Dinosaurs, The Story of Remaining After

0 Comments |

The story of the dinosaurs are always interesting. The mystery that enveloped him was always waiting to go on and on dikuak. The experts had never shortage of issues on this one ancient animal. Scientific debate, the ontological question, keep scrolling: what exactly is "dinosaur" that? Is it true that dinosaurs including birds?

Linking dinosaurs to birds is the endless debates over who had started since the 19th century. At that time, dinosaur footprints commentators misconstrued as bird footprints (GLUT, Dinosaurs-The Encyclopedia, 1997). Regarded as the earliest bird, Archaeopteryx-the genus that has feathers (feathers), but also the teeth and various other characteristics of reptiles. He was crowned as the "bird of the first incontrovertible" (Currie and Zhao, 1993).

The first fossil specimen of Archaeopteryx lithographica species discovered in 1860 in Solnhofen Limestone layer (layer of Upper Jurassic age) in Franconia, Bavaria. These findings confirmed that the bird had been there in the Jurassic era, about 210 million years ago and lasted 70 million years in the Mesozoic Era. The word dinosaur is a dinosaur Initially, the combined results from the Greek word, deinos (horrible) and sauros (lizard).

Now, in general, scientists have recognized that birds are descended from dinosaurs through a process of evolution. The discovery of so far is like in the early writings: the animal-shaped dinosaur, unable to fly, but it has feathers.

Last year, in Liaoning Province, China, in a layer of fossil sites (fossil beds), the famous, Dr. Shandong Tianyu Zheng Xiaoting Museum of Nature in Pingyi. Zheng and his colleagues called his discovery as Tianyulong Confuciusi which ultimately included in the group of Saurischia which represents the ancestors of birds.

Feathers in birds serves as a heater and also functions as a signal catcher, while if it's not because there was hair in the skin, exactly what its function?

On the belief that birds are descended from dinosaurs, the discovery in Liaoning are then incorporated into the group. If the structures in the back could be called "fur", a kind of animal Stegosaurus, Triceratops, and Tyrannosaurus could be referred to as bird excess weight. Well, it turns out the mystery unsolved.
