Figure 1From: Phylogeny and chronology of the major lineages of New World hystricognath rodents: insights on the biogeography of the Eocene/Oligocene arrival of mammals in South AmericaTimescale for hystricognath evolution. Statistical support for all nodes is 100% BP, except for the Capromys + Proechimys association, which is supported by 68% BP. Bars on nodes indicate the 95% credibility interval. Letters on nodes indicate the calibration information used.Back to article page
