I was wondering how long it would take to find something like this. And just think...in my Home state, too...;o]

And recently, it has been discovered that a type of horse was native here, but for whatever reason, died out. Probably the same catastrophe that took other animals of that period. Perhaps an ice age. They were only REintroduced by the Spaniards. (Of course, if you read any of Velikovsky's works, most of this is answered.)

As for "native" plants, the ones you mentioned, Cobalt, were common in all the Americas. Maize and peppers are known to have existed in Africa and Middle-Eastern countries as far back as there have been written records.

Quibble. There's no evidence that the horse died out, or that the horse was reintroduced by Coronado's expedition. Evidence would include a post-it note from Coronado, saying, "oh, and we lost a bunch of horses today". Good points regarding PreColumbian plants, and I'd also add the "Cocaine mummies" evidence.

"And recently, it has been discovered that a type of horse was native here, but for whatever reason, died out. "

All the horses in the world are related to the horses of North America. They survived elsewhere but not here.
