Louis was so impressed with their finds that he gave them National Geographic money for a month's expedition. They explored in the vicinity of Peninj near the lake, where Richard was in charge of the administrative details. Bored, he returned to Nairobi temporarily, but at that moment, Kamoya Kimeu discovered a fossil of "Australopithecus boisei". A second expedition left Richard feeling that he was being excluded from the most significant part of the operation, the scientific analysis.
