Why this life matters

Her work shows how a find gains scientific value through its position, documentation and preservation.

Timeline

Key moments

  1. Rusinga Island

    Leakey recovers a fossil ape skull in Kenya.

  2. Olduvai cranium

    Leakey finds OH 5.

  3. Laetoli excavations

    The team exposes and records more of the trackway.

Archaeology before the famous finds

Mary Douglas Nicol spent part of her childhood traveling in Europe, where visits to prehistoric sites stimulated her interest in archaeology. Drawing and recording were practical ways to participate in the subject. She later worked in East Africa with Louis Leakey. Her career crossed archaeology and palaeontology, since the people working at a site needed to record artifacts, sediments and fossil animals as well as the rare remains they hoped to find.

Fossils collected in different settings

A fossil ape skull recovered on Rusinga Island in 1948 became an important early result. The setting was different from Olduvai Gorge in Tanzania, where Leakey discovered the cranium now catalogued as OH 5 in 1959. That cranium is associated with several scientific names in different publications. The catalogue makes it possible to follow a single find through changes in classification while still crediting the person who found it.

Evidence left by a moving animal

At Laetoli, the team moved from studying animal tracks to investigating preserved hominin impressions. Unlike a bone, a footprint records a short episode of contact with the ground. A sequence can preserve relative positions and aspects of locomotion. The excavations in 1978 and 1979 exposed more of the trail, and Leakey and geologist Richard Hay published their report in 1979.

Recording was part of preservation

The trackwayโ€™s research history continued after the excavation. Photography and casts made details available beyond the site, while covering the surface protected it from direct exposure. The later conservation program dealt with changes that had taken place under the cover. The records of this work help explain why uncovering a find is only one part of its long scientific life.
