In November-December 2021, an international team of scientists worked with the Seychelles Islands Foundation (SIF) to uncover fossils and explore the atoll's history on Aldabra Atoll. The mission followed the 2016 finding of ancient bones from giant tortoises and huge crocodiles. During this month on the atoll, the scientist uncovered hundreds of kilos of limestone with embedded fossil bones, including those of tortoises and crocodiles, as well as various bird and reptile species.

They aimed to safely carry those items to Europe, where the bones could be removed from the hard limestone in a laboratory and thoroughly analysed. Hunt Deltel aided SIF in this expedition by shipping the fossils to Zurich via Express Logistics. The experts will research the bones for several years before returning them to Seychelles, where they will hopefully be displayed in the Seychelles Natural History Museum.

Denis Hansen believes that learning the past can help us in the future. Aside from the pure scientific significance of unravelling Aldabra's past, developing a more thorough picture of the identity and dynamics of Aldabra's creatures over the previous few hundred thousand years is critical for future conservation and restoration management measures. Furthermore, studying the effects of climate change on Aldabra is becoming an increasingly crucial concern for SIF. Paleoecological data can assist scientists in comprehending previous climate change effects, particularly sea level variations, and hence help more precisely anticipate the ecosystem-level repercussions of continuing climate change.
