Stratigraphic record of Early Eocene Hyopsodus and the geometry of mammalian phylogeny

Eocene strata in Wyoming spanning a period of 5 million years record a branching phylogeny which exhibits gradual phyletic evolution, overall size increase with iterative evolution of small species and character divergence following the origin of each new lineage.
