Chasmaporthetes



This prehistoric animal is an animal very curious. Due to the different characteristics was an animal uncommon, and is called Chasmaporthetes, although not really a distinct species, it really is the family of a peculiar group of hyenas. Chasmaporthetes size is about 1 meter (3,3 ft) tall at the withers and an average of 80 kg (170 lbs). To get an idea, would be as large as the spotted hyenas that appear in documentaries in Africa but, more graceful, slightly taller and less robust.

The two main features of this hyena are:


First, their teeth. The Hyaenidae are characterized by a modified dentition for intervention on the hard tissues of the mammalian skeleton, and this is because most species are scavengers. However, representatives of the genre were primarily hunters Chasmaporthetes. I remember talking about the kind of prehistoric hyena Pachycrocuta (giant hyena), had a bite so powerful, so strong teeth and was so great that I could grind up the bones of elephants, LINK.

But back to what we want. When the experts found the jaw of Chasmaporthetes began to think that this species were mostly carrion, but rather active predators. To understand the difference, we could say that their molar teeth were made to cut, and not crushed. Something like the current cats, they are better equipped to hunt than to live on carrion.

The idea that predators were reinforced when analyzing its skeleton, found that their physiology was specialized in speed. Experts think that the Chasmaporthetes could reach up to 100 km / h (64 mll/h) and had to compete with the giant cheetah Acinonyx pardinensis of the time. Her long legs and slender body adapted to the speed, gave him a look that is classified in the group of hyena-like dogs ... talk about it another day.


Secondly, its distribution. We are accustomed to seeing the hyenas in Africa or South Asia and is easy to think that we in the east half and the Strait of Gibraltar, the hyenas could colonize Asia and Europe. For example, in Europe was the spice Chasmaporthetes lunensis. Well, another species, called Chasmaporthetes australis was the only species of hyena that through the Bering Strait colonized all of North America. This may not tell you much but it was this species, the swift hunter hyena, hyena more common around the world and of all time (although it is hardly known today). Lived parts of the world more than any other hyena, whether extinct or still alive.

Chasmaporthetes is a genus that lived in Europe, Asia, Africa and North America about 15 million years ago during the Miocene. In short, a sort of prehistoric animal that I thought you would like to know if you love animals, prehistoric or not.

Cheetah Giant or Acinonyx pardinensis

The problem that presents itself now is the cheetah who specializes in speed, his muscles has focused on this goal. That's why the dams are often stolen by other predators such as lions, hyenas, leopards even African dogs. Well, there was an ancestor who lived in the Quaternary, the Pleistocene (over 1 million years) and with a size twice as large as the current cheetah, reaching weigh over 120 kg (264 lbs)and over 2 meters long excluding the tail(6 feet 3 inches). High BMI, used more nails (in comparison with modern cheetahs), suggesting that it was less suited to high speed, although it is believed that he could reach over 70 mph(lower than the current but faster than everyone else cats. We must remember that current Cheetahs reach speeds of 115 km / h.
But this theory suggested by the great weight is offset by the antithesis: you think you might be even more than the current cheetah because its legs were of a larger size.
Because of its bulk, it needs to go very fast after prey. Deer, mountain goats, moose and sambar (deer species) were their prey.
It is thought that went extinct 10,000 years ago.
