This file contains the consensus tree inferred on plastid markers by BEAST with the topology fixed. External calibration only was used. Each time unit corresponds to 20 million years.
MCMCTREE in PAML [19] was used with the GTR+Γ5 model. Shape and scale parameters, α and β, in the gamma prior for parameter σ2 were 1.0 and 10.0, respectively. 95% highest posterior density (HPD) is s
Phylogenetic estimation of evolutionary timescales has become routine in biology, forming the basis of a wide range of evolutionary and ecological studies. However, there are various sources of bias t
Echinoids are key components of modern marine ecosystems. Despite a remarkable fossil record, the emergence of their crown group is documented by few specimens of unclear affinities, rendering their e
