Not much is known about Nicolas de Huelva. He was a fourteenth century Spanish cartographer, (this information was found on another Jurassic Park FANDOM wiki, ‘JURASSIC-PEDIA’). He called Isla Nublar Cloud Island.
Nicolas de Huelva has only ever been mentioned in marketing for Jurassic World. (This info was also taken from JURASSIC-PEDIA.)
