Pilbara Fat-Tailed Kangaroos: Using Multivariate and Morphometric Analyses to explore Spatial and Stylistic Variability

Abstract

This paper presents an pioneering analysis of a distinctive motif in the engraved corpus of the Pilbara region: the fat-tailed macropod (kangaroo). This approach uses multivariate techniques and face morphometric analysis (FMA) software to explore stylistic variation. Focusing on engraved art (petroglyphs) in Australia’s northwest, this study aims to develop a statistically viable and repeatable approach to exploring stylistic variability by using morphometrics to quantify the significant attributes of these distinctive kangaroo depictions. Integration of multivariate analysis and cutting-edge FMA technology offers an innovative means of exploring the regional dimensions of a deep-time Indigenous artistic tradition. Differing degrees of stylistic homogeneity are interpreted as different signalling intentionality by the artists in different parts of this region. Landscape placement further reinforces how these motifs represent differently inscribing behaviours across the Pilbara: further evidence about identity production and artist intentionality. Distance metrics of the attributes reveal how indigenous knowledge of kangaroo behaviours has been depicted in these iconic Pilbara motifs.
