[1][2] Site G1 is a dune that rises from the lake basin to an elevation of 56.035 metres (183.84 ft) above sea level and extends from east to west.

Phase II dates from 7700-6200 BCE and is characterized by a wet climate and the first evidence of occupation by a fisher-gatherer group known as the Kiffians.

[4] The site was discovered in 2000 by a team led by University of Chicago paleontologist and geologist Paul Sereno, whose previous expeditions to the region had uncovered numerous fossils, including those of the formerly unknown dinosaur Nigersaurus and the crocodylomorph Sarcosuchus.

Discovered by team photographer Mike Hettwer on 13 October 2000, the sheer size and scope of the find, including traces of pottery, human remains and quantities of aquatic-environment animal bones, suggested the site dated to the early- to mid-Holocene, or "Green Sahara" period (7500–3500 BCE).

These archaeologists discovered that Gobero had been almost continually inhabited for 5000 years, beginning roughly from 8000 BCE onwards when the area fronted a large lake.

[1] They were heavily muscled hunter-fishers, they left a distinctive pottery with wavy lines and probably remained in the region until around 6000 BCE.

[6] Artifacts associated with this occupation at the Gobero site include microliths, bone harpoons and hooks, dotted wavy-line pottery, and zigzag impressed motifs.

Earlier burials, usually those associated with the early occupation, have bones that are very dark in color which was most likely caused by their submersion when the lake levels rose.

[1] Some of the remains uncovered at the area were decorated with jewelry, including a young girl wearing a bracelet made from the tusk of a hippo, and a man buried with the carapace of a turtle.

[1] They were buried with four hollow based points, and there was pollen evidence found at the probable family burial, suggesting that flowers decorated the grave.
