The best known of the armored dinosaurs, the Ankylosaurus was the last and greatest of the Ankylosauridae, estimating its size at almost 10 meters long, more than 3 meters high and more than 4,000 kilos in weight.

He was quadruped and with a broad and robust body. Its tough skin was covered with bony plates and it could swing its imposing tail, striking its adversaries and causing, for example, a predator to limp.

Its skull was very broad and low, with two horns pointing back from the back of the head, and two other horns below these.

The Ankylosaurus belongs to the Ankylosauridae family, and among his close relatives we can find Anodontosaurus and to Euoplocephalus.

This dinosaur is known to fossils found in Montana and Alberta.

Ankylosaurus feeding

The Ankylosaurus was herbivorous like other ornithischia. In their diet it is believed that there were tough leaves and fleshy fruits, and perhaps fibrous and woody plants, although the latter is under review.

Furthermore, it probably fed on ferns and low-growing shrubs, reaching 60 kilos a day.

Ankylosaurus defenses

The Ankylosaurus was a very well protected dinosaur by strong bony plates, although it is believed that the musculature under them was rather weak.

These plates would be embedded directly in the bone tissue, a unique characteristic in the ankylosaurs, which gave them a light and durable armor, protecting them impeccably against their predators.

The paleontologist Kenneth carpenter suggested in 1982 that armor also played a key role in the thermoregulation, just as it happens with current crocodiles.

Ankylosaurus habitat

The Ankylosaurus lived between 68 and 66 million years ago, in the Maastrichtian, Cretaceous period, being one of the last genera of dinosaurs that appeared before the Cretaceous-Paleogene extinction event.

After studying History at the University and after many previous tests, Red Historia was born, a project that emerged as a means of dissemination where you can find the most important news of archeology, history and humanities, as well as articles of interest, curiosities and much more. In short, a meeting point for everyone where they can share information and continue learning.
