There are these on Dugong dugon, may be of some (limited) use!
There are also a few photos of the archaeological dugong remains from Akab Island in the Antiquity paper: http://antiquity.ac.uk/ant/083/ant0830696.htm
All the best, Hannah

There is a legendary monograph on sirenian morphology including a lot of osteology, written in the 1970s by an author named Kaiser or something close to that. I say legendary because this is zooarch oral tradition. I have never actually seen a copy nor encountered anyone who has! But if someone out there in Zooarchland has a copy, I'm sure Jacqui and I would not be the only ones who would welcome a copy.
