Unless mammals indulged in 'egg feasts'. I doubt there were any mammals in the
could dig up a dinosaur egg and carry it off while the parents were otherwise
dinosaurs may have had an initial advantage in this hypothetical scenario, but
if their reproductive
success was severely compromised then it would only be a matter of time before
swung back in favour of the mammals.
Look what happens when even small mammals like rats or mice are introduced to
birds have no experience of mammalian carnivores - bird numbers tend to plummet
Introduce a single cat to a small island and it can wipe out an entirely bird
species in short order.
The dinosaurian behavioural repertoir would most likely not have included
to large mammals, so they may have been in a similar situation to that of
modern birds that
evolved on mammal-free islands.
