Stegotetrabelodon syrticus Archaeopteryx Hippotragus leucophaeus is an extinctDuring the late Miocene and early Pliocene, African ecosystems underwent significant ecological and faunal transitions, most notably the diversification of proboscideans, a group that includes modern elephants and their extinct ancestors. In this paleobiological context, Stegotetrabelodon syrticus represents an important transitional taxon within elephantine evolution, displaying a combination of primitive and derived morphological characters that
