Gigantoraptor.

The Gigantoraptor is half bird, half dinosaur, not known, but what is .... is that it is a mystery.

Discovered in 2005 in the Gobi desert, lived 80 million years ago in the land of the Cretaceous period.
Its resemblance to the birds include anatomical features such as a peak instead of teeth in the jaws and the possibility of being covered with feathers. That's why we think it is the largest winged animal that has never existed. Whether flying or not.

Another question that appears on this prehistoric animal, half dinosaur, half bird, is your diet: it is thought that it was herbivorous, but on the other hand, has strong claws and is regarded as agile and fast moving, predatory characteristics. In short, we'll know later.



But how long the Gigantoraptor? For their measurements are 5 meters (17ft) tall to 8 meters (26ft) long and weighing about 2 tonnes. Oviraptoridae family, is the oldest. The Oviraptoridae are a group of dinosaurs known to include many feathered species. Gigantoraptor was much larger, about 35 times larger than its likely close relative, Caudipteryx.


Kelenken guillermoi.

Some time ago we spoke of wallerian Titanis, the second largest bird of the subfamily Phorusrhacidae, or better known as terror birds. It should be noted that in the Subfamily Brontornithinae Terror Birds are heavier and bigger as the bird Brontornis.


Phorusrhacidae and Brontornithinae are subfamilies of the family of Phorusrhacids.Anyway, on with the Kelenken.

The largest bird is the Kelenken guillermoi. He lived in South America 15 million years ago (Miocene), recall that lived in North America wallerian Titanis for 5. And he could measure up to 2.5 meters tall and weigh about 160 kg elenken was quick and could hunt and devour rodents, reptiles and small mammals.

It is the largest known predatory bird in history. And not just any predator was in the top of the food chain, and could face other super-predator of the time.


Two features of Kelenken guillermoi my attention:

1 - The size of the head: This came to be more than 70 cm long, with the bird known as the largest skull. Imagine a large ostrich, but with a pointed beak and hook and 7 times larger. All supported by a robust and strong neck.

2 - The second thing that strikes me is the speed: I could outrun an ostrich. The ostrich is known for the speed provided by its two strong legs, reaching up to 65 km / h. The Kelenken guillermoi being young could reach 100 km / h. Come on, that may strike a galloping horse without difficulty.
