Length and mass estimates for small Australian ornithopod femora. Incomplete lengths estimated via linear regression. Masses estimated with MASSTIMATE49,50 and developmental mass extrapolation (DME), based on Erickson and Tumanova51. Ages estimated via linear regression. Estimates expressed as point estimates followed by 95% prediction intervals in parentheses.
