Euoplocephalus was an ankylosaurid Dinosaur from the Mid-Late Cretaceous of North America. This dinosaur weighed 2 tons and had a width of 2m and was around 6m long. Euoplocephalus was equipped with fused bone plates on its back that acted as body armor as well as a pair of horns that protruded from the back of the neck, possibly as a defense against being grabbed by the neck. For defense Euoplocephalus was armed with a foot wide tail club that could be swung like a medieval flail and had the ability to break bone. In addition Euoplocephalus also supported a pair of armored eyelids, like Ankylosaurus.

According to the Dinosaur Protection Group, Euplocephalus went extinct on Isla Nublar in 2018.[1]


Euoplocephalus was sucessfully created by InGen on Isla Sorna for Jurassic Park on Isla Nublar. It is assumed they lived in the Triceratops Territory with Triceratops and possibily Styracosaurus.

By August 16, 1989, there were 16 Euoplocephalus living in the park and they were Version 4.0.[2][3]

By the end of the InGen Incident there were only 9 that survived,[4] the ones that did not most 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.[5]

It is unknown if there were ever any populations that survived on Isla Sorna.

The Euoplocephalus has three attacks, a charging attack, a lunging gore, and a tail swipe. In addition to jumping onto the Euoplocephalus, it will cause you damage due to the horns on the back. To defeat the Euoplocephalus you need to pounce on its head and then lift the animal onto its side where you can then attack the dinosaur's belly.
