Mr Graham Medlin

Honorary Research Associate Mammals Section working on the Subfossils Collection

+61 8 8207 7462 (Mon and Tue only from 10.30am to 6.00pm)


Graham started working with subfossils in 1976 after finding bones in caves at Chambers Gorge while on a field trip with students from Mawson High School.  He worked on a grant in the Mammal Section of the South Australian Museum, during the period 1988–1989, to identify the remains of the small mammals found in caves at Chambers Gorge between 1976 and 1988.  Graham was appointed as an Honorary Research Associate in 1991.  After retiring from teaching in 1995, he has allocated two days a week to continue with the analysis of owl pellets from field surveys (with the help of volunteers) and to document the pre-European distribution of small mammals (including extinct species) from remains found in old owl roosts.


Research Interests  

Mammal survey work with the Mammal Club of the Field Naturalists Society of South Australia. (More than 35 years experience with this group.)

Analysis of Barn Owl pellets with volunteers at the South Australian Museum, to study the small mammal, bird and reptile ecology of the area around the owl’s hunting range.

Study of old bones (including extinct species) and scats from caves and sinkholes to determine the distribution of small mammals before European occupation.

Study of the past distribution of stick-nest rats within South Australia, by mapping the distribution of their nests and middens.

Analysing bat calls recorded by Anabat to determine the species of bats present during field surveys.
