As far as I know rhinoceros, lion and elephant are traditionally found south of the equator in a land called Africa, a very long way south of Kent, England. Considering we are talking about 420,000BCE, we cannot use Rome as an excuse, or any other "modern" civilization.
Elephant I can handle, but how did rhinoceros and lion bones find their way so very far north?
They walked. It was warmer then.
I dunno about rhinos, but lions only became extinct in England fairly recently from what I am given to understand. Bears as well, I believe.
“Elephant I can handle, but how did rhinoceros and lion bones find their way so very far north?”
One step after another.
They were purchased at Trader Joe’s?
The same way the elephants did. They walked in with the rest of the critter before sea levels rose and inundated the Channel.
The climate has changed. Weird, eh? Velikovsky discusses this in “Earth in Upheaval”.
