摘要
Dental remains of the earliest known helohyid artiodactyl are described from the Late Eocene of Krabi in South Thailand. This new form, Progenitohyus thailandicus n.g. n.sp., is distinct from Gobiohyus, a specialized genus from the Middle Eocene of Mongolia, and it displays strong affinities with the primitive anthracotheriid Siamotherium krabiense from Krabi. Both Thai species certainly testify to an ancestor-descendant relationship, but an even earlier differentiation of Helohyidae and Anthracotheriidae should be searched for in the Middle Eocene or even earlier.
