^**Martin J. Head is Distinguished Professor of Earth Sciences at Brock University. His interests are in late Cenozoic marine palynology, and particularly the late Neogene–Quaternary record of dinoflagellate cysts and acritarchs, including their morphology, taxonomy and nomenclature. He is past Chair of the Nomenclature Committee for Fossils (2010–2024), and a voting member of the General Committee (2024–2029). He is also involved in formal chronostratigraphy, especially that of the Quaternary System, including conceptualizing and defining the Anthropocene as a new epoch. He is a former President of AASP – The Palynological Society and of the Canadian Association of Palynologists.
^***Julia Gravendyck is a palynologist and botanist at the University of Bonn (Germany). She completed her PhD (2021) at the Freie Universität Berlin in cooperation with the University of Oslo. As of 2022, she has been a lecturer on systematic botany at the University of Bonn. Her current research focus encompasses Mesozoic paleobotany and palynology, taxonomy and nomenclature, vegetation dynamics in the context of environmental stress, and the appearance and evolution of the earliest angiosperms. She is one of the 18 Editorial Committee members of the Madrid Code. Photo: Simon Sommerfeld, University of Bonn.
^****Patrick S. Herendeen is a paleobotanist and plant systematist at the Chicago Botanic Garden. He completed his PhD at Indiana University in 1990. He is currently working on Early Cretaceous and Late Jurassic fossil plants from Mongolia and Inner Mongolia, China. He also works on living and fossil members of the legume family. He currently serves as Secretary of the Nomenclature Committee for Fossils, as Past President of the International Association for Plant Taxonomy, and Chair of the International Association of Botanical and Mycological Societies.
^*****Nicholas J. Turland is a botanist at the Botanischer Garten und Botanisches Museum Berlin, where he has worked since 2013 as head of publishing and editor of that institution's journals Willdenowia and Englera. He is also deeply involved in the International Code of Nomenclature for algae, fungi, and plants, serving as Rapporteur-général for the Nomenclature Section of the International Botanical Congress (Shenzhen, 2017, Madrid, 2024, and Cape Town, 2029). He previously worked for 16 years at the Missouri Botanical Garden (St. Louis, USA) on the Flora of China project and before that for three years at the Natural History Museum (London, UK) on the Linnaean Plant Name Typification Project.
