Description
Marrellomorphs are the group of early Paleozoic arthropods that get their name from the well-known Burgess Shale fossil Marrella splendens. They have for a long time been considered to be closely related to the trilobites, based on similarities in their gills, but numerous studies have since suggested they are closer related to mandibulate arthropods (crustaceans, insects & myriapods), although their strange appearance means other relationships might still be plausible. Since they have a soft exoskeleton, marellomorphs have a very poor fossil record and so the discovery of any new specimens outside of the Burgess Shale can be incredibly significant. In this interview, we speak to Joe Moysiuk of the University of Toronto and Royal Ontario Museum about his newly described species Tomlinsonus dimitrii.
