## Caving expeditions
### Gabon

In 2007, Testa and EEGC team, on an expedition to Gabon, discover in the area of Tchibanga, Nyanga the first cave drawings of the country. Other cave drawings or carvings have been later discovered in other parts of Gabon by Testa and Richard Oslisly, in Lastoursville in 2015 and 2016, and near Mouila in 2018.
In 2010, Testa, with a team led by Oslisly (Shirley, Testa, Sebag, Decaens, Mabicka) went on an expedition in the upstream part of the Fernan Vaz Lagoon, Gabon. In the caves of Abanda, cave-dwelling crocodiles, with a unique orange color, were found and captured by the team. These dwarf crocodiles are trapped in the caves along with 10,000s bats. They live in complete darkness, in liquid guano, feeding mainly on bats and cave crickets. Follow-up expeditions took place in 2011, 2015, 2016, 2017.
In 2013, 2015, 2016, Testa and Oslisly conducted speleological research in the area of Lastoursville, known for a couple of caves since early 20th century. In three expeditions, they explored and surveyed 40 caves in the rainforest surrounding the small town. Among discoveries, new caves (Boukama cave , Missie cave, Moungueke cave), several archeological findings (cave drawings in Koubou cave, carvings in Lipopa cave, some ancient iron currencies in Nzoundou cave, beads and bells in Siyou cave, jasper flints in Youmbidi cave).
In 2018, Testa and Oslisly discovered the sepulchral Iroungou cave during a speleological expedition in Mouila area. Testa rappeled down a newly discovered cave and set foot in a chamber where he counted 29 human skulls and hundreds of human bones. Hundreds of artifacts made of iron, copper and brass were scattered on the ground : hoe-blade currencies, knife currencies, currency bracelets, bells, and other power objects. The cave has been excavated by archaeologists in 2019.

### Chile
