Another [[species]] is found in the Lower Cambrian [[Maotianshan shale]] of [[China]]. ''Hallucigenia'' was thought by [[Stephen Jay Gould]] to be unrelated to any living species, but most palaeontologists now believe that the species was a [[velvet worm]], a relative of modern arthropods.<ref>{{cite news|url=http://discovermagazine.com/1992/may/whoseviewoflife52|title=Whose View of Life?|last=Lewin|first=Roger|date=1 May 1992|work=Discovery Magazine|accessdate=2009-10-23}}</ref> Unlike its contemporary ''[[Aysheaia]]'', ''Hallucigenia'' has very little resemblance to mode
