“Terror Bird” Arrived in North America Before Land Bridge, Study Finds
Phys.org / January 23, 2007

Be afraid. Be very, very . . . Oh, wait, never mind:

A University of Florida-led study has determined that Titanis walleri, a prehistoric 7-foot-tall flightless “terror bird,” arrived in North America from South America long before a land bridge connected the two continents.

The terror bird was carnivorous, weighed about 330 pounds, had powerful feet and a head larger than a man’s.

And was purportedly looking for Colonelius Sandersii.
