New Crocodile Fossil



Recently in Bogota, paleontologists found the fossilized crocodile admitted along 6.1 at a coal mine in Colombia. Giant freshwater crocodile named Acherontisuchus Guajiraensis seems to live in the rainforest environment, or in the same habitat as the world's longest snake known as Titanoboa an estimated length of 12.8 meters.
According to scientists the ancient rain forest ecosystem is dominated by a giant reptile reptiles, including snakes, turtles and crocodiles. Crocodile fossil found this is the second fossil found in Correjon mine in northern Colombia.
From this can be ascertained fossil crocodile alligator had once been competing for food with the world's longest snakes crocodiles because the main food is fish. Fossils of a newly discovered species of crocodile is a part of a group known as Dyrosaurids crocodile. This crocodile is believed to be inhabitants of the ocean, and is a coastal reptiles. But a new adult specimens to contradict the theory that mentions A. Guajiraensis only live in fresh water as a baby and will return to the sea as adults.
This discovery was not the first time since the year 2009, three new species of giant crocodiles were also found. The first is Kaprosuchus Saharicus species, or dubbed BoarCroc found in Niger. BoarCroc are meat eaters that have a length of about six feet with a hard armored snout used for butting an enemy or prey, and is equipped with three sets of fang-shaped dagger to cut and tear their victims.
The second is a species of crocodile Araripesuchus Rattoides, called RatCroc also found in Morocco. Crocodile with a length of about one meter this is a plant-eating crocodile that has a pair of jaws in the rear and below. Jaw function was used for chewing food.
While all three types of crocodile are Laganosuchus thaumastos or PancakeCroc, which came from Niger and Morocco. With a length of 20 feet or about six feet, this is a fish-eating crocodile. Also has a snout crocodile is one meter long and slender spike-shaped teeth in its jaws.
Three new species, two previously known as an ancient crocodile. Dr. Sereno, the inventor says that the species is to open windows to the world if it turns out crocodiles are animals that are alien to life on the northern continent. Animals that lived 100 million years ago in the southern continent known as Gondwana. The researchers say that the animal could gallop on land chasing prey. But also dive into the water and swim. African crocodiles seem to have legs that can be upright, the feet were able to jump around with agile on land and has a tail versatile for paddling in the water. Animals with the talent of this amphibian in the past may be key to understanding how they evolve and to survive the era of dinosaurs. Talent amphibious crocodile crocodile is in the past may be key to understanding how they could run and survive in the age of dinosaurs. Sereno added, though they could not run fast like a horse, but this type of crocodile can move pretty fast. In addition to finding three new species of crocodile, Sereno and Larsson also discovered two species of crocodile fossils ever found before the minor and Araripesuchus Anatosuchus wegeneri.
Both of these crocodiles are both found in Niger and has a length of about one meter. The difference, Anatosuchus minor species has a wide muzzle and nose like Pinocchio. These species prey on fish, frogs, and caterpillars as well as having a special sensor on the tip of snout to locate prey in shallow water. While the species has a nose like Araripesuchus wegeneri dog's nose and eat the plants happy.
