''Allodesmus'' is an extinct genus of pinniped from the Miocene and related to the genus ''Desmatophoca''. It measured about long and weighed . ''Allodesmus'' had the specific anatomical features found in modern polygynous pinnipeds: sexual dimorphism, strong canines for fights between bulls and teeth with well-defined growth zones, a result from periodic fasting (in order to defend their harem, males would not take to the sea to feed during the breeding season). == References == * After the Dinosaurs: The Age of Mammals (Life of the Past) by Donald R.
