Dear Pauline,
If you have complete skulls you should be able to separate black
and brown rat. See: Corbet G.B. and Harris S. 1991. The handbook
of British mammals. Oxford: Blackwell, p.249 Fig.8.28.
If you want to write to the list directly you can join by sending the
following message to [log in to unmask]:
Pauline Barber join zooarch (make sure there is no other text in the
body of the email).
Should anybody know of any other criteria to separate the two
species, I think this would be of general interest, so please send it
for information to the list too.
Cheers,
Umberto
