Troodon


Now Troodon has thousands of fans who are children of 2-7 years old ... or a little more. Although it was one of the first dinosaurs found, now it gets to know as one of the characters in a cartoon series, a character friendly and fun. But that image is far removed from reality. In fact, "Troodon" name literally means "wounding tooth", so get an idea.


The Troodon belongs to the group of theropods (prehistoric animals with strong back legs). A suborder where we find most frightening terrestrial species of the story ... as the Spinosaurus, Tyrannosaurus rex or Allosaurus. Referring to the teeth, the Troödon were quite different than that of other carnivores mentioned.
The teeth of T. Rex were as heavy knives, however, were those of Troodon elongated narrow and sharp edges saws ideal for tearing flesh.


Indeed, this animal lived in the upper Cretácido became extinct 70 million years *. It was a prehistoric carnivore forests in what is now North America. But it never became an apex predator as their size was relatively small and could not compete with other theropods.


It reminds me a little velociraptor. First because of its size and secondly because they were very similar morphologically. The two, Velociraptor and Troodon, were very close (evolutionarily speaking) birds and probably both had feathers. Although they could not fly ... we leave that to the birds. But maybe it big jumps or even plan a few meters.

The Troodon was twice as large as the velociraptor. Was elongated like this, also agile predator and 1 meter in height and two in length, weighing up to 50 kg. A Trodonte of these, a human could make enough damage or even kill it.

But do not demonize an animal and say it's bad. But if you're a parent and your child likes Troodon, you know it's not the friendly character we see in the series of "Dinosaur Train". He was an active hunter, a predator elongated as a young Komodo dragon but occasionally will put on its back legs.


* If you look at this picture, you will see that next to the Troodon's one of the "Aliens" that were found in Roswell. According to a paleontologist: these alien beings would be the trodontes that survived the mass extinction of dinosaurs and evolved ... Over millions of years evolved and could reach out to Earth, then returned and are in Roswell .... curious ...

Epicyon.



Actually, the largest and heaviest wolves may be found in cold northern areas of America and Asia, including Canada and Alaska and the Russian steppes. Normally, these wolves do not exceed 80 kg (176 lb), when they do it is because we are talking about huge wolves, strong, sturdy and large and possibly have been bred in captivity. However, the size of these big wolves is nothing to what I could weigh the Epicyon. A prehistoric wolf stood at 170 (360 lb)kg.

Their name, Epicyon, means literally "more than a dog". And it really is bigger than a dog, from snout to tail could exceed 2.5 meters (9 ft.)(which dog measure that?). In addition, the Epicyon was part of the subfamily of Borophaginae, a group of ancient canids whose name means "bone crushing dogs", in reference to its strong and resistant teeth can crush the bones of its prey. Something like the teeth of hyenas ... when they had not yet appeared on earth. To get an idea, it has been observed that a wolf has a bite pressure of 270 kg  (590 lb) as much as Epicyon morphology, this was over 600 kg (1322 lb)... we just got to the 80 (176 lb) kg of pressure.


It is thought that these prehistoric animals lived and hunted in packs ... thus achieving a great success in their survival. Stalked and hunted with its teeth large and small prey such as (antique mammoths, deer and the Synthetoceras or calicotéridos). The success of their survival was such that the Epicyon lived thousands of years, millions of years. Exactly 15 million years is one of the top predators. Virtually the entire Miocene Epicyon lived as it appeared 25 million years ago and disappeared for 5 ..... an eternity compared to the survival of the species homo sapiens.
