Analysis of paleoecology has developed over the years to include methods that are essentially taxon free (i.e., they measure ecological adaptations on skeletal remains without needing to know the taxon).
The variables measured for include adaptation to diet, size and locomotion. Dietary proxies include stable isotope analysis, microwear and mesowear, as well as cranial and mandibular measurements. Locomotion is measured using 2D and 3D morphometrics. Size is measured using linear correlation with 2D measurements of bone and teeth.
