America once had native horses, camels, mammoths, and other large animals that were extinct before Europeans arrived.

I wonder who ate them all.

I believe horses were first introduced by the Spanish.

There is a surprising amount of information indicating that the "indigenous" predation was a significant factor in the Quaternary Extinctions (time when over 300 species of Ice Age megafauna went extinct).

Sites are numerous where bones have weapons imbedded in them, where bones were burned and then split for the marrow, etc.
PETA freaks wouldn't have liked the appetitive behavior of the "indigenous".
