Slight correction: the most basal pan-euungulate (or stem-euungulate).
They explicitly define Euungulata as a crown group: "the least
inclusive clade [sic - they clearly mean 'the most recent common
ancestor'] of Tursiops truncatus, Lama glama, and Equus caballus and
all of its descendants". (I'd question the use of a nontraditional
ungulate like Tursiops truncatus as a specifier, but it probably
doesn't matter.)
