Olivier Testa (born April 1, 1977) is a French cave explorer, known for his discovery of the orange cave-dwelling crocodiles of Gabon, [1] the Iroungou burial cave [2] in Gabon, the discovery of unexpected caves in the volcanic Bamboutos mountains in Cameroon and several discoveries in Haiti. [3] [4] He has led or participated in over 40 caving expeditions in Africa, Asia and in the Caribbean. [5]
Testa was born in Marseille, France, and grew up in the Alps, in Annecy, where he learnt mountain sports.
After obtaining an engineer's degree at École Centrale Paris in 2000, [6] Testa tried different jobs and worked 2 years at French Institute for Research in Computer Science and Automation (INRIA) (Real-Time Scheduling), [7] near Grenoble, France, from 2001 to 2003. Meanwhile, he was an active caver at the La Tronche caving club (FLT). [8] He explored and practiced in many deep caves in Chartreuse Mountains and Vercors Massif, and started cave diving.
Testa discovered Africa volunteering for a 2-year mission in Dschang, Cameroon] with AFVP (the French equivalent of Voluntary Service Overseas) in 2006–2007. [6] He was in charge of coordinating the Route des Chefferies cultural program and the preliminary works on the Musée des Civilisations in Dschang. He then worked in Ituri, DR Congo for a Humanitarian NGO. [6]
Since 2009, he is a full-time cave explorer.
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. [9] 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, [10] and near Mouila in 2018. [11]
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. [12] 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, [13] feeding mainly on bats and cave crickets. [14] Follow-up expeditions took place in 2011, 2015, 2016, 2017. [12]
In 2013, 2015, 2016, Testa and Oslisly conducted speleological research [15] in the area of Lastoursville, known for a couple of caves since early 20th century. [16] 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). [10]
In 2018, Testa and Oslisly discovered the sepulchral Iroungou cave during a speleological expedition in Mouila area. [17] 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. [11] The cave has been excavated by archaeologists in 2019.
In 2010, Testa is a member of the "Ultima Patagonia 2010" expedition on Madre de Dios Island in Chilean Patagonia. [18]
Batouala is a small village in Gabon halfway along the dirt road from Makokou to Mékambo, in the north-eastern province of Ogooué-Ivindo. A 2014 report noted that "pre-electrification" of the Batouala area was underway.
Taï National Park is a national park in Côte d'Ivoire that contains one of the last areas of primary rainforest in West Africa. It was inscribed as a World Heritage Site in 1982 due to the diversity of its flora and fauna. Five mammal species of the Taï National Park are on the Red List of Threatened Species: pygmy hippopotamus, olive colobus monkeys, leopards, chimpanzees, and Jentink's duiker.
Lastoursville or Mandji is a city in east-central Gabon, lying on the Ogooué River, the Trans-Gabon Railway and the N3 road. It was founded as a slave depot named Mandji, renamed Maadiville in 1883 before being named for François Rigail de Lastours in 1886. It grew around palm oil production and as an administrative centre, and soon became a major missionary centre. The town is also known for its caves.
Léon Louis Vaillant was a French zoologist. He is most famous for his work in the areas of herpetology, malacology, and ichthyology.
Ankarana Special Reserve is a protected area in northern Madagascar created in 1956. It is a small, partially vegetated plateau composed of 150-million-year-old middle Jurassic limestone. With an average annual rainfall of about 2,000 millimetres (79 in), the underlying rocks have been eroded to produce caves and feed subterranean rivers—a karst topography. The rugged relief and the dense vegetation have helped protect the region from human intrusion.
The Jeita Grotto is a system of two separate, but interconnected, karstic limestone caves spanning an overall length of nearly 9 kilometres (5.6 mi). The caves are situated in the Nahr al-Kalb river valley within the locality of Jeita, 18 kilometres (11 mi) north of the Lebanese capital Beirut. Though inhabited in prehistoric times, the lower cave was not rediscovered until 1836 by Reverend William Thomson; it can only be visited by boat since it channels an underground river that provides fresh drinking water to more than a million Lebanese.
The dwarf crocodile, also known as the African dwarf crocodile, broad-snouted crocodile or bony crocodile, is an African crocodile that is also the smallest extant (living) species of crocodile.
Cueva de los Tayos is a cave located on the eastern slopes of the Andes mountains in the Morona-Santiago province of Ecuador and became infamous for reportedly having 'golden plates' that contains the history of Mankind. It owes its name to being the home of the native nocturnal birds called Tayos, which live in numerous caves in the Andean jungles of South America. The cave shot up in popularity thanks to the writings of Erich von Däniken and the 1976 BCRA expedition that Neil Armstrong took part in. Despite numerous expeditions, these plates have never been recovered or photographed. The consensus from the archeological community is that the Golden Library was a hoax.
Petropedetes is a genus of frogs in the family Petropedetidae, found in sub-saharan tropical Africa. In 2002, the genus absorbed all three species of the genus Arthroleptides, but they were moved back in 2014. The informally assigned common name for frogs in this genus is torrent frogs.
The French Federation of Speleology, is a French organisation that represents all persons practicing or studying caving and canyoning and promotes the study and conservation of caves.
Panthera onca mesembrina, also known as the Patagonian panther, is an extinct subspecies of jaguar that was endemic to southern Patagonia during the late Pleistocene epoch. It is known from several fragmentary specimens, the first of which found was in 1899 at "Cueva del Milodon" in Chile. These fossils were referred to a new genus and species "Iemish listai" by naturalist Santiago Roth, who thought they might be the bones of the mythological iemisch of Tehuelche folklore. A later expedition recovered more bones, including the skull of a large male that was described in detail by Angel Cabrera in 1934. Cabrera created a new name for the giant felid remains, Panthera onca mesembrina, after realizing that its fossils were near-identical to modern jaguars’. P. onca mesembrina's validity is disputed, with some paleontologists suggesting that it is a synonym of Panthera atrox.
