Sea of the North. As earth witnessed this height through a great

the sea. To the south, we likewise know, that elephants,
lions, and hyenas freely stopped by Africa to Spain, Italy and
the island of Crete,<7 > and, accordingly, the Mediterranean Sea

and, as we have already affirmed, one of these that kind also has
survived to our his/her own times.<9>
But we notice again the arrival in Europe of a great number
animals and the difference of kind for first it seems a
inexplicable riddle. However, the key will be found in the
great climatic changes as which we have already mentioned
happening during this age. On the one hand, we find such animals
as the musk-sheep, reindeer and arctic fox, animals which
the natural house is in northern and tall latitudes, where it snows and ice
prevails the most greater part of the year.<10 > Still during this age of theirs they lived in
Southern France and Italy that have had to have far then a

This animal could not live in a country where the cold was
