Prehistoric Rock Art discovered in the Amazon

21. The article does not agree with your assessment.

It quotes Jose Iriarte, professor of archaeology at Exeter and expert on the Amazon and pre-Columbian history:

"The pictures are so natural and so well made that we have few doubts that you're looking at a horse, for example. The ice age horse had a wild, heavy face. It's so detailed, we can even see the horse hair."

That would be a hippidion, I believe, which went extinct in the Americas about 12,000 years ago. The article also mentions the giant sloth, paleollama, and ancient plant life, before the region was a rainforest. It also says there are tens of thousands of paintings, over a distance of 8 miles, that will take "generations" to study.

I'm inclined to accept their expertise.
