In the 1940s, the Brazilian precursor to the study of fossil vertebrates Llewellyn Ivor Price, unburied Prionosuchus plummeri from rocks of the Paleozoic Era with 270 million years of age. Known as Fire Stone Formation, these rocks outcrop in the state of Maranhao, and represent sediments deposited in ancient rivers and lakes surrounded by majestic vegetation. The Prionosuchus is the largest amphibious already found in the world, because it reached to nine meters in length. It had a long nozzle filled with sharp teeth, and an elongated body with too short members. Its role was the same as the current crocodiles: devour fish and any other aquatic creature.
Name: Prionosuchus plummeri.
Meaning of the Name: Although it may be an amphibian, his name means "sierra crocodile".
Where it was found: state of Maranhao.
When it lived: Permian Period, 270 million years ago.
Dimensions: Length: 9m, Weight: 1-2t.
One hundred million years ago, during the Mesozoic Era, lands that are now Brazilian were already almost fully occupied by different species of dinosaurs. They were concentrated in areas near the coast where moisture and vegetation provided food and shelter. In 2010 a group of paleontologists announced the discovery in rocks of Maranhao state coast of fossilized remnants that belonged to the largest predator dinosaur known to Brazilian lands: Oxalaia quilomboensis, which reached up to 13 meters in length. Different from what is commonly expected of a carnivore dinosaur, Oxalaia did not run behind its prey, it was a patient and experienced fisher. With its long beak and slightly bent teeth, it would blow the water quickly and accurately to take other incredible pre-historic creatures to eat.
Name: Oxalaia quilomboensis.
Meaning of the name: In tribute to Oxalá, a god of African legends.
Where it was found: Cajual Island, state of Maranhao.
When it lived: Cretaceous Period, 98 million years ago.
Dimensions: Length: 14m, High: 3m, Weight: 7t.
Seventy-five million years ago, already near the end of the Mesozoic Era, while large predators such as the famous Tyrannosaurus rex frightened herds of herbivores dinosaurs in North America, a group of very different predator dinosaurs frightened the rare South American forests. During the Cretaceous Period, these abelisauridae dinosaurs lived exclusively in continents south of the Equator. They were robust animal, short-skulled, very powerful rear legs, and arms exaggeratedly shriveled. Its fossilized remnants are found all over Brazil. At that time, huge herbivore dinosaurs from the titanosaurs family grazed in these lands and were among its favorite prey. In a generalized way, the Brazilian lands crisscrossed a long and endless period of aridity. In that pre-historic world, seek food for puppies and partners, and to its immense eight meters carnivore body, was not the easiest of tasks. The titanosaurs had their defense strategies: harshest bony plates on the back and enormous tails that would knock down any large predator. Also in pre-history, the struggle for life was always a challenge.
Name: Pycnonemosaurus nevesi.
Meaning of the name: Dense forest lizard.
Where it was found: state of Mato Grosso.
When it lived: Cretaceous Period, 70 million years ago.
Dimensions: Length: 8m, High: 3m, Weight: 4t.
Around 66 million years ago, the fall of an asteroid caused the disappearance of the majority of the lineages of dinosaurs, when South America already had its lands isolated as a large continental island. At that time, with the dinosaurs out of the loop, the mammals left their dens to give rise to incredible animals that, because of isolation, evolved only in those lands. Among these were the Xenarthra, of an unknown name, but very familiar to all Brazilians: the armadillos, sloths and anteaters. If nowadays these animals do not frighten us with their size, it was not so in the past. The armadillos grew up to the size of a Volkswagen Beatle and the sloths could reach the height of a bus. Eremotherium was a giant sloth who dwelt our land from 5 million to 10 thousand years ago, in a period called Pleistocene. With end of the last ice age 12,200 years ago, radical changes in climate and vegetation occurred here. Shaken with these changes and with the recent arrival of man, many of these giants did not resister and were extinct.
Name: Eremotherium laurillardi.
Meaning of the name: Solitary creature.
Where it was found: All over Brazil.
When it lived: Pliocene and Pleistocene Periods, between 5 million and 10 thousand years ago.
Dimensions: Length: 6m, Weight: 3t.
