Parsimony phylogenetic hypothesis of the exceptional eastern North American coelacanth sample. a Strict consensus topology resulting from the parsimony analysis with YPM VPPU 14,955 removed, with b equally most parsimonious trees showing recovery of a clade with striated opercles (highlighted to match color in Fig. 1).
