Dinosaurios carnivorous

Dinosaurios carnivorous

Carnivorous characteristics of the Dinosaurios

Most of the carnivorous dinosaurios they moved on finished thin extremities in feet similar to those of the birds, equipped with three fingers of sharpened claws, that allowed to move them very fast, certainly more express than the slow herbívoros dinosaurios.

The front members were short, the compact torso, the long tail, the curved and flexible neck and the great eyes.

Evolutionary changes

The carnivorous dinosaurios evolved throughout their 160 million years of existence. Their brains increased of size, the back legs became longer and thin and its vision improved.

Teeth and Tips

The carnivorous dinosaurios had teeth or tips. The teeth of the terópodos were thin and with dagger form, with margins sawed in the leading edges and back. When the carnivore bit his prey, the sawn edges clung to the meat of the victim and they opened to step causing a deep cut. The carnivores of small size had generally a greater number of dental pieces that the great individuals. The carnivores equipped with teeth used to have longer pieces towards half of their jaws, where the muscles of these exerted a greater force when biting.

Some carnivores developed jaws that lacked teeth, in their place these terópodos without teeth had bony tips covered with an enamel layer. These tips, little adapted to crumble the meat, would have been used to break eggs.

Carnivorous types of Dinosaurios

The first carnivorous dinosaurios

The first carnivorous dinosaurios arose in the middle of the Triásico Period, does around 225 million years.

They were small and much more primitive animals that the known carnivores more than appeared later during the Mesozoico, like Tyrannosaurus rex.

• Eoraptor. Triásico, 225 million years, South America, 1 m of length.

Eoraptor is an important animal for being one of the older well-known dinosaurios, since it lived in the dawn of the Era of the Reptiles. Eoraptor was small dinosaurio that quickly moved by its surroundings with its two lengths and thin back members, which duplicated the length of the front members. He was carnivorous and it could have been as much predator as rotten. The jaws lodged numerous sawn teeth of small size. They have been discovered fossil of Eoraptor throughout the course of an old river of Argentina, which raises the question on if Eoraptor were fed on fish.

• Coelophysis. Triásico, 220 M.sa., North America, 3 ms of lonitud.

Coelophysis had an optimal constitution to run and to move with agility. In order to reduce their weight, the bones of their extremities were almost hollow, something that was helpful to an animal that depended on the speed to catch its prey. The front legs were small and probably it used to hold and to tear them the food. It could have been a herd animal, that lived and hunted in group.

• Herrerasaurus. Triásico, 220 M.sa. South America, 3 ms of length.

Herrerasaurus lived in wooded means, between ferns and coniferous. He was a carnivore of average stature and an agile and quick predator. Long and esbeltas legs conferred the agility to him to reach to prey like the rincosaurios (reptiles herbívoros, of aspect pig, dumpy, of slow movements and that moved on their four legs). Herrerasaurus had a long head and narrows, equipped with robust jaws equipped with numerous teeth sharpened and inclined backwards. The front extremities were short and the long tail. When it ran, probably it maintained On guard horizontal the tail prim as counterbalance that way to avoid to fall of you brush.

• Compsognathus. Jurásico, 145 M.sa. Europe, 1 m of length.

Small dinosaurio Compsognathus was a quick predator that ran on its long back members. The front extremities were short and were equipped with two fingers with claws. A great skull lodged numerous curved and sharpened teeth, of small size and spaced to each other. This set of teeth could not inflict serious wounded a great animal, but it turned out suitable to catch small reptiles, insects and mammals.

Great Dinosaurios Carnivorous 1

The carnivores of great size began to appear during the Jurásico Period, but their greater stature reached it in the following period, the Cretácico. Robust and powerful, equipped with sharpened teeth as knives and claws that could scratch and break heaviest of the skins, these terópodos could have vagado in small groups, single or in pair.

• Dilophosaurus, Jurásico, 190 M.sa. North America, 6 ms of length

• Allosaurus, Jurásico/Cretácico, 140 M.sa. North America, 12 ms of length

• Neovenator, Cretácico, 125 M.sa. Europe, 8 ms of length

• Giganotosaurus, Cretácico, 90 M.sa. South America, 15 ms of length

Great Dinosaurios Carnivorous 2

These are some of the giant carnivorous dinosaurios whose muscular teeth, claws and bodies perfectly were designed to pursue to their prey. Either outside in group or solitaire, these terópodos are between the formidable hunters the more of the Era of the Reptiles.

• Megalosaurus, Jurásico, 170 M.sa. Europe, 9 ms of length

• Ceratosaurus, Jurásico, 150 M.sa. North America, Africa, 6 ms of length

• Albertosaurus, Cretácico, 70 M.sa. North America, 9 ms of length

• Therizinosaurus, Cretácico, 70 M.sa. Asia, 12 ms of length

• Tyrannosaurus rex, 70 M.sa. North America, 12 ms of length
