Likely bred on Isla Sorna during the mid to late 80’s, 16 Euoplocephalus were cloned for Jurassic Park, under the revision number of version 4.0.[1][2] not much, is known about these dinosaurs, considering the fact that they made no physical appearance, nor were described at any point, during the duration of the novel. However, by the end of the InGen Incident only 9 survived,[3] likely being killed by the escaped Tyrannosaurs and Velociraptors. Ultimately the surviving Euoplocephalus were all killed by the Costa Rica Napalm Bombing that followed after the incident.[4] It is unknown if there were ever any populations that survived on Isla Sorna.
