"Occasional finds from earlier years and reconnaissance works since 2005 have brought to our knowledge numerous diverse and interesting archaeological monuments in this part of Amapá.
"Until late 2005 here have been found 20 megalithic structures, 8 burial caves as well as sites of ancient villages (some on artificial mounds), burials and votive deposits of ceramics at hilltops - in total 55 archaeological sites."
"Here should be noted that not all are convinced that AP-CA-18 has something in common with archaeoastronomy. After all - 127 blocks of granite may have lots of interesting coincidences created without intent."

Just 1 stone out of so many sites seems to be an archaeoastronomical stretch of the imagination.
Something is not right. This message is just to keep things from messing up down the road
