Ankylosaurus

In Real Life
Ankylosaurus was the largest-known ankylosaurine dinosaur and possibly the largest ankylosaurid. In 2004 Carpenter estimated that the individual with the largest-known skull (specimen CMN 8880), which is 64.5 centimeters (2.12 ft) long and 74.5 centimeters (2.44 ft) wide, was about 6.25 meters (20.5 ft) long and had a hip height of about 1.7 meters (5.6 ft). The smallest-known skull (specimen AMNH 5214) is 55.5 centimeters (1.82 ft) long and 64.5 centimeters (2.12 ft) wide, and Carpenter estimated that it measured about 5.4 meters (18 ft) long and about 1.4 meters (4.6 ft) tall at the hips. The American paleontologist Roger B. J. Benson and colleagues estimated the weight for AMNH 5214 at 4.78 metric tons (5.27 short tons) in 2014. In 2017, based on comparisons with more complete ankylosaurines, Arbour and Mallon estimated a length of 7.56 to 9.99 meters (24.8 to 32.8 ft) for CMN 8880, and 6.02 to 7.95 meters (19.8 to 26.1 ft) for AMNH 5214. Though the latter is the smallest specimen of Ankylosaurus, its skull is still larger than those of any other ankylosaurins. A few other ankylosaurs reached about 6 meters (20 ft) in length. Because the vertebrae of AMNH 5214 are not significantly larger than those of other ankylosaurines, Arbour and Mallon considered their upper range estimate of nearly 10 meters (33 ft) for large Ankylosaurus too long, and suggested a length of 8 meters (26 ft) instead. Arbour and Mallon estimated a weight of 4.78 metric tons (5.27 short tons) for AMNH 5214, and tentatively estimated the weight of CMN 8880 at 7.95 metric tons (8.76 short tons).

In Prehistory
Ankylosaurus is without a doubt the most durable dinosaur in the game, with 300 defense. It has a very unique play-style. While its health and mass isn't great, it certainly makes up for what it lacks with defense. It also has excellent damage, even topping Tyrannosaurus', and evenly matching Andesaurus' kick attack. The only real disadvantage Ankylosaurus has is its mobility. It has the worst turn radius in Prehistory, and although its attack is pretty long ranged, it doesn't really serve the mobility much justice. Despite all of this, Ankylosaurus pretty much obliterates any apex carnivore in a face-tank, even the T. rex. Ankylosaurus isn't too common due to being a slightly worse choice than the Triceratops, as the Trike is more of an all rounder than the Ankylo. But, as suggested before, Anky's game-play style is quite unique. Instead of purely rushing in, or perhaps doing the "hit and run" technique that Allosaurus does in combat, all you have to do is keep your opposition behind you, and use your rangy attack to your advantage. Ankylosaurus in many people's books is a very underrated Prehistory dinosaur.

Pros

 * Most durable dinosaur in game
 * Most base damage (tied with Ande) in Prehistory
 * Cheaper than Triceratops
 * Can kill every apex if played right
 * Can't be damaged by most Tier 4s due to great defense

Cons

 * Incredibly poor mobility
 * Slow
 * Mediocre hunger time
