Phylogenomics of extant Crinoidea (Echinodermata) reveals extensive morphological homoplasies and a Permian origin
Abstract. Crinoids have Ordovician origins and are unique among living echinoderms in their attachment to the substrate. Most diversity is within Comatulid

When I started my PhD ~10 years ago, only 2/5 echinoderm groups (the star-shaped sea stars and brittle stars) had genome-scale phylogenetic datasets. I am proud to say that the quest to complete the clade is now over
