In Europe, "Megantereon" may have preyed on larger artiodactyls, horses or the young of rhinos and elephants. Despite its size, "Megantereon" would have also likely been scansorial and therefore able to climb trees, like the earlier "Promegantereon" (thought to be its ancestor), and unlike the later "Smilodon", which is believed to have spent its time on the ground. In addition to this, "Megantereon" had relatively small carnassial teeth, indicating that once making a kill, it would have eaten its prey at a leisurely pace, either hidden deep in bushes or up in trees away from potential rivals. This indicates a similarity in lifestyle with modern leopards in that it was probably solitary.
