Klein, 1734
The above cladogram
is a summary phylogenetic
hypothesis of the Echinodermata, based
on David and Mooi (1997), Littlewood et al. (1997), and Sumrall
and Sprinkle (1997). Note that Edrioasteroidae is not a monophyletic group and that
the phylogenetic position of most fossil echinoderms is still
uncertain.
