Re: Extinction and other...



if the massive extinction at the end of the mezoic which caused extinction of 
90% of the species populating the earth at that time, it would have effect on a 
global scale. So if you're on a island like you suggested it wouldn't reallt 
matter because the 
effects of the blast would be inmageble (many, many times the hiroshima bomb!)

Classification: Restricted
About hibernation and burrowers. There are real proofs that all surviving 
primitive mammals hibernated? Arboreal proto-primates, like Purgatorius and 
relatives...they hibernated?
It's like all mammals saying: "Oh, there's a meteor destroying our world! Let's 
hibernate!"
But if it's true, there will be a pattern. Hibernating animals usually live on 
high latitudes. So, there would be survivors mainly in N North America, N 
Europe, S South America and Australia. Maybe. (And the polar dinosaurs from 
Australia?)
Maybe I'm wrong, but I think studies about KT faunal transition come mainly 
from North America. There are other places where it can be studied? Where there 
wre  fossil records enough to reach some conclusion? Lower Paleocene in Europe 
is almost unknown,
the same for Africa, Australia, South Asia. Dinosaurs were worldwide. Would any 
kind of disaster destroy all them?  I think some species  of dinosaur would 
survived in some isolated island, like Madagascar.
Madagascar has ever been a striking mystery to me. There's no fossil between 
Cretaceous and Pleistocene. So, we know nothing about it! Lemurs, tenrecs and 
viverrids are descendants of African island-hoppers, but there's no trace of a 
former fauna.
India is alike. No fossil between Cretaceous and Miocene.
