Dino breathing

This type of iguana is not a dinosaur a genus that contains multiple species, al of which had four legs and ate plants. Most grew to be about 30 feet long. The first Iguanodon fossil was discovered by Mary Ann Mandel in 1820, before the word "dinosaur" was found in Sussex, England. The shape of the tooth is huge. She named it the Iguana, because she thought that many of the structure of the procession resembled the larger version of an Iguana tooth. The tooth resembles the appearance of the tooth, so she named the model Iguana. A complete skeleton was later discovered by paleontologists, which allows Mantel to know what kind of animal his tooth belongs to The dentist is now on display at the Te Papa Museum.  It is in New Zealand. One of the most distinctive traits of dinosaur in the iguanodon genus is a large, spiky thumb. This dinosaur's thumb looked like a horn and the first representatives put it in the nose, not the hand. Researchers have significantly altered th

Giganotosaurus One of the newest additions to the world of dinosaurs arrived with a media splash in 1995 when paleontologist Rodolfo Coria of the Carmel Funs Museum in Argentina announced that he had just excavating announced an enormous dinosaur in his South American country. This bones of Giganotosaurus were discovered by the auto mechanic, who enjoyed searching for fossils in his spare time. Because Giganotosaurus may have been somewhat larger than T-rex, paleontologists often compare the two dinosaurs, attempting to determine which was the biggest, baldest prehistoric predator. Giganotosaurus weighed up to eight tons, so if it could have wrestled with T-rex, which emerged some 30 millions years later, Giganotosaurus likely would have emerged the victor.  The remains of 75-feet long plant eating dinosaurs were found next to the Giganotosaurus fossils in Argentina, strongly suggesting that such large animals were easy pray for the jumbo carnivore. Its six foot skull and enormous

These types of dinosaurs are known as shark tooth because of their shark-like teeth. The dinosaur is obviously not a shark or lizard. In fact, the closest living relative to Carcarhodontosaurus is a member of the Crocodilia lineage. Its skull and inner ear, its brain size, are similar to some modern reptiles. This type of fossil The first discovery of Carcarhodontosaurus fossils during a North African excavation in 1927 was by Charles Deberet and J. Sovereign, an invention of the 1990s, gave a clear picture of this creature. In 1996, the paleontologist, Paul C. Mauer, of Morocco. A large skull and partial skeleton of a Carcarhodontosaurus saharicus, led by Sereno, was uncovered. It appeared to be larger than the Tyrannosaurus rex in North America and closely related to the Giganotosaurus of South America. Archeologists say the skull is only 5 feet 4 inches long. Just a year after celebrating that find, Sereno and paleontologist Stephen Brusatte found a second species: Carcharodontosa

Space-travelling dinosaur may seem like science fiction, but one dinosaur actually made it into space in 1985. Astronaut Loren Acton packed bone fragments from a historic Montana dig before boarding space lab 2, making Maiasaura the first dinosaur to orbit the earth. That might have given some paleontologists reason to grin, but what probably excites them more is taking a look back 65-80 million years before the Maiasaura's trip to the stars, when this duck billed plant eater lived among the likes of Tyrannosaurs and velociraptor.   The duck-billed Maiasaura were big dinosaur and big eaters. These herbivores had fiber-rich diets that consisted of berries, seeds and up to 20 pounds of leaves a day. However, oddly enough, its sharp, enameled teeth lined its cheeks rather than its beak. Weighing in at about 8,000 pounds, the Maiasaura were part of the Hadrosauridae family, growing to be about 30 feet long and 8 feet tall. It could navigate on either two or four legs, but perhaps had
