[1][2] Jerimalai has the third oldest findings discovered in Wallacea, after Madjedbebe in mainland Northern Australia and the Laili cave near Manatuto on Timor.

22,000 years ago, during the Last Glacial Maximum, the sea level was 121 m lower than in 2016 and Jerimalai was 3.5 km from the shore.

[1] Tools found in Jerimalai are similar to findings in the Liang Bua cave attributed to Homo floresiensis, who lived on the nearby island of Flores until 50,000 years ago.

[4] The high advancement of fishing technique for the time can be explained by the lack of land animals on Timor in that era.

This would also explain why among the thousands of shell fragments (about 50 kg of material was collected during the excavation) only 268 belong to Nautilus pompilius.

With the exception of an undescribed species of Grus, all the avian remains represent taxa still extant in the present.
