Phylogenetic analysis of cytochrome c oxidase I sequences to determine higher-level relationships within the coleoid cephalopods

open access: yes, 1999
Until recently, the higher-level phylogenetic relationships of coleoid cephalopods have remained unclear. A thorough knowledge of the higher-level phylogeny of the group has been limited by the paucity of paleontological data for this poorly-fossilized ...
