This order comprises the following families: 

  • Heliornithidae (Sungrebe, Finfoots)
  • Sarothruridae (Flufftails, Wood Rails)
  • Rallidae (Rail)

Timetree of Gruiformes according to Prum et al. (2015), Boast et al. (2019) and Kuhl et al. (2021), with the distribution of each taxon being indicated by the colour-code used throughout this website (see Distribution code).  Note, however, that Prum et al. (2015) and Kuhl et al. (2021) didn't treat any species of Sarothruridae. 

Timetree of Rallidae according to Garcia-R. et al. (2020, 2021), with the distribution of each taxon being indicated by the colour-code used throughout this website (see Distribution code).
