Do you have NA's or Infs in your beta1 due to the use of log(Skull) and
log(Tusk) in your modeling or did you misspell something?.
If it's not something "obvious" like that, you should probably post on the
r-sig-ecology list instead, where you are more likely to find both the
interest and expertise in this specialized topic. This list is for general
R language questions primarily.
