When was the specimen OH24 discovered?

The specimen OH24, which is a well-known fossil of an early hominin from the species Australopithecus boisei, was discovered in 1968. This specimen was part of a collection of fossils found at Olduvai Gorge in Tanzania by the Leakey family, who were significant contributors to paleoanthropology. The discovery of OH24 provided valuable insights into human evolution, particularly regarding the physical characteristics and possible behaviors of early hominins. This timeline is significant as it highlights the ongoing research and discoveries in the field of anthropology during the mid-20th century, a period that saw numerous important finds that shaped our understanding of human ancestry.
