10 fossils that changed the view of dinosaurs
The megalosaur (1676), the first dinosaur found. When part of his thigh was discovered in the UK in 1676, Professor at Oxford University, took her for part of the leg of a giant. Only 150 years later in 1824, William Buckland named the creature the “megalosaur”. The term “dinosaurs” appeared 20 years later in 1842.
Mosasaur (1764). Bones of mosasaurs found for hundreds of years, but could not understand who they belong to. Mosasaur notable for the fact that it was first considered to be the most ancient extinct species. It was made by the French naturalist Georges Cuvier, he first suggested that some creatures could live for millions of years before humans.
Iguanodon (1820) was the second creature, which was given the definition of “dinosaur”. The teeth of the iguanodon were discovered by British geologist Gideon Mantell. He showed them various scientist, but they considered that the teeth belong to the fish or rhinos. Only a couple of years from the remains iguanaman saw a giant creature.
Archaeopteryx (1860-1862). In 1859 Charles Darwin published his famous book “Origin of species” which described the theory of evolution. Soon was found a perfectly preserved skeleton of Archaeopteryx, which razosanas in “missing link” between dinosaurs and birds. Later found a much more convincing transitional forms, Archaeopteryx but remember all.
Diplodocus (1877). Fossils of dinosaurs found in the late XIX — early XX century mostly belonged to a relatively small ornithopods or theropods, which were only a little more. The discovery of the remains of the Diplodocus revealed the existence of sauropods, a real giant, even by the standards of the dinosaurs. The average size of Diplodocus in length — 28 meters.
Maiasaura (1975) described the American paleontologist Jack Horner, also known as the prototype of the hero of “Jurassic Park” Dr. Alan Grant. After a careful study of well-preserved fossilized eggs, skeletons of young and adults, maiasaura named the first dinosaurs caring for their offspring.
Sinosauropteryx (1977). This “Dino-birds” were first discovered with primitive feathers more like fur. Thus, further study of the remains showed that the Archaeopteryx sinosauropteryx had almost nothing in common. This has forced scientists to reconsider their assumptions about the evolution of dinosaurs into birds.
Brachylophosaurus (2000). The remains of Leonardo, called paleontologists excavated the skeleton, were first found by brachylophosaurus. But since this brachylophosaurus-teen mummified before to harden, the scientists got the most perfect specimen of a dinosaur in the history of mankind. Perhaps no skeleton either before or after have not studied so thoroughly and in so many ways.
Utilizar (2010) — one of the archosaurs, the ancestors of the dinosaurs. He lived in the Triassic period, about 240 million years ago. According to paleontologists, the first true dinosaurs appeared 230 million years ago, and utilizar was as close to them, not being one of them.
UTRAN (2012). We used to think that tyrannosaurs skin was green and scaly, like a reptile. But uteran, tyrannosaurids that lived 50 million years before t-Rex, was entirely covered with feathers. Adult Tyrannosaurus Rex was the cost of the plumage, but their babies are almost certainly sported them.
We present ten of the most significant paleontological discoveries of all time. Thanks to them we know a bit better what was life in the era of dinosaurs and how it has evolved.
