恐竜説明：

Ankylosaurus was a truly massive dinosaur.

It was the largest ankylosaur, with some scientists suggesting that there may have been giants of 15‑17 m long.

These would have weighed over ten tonnes, and it is extremely unlikely that even Tyrannosaurus rex would have tried to kill a healthy animal.

Adults had skulls over 1 m in length. The skull was broad with a very thick roof and four triangular horns on the back corners.

The snout was beak‑like and the animal fed by snipping or cutting plant material, which was then finely ground by the small teeth that covered the palate. Bony shields which fitted into one another covered the neck and body of this slow‑moving titan, and there was a huge club at the tip of the tail.

The club was made up of two heavily thickened bones, one on either side of the tail. Though they were very heavy, the tail and the club were held high off the ground. If attacked, Ankylosaurus would try to move into a position where it could land heavy blow on the legs or soft underbelly of the attacker.
