The use of humerus distal trochlea circumference as a body mass predictor for carnivores is explored. Trochlea circumference is found to be highly correlated with body mass carnivores, (_rư_=0.952, SEE=0.136, p<0001, n=92). Scaling appears to be uniform throughout the order Carnivora, regardless of foot posture. Some degree of differential scaling between carnivore families and between animals of large and small size cannot be ruled out , but this result is inconclusive. A predictive model that allows mass predictions for a broad range of carnivores with a minimum of assumptions is presented. Detransformation bias is corrected by a Maximum Likelihood Estimate. Body mass for eight extinct carnivore species are calculated and these generally conform to earlier mass predictions. |
