Discovery of new ruminant dental remains from the Middle Eocene Pondaung Formation (Myanmar): reassessment of the phylogenetic position of Indomeryx

Two new species of Indomeryx are described from the Late Middle Eocene Pond aung Formation, central Myanmar. These two species differ from I. cotteri b y their more primitive dental features, thus challenging the inclusion of I ndomeryx in the new Pecora family Prodremotheridae. Despite poor knowledge of this genus, we rather suggest a basal position within ruminantia, close to Archaeomeryx with which it displays several affinities.
