What type of large, four-legged animal with medium-sized ears is it that is standing next to a man as depicted on the Chitzen-Itza stone carving commonly called "The Chitzen-Itza Horse"?
Most PC archeologists reject the conclusion it is actually a horse, but even llamas were not generally as far north as Yucatan. Maybe a Saint Bernard?
Also, the Mayan Rain God Chac, depicted with a large curling nose, most resembles an elephant, but again, PC archeologists reject that conclusion as well. These two PC rejections survive despite the fact that pre-columbian bones of horses and elephants have been discovered on the North American continent at various locations.
Could it be that American "Man" has domesticated/associated with animals the PC traditionalists don't want to acknowledge?
Not credible, I'm sorry.
