Museums that had lost their interest in the subject were revived, classes were taught on the particulars of Amazonian archaeology, and teams of archaeologists were arriving in the Amazon to begin new research. Then, from the middle 1960s through the middle 1980s, the Smithsonian Institution and the Conselho Nacional de Pesquias agreed to implement a program called the Programa Nacional de Pesquias Arqueologicas, which was a major step forward in the attempt to understand the history of the Amazon. More than 1,500 sites were investigated, and grouped into different categories of research. In the 1990s, the research of the Amazon has become less developmentsl, and increaingly focused on individual sites. The stone point dating from 11,200 years ago and pottery nearly as old have only recently been discovered.
Amazonian archaeology has a long way to go before researchers can hang their hats.
An area such as this one, which has been ignored for quite some time, has a lot of catching up to do.
