Zhang fleeing from humans along with many other dinosaurs.
Zhang is a Mamenchisaurus rp'ed by T-rex-king. One of the oldest dinosaurs, he was seen when InGen returned to the island to attempt to capture some dinosaurus for their park in San Diego as he attempted to flee from the humans. Fortunately for him, he avoided capture (mainly because InGen didn't bother due to his size) and has been left alone to roam the island. Recently, he has been tagged along by an Iguanodon named Girovago.
