When you are enjoying the American science fiction films, especially the films about the Apocalypse of the people or the enormous and fearsome animals, do you think about the real giant ones which were extinct in the past? Here are some kinds of huge extinct animals which used to live in North America.
- Enormous horned face, another name, Thunder beast
They were one of the most fearsome mammals about 30 million years ago and often wandered in the meadows in North America. They were the megacecrops (meaning “enormous horned face”) and had some other names like brontotherium (thunder beast), brontops, and titanops. They had the similar appearance to the rhinoceroses, and they were about 4.8 m long and mainly ate grass.
- Dire wolf
The dire wolf (Canis dirus) was about 1.5 m long and 100 kg weight and lived throughout America. According to the Dire Wolf Project, this wolf might be the competitor of the very well-known Smilodon because they both lived in the same period and their vestiges were found out together at the La Brea Tar Pits in Los Angeles. The first vestige was discovered in Evansville, Ind., in 1854. The dire wolf was not really an enormous animal when compared to the others in the same period; however, they are more vigorous than the modern wolf. It was supposed to be probably extinct about 10 thousand years ago.
Obviously, most people know about the Mammoth (Mammuthus primigenius). They had the same dimension with the recent elephants, but they had a hump like a camel’s one in their shoulders and a thick shag and a couple of giant curved tusk. Although they were very huge, they might not really scary, maybe since they were a plant-eating animal in the American and European grasslands. It was said that they were extinct because of being overhunted by the people about 10 thousand years ago.
A huge beast in America was basilosaurus, or “King lizard” in Greek. It was not a right name because basilosaurus did not have any the same features with the lizard. Actually, it was a giant whale which was up to 18 m long. This mammal could swim around America to catch fish and cuttlefish. They used to live about 35-40 million years ago in the Eocene period.
Plioplatecarpus, known as mosasaur, used to live in the North Dakota area when it was still covered by water until about 65 million years ago. This was extinct at the same time with the dinosaur. They were not dinosaurs but were enormous seafaring lizards which had the similar appearance to the illustration of the legend beast at the Loch Ness Lake. They had a long mouth and a rugged set of teeth and were about 12 m long.
- A croc-like animal, a tall bird, and an American sloth
The other noticeable animals are Hesperornis, a huge American bird which was about 1.5 m high with a rugged set of teeth lived in Cretaceous period (about 165-45 million years ago); Champsosaurus gigas, a croc-like animal, was extinct about 60 million years ago and lived in the waters of Dakota; and the final one, Megalonyx jeffersonii, a giant ground sloth, was extinct about 9, 600 years ago.
With the list above, we hope that readers can know as well as understand more about the animal’s world along with the history of the development of the wildness in North America.
