Body Mass Estimation In Amphicyonid Carnivoran Mammals: A Multiple Regression Approach From The Skull And Skeleton, Borja Figueirido, Juan Antonio Perez-Claros, Robert Hunt, Paul Palmqvist

University of Nebraska State Museum: Mammalogy Papers

The body masses of sixteen species of amphicyonids (Mammalia, Carnivora, Amphicyonidae) from the New and Old World were estimated on the basis of 86 osteological variables measured from the craniodental (N = 44) and postcranial (N = 42) skeleton of living species of Canidae and Ursidae. Given the absence of complete and well preserved skeletons of amphicyonids in the fossil record, multiple regression functions were derived separately from measurements taken from the mandible, the cranium and the major limb bones. The accuracy of the regression functions was evaluated using the percentage prediction error and the percentage standard error …
