Phylogenetic and Morphologic Analyses Elucidate Relationships in Paracrinoidea (Echinodermata)

Evolution and Development at the Origin of a Phylum

“…Thus, this tree likely represents a conservative estimate of the amount of homoplasy within echinoderms through the early Paleozoic. The tree was constructed using published phylogenies [62][63][64][65][66][67][68][69][70][71][72][73][74][75][76][77]. Many echinoderm taxa and clades have not been formally examined in a modern phylogenetic context, such that constructing a supertree would exclude a fair number of important taxa.…”
