COVER Forelimb bones (longest, ~19 cm) and jaw (~8 cm) of a new partial hominoid skeleton from an ~15-million-year-old site at Kipsaramon, Kenya, superimposed on a digital elevation model of western Kenya and eastern Uganda. The skeleton represents a new genus, Equatorius, and will help clarify the origins of the group that includes humans and the living great apes. See page 1382 [Photos: Steven C. Ward]
