If man made his mark in Penha Garcia, the same is true of nature. One of the greatest treasures of the town is in quartzite rocks 490 million years. At the time when all continents were united around the South Pole, the seas were inhabited by invertebrate organisms that moved in sandy-clay substrates, leaving marks. To these brands, which were preserved in sedimentary rocks and are visible today in Penha Garcia, the people call the painted snakes and trace fossils scientists. And if the Penha Garcia of people have come long before him, researchers continue to study them, considering them an important contribution to the scientific knowledge of a past millions of years.
