A Highly Conservative Method For Specimen Dissection


This page is rated "A" for "Anatomical" and "G" for "Graphic". By that, I mean it's a little Silence of the Lambs


My MS thesis, Examining morphological variation of the hyoid apparatus in monitor lizards, necessitated an unconventional museum practice. I needed to see the hyoid within the body (in-situ). I looked at cleared and stained, digitally scanned and dry (osteological) specimens. Those preparation types were informative but insufficient overall. I needed a bigger, more diverse sample from the museum collections.

Dissection was the answer.


One Problem : Curatorial staff become uncomfortable when researchers want to dissect. Understandable! Taking a scalpel to an animal results in the permanent destruction of a piece of history. Not something that we want. On the other hand, specimens exist to be utilized by researchers. Soooo....


Solution : Innovate a highly conservative approach to specimen dissection. Implement strategies that taxidermists use to disguise their incisions. 


Outcome : Post-data collection, the specimens were stabilized and returned to their collections. I was allowed to dissect in four museums and so far as I could tell, nobody got mad at me.


I had incentive to do a good job because; 1) it protected my dissection privileges and kept collection staff happy. If the staff are unhappy, I'm unhappy. 2) the moment that I publish my data, these become voucher specimens. Their values will increase. I DO want my steps to be re-traceable so I do NOT want the specimens to fall apart. I want them to last. So, a conservative approach benefits all.


My approach is illustrated in the filmstrip below. For long, boring, written instructions on how its done, see my PDF doc.

Good luck! If you're into this kind of thing. If you're not, I recommend navigating to another page quickly before you become thoroughly weirded out.
