Abstract There is overwhelming molecular support for the monophyly of a supra‐ordinal clade of living African placental mammals, the Afrotheria, but there is not a single unequivocal morphological synapomorphy for this group. We conducted a survey of thoraco‐lumbar vertebral numbers across mammals, based on the examination of specimens representing 86 living and 12 fossil species and a thorough review of the anatomical literature. A total of 19 thoraco‐lumbar vertebrae is plesiomorphic for… Expand
