Extended Data Fig. 1: Cladogram of East African Proboscidea from the last 26 Ma.
From: Fluctuating climate and dietary innovation drove ratcheted evolution of proboscidean dental traits
Deinotheriidae is indicated in red colour, basal stem of Elephantoidea in grey, Mammutidae in brown, Stegodontidae in black and Elephantidae in green. The families shown in blue are often grouped informally as ‘gomphotheres’. Nodes indicate relationships but not precise divergence ages. The cladogram is based on the Proboscidean supertree of Cantalapiedra et al.58. The dashed line from Elephas/Mammuthus to Palaeoloxodon indicates a suggested influence of hybridization into Palaeoloxodon from those lineages (see references in Supplementary Information 1).
