This particular horse species is Equus giganteus, an extinct horse believed to be a prehistoric species that lived during the Pleistocene era, and was first discovered in Idaho in 1932. The fossilized remains of this species were examined by paleontologists, and they were able to determine that it was indeed a distinct species of the horse. Below, we discuss the massive size of the horse bigger than a grizzly and how it compares to other species today.
The Equus Giganteus
The Equus giganteus existed from the Blancan Period (which overlaps with the early Pliocene Epoch of the geologic time scale) to about 12,000 years ago, near the end of the Pleistocene Epoch. The literal meaning of this horse’s name is “giant horse.” It befits the animal, as it was essentially a gigantic modern horse. According to the researchers who discovered this species, it had an estimated weight of around 2,600 and 3,300 pounds. This means that it could weigh more than two adult grizzly bears together! It would be interesting to see how the Equus giganteus towers over other giant mammals today. Below is a list of mammals being compared to Equus Giganteus.
Equus Giganteus and Grizzly Bear Size Comparison
If the Equus giganteus still exists today, it would be easy to compare it to a grizzly bear in size. The Equus is unquestionably bigger than the grizzly, weighing more than twice the latter’s size! The grizzly bear is a brown bear subspecies found in North America. Grizzlies are brown, although their fur can appear white-tipped or grizzled, giving them their name. Grizzly bears are legally protected in the mainland United States, but not in Alaska, despite recent controversial attempts to repeal such laws. The Equus giganteus is a species of horse that also lived in North America. It was a very large species of horse, with males reaching up to 6.6 feet high at the shoulder and weighing from 2,600 to 3,300 pounds. The females were generally smaller than their male counterparts, reaching a maximum height of 5.2 feet at the shoulder and weighing up to 1,200 lbs. On the other hand, grizzly bears are also large animals, with males reaching up to eight feet long and weighing up to 600 lbs (270 kg). Females are generally smaller than their male counterparts but can still reach six feet long and weigh as much as 300 lbs (135 kg).
Modern Horses vs. Equus Giganteus
Modern horses are the perfect animals for many reasons. They can be used for riding, racing, or simply as a workhorse on a farm. However, modern horses are quite small compared to Equus giganteus in terms of size and weight. For instance, the average height of a modern horse is around four feet, and it weighs between 900 to 2,000 pounds, depending on the breed. The difference between these two horses can be attributed to their evolutionary history. While Equus giganteus was able to grow so big due to evolution and natural selection over thousands of years, modern horses have been domesticated by humans. Experts bred them for specific purposes, such as riding or pulling carts; therefore, they are smaller than their wild ancestors.
Bison vs. Equus Giganteus
We all know that bison are huge mammals native to North America and are found in many places, including Alaska and Canada. They eat grass and other plants that are found around lakes or rivers, which helps keep those areas healthy by preventing soil erosion during floods or droughts caused by climate change. Now, how big is a bison? Bison are large animals that can weigh as much as 2,000 pounds. They have long, thick hair and horns that are about two feet long. On the contrary, Equus giganteus was a horse that typically weighed around 2,600 pounds. The difference in size between these two animals is quite remarkable, but both animals have their own benefits. Apparently, Equus Giganteus is bigger than a bison.
Rhinoceros vs. Equus Giganteus
The rhinoceros is a large herbivorous mammal native to Africa and Asia. Rhinos are some of the largest animals on Earth, and they are also among the world’s most endangered. The two species of rhinoceros that exist today are the white rhinoceros and the black rhinoceros. The white rhinoceros is native to southern Africa, where it can be found in grasslands and open woodlands. It can weigh from 4,000 to 5,500 pounds and grow up to 11.5 feet long. The black rhinoceros is native to eastern and central Africa; it weighs around 1,760 to 3,090 pounds on average and grows up to 9 to 12 feet long. Considering the size the rhinoceros can grow to, it is deemed bigger than the Equus giganteus. The rhinoceros is the second largest land mammal behind the elephant and can weigh up to 6,000 pounds. The Equus giganteus, on the other hand, was theorized to have been able to grow up to 9 feet tall and weigh up to 3,300 pounds.
