ANTONIO DINOSAUR

Antonio dinosaur, was affectionately nicknamed 'ANTONIO'-but perhaps too hurriedly, because it now seems that the example found was female! It belongs to a gnewly-discovered species and its scientific name was given to it when the results of the first excavations were published.

It is discovered by Tiziana Brazzatti in 1995.And it is discovered remain in Europe.

Antonio Dinosaur has three classification such as Ornithischia, Ornithopoda and Hadrosauridae. It has 4 meters length, 1.3 meters height and 700 kilograms weight. There food was herbivore.

Antonio was a biped dinosaur but it could also move on four legs.It fed on plant life which it minced of with rows of hundreds of teeth. It had a flat nose like a duck's beak and lived in herbs with others of its type.

Antonio, came to light in Trieste, at the Villaggio del Pescatore (Feshermen's Village) in the Duino area. It was the oldest and most complete example of a hadrosaur dinosaur to be found in the world, giving us important information as to how this group of dinosaurs developed and their possible area of origin.

ALVAREZSAURUS DINOSAUR

Alvarezsaurus,means 'lizard of Alvarez' named after the historian Don Gregorio Alvarez. It is discovered by Bonaparte in 1991 and found in South America. It has the dimension of 2 meters length, 55 centimeters height and 8 kilograms weight. they eat carnivore and insectivore.

Alvarezsaurus, was a biped dinosaur, agile and with a very light body, its feet and long rear limbs making it a fast runner. It arms were very small and almost withered, so not much use. It neck was 'S'-shaped and its stiff tail-more than a meter long- was used by the Alvarezsaurus to keep its balance.
Alvarezsaurus was a dinosaurus closely linked to birds.

The Alvarezsaurus is classified both among dinosaurs and within groups of primitive birds. The most recent discoveries seem to suggest that they are members of the dinosaur family- but there is still some disagreement about this. Now, as then long'S'-shape neck of the Alvarezsaurus is like that of today's flightness birds, such as ostriches, emus and rheas.

ALLOSAURUS DINOSAUR

Allosaurus, means 'strange lizard'. The palaeontologist who discovered it thought that its bones were very similar to a lizard's. It was discovered in Marsh in 1877. Allosaurus remains have been found in North America, Europe, Africa, Astralia, Asia and India. It has 14 meters length, 5 meters height and 3 tonnes weight. And eat carnivore.

The enormous quantity of remains in a good state of preservation has enabled paleontologist to reconstruct the anatomy of the Allosaurus in fine detail. The Allosaurus was a powerful, agile animal,m
moving in two legs. Its skull was huge, its neck long and muscular. Its teeth curved inward and had jagged edges like a steak knife so as to cut through even the toughest skin. It would bite its prey, holding it firmly if it tired to escape. Its three-digit hands had strong, pointed claws, ideal for digging deep into its victim's flesh. It is thought that herbs of Allosaurus could have hunted for prey as large as the gigantic Camptosaurus and Stegosaurus. The head of the Allosaurus had a strange bony crest which could have been used to recognize members of a herd, or to distinguish male from female.

The Allosaurus could reach speeds of 30 kilometers an hour - with each leap measuring a good 3 meters! As it ran along, it kept its head down, its body parallel to the ground, with its tail, long and rigid acting as a balance to keep the body stable.
Many experts believe that the Allosaurous had a hunting technique very similar to today's tiger-a long wait and then attacking at the shoulder of the prey, suddenly and rapidly.
