It was described in 2005 based on a fossil discovered in the Escuminac Formation of Quebec, Canada two years prior. It was approximately {{convert|44|mm|in|abbr=on}} long and 10 mm wide with 27 body segments, and had kidney shaped patches of ocelli (simple eyes). Each trunk segment had long, sickle-shaped extensions (paranota) projecting laterally, and was decorated on the dorsal surface with low rectangular bosses ("bumps") bordered by crescent-shaped bosses. The genus name Zanclodesmus derives from Greek Zanklon, meaning "sickle", in reference to the long, curved paranota, and desmus, a common root word in millipedes. The species name willietti honors Miguasha National Park warden Jason Willett, who discovered the fossil.[1][2] References1. ^{{cite journal|last=Wilson|first=Heather M.|author2=Daeschler, Edward B.|author3= Desbiens, Sylvain|title=New Flat-Backed Archipolypodan Millipedes from the Upper Devonian of North America|journal=Journal of Paleontology|year=2005|volume=79|issue=4|pages=738–744|doi=10.1666/0022-3360(2005)079[0738:NFAMFT]2.0.CO;2}} 2. ^{{cite web|title=Zanclodesmus|url=http://www.miguasha.ca/mig-en/zanclodesmus.php|website=Miguasha National Park|accessdate=25 July 2014|year=2007}} External links
