Upham and Patterson (2012) values are from an analysis of 12S rRNA, GHR, vWF, and RAG1 for 29 echimyid species; Fabre et al. (2012) values are from their “ALL (IncludeStem)” analyses of APOB, GHR, RBP3, RAG1, vWF, cyt-b, 12S rRNA, and 16S rRNA for 15 echimyid species; Galewski et al. (2005) values are from their analysis of vWF amino acids for 20 echimyid species; and Leite and Patton (2002) values are from their analysis of cyt-b, 12S rRNA, and 16S rRNA for 14 echimyid species, using a hard minimum constraint of 7.9 ± 1.1 Ma on the Thrichomys lineage (by comparison, the present study used a soft minimum on the same lineage).

* Divergence time not reported in given analysis. ** Only one taxon sampled in given analysis. *** Taxon not sampled in given analysis.

All times are in millions of years and refer to estimated ages (and confidence intervals) of the specified crown groups. Results from this study are from the topology in Figure 4 and Additional file 4.
