Show the smallest dinosaur jaw is one of the dragon, chicken may only now be so great. It was also to translate it into Compsognathus. It belongs to the classification system theropod. For the theropod dinosaur evolutionary relationships of all kinds, taxonomists have different views. Lucas United States House of Vertebrate Paleontology in his book "Dinosaur," a book clearly states: Most paleontologists are now recognized, angle guanlong class is called "Long tail classes together" in the evolution of dinosaurs an offshoot. Long tail classes together, including the previously mentioned theropod class of meat and bone dragons virtual class, it can be said, the United Long tail classes is not included angle guanlong class theropods. The dinosaur's tooth structure and shape the hips, are very much like a bird. This does not mean that all classes do not belong together long tail meat category belongs to the virtual bone dragons. Show jaw Long is an excellent example.
Experts regard the past as a virtual show jaw bone dragon dragon, a member of the class, and today has changed my view.
In 1861, the first dragon fossils show jaw Archaeopteryx fossils found in Germany's Bavaria Province, Solnhofen limestone stone slate. It is only 70 cm long. Small body, large eyes and relatively large head, show that it is the individual young dragon jaw. In 1972, the second shows the dragon's jaw fossil specimens found in the south of France, its second year than the first one specimen. The United States the authority of Vertebrate Paleontology Oscar material Roma completed in 1978, all of Long jaw fossil specimens show the research. His findings so that people have a deeper understanding of this dinosaur. Long lightweight body structure show jaw, looks delicate than most dinosaurs. It has slender, flexible neck, short forelimbs and long hind legs, tail and longer. There are holes in its skull, and thus become more compact. Teeth small and exquisite, curved and very sharp, all the mandibular teeth are long before the eye socket. Show the name of the dragon jaw means it has a beautiful jaw. Its forelimbs with three fingers, only the first and second fingers can be bent, and the third refers to only one knuckle. It was the pubic-like boots. Neither of these features appear in the large carnivorous dragons, the dragon does not appear in the virtual class in the bone, so it is the most primitive end of dragons together. In Germany found a jaw fossil specimens show the abdominal cavity, was found over a small lizard extinct. Start had mistaken it's youngest son, that it is ovoviviparous, and by Professor Ostrom after the truth: that is its last meal before his death. |
