Marley is a male Spinosaurus aegyptiacus "robustus" played by Coop.
Cloned in 1986, Marley is one of the original Spinosaurs on Isla Sorna. As a chick, he was terrified of the cars InGen employees drove around the island, nearly being hit by them on several occasions. During Hurricane Clarissa, a tree crashed onto the fence of Marley's holding pen, freeing him from captivity. Marley ran off into the jungle and began his life of freedom on Isla Sorna.
Marley is a relatively stoic Spinosaurus. While he usually tolerates other predators, Marley has little patience for Tyrannosaurs and Giganotosaurs, even killing Prince when he and Princess attempted to destroy the nest.
