Panthera tigris acutidens


I'll tell you a secret. When we speak of prehistoric big cats, the most powerful, the most dangerous and terrible hunter, it's easy to come to mind two species: the Cave Lion (Panthera leo atrox) and the saber-toothed tiger (Similodon).

But really, there is another species that is probably the most terrible, strongest, largest cat that ever lived and that's a real unknown to the general public, it is the Panthera tigris acutidens. A cat can only hunt animals such as Stegodon (which is a type a type of small elephant) or Calicoterio. To get an idea, this prehistoric cat could hunt down an actual cape buffalo. One of those we see in documentaries Africa needed 4 or 5 lions to tear it down.

Panthera tigris acutidens, as the name suggests "tigris" is a kind of tiger. In fact it is considered a direct ancestor of the Asian tiger, the largest today.

Little is known of this beast. It was not only larger than the largest tiger today, it was also more massive. Therefore, it is thought that it was not a long distance runner, but short and quick, races depended stalking and grounds overgrown jungle that allowed close enough to approach their prey in a quick race. It is believed that could weigh 450 kg (992 lb), 100 kg (220 lb) more than the Siberian tiger. Moreover, the cross came to 1.30 meters and tail, could reach almost 4 meters (13 ft,).



The tusks of this were in line, about 15 cm in length. And when I was able to reach its prey nailed them like sharp daggers or spine smashed or crushed trachea hunted animal.

He lived 2 million years ago and it is not known exactly when it died ... in the early Pleistocene. In cold, snowy woods of what is now China and other parts of Asia, where its winter whitish camufrarse allowed.

Chirostenote


Ladies and gentlemen, sorry for a season without dealing the blog as much as I would have liked, but that is over. Moreover, nothing happens, the dinosaurs are timeless and, in gratitude and with intent to redeem myself, I want to show you one of the most picturesque dinosaurs that ever lived. This is the Chirostenotes, the "narrow hands."

You see the image below, you will understand what the name refers Chirostenotes or "close hand" ... no trick, its hands were narrow.



The "hands" of this saurian, were long and narrow, with very long fingers ending in sharp claws. That is the main feature.

Another feature of this prehistoric animal was its head. Look at the image below.


You know who is? As this animal is a Cassowary, a bird now living in Australia and New Guinea ... and is very aggressive. It is thought that the ridge has the Cassowary is similar to that which took the Chirostenotes. In fact, it seemed a little ... even thought this lizard was a bird. It had feathers, was bipedal, lakes and light arms and a crest like a Cassowary. But it really was not a bird.

Chirostenotes's jaw was sort of a parrot but was full of teeth. Media about 3 meters long and when were stood as tall as the average man. Grew to weigh no more than 60 kg. And think were fast and agile hunters who traveled at high speed and making great leaps and light careers.

It lived 75 million years ago in what is now Canada. And it is known today more than ever, especially for children, as it is one of the protagonists of the series of drawings Dinotren. Is smug and was known as Keenan.
