Although originally considered a chelicerate-like arthropod, these affinities were dismissed based primarily on interpretations of the anterior appendages and hypotheses which considered the megacheirans (‘great-appendage’ arthropods) as putative ancestors of chelicerates. The similarities between megacheirans and… Expand
