Suzanne Duigan

Suzanne Lawless Duigan (7 July 1924 – 1993) was an Australian paleobotanist who specialised in fossil pollen (palynology). She collaborated with fellow botanist Isabel Cookson extensively on Paleogene brown coal deposits in Victoria. She pioneered studies in south east Australian coal measures as she considered micro- and macrofossils of the region in terms of their relationships to living plant species and families and their ecologies.

Early life and education

Duigan was born in

Duigan became a lecturer in botany at Melbourne University upon her return and specialised in fossil pollen (palynology).^[4] She collaborated with fellow botanist Isabel Cookson extensively on Paleogene brown coal deposits in Victoria. Among taxa she described with Cookson were the early Paleogene proteaceae genera Banksieaephyllum and Banksieaeidites,^[5] as well as Araucaria lignitici from the brown coal beds at Yallourn and Agathis parwanensis from Bacchus Marsh.^[6] Duigan took a novel approach in considering micro- and macrofossils of the region in terms of their relationships to living plant species and families and their ecologies. She concluded that the dominant vegetation of Paleogene southeastern Australia were Nothofagus, Agathis and members of the laurel family Lauraceae.^[7]

Later life

In later life she learned to fly, gaining her private pilot's licence on 6 November 1970. She piloted a Cessna 150 and a Piper 140, often visiting her brother in Flinders Island in Bass Strait in the latter.^[2]
