Amargasaurus was small for a sauropod, measuring 9 to 10 meters (30 to 33 feet): 304 in length and weighing approximately 2.6 metric tons (2.9 short tons). It followed the typical sauropod body plan, with a long tail and neck, a small head, and a barrel-shaped trunk supported by four column-like legs.The neck of Amargasaurus was shorter than in most other sauropods, a common trait within the.
Amargasaurus was a Diplodocoid which lived in the Early Cretaceous.It was small for a sauropod, reaching 10 meters (33 feet) length. It would have been a quadrupedal herbivore with a long, low skull on the end of a long neck. However, this dinosaur sported two parallel rows of tall spines down its neck and back, taller than in any other known sauropod. These spines have been reconstructed.As distinctive as it was, Amargasaurus appears to have been closely related to two other unusual sauropods: Dicraeosaurus, which was also equipped with (much shorter) spines emanating from its neck and upper back, and Brachytrachelopan, which was distinguished by its unusually short neck, probably an evolutionary adaptation to the types of food available in its South American habitat.Amargasaurus is a genus of sauropod dinosaur from the Early Cretaceous Period. It could reach a length of 10 meters (33 feet). A distinctive feature of this dinosaur are the two parallel rows of tall spines down its neck and back, taller than in any other known sauropod. It is an example of Convergent Evolution; with Thyreophoran-like, almost Spinosaurian dorsal, cervical, and caudal vertebral.
Amargasaurus is a genus of sauropod dinosaur from the Early Cretaceous epoch of what is now Argentina. The only known skeleton was discovered in 1984 and described in 1991, forming the holotype specimen of the single species Amargasaurus cazaui. The skeleton is nearly complete, including a fragmentary skull, making Amargasaurus one of the best-known sauropods from the Early Cretaceous.
Amargasaurus is a sauropod from Argentina. It lived in the early Cretaceous, and had two large rows of spines aligning its back. Amargasaurus was a new animal introduced to Carnivores: Dinosaur Hunter in the June 20, 2012 update. The Amargasaurus is also very fast for its size, making the speed versus mass issue with Stegosaurus seem minor in comparison. According to Tatem Games, it was.

Amargasaurus was a relatively small and short-necked dinosaur that belonged to a group known as diplodocoids.It was unusual because it had a double row of spines running along its neck and back that became a single line down its tail. There may have been a web of skin running between the spines, forming a double sail.
Amargasaurus is a wild dinosaur available in the downloadable booster pack. It lives in savannah and temperate areas. Amargasaurus is a medium sized sauropod from Early Cretaceous Argentina and part of the Dicraeosauridae family, a branch off of the Diplodocoida family. It is related to the Jurassic Diplodocus and Apatosaurus, but its closest relatives in its family have much shorter necks.
Amargasaurus Amargasaurus was an unusual looking sauropod, it had a double row of spines running from its neck to its tail vertebrae. Scientists believe that its sail may have acted as a defense mechanism, preventing other dinosaurs from biting its neck.
Reconstruction of Saltasaurus loricatus, by Lady of Hats. The name of the other lineage, Macronaria, means 'big nostrils', and one of the notable features of this clade is, indeed, a great expansion in the size of the nares, the opening for the nostrils in the skull (though whether the size of the nares directly corresponds to the size of the actual nostrils is, I suppose, another question).

Dimetrodon' classification follows: Kingdom Animalia (animals) Phylum Chordata (chordates) Subphylum Vertebrata (vertebrates) Superclass Tetrapoda (tetrapods - having four legs) Class Synapsida (synapsids) - these include the mammals, sphecodonts, basal therapsids, caseasaurs, and pelycosaurs.
Quetzalcoatlus was a huge, flying, prehistoric reptile, found in Texas. It was a late Pterosaur, and related to the dinosaurs. It lived during the Cretaceous, going extinct in the K-T extinction.
ANATOMY Deinonychus was a lightly built, fast-moving, agile, bipedal (walked on two legs), bird-like dinosaur. It was built to kill. This meat-eater had a curved, flexible neck and a big head with sharp, serrated teeth in very powerful jaws.
CLASSIFICATION Nothosaurs were reptiles but not dinosaurs. They are classified as: Vertebrata Tetrapoda Diapsida - these include all the reptiles (except turtles) and birds. They are distinguished by having two holes in the rear upper part of their skulls and two holes behind the eyes. Sauropterygia (which includes both nothosaurs and plesiosaurs).
T. rex Learning Activities for elementary school children. Tyrannosaurus rex, the largest meat-eating dinosaur (except, perhaps, for Giganotosaurus). T. rex walked on two powerful legs with claws, had tiny two-fingered arms, and a slim, pointed tail that provided balance and quick turning while running.
