens, using this a template. . Any suggestions or web site would be appreciated. Thanks in Advance Ed > I gotten hooked on owl pellets. Yes I know I need a life.

Ed: To the extent that paleontological techniques might be applicable, you harden the pellet with an adhesive mixed in with a solvent driver before extraction. PVA glues with water and 5-10% alcohol are one formula. Other formulae involve various adhesives like the Butvar series, Vinac and Glyptal combined with solvent drivers like toluene or acetone. The idea is to harden the area of interest and extract the target item either by using mechanical means alone or in combination with focused application of the original solvent to weaken the binding of matrix materials around your item of interest. That said, you would do well both to search under +"paleontological techniques" +consolidation and under +("preparation of scat" OR "scat is prepared" OR "scat is treated"), among other variations. Try vivisimo.com for its clustered search methodology. I think a little looking will quickly pay off. Regards, Edward Hennessey |
