I understood that in general male animals tend to be larger than female 
animals.  How indicative is the other evidence?  I ask because I've read 
it explained another way.

  The only problem I have with this idea is that there seem to

Perhaps some males lived in different locations than the females, making 
it easier for their remains to become fossilized (females living in 
highlands, possibly with their mates; unmated males roaming more freely, 
or some similar scenario), or maybe it's a preservational fluke.
