Current theories regarding dinosaur extinction do ignore the smaller
species that survived the extinction. IMHO I think that the reason why
they suvived is a question of size. When you look at the species that
perished in the K-T extinction, it appears that every species the size of a
housecat and larger perished; their larger bodies requiring more food than
their smaller counterparts. This seems to be the biggest point for the
If the same thing were to happen today (killing off all animals larger than
a cat), there would have to be extremely restrictive environmental
conditions. Almost requiring a cosmic zap.
GEOLOGISTS ARE FUN TO BE WITH BECAUSE THEY'RE VERY GNIESS
