The tree is rooted considering the Protoopalina sequences at the basal position according to the results obtained in the phylogenetic analysis of the SSU rDNA sequences. New sequences are noted in bold.

Three sets of calibrations including a total of seven time points were combined to obtain the TimeTree (set A* 'sequence evolution'* included three calibration points with uniform distributions; set B* 'host class constraints'* included two maximum time calibration points; and set C* 'host family constraints'* included two maximum time calibration points; see main text for further details); diamonds indicate calibration points included within the Opalinata subtree. Divergence time estimates and their 95% credibility intervals (magenta bars) are indicated in each node. Images showing the evolution of continents are from Scotese (2016).
