Marissa J. Betts is a Postdoctoral Fellow at the University of New England, Armidale, Australia. She completed a BSc (Hons) in palaeobiology at Macquarie University in 2012 in which she examined the relationship between early Cambrian shelly fossils and archaeocyath bioherms in the Arrowie Basin, South Australia. She completed a PhD at Macquarie University in 2016 researching the application of early Cambrian shelly taxa as biostratigraphic tools, and their utility for regional and global correlation. Ongoing work includes complementing the biostratigraphic studies with high resolution chemostratigraphic data and investigations into the palaeobiology and functional morphology of early Cambrian taxa.
