[Nhcoll-l] Formaldehyde and bone preservation

[Alexandra Snyder]

My question/comment as well.  The specimens should not be fixed in formalin prior to maceration given the antibacterial properties of formalin/formaldehyde;  the maceration process would be greatly inhibited.  You need those bacteria to help rot the flesh from the bone.  My other comment: I assume you will be removing flesh and organs prior to processing specimens.

Is there any reason to fix tissue prior to maceration?  I can only think of negative consequences to using formalin, like those Dirk enumerated.

Hi everyone,

We will have a number of medium bodied primate carcasses that we plan to macerate in order to preserve the skeletons. We've been told that fixing with formaldehyde prior to maceration can negatively affect the bones.

What are the consequences? Is this an issue for both short and long duration fixation, or just long? Thanks very much.

David
