One of the newest giant carnivorous dinosaurs is Brazilian. With seven feet long by three tall, the big predatory was unearthed in the region where today is the Chapada dos Guimarães, Mato Grosso. He lived there for 80 million years ago during the Cretaceous period and joined the list of the largest and most feared beasts of all time. This is the Pycnonemosaurus nevesi, dubbed the "Great Hunter", found in Chapada dos Guimarães (MT) for over 50 years and forgotten in Rio de Janeiro until 2000. It was a dinosaur of the group of abelissauros, large predators also found in Argentina and Africa, and lived more than 80 million years ago. The "Great Hunter" should have between 7 and 8 feet long, 3 feet tall and weigh over 2 tons.

The beast has been nicknamed Rondon II, a tribute to Rondon. Rondon I (the first nicknamed Rondon) refers to an herbivorous dino found in Minas Gerais. Beside the scary creatures as Tyrannosaurus rex and Giganotosaurus argentine galalau Carolini, Rondon II was one of the giants who ruled the top of the food chain from pre-history. The Abelissauro had a large skull and light that could exceed 80 cm in length, allowing the head to move with ease, this combined with the muscular legs, which turned into a fearsome predator.

The Abelissauro or "Lizard Abel"was a dinosaur that lived in Brazil, Uruguay and Argentina, during the Cretaceous period. Media 3 feet tall and 7 feet long and weighed between 1.5 and 2.5 tonnes. It was a bipedal carnivore, first found in 1985 in Argentina. It presents superficial similarities with the Tyrannosaurus. The name "Lizard Abel" is because of the fossils have been discovered by a man named Robert Abel, who found fragments of dinosaur in Patagonia, more precisely, in the training Allen. The Abelissauro's skull was never found whole, only found a piece of the skull out of 85 cm2 incomplete, together with long teeth and thick. Along with the Carnotaurus, the Abelisauro comprises a family of previously unknown dinosaurs, the Abelisauridae.

The possibility of large carnivores in Brazil was a mystery that puzzled paleontologists. Until the discovery in Mato Grosso, the majority of findings regarding carnivores in the country was fossilized teeth.

The Brazilian dinosaur has characteristics typical of other giant carnivores. The teeth with wrinkled enamel, which facilitate the opening of the leather of the prey, are those of Giganotosaurus. The shape of the vertebrae is similar to Carnotaurus, another large predator. "All animals are quite large and close in the evolutionary chain, " says Kellner.

Rondon II probably was not the only large predator that lived in Brazil in pre-history. In Maranhao have been discovered dozens of teeth Carcharodontosaurus saharicus - another giant that had more than ten feet long by four tall, also found in Africa.

But the most complete remains of dinosaurs in Brazil are in the Araripe, a board of 160 km, located in the south of Ceará, Pernambuco and Piaui. There were the remains of Santaraptor placidus, a dinosaur softly (1.50 meter), who lived in herds and fed on small animals and remains of meals of larger animals. The examination of fossils 110 million years showed signs of leather, petrified muscles, and blood vessels and skin. "No dinosaur fossil in the world in the same state of preservation, " said Kellner, chief of staff who reported the findings.

Excavations carried out at the Araripe (EC) reports 350 copies of 19 different species of pterosaurs, winged species of reptiles that lived at the same time of the dinosaurs and could have up to 6 meters from the tip of one wing to another. Many of these animals were given names tupiniquins (brazilians) like Tupuxuara the Anhangüera or Tapejara. Among the most famous is the Thalassodromeus sethi, a pterosaur with a huge bony crest and beak-shaped scissors. It is believed that he was fishing with his beak into the water. "Pterosaurs are found in various places in the world, but as they were flying and had fragile skeleton, rarely have such good condition, "said Kellner, author of the discovery, which merited the cover of Science magazine, one of the most respected scientific journals in world. In October 2005, Kellner and Chinese scientists announced the discovery of two new species of pterosaur (photo) in Liaoning, China. Replicas of the Chinese species are exhibited in the National Museum in Rio de Janeiro.
