ZEM was a former admin and bureaucrat on Primeval Wiki. He joined in December 2008 and left the wiki in January 2013. Before the overhaul he made over 21,000 edits and kept the wiki clean and vandalism free. He even got in contact with the cast and the people behind Primeval and Primeval: New World. When he retired, he left the wiki up to TroopDude and The Palaeontologist.
