Behavioural adaptations are often invoked in a variety of evolutionary hypotheses; however, few methods to quantitatively compare fossil behaviour exist. Movement paths, such as trails and trackways, are well-studied in extant-organism research where they are discretized and mathematically analyzed for behavioural strategies and trends.
