A Simatherium such as the Langebaanweg species could be ancestral to the Laetoli one. Nearly all its differences from the Laetoli examples can be thought of as more primitive, and this contrasts with the comparisons previously made with other bovines. It is interesting that at Langebaanweg the horn-core inser- tions are more inclined. Either this character is primitive for the genus or it could be an indication of regional specialization at an early time level.
