Comparison of phylogenetic trees and of the three hypotheses of hyaenodont origin and dispersals with focus on the Sinopinae and Proviverrinae. A. African origin with subsequent dispersals of the Sinopinae and Proviverrinae into Europe, and of the Sinopinae from Europe to North America. B. Asian origin with subsequent dispersals of Sinopinae and Proviverrinae into Europe, and of Tinerhodon from Europe to Africa
