is possible, but it takes a lot of time and effort. ETOH only (i.e. no
formalin) works much better. Dermestids will even eat those, but
slowly. We even had a cage of dermestids here once upon a time that
seemed to prefer specimens with a little ethanol sprinkled on
top.<o:p></o:p></SPAN></P>

had some luck with formalin-fixed specimens if I soak the skinned specimen in

dry skeleton from formalin-fixed material?<o:p></o:p></SPAN></P></DIV></DIV>

<DIV>
<P class=MsoNormal>Hello all,<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal>Is it possible to make a dry skeletal specimen from
material that has been fixed in formalin? <o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p> </o:p></P></DIV>
<DIV>
<P class=MsoNormal>A research associate here is receiving some shoulder joints
that were dissected out of mammal carcasses. He wants to prepare them as dry
skeletons for his research, however the sender preserved the material in
formalin before sending (apparently following standard veterinary
practice). They may have been in the formalin for a few weeks or a couple
months at most.<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p> </o:p></P></DIV>
<DIV>
<P class=MsoNormal>Is it possible to safely prepare these as dry skeletal
specimens or is the best option to clean any flesh away but preserve the
joints in ethanol? I am concerned that residual formalin will remain in the
bones even if they are soaked extensively in water prior to maceration and
drying. <o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p> </o:p></P></DIV>
<DIV>
<P class=MsoNormal>Thanks for any thoughts and advice.<o:p></o:p></P></DIV>
