Stratigraphic ranges, BEAST calibrations, and section references
Species Fossil Date of 1st occurrence (Ma) Node Calibration (mean, standard deviation, offset) Median (95% interval)
C. natans 5.1-5.3 0.5,1,5.1 6.7 (5.3-16.8)
F. fragum 3.0-5.6 1.1,0.8,3.0 6.0 (3.8 - 17.4)
D. clivosa 4.6-5.9 0.6,1,4.6 6.4 (4.9-17.5)
D. labyrinthiformis 2.9-3.1 0.7,1,2.9 4.9 (3.2-17.2)
D. strigosa 4.6-5.9 0.6,1,4.6 6.4 (4.9-17.5)
M. areolata 3.0-5.6 1.1,0.8,3.0* 6.0 (3.8 - 17.4)
M. mayori 2.9-3.1 n/a*

Ranges in fossil dates of first occurrence reflect accuracy of section dating. References for dates can be found in Additional file 5. *Calibration for Manicina is at genus node since species not well supported in phylogeny.
