The origin of P. chromatophora in time according to SSU rRNA lognormal molecular clock.

Tree calibrated under the scheme (a, b, c, d, e.1). Small open red circles indicate calibrations based on fossil record (a, b, c, and d); small open blue circle indicate calibration based on previous estimation (e.1); red full circle, estimated age of P. chromatophora. Notice that the divergence in time of P. brassicae (black open circle) is consistent with the proposed origin in time of forams. Species names in orange: stramenopila; species name in blue and green: rhizaria.
