Wighart v. Koenigswald is a paleontologist and professor emeritus at the University of Bonn, Germany. He discovered the complexity of the mammalian enamel differentiating between crystallites, prisms enamel types, and schmelzmuster. He and his various PhD students investigated the enamel in various mammalian groups and tested their systematic significance. Additionally he uses the wear facets to reconstruct the pattern of mastication in mammalian dentitions.
