Jurassic Park Series 2

Ankylosaurus was like a tank, with lots of thick, bony armor on its body. It also had a nasty weapon, a heavy club on the end of its tail, which it could swing around and smash into an attacking dinosaur. There probably weren't many creatures, even a big Tyrannosaurus rex, who would want to mess with this formidable species.[1]

As a defensive creature, Ankylosaurus was one of nature's most perfect designs. It was almost impervious to being bitten from above and its long, strong tail muscles would have been able to swing its club with great force, however, the tail wasn't too flexible and could only swing 45 degrees in each direction.[1]

There is very little fossil material from this dinosaur - it was apparently the last and largest of this family of armored dinosaurs. It walked fairly upright on all four legs, carrying its tail off the ground and it is theorized that it would drop to the ground when attacked to use its armor as a shield to cover its legs and underbelly.[1]

Wikipedia has a more detailed and comprehensive article on Ankylosaurus



Ankylosaurus was successfully recreated by InGen in the lab on Isla Sorna. The ankylosaurs were parented and fed in captivity on the island. Ankylosaurus a dark tan underbelly with bright red patches on the eyes and its armor was black.

For unknown reasons, it was not planned to appear in Jurassic Park.[2]

Living in the wild

When Hurricane Clarissa struck Isla Sorna, the InGen personnel left the island. The stegosaurs were either set free by the workers, broke out on their own or because the storm had damaged fences. Ankylosarus roamed freely across the island.

The Ankylosaurs had to learn to live in the wild. Since they no longer received lysine supplements in their food, they started to eat lysine rich plants. It is unknown how many Ankylosaurs lived on the island, but they were known to have resided in the jungles of the northeast.

In Jurassic Park III, Ankylosarus were briefly encountered near a river where Dr. Alan Grant and the Kirby family road a boat through.

Jurassic World

Masrani Global Corporation created a new dinosaur zoo on Isla Nublar: Jurassic World. These new clones had grayish skin and dark gray armor with white spikes.

"That evidence of thanatocoenses I thought I saw from the helicopter was in fact the remains of the ankylosaur herd. A predator must have driven them off the cliff, so I’m afraid they are, once again, extinct."

If this scene was to have been shot it would have put future appearances of Ankylosaurus in jeopardy.

  • Two scenes of Ankylosaurus was removed from Jurassic Park III. This is included a battle between an individual and a pack of Velociraptors and a more peaceful scene of a herd of three crossing the river that Dr. Alan Grant and the Kirby family were on.

Jurassic Park: Operation Genesis

see Ankylosaurus/Operation Genesis

Ankylosaurus may be seen as a four-star large herbivore in the video game Jurassic Park: Operation Genesis. It prefers watery environments like lakes and rivers. It is possible for it to engage in "Death Duels" with Tyrannosaurus. Tyrannosaurus rex sometimes comes on top by snapping the Ankylosaurusneck (holding its head down with its foot and then twisting it with its jaws) or by being attacked from underneath. This is possibly meant to reflect the T. rex and Ankylosaurus battle in BBC's Walking with Dinosaurs. This dinosaur has the highest hit point value at 1600 this is higher than other large and armored dinosaurs like Brachiosaurus and Stegosaurus.

An Ankylosaurus figure appears in the Jurassic Park Series 2 toy line as a hatchling. It also makes an appearance in the Jurassic Park Junior line. Another Ankylosaurus figure was originally planned for the Jurassic Park 2011 toys packaged with a newly sculpted Spinosaurus, but in the end it was scrapped like the rest of the line.
