Thylacosmilus and Smilodon both have saber teeth, but they do not share an ancestor To get a clearer idea of what Thylacosmilus fangs might have been good for, the team conducted biomechanical studies comparing them to Smilodon. After simulations of skull and tooth performance were run with models of skulls generated from computed tomography, the researchers discovered that the marsupials skull was considerably weaker than that of Smilodon and was not robust enough to support a saber-tooth-style stabbing bite. "But what we can show is there was probably a difference in behaviour between the two species: Thylacosmilus' skull and canines are weaker in a stabbing action than those of Smilodon, but are stronger in a 'pull-back' type of action.
