better tasting meat before they move into the large size niche again.>>
But really, doesnt the sound of a free range elephant for dinner make your

Ummmm....if you look at all extant mammals, they follow the trend that as
body size increases, litter size and frequency decreases. Thus, I question
whether or not it is physiologically possible for a large mammal to have a
large litter. The real advantage that archosaurs have is when environmental
pressures on a population rear their head. Because of the large
reproductive capacity of large archosaurs, they can rebound much faster than
a large mammal.
