Mieridduryn (MI-eri-thi-RYN) is a genus of dinocaridid (a group of extinct arthropods) that lived during the Middle Ordovician of what is now the United Kingdom. This animal was described in 2022 based on a singular fossil found in Castle Bank, a Burgess shale type lagerstätte located in the country of Wales. Mierridduryn's affinities (relation to other arthropods) are somewhat uncertain, with two opinions currently being favored.
